[[File:ESRBleak3.png|thumb|175px|The infamous ESRB Leak for ''Smash 4'' which revealed the game's roster and all unannounced characters at the time.]]
A '''leak''' is a revelation of information about a game that has been released prematurely, especially without prior permission to release such information. While game developers go through great lengths to prevent leaks from occurring, it is very common for games to have important information leaked out before being officially revealed.

Leaks can either be done intentionally via third-parties for a variety of reasons, such as increasing publicity for a game or for malicious intentions, or unintentionally via oversights that can appear in officially released media.

Due to the lack of a developed infrastructure on the Internet prior to their releases, neither ''Super Smash Bros.'' nor ''Super Smash Bros. Melee'' had leaks of notable proportions prior to their release. Starting with ''[[Super Smash Bros. Brawl]]'', the significantly more developed Internet of the 21st century made leaks much more common, particularly in pre-release hype. A large amount of them, however, tend to be invariably sketchy, with the contents of these leaks often being radically different from what is actually in the game. The large amount of rumors that start as a result makes it very difficult to pinpoint which are actual leaks before their contents are officially confirmed; this is especially a concern with leaks that are purely text, as the modes of discourse with these kinds of posts tend to differ very little. In spite of this, a varying number of real leaks can emerge, though they have been historically met with backlash upon their initial posting, often either for being deemed too outlandish to be true or for "parroting" claims made by other posts.

==''Super Smash Bros. Brawl'' leaks==
As stated prior, the pre-release period of ''Brawl'' began a trend in which posts regarding unrevealed content would inundate forums and message boards. Despite the massive amount of fake "leaks", there were a few real ones, from both slipups from those directly involved in ''Brawl'' and from people who managed to obtain information about the game. Upon ''Brawl's'' release in Japan in late January 2008, leaks could then be cross-checked with the actual game; actual screenshots and videos of the game provided considerable information to players outside of Japan, most of which had not yet been revealed by the [[DOJO!!]].

===ChaosZero leak===
[[File:ChaosZero Brawl leak.jpg|thumb|An image showing ChaosZero's leak on GameFAQs, and his interaction with a moderator brushing him off as a troll.]]

ChaosZero was a user on [[GameFAQs]] that obtained information about ''Brawl'' from an unknown source, and posted what he knew on GameFAQs on October 2007. His information leaked the following:

*{{SSBB|Lucario}}, {{SSBB|Wolf}}, and {{SSBB|Sonic}} being newcomers.
*{{SSBB|Falco}}, {{SSBB|Ness}}, {{SSBB|Captain Falcon}}, and {{SSBB|Ganondorf}} returning as playable characters. He also leaked {{SSBB|Sheik}} returning as a transformation of {{SSBB|Zelda}}.
*{{SSBB|Mewtwo}} being cut.
*The [[Stage Builder]] being in the game.
*The [[Dragoon]] being an item, and how it works.
*{{SSBB|Final Destination}} returning as a stage.

Despite leaking 100% correct information, ChaosZero was treated as a troll, and was largely derided by GameFAQs users and disbelieved in general. However, after the Dragoon item was confirmed, his reputation became more positive, and he earned the nickname "The Dragoon Prophet."

===NyaseNya leak===
NyaseNya was a user on [[SmashBoards]] with an infamous reputation as a troll obsessed with Peach. Despite his reputation however, he obtained legitimate inside information of ''Brawl'', and posted it in a [http://smashboards.com/threads/brawl-playtest-massive-spoilers.126260/ thread on SmashBoards]. His information leaked the following:

*''Brawl'' having 35 playable characters (counting {{SSBB|Pokémon Trainer}}, {{SSBB|Samus}}/{{SSBB|Zero Suit Samus}}, and Zelda/Sheik as a single character each).
*{{SSBB|Olimar}} and {{SSBB|Toon Link}} being newcomers.
*Captain Falcon, Ness, and {{SSBB|Mr. Game & Watch}} returning as playable characters.
*[[Mega Man]] and [[Ridley]] not being playable characters despite being heavily speculated.
*''Brawl'' being delayed again.
*''Brawl'' being on a dual-layered disc.

NyaseNya also leaked Sonic and the exact date he would be revealed on. However, like ChaosZero above, he too was treated as a troll giving false information, despite having leaked Sonic's exact reveal date. Even the moderators of SmashBoards treated him as such, with {{Sm|Gimpyfish}} locking the thread and editing his original post to claim he was a liar.

===ShadowXOR leak===
ShadowXOR was another SmashBoards user who was able to test a build of ''Brawl'' firsthand that included yet to be revealed characters. He leaked the following:

*{{SSBB|Marth}}, Ness, and Captain Falcon returning as playable characters.
*{{SSBB|R.O.B.}} being a newcomer.

ShadowXOR was treated like the users above, but his information in particular was treated as absolutely false, since almost everyone believed R.O.B. to be a disconfirmed character after being shown as a Subspace enemy.

===Lucario/Jigglypuff/Ness leak===
[[File:Lucario-smash-2.png|thumb|Screenshot from the video confirming Lucario and Jigglypuff.]]

On January 18, 2008, a promotional video for ''Super Smash Bros. Brawl'' on the official [[Wii]] website was posted; this video accidentally leaked hidden characters in the game. Although the video was up for the entire weekend, it was not until Sunday night (Monday in Japan) that a few keen-eyed users noticed something unusual. At one point in the video, a [[Groudon]] sticker is highlighted and the faces of {{SSBB|Pikachu}}, {{SSBB|Pokémon Trainer}}, {{SSBB|Lucario}}, and {{SSBB|Jigglypuff}} can be seen in the lower right corner, signifying which characters the sticker can be used to power-up in the [[Subspace Emissary]]. At another point in the video, a [[Claus]] sticker is highlighted, that showed Ness' head alongside Lucas'. This was essentially confirmation that these characters would be playable ([http://www.youtube.com/watch?v=vfuGSKXA20w]). Additionally, many fans believed that [[Mewtwo]]'s absence confirmed that it would not be playable, a belief which ultimately came true. Upon realising their mistake, however, the developers took the video down.

===David Hayter leaking Jigglypuff===
During an October 2007 interview by UltraNeko with David Hayter, the voice actor of {{SSBB|Snake}}, he was asked which ''Brawl'' character he would most like to beat up, to which he replied Jigglypuff, inadvertently leaking it being playable in the game. Users on Neoseeker [http://www.neoseeker.com/forums/32197/t1030212-jigglypuff-confirmed/ took notice] before both UltraNeko's account and TheUltraPhoenix, a channel that archived several of her videos, had went down. An archive of the video [https://www.youtube.com/watch?v=XpaMAWp833U/ remains] on user proxyXIII's channel.

==''Super Smash Bros. for Wii U and Nintendo 3DS'' leaks==
Many fake leaks were spread around during the prerelease of ''SSB4''. The most prominent of these were the [[Gematsu leaks]], which had thousands of followers believing them in their entirety before they were proven partially inaccurate by the inclusion of {{SSB4|Robin}} and {{SSB4|Lucina}}, and disconfirmation of [[Chrom]] and eventually ''Rhythm Heaven'''s Chorus Kids, as playable characters. Other supposed leaks also proved popular, such as [[List of rumors#Palutena rumor|one showing Palutena as a playable character]] that the creator later admitted was a hoax.

The largest ''SSB4'' leak was the ESRB leak, which, unlike the Gematsu leaks, had very few followers prior to video footage being posted and subsequently taken down by Nintendo due to copyright claims, followed by the official confirmation of {{SSB4|Shulk}}, who was implicated by the leaks. The leak managed to give away a number of playable characters, stages, modes, and trophies, and is one of the largest leaks, if not the largest leak, in ''Smash'' history.

In July 2014, a supposed email from Australian classification boards, OFLC, had supposedly indirectly leaked [[Wario]] as a playable character due to his use of flatulence [http://en.reddit.com/r/smashbros/comments/2bwy5x/report_from_the_australia_classification_board_on/ contributing towards the game's rating]. Wario's playable appearance in the game was later confirmed by the ESRB leak.

Leaks for the post-release of a game became possible with the advent of [[downloadable content]].
===Battlefield Ω leak===
[[File:Battlefield Omega Developer Direct Leak.png|thumb|Battlefield Ω as seen in the E3 2013 Developer Direct.]]
In the [https://www.youtube.com/watch?v=Sc5BISnOVPM E3 2013 Developer Direct for ''SSB4''], a clip was shown that depicted {{SSB4|Mario}} and {{SSB4|Mega Man}} on the [[Ω form]] of {{SSB4|Battlefield}}, despite the Ω forms having not been officially revealed. However, very few people noticed it and the stage was brushed off as the regular Battlefield. The Ω forms were formally unveiled in the [[Nintendo Direct#Super Smash Bros. Direct 4.8.2014|April 2014 Super Smash Bros. Nintendo Direct]], with the Ω form of Battlefield being identical to what was seen in the Developer Direct.

===Jiggensteins leak===
In early May 2014, a GameFAQs user named jiggensteins posted a topic titled [https://gamefaqs.gamespot.com/boards/633202-super-smash-bros-for-wii-u/69182495 "Two New Characters."] in which they claimed that {{SSB4|Lucina}} and {{SSB4|Robin}} would be playable characters. They added that both the male and female versions of Robin would be available and that they would fight using magic.

In July 2014 this information was proven to be accurate with the official reveal of Robin and Lucina.

===Ninka/Vaanrose leak===
Prior to E3 2014, a Smashboards user by the name of Ninka Kiwi posted that he knew a friend who was playtesting ''Super Smash Bros. 4'',  though he did not divulge any specific information, other than {{SSB4|Mario}} and {{SSB4|Charizard}} having new [[alternate costume]]s, with Mario in particular having a new blue costume. Later on in July, Ninka came forward with new information, which included Lucas, Wolf, the Ice Climbers, and Snake being cut, while Shulk, Dr. Mario, Dark Pit, Bowser Jr. in the Koopa Clown Car (with all seven {{s|mariowiki|Koopalings}} as alternate costumes), and the Duck Hunt dog being new characters. While initially disbelieved and seen as too outlandish, a friend of Ninka who gave him the information, named Shun, contacted a Smashboards user by the name of Neo Zero, who revealed to him that he got the information he revealed to Ninka from his own friend, and revealed that his friend recreated and posted two of the [http://i.imgur.com/vs3UPDc.jpg new] [http://i.imgur.com/2ekzmPt.jpg palettes] on imgur, before E3 2014. While this was going on, an apparently completely independent source posted a supposedly leaked newcomer list on 4chan (containing Shulk, Chorus Men, [[Mewtwo]], [[Ridley]], [[Dixie Kong]], Duck Hunt Dog, and Bowser Jr.), containing the two characters unique to the, at the time, completely disbelieved Ninka leak. In addition to this, a person in the ''Smash'' community known as Vaanrose came forward to Neo Zero that he knew a friend who knew someone who worked at Nintendo of America's offices in Redmond, Washington, who disclosed to him that {{SSB4|Robin}}, Bowser Jr., and the Duck Hunt Dog were playable. With the screenshot proof of prior knowledge of the new palettes, and these new independent sources backing up a completely disbelieved leak, the people involved publicized this additional information legitimizing the leak in a [http://smashboards.com/threads/the-ninka-vaanrose-leak-discussion-theory.362684/ thread on SmashBoards].

The release of {{For3ds}} in Japan verified everything described by Ninka and Vaanrose, while the additions made by the 4chan variation of the leak were confirmed false.

===ESRB leak===
{{main|ESRB leak}}
One of the most notable leaks in ''Super Smash Bros.'' history took place shortly before the Japanese release of {{For3ds}}. This leak managed to reveal the entire base roster of characters, including {{SSB4|Jigglypuff}}, {{SSB4|Ness}}, {{SSB4|Ganondorf}}, {{SSB4|Dr. Mario}}, {{SSB4|Falco}}, {{SSB4|Mr. Game & Watch}}, {{SSB4|Wario}}, {{SSB4|R.O.B.}}, {{SSB4|Bowser Jr.}}, {{SSB4|Duck Hunt}}, {{SSB4|Dark Pit}}, and {{SSB4|Shulk}}, none of whom were announced at the time. Although initially considered obviously fake by many, the leak gained momentum and popularity after several gameplay videos featuring Shulk, Bowser Jr., and Ganondorf were released and, shortly thereafter, Shulk was officially announced. YouTube video footage of these characters was shortly taken down by Nintendo of America.

The leak additionally featured several photos of the content sent to ESRB, one notably featuring a trophy of the {{uv|Fire Emblem}} character Tharja, which does not appear in the final game. Due to her revealing outfit and her trophy's omission from the game, it is believed that the trophy was cut to maintain a lower content rating.

===Ganondorf leak===
[[File:Ganon Leaked - Official.png|thumb|Ganondorf as seen in the video.]]
{{SSB4|Ganondorf}} was accidentally shown prior to his reveal in a video posted by Nintendo on August 29th, in which he can be seen offscreen while Pikachu is taunting. This same video was later re-uploaded on September 1st, edited so Ganondorf could no longer be seen offscreen. The [https://www.youtube.com/watch?v=omeOylQYkuU original video] is now unlisted.

Ganondorf was mentioned on October 10th by Sakurai in his "Pic of the day" post, discussing the Home-Run Contest. At the end of the post, he remarks, "I wonder if Ganondorf gives you some advantage," despite Ganondorf having not yet been formally revealed.

Ganondorf was officially revealed on October 15th, and is one of the few characters to be leaked multiple times by official material.

===Great Cave Offensive leak===
On October 5th, 2014, the official Super Smash Bros Facebook page posted a picture recapping the pictures of the day of the past week. Alongside a picture of the Orbital Gate and the 3DS version's title screen, there was also a picture of Kirby and Pikachu riding in a mine cart in a previously unseen stage. The image was captioned as "Kirby's going for a ride in a mine cart. Well, this situation looks familiar. This stage has some rules that are rare in the Smash Bros. series."

The leak was later confirmed as [[The Great Cave Offensive]], and was revealed officially in the Super Smash Bros. for Wii U 50-Fact Extravaganza.

===Amazon leak===
About a month prior to {{forwiiu}}'s release in North America, online retailer {{s|wikipedia|Amazon.com}} put up a page to allow for consumers to reserve copies of the game. On the product description for the game, however, information was provided that seemed to suggest a variety of new game modes for the Wii U game:
{{cquote|Whether you're creating stages on the GamePad, competing in challenges crafted by Master Hand and Crazy Hand, or outwitting your opponents in a brand new board game mode, there’s no doubt that the ultimate Smash Bros. game has arrived.}}

A mode involving Master Hand and Crazy Hand was later revealed by Sakurai [[:File:SakuraiMasterCrazyOrder.jpg|in a Miiverse post]], and had previously been implicated by unused content found in the 3DS version. The "board game" and "creating stages" modes, however, had never been previously mentioned on Miiverse or other official material, suggesting that unknown information was still available about the game.

The Super Smash Bros. for Wii U 50-Fact Extravaganza confirmed [[Special Orders]] as a mode involving challenges made by Master Hand and Crazy Hand, [[Smash Tour]] as a board game mode, and a revamped [[Stage Builder]] for the Wii U game, verifying everything implicated in the leak.

===Roy and Ryu data===
Contained in version {{H2|List of updates (SSB4-3DS)|1.0.6}} of {{for3ds}} were new, unused, sound files, seemingly implicated DLC that had yet to be announced. These included, among other things, a victory fanfare "snd_bgm_Z83_F_Roy_3DS" for [[Roy]], which was a duplicate of the existing ''Fire Emblem'' [[victory theme]], suggesting he would also return as DLC in the same way [[Mewtwo]] and [[Lucas]] did, and two files named "snd_bgm_Z81_F_Ryu_3DS" and "snd_bgm_SF01_SF2_Ryu_3DS", both named in reference to [[Ryu]] from [[Capcom]]'s famous {{uv|Street Fighter}} series of fighting games; the files contained the victory theme and Ryu's theme, respectively, from ''{{s|wikipedia|Street Fighter II}}''. The discovery of these files was first reported by game modder shinyquagsire23 [http://www.reddit.com/r/smashbros/comments/32nymz/smash_update_106_decrypted_first_observations/ in a reddit thread] posted on April 15th, 2015, and was corroborated later that same day by homebrew developer [https://twitter.com/crediar/status/588452304539418624 crediar], who confirmed the files were not present in the game's Wii U version, and the staff of [https://twitter.com/CuttingRoomWiki/status/588467223833882627 The Cutting Room Floor], a [https://tcrf.net/ wiki] that specializes in unused video game content.

More unused files beyond these were present, among them being the remix used for the {{SSB|Dream Land}} stage in ''Super Smash Bros.'' and ''Super Smash Bros. Melee'' and a second ''Kirby'' theme, the ''{{SSB4MusicLink|Kirby|Forest Stage}}'' theme from ''Kirby Air Ride''. The presence of the Dream Land remix and another forest-themed track suggested that the stage would be future DLC as well. A piece of corroborating evidence for this was also found in {{b|Classic Mode|SSB4-3DS}} following the 1.0.6 update, as ''Kirby'' characters would sometimes be fought on {{SSB4|Battlefield}} instead of the existing {{SSB4|Dream Land}} stage, with Battlefield presumably being used as an error handler for an expected but not present ''Kirby'' stage.

Four days later, following the discovery of these files, shinyquagsire23 reported finding [http://www.eventhubs.com/news/2015/apr/19/5-new-potential-character-slots-found-super-smash-bros-3ds-files-more-stage-slots-also-discovered/ more hidden files] in the game. [http://www.eventhubs.com/images/2015/apr/19/5-new-character-slots-found-super-smash-bros-3ds-files-more-stage-slots-also-discovered/ An image] of the character data was released; five unused character slots after Mewtwo are named "Mario", presumably as a placeholder for additional DLC characters. Additionally, shinyquagsire23 reported discovering changes to stage data table. The number of inaccessible stage slots had, according to the article, increased from 4 to 14; this includes the slots for Ω forms, meaning there was space for up to 7 more stages and their Ω forms. The discovery of these files suggested there were more stages planned for DLC beyond Dream Land.

Despite the files being present in the update for a long time, it was not until June 13th, 2015 that they were confirmed to represent real DLC content. On that date, [https://twitter.com/RandomTBush Random Talking Bush], an administrator of and contributor to the site The VG Resource, revealed that he had successfully downloaded the 1.0.8 update of the Japanese version of ''SSB4'' from Nintendo's servers before it was set to release; he then proceeded to datamine its contents and post links to them on his twitter account, showing the characters' [http://www.reddit.com/r/smashbros/comments/39opwc/roy_and_ryu_confirmed_for_smash/ ending videos], official art, costumes, and trophies, along with the rest of the planned DLC. Later during that day, crediar was able to test out Lucas, Ryu and Roy before their release on [http://www.twitch.tv/crediar his Twitch stream] by editing the files to run over Mario.

Parts of the stream were [https://www.youtube.com/watch?v=aYt-_nukUx8&feature=iv&src_vid=ugtRN2O24_8&annotation_id=annotation_1995371355 uploaded to YouTube], but have since been taken down by [[Nintendo]] of America on copyright claims, similar to how they took videos down after the ESRB leak. All videos on major YouTube channels talking about the leak were also taken down, including those on [https://www.youtube.com/user/GameXplain GameXplain] and the late {{s|wikipedia|Desmond Daniel Amofah}}’s Etika World Network.

Roy, Ryu, Dream Land (64), and all other elements implicated as DLC were formally announced and released on June 14th, 2015. Notably, Ryu's victory theme was replaced with a remix as opposed to the direct rip from ''Street Fighter II'' present in the 1.0.6 data; also, the ''Forest Stage'' track that was found in the 3DS version would end up only being used on Dream Land (64) on the Wii U version, as the 3DS version ended up using ''{{SSB4MusicLink|Kirby|Ice Cream Island}}'' as its alternate track instead. Furthermore, exactly 7 other stages aside from Dream Land were added to the 3DS version of the game via DLC and updates, including {{B|Duck Hunt|stage}}, which came free after version {{H2|List_of_updates_(SSB4-3DS)|1.1.1}}, and [[Suzaku Castle]], which became available with the same update that Dream Land did.
{{Clear}}

==''Super Smash Bros. Ultimate'' leaks==
Several rumors regarding a ''Smash'' title for the then-unnamed [[Nintendo Switch]] pervaded in the time preceding the announcement of ''[[Super Smash Bros. Ultimate]]'', many of them centering on the debate if the system would, assuming a ''Smash'' title was going to release, receive a port of an existing title or a completely new one. Following the game's announcement in 2018 and the release of more information in the months that followed, nearly all of them were proven false. Afterwards, however, real leaks began to emerge, ranging from minor ones, such as the premature confirmation by a former employee that Bandai Namco would return to develop the game, to much larger ones, such as the dispersion of an illegal copy of the full game two weeks prior to release, which in itself leaked several details regarding the game.

===Confirmed Vergeben leaks===
{{main|Vergeben leaks}}
On May 16th, 2018, a user known as [https://gamefaqs.gamespot.com/boards/234547-super-smash-bros-for-nintendo-switch/76614511 Vergeben] posted a thread on GameFAQs, claiming he had a reliable source with information on the character roster of the then teased but still unrevealed ''Super Smash Bros. Ultimate''. He would later follow up his statements with multiple others later on, most of which had correct information.

At present, the following are the claims made by Vergeben that have been confirmed:
*{{SSBU|Ridley}}, {{SSBU|Simon}}, {{SSBU|Isabelle}}, {{SSBU|Incineroar}}, and {{SSBU|Ken}} would appear as newcomers, the latter as an [[Echo Fighter]] of {{SSBU|Ryu}}.
*All characters from ''[[Super Smash Bros. 4]]'' would return, as well as {{SSBU|Snake}} and the {{SSBU|Ice Climbers}}.
*Over half a dozen newcomers would be included (specifically eleven in the base game).
*Decidueye, Lycanroc, [[Mimikyu]], and [[Isaac]] would not be playable, the latter instead returning as an [[Assist Trophy]].
*{{SSBU|Banjo & Kazooie}}, either Luminary or Erdrick (Luminary and Erdrick both being present under the banner of {{SSBU|Hero}}), and {{SSBU|Terry}} would be part of the Fighters Pass Vol. 1.
*{{SSBU|Terry}} would appear as the fourth character in the Fighters Pass Vol. 1.
*The final fighter in Fighters Pass Vol. 1 would not be from [[List of companies with minor representation#Ubisoft|Ubisoft]], [[Bandai Namco]], {{iw|wikipedia|Level-5|company}}, {{s|wikipedia|Nippon Ichi Software}}, {{s|wikipedia|Nihon Falcom}}, [[Capcom]], [[Sega]], [[Konami]], [[List of companies with minor representation#Arc System Works|Arc System Works]], [[List of companies with minor representation#Spike Chunsoft|Spike Chunsoft]], [[List of companies with minor representation#Marvelous|Marvelous]], {{s|wikipedia|Epic Games}}, {{s|wikipedia|Touhou Project}}, [[List of companies with minor representation#Bethesda Softworks|Bethesda Softworks]], [[List of companies with minor representation#Koei Tecmo|Koei Tecmo]], {{s|wikipedia|Activision}}, {{s|wikipedia|Blizzard Entertainment}}, {{s|wikipedia|NetherRealm Studio}}, [[Microsoft]], [[Square Enix]], or {{s|wikipedia|Sony Interactive Entertainment}}.
*The Mii Fighter costumes releasing with {{SSBU|Byleth}} would be [[Altair]], [[Cuphead]], a [[Rabbid]] hat, and two Mega Man costumes.

===Base Game Rumors===
====Battlefield and E3 2018 Booth leak====
{{ImageCaption|File:M0HLeak.jpeg|File:KoHLeak.png|width1=200px|width2=200px|align=right|caption=Left: Master0fHyrule's image<br>Right: GU KingofHeart's image}}
On April 24th, 2018, a YouTuber by the name of "Master0fHyrule" claimed on Twitter that a source had told him that [[Bayonetta]], [[Duck Hunt]], and [[Shulk]] would return as playable characters for the upcoming game. On the same day, he claimed to have seen the new version of [[Battlefield]] and uploaded an image of which he described as "a small piece of it from the Top-Down view".<ref name="ResetEra">[https://www.resetera.com/threads/rumor-smash-bros-e3-info-screenshot-leaked.38549/ "RUMOR: Smash Bros E3 info + screenshot leaked?" - ResetEra]</ref>

A day later, a YouTube user by the name of "GU KingofHeart" published a video in which he claimed that he received information about display items being featured at the ''Super Smash Bros.'' section of Nintendo's then-upcoming E3 2018 booth. He claimed that his source was the same source that leaked that Nintendo's E3 2017 booth would have a New Donk City-themed area, which turned out to be true.<ref name="ResetEra/> He revealed the following:

*[[Bayonetta]]’s handguns and boots
*[[Captain Falcon]]'s helmet
*[[Fox]]’s Blaster
*[[Link]]’s Master Sword
*[[Marth]]’s Falchion
*[[Shulk]]’s Monado
*A [[Golden Hammer]]
*A {{S|inkipedia|Splattershot}} from ''{{S|inkipedia|Splatoon}}''

These supposed items hinted the return of Bayonetta, Captain Falcon, Fox, Link, Marth, and Shulk as playable characters, the return of the Golden Hammer as an item, and the inclusion of greater ''Splatoon'' representation. It also supported Master0fHyrule's claims of Bayonetta and Shulk returning.

In addition to the display items, GU KingofHeart also uploaded an image of what he claimed was the center of the new Battlefield. The image lined up with Master0fHyrule's previous image.

All of the uploaded videos and tweets were deleted soon after they were posted. Discussion of the two leaks mostly remained within ResetEra and SmashBoards. On June 12th, 2018, the day of Nintendo's [[E3 2018]] event, a new trailer for the previously untitled ''[[Super Smash Bros. Ultimate]]'' was demonstrated. In the trailer, the new {{SSBU|Battlefield}} was revealed and officially confirmed both Master0fHyrule and GU KingofHearts' leaked images as real. The trailer also confirmed that every previous fighter would return, confirming the leaked characters in the process. At Nintendo's booth, all of the display items leaked by GU KingofHearts' source were confirmed to be real.

====Rendering engine leak====
On May 9th, 2018, a former software engineer and graphics programmer for Bandai Namco<ref>[https://sc.linkedin.com/in/tiago-sonobe-39281828/eng Tiago Sonobe's profile on LinkedIn]</ref> named Tiago Sonobe stated on Twitter that after his August 2016 departure from the company, work had begun on a new ''Super Smash Bros.'' game using the in-house rendering engine which Sonobe had developed. Following the spread of the tweet, Sonobe's Twitter account was entirely deleted.<ref>[https://mynintendonews.com/2018/05/10/a-nintendo-software-engineers-tweet-suggests-that-bandai-namco-is-working-on-smash-switch/ "A Nintendo Software Engineer’s Tweet Suggests That Bandai Namco Is Working On Smash Switch" - My Nintendo News]</ref>

====E3 2018 4chan leak====
On June 11th, 2018, one day before the [[Nintendo Direct]] at E3, an anonymous user on [https://archived.moe/v/thread/419829152 4chan] leaked information about the upcoming Nintendo Direct. In it they said:

*All previous characters will return.
*{{SSBU|Daisy}} and {{SSBU|Ridley}} are newcomers.
*Old stages are returning.
*[[Bomberman]] will be an [[Assist Trophy]].
*Title is Super Smash Bros. Ultimate.
*Release date is December 7, 2018.
*[[Clone]] characters receive an icon next to their name (later revealed to be indicating Echo Fighters).

As with many ''Brawl'' leaks, the leaker was considered a troll and mocked for their claims. During the Direct, his information was confirmed mainly factual.

The leak made a few notable errors, such as claiming that {{SSBU|Lucas}} was an Echo Fighter, that {{SSBU|Inkling}}'s Final Smash would be a [[Squid Sisters]] concert which would cause the screen to zoom in, and that all stages would have a [[Final Destination]] and [[Ω form]] (which are the same thing). In reality, Lucas is treated as a fully separate character from Ness, the Squid Sisters were revealed to be an [[Assist Trophy]] with the same function while Inkling's Final Smash was confirmed to be [[Killer Wail]], and it was confirmed that stages would have both a Ω form and a [[Battlefield form]]. However, given that the rest of the information was correct, as well as the fact that the same user correctly predicted the title and gameplay style of '' Super Mario Party'', another game featured in E3 2018, it is likely these errors were made from misinterpretation or assumption rather than being evidence of a false leak.

====Loz18 E3 2018 leak====
On June 11th, 2018, GameFAQs user Loz18 made a [https://gamefaqs.gamespot.com/boards/234547-super-smash-bros-ultimate/76696436 thread] about ''Ultimate'' before its E3 reveal. In the first post, he stated the following:

*All previous characters will return.
*Inkling's ability to recharge ink and their special moves being [[Super Jump]], [[Splattershot]] (albeit referred as "Tentatek Attack"), and [[Splat Bomb]] (albeit referred as "Bomb Attack").
*Ganondorf's outfit is based off of ''Ocarina of Time'' and his up smash changed from a kick to a sword attack.
*Zelda's outfit is based off ''A Link Between Worlds''.
*Link's moveset is almost unchanged, but the {{B|Bomb|Link}}s from ''Twilight Princess'' are replaced with [[Remote Bomb]]s from ''Breath of the Wild''.

Two days after the E3 reveal, he made [[List of rumors#Loz18 leaks|another claim]] about an August [[Nintendo Direct]]. Although a ''Super Smash Bros.''-themed Nintendo Direct was confirmed for August 8th, the rest of his information was proven inaccurate to various degrees.

====Castlevania music leak====
[[File:CastlevaniaMusic.png|thumb|right|The misnamed video.]]
The night of August 7th, 2018, close to the airing of the ''Super Smash Bros. Ultimate''-centered [[Nintendo Direct]] the following morning, the [https://www.youtube.com/watch?v=APSRqnT8hvo YouTube video] for the Galaga Medley on Nintendo's ''Super Smash Bros.'' channel that was previously confirmed the week prior was renamed to "Bloody Tears / Monster Dance", both of which are tracks from ''{{s|wikipedia|Castlevania II: Simon's Quest}}''. It was later properly renamed back to "Galaga Medley".

Following the Direct, which announced {{SSBU|Simon}} and {{SSBU|Richter}} as new playable characters from the {{uv|Castlevania}} series, "Bloody Tears / Monster Dance" was properly uploaded to the website. Due to this incident, all the music previews were renamed to numbers, with each new upload incrementing by one.

====Spirits mode leak====
Shortly after the August 2018 ''Smash'' Direct, Twitter user NoctuleScent made [https://twitter.com/noctulescent/status/1027204063811850240 a twitter thread] documenting his attempt at deciphering the name of an unannounced [[mode]], shown in the Direct as part of ''Ultimate'''s menu, hidden behind a pixelated blur filter and to be revealed at a later date. The tweet claimed that the mode's name was "Spirits", discovered thanks to a "mistake from the editing team", in which parts of the name can be seen for 2 frames as the menu zooms away from deselecting Smash mode. [https://twitter.com/noctulescent/status/1027212726370807808 Another tweet] shows the name with both frames juxtaposed with image editing software for better clarity. This was corroborated by another Twitter user, [https://twitter.com/JoePinesIsDumb/status/1027323548182953985 Joe Pines].

Shortly after the original tweet, [https://twitter.com/noctulescent/status/1027206737210867712 another one] from the original user explained that the same method can be used for the Japanese version of the Direct, revealing a direct translation of "Spirits" in katakana ({{ja|スピリッツ|Supirittsu}}, ''Spirits''). [https://twitter.com/noctulescent/status/1027541204723007488 Another tweet] claimed that the logo above the name resembles a {{s|wikipedia|magatama}}, an item often associated with spirits, further drawing a connection to the name.

In the Super Smash Bros. Direct on November 1st, 2018, the formerly unknown mode was revealed as "{{B|Spirits|menu}}", confirming the leak.

====CoroCoro stages leak====
The September 2018 issue of CoroCoro, a Japanese magazine, featured information about ''Ultimate'': though most of it was a retread of what had been in the August 2018 Smash Direct, the magazine stated that the game would have 108 total stages. This was contrary to the aforementioned Direct, which instead stated that the game would feature 103 stages. While this could be assumed as a printing error, many users noticed how this number perfectly matched with the [https://www.ssbwiki.com/File:Stage_Select_Ultimate_Normal.jpg stage selection screen] shown in the Direct, with room for six more spots.

The October issue of CoroCoro dropped the stage count back to 103<ref>https://twitter.com/DartsEnthusiast/status/1053692372322803712</ref>. It is unknown if the September issue's count was a misprint or something that they were not allowed to reveal, although it should be noted that 5 stages were released as DLC for the first Fighters Pass, bringing the stage count to 108.

====No new Codec Conversations====
On September 8th, 2018 in Fan Expo Boston 2018, a fan asked David Hayter (the English voice actor for {{SSBU|Snake}}) about ''Ultimate''<ref>https://www.youtube.com/watch?v=iFSVVlFSbFw#t=1389</ref>, and Hayter replied that more [[Codec Conversations]] hadn't been recorded yet. This led some fans to believe that the Codec Conversations would not be in the game at all. Some that played the demo cited the removal of the [[Star Fox Smash Taunt]] in [[Lylat Cruise]], though others guessed that it simply was disabled for the demo. As {{SSBU|Pit}}'s [[Star KO]] voice clip was completely new, some believed that both [[Palutena's Guidance]] and the Codecs could have been rerecorded. Others noted that Hayter was likely bound to a non-disclosure agreement and thus was forbidden from discussing anything not permitted by his contract; however, Hayter himself brought up the topic of Codec Conversations without being asked specifically about it, even after openly acknowledging that he probably was not supposed to say anything, which makes it unlikely that he was trying to obfuscate the truth. Hayter also expressed dismay on not being able to record new lines for ''Ultimate'' codecs. Additionally, {{s|wikipedia|Takeshi Aono}}, Roy Campbell's Japanese voice actor, passed away in 2012, and future ''Metal Gear'' titles do not feature the character out of respect for Aono. This made it more likely that no new Codec Conversations would be recorded.

It was later revealed from early copies of ''Ultimate'' that the Codec Conversations from ''Brawl'' return, but that there are no unique Codec Conversations for characters (re-)introduced in ''Smash 4'' or ''Ultimate''. This is in line with Hayter's previous statements that he had not recorded any new voice lines for the game. However, Palutena's Guidance did receive new voice lines in ''Ultimate'' for veterans not in ''Smash 4'', {{SSBU|Piranha Plant}}, and redesigned characters.

====Noatesty leaks====
On September 14th, 2018, Reddit user Noatesty made several posts where they claimed to be a playtester for ''Ultimate'' and shared several details about then unrevealed content. 

In their first [https://www.reddit.com/r/smashbros/comments/9fnyga/unannounced_content/ post], Noatesty claimed that {{SSBU|Ken}} and {{SSBU|Incineroar}} would be the final playable characters in the base game, and that [[Flies & Hand]] from ''Mario Paint'' would be an Assist Trophy. They also shortly described [[Spirits]], comparing them to ''Brawl''{{'}}s [[stickers]], detailed [[Fishing Rod]]'s functionality as a tether recovery, and claimed that the game would receive a day one patch with new modes, and that the internal codename of the game was "Cross2".

In their second [https://www.reddit.com/r/SmashBrosUltimate/comments/9fmsau/isabelle_is_not_an_echo_fighter/e5y1ub0/?context=3 post], Noatesty further described {{SSBU|Isabelle}}'s moveset, claiming that her forward, back, up and down aerials, which had not been shown at the time, were similar, if not identical, to their respective counterparts in {{SSBU|Villager}}'s moveset.

In their third and final [https://www.reddit.com/r/SmashBrosUltimate/comments/9fk0yw/potential_dlc_fighters/e5y2g4v/?context=3 post], Noatesty claimed that a {{SSBU|Piranha Plant}} was going to be the first downloadable character, and said that it did not have its iconic fireball attack anywhere in its moveset. According to them, it was only accessible via a debug menu in the test build they played. They also described Incineroar's moveset, claiming that it would mostly consist of wrestling moves; its [[Alolan Whip|side special]] appeared to not be based on any existing {{uv|Pokémon}} move, but instead had it summon ropes and launch opponents against them. It also had a purple alternate costume that they claimed resembled ''{{uv|Sonic}}'' character Big the Cat. 
 
On November 1st, 2018, Ken, Incineroar and Piranha Plant were revealed as playable characters, the lattermost as DLC, while Flies & Hand was revealed as an Assist Trophy; it would also reveal that the mysterious mode teased in the previous direct was called Spirits and featured collectibles similar to stickers. Later that day, the Nintendo Treehouse stream also validated Noatesty's claims about Isabelle's and Incineroar's movesets. On November 28th, 2018, it was announced that the game would receive a day one update, although the contents of the update were not disclosed in detail. After the update was released, it was revealed that downloading it would enable online modes and add a Hard difficulty setting to [[World of Light]]; it is unclear if these are the modes that Noatesty was referring to. Datamining the game also revealed that the internal project name was indeed "Cross2".

====Ken leak====
{{ImageCaption|File:SSBU Ken Screenshot Leak.jpg|File:SSBU Ken screenshot leak demo version recreation.jpg|width1=120x120px|width2=99x99px|align  = right|caption='''Left Image:''' The leaked image of Ken along with [[Ivysaur]],<br>[[Pichu]], and Pac-Man.<br>'''Right Image:''' A recreation of the image taken in the demo version<br>using Pikachu and Ryu instead of Pichu and Ken.}}
On September 21st, 2018, an anonymous 4chan user posted a cropped screenshot of Ken Masters from the {{uv|Street Fighter}} series on [[Moray Towers]]. Later, the user uploaded the full screenshot to the same thread, showing off Pichu, Ivysaur, and Pac-Man taunting alongside Ken on the Moray Towers stage. Allegedly, Ken's model is not a port of another game, but a new model altogether.

Some users pointed out that the portrait of Pichu had its ear cut off, which actually matched up with the E3 reveal trailer. Ken was partially standing on a metal surface where his shadow does not appear under his foot: SmashBoards user DJ3DS [https://smashboards.com/threads/smash-ultimate-discussion-warning-possible-spoilers-leaks.434391/page-4859#post-22462663 recreated the shot] in the demo build with Pikachu and Ryu instead of Pichu and Ken; the shadow is missing from the metal surface in the demo build, meaning that the error in the leak does in fact exist in the game.

{{SSBU|Ken}} was announced on the November 1st Super Smash Bros. Ultimate Direct, with his model and render matching with the one in the photo.

====Piranha Plant 4chan leak====
On September 24th, 2018, an anonymous 4chan user made a [https://archived.moe/v/thread/432868409/ thread] claiming that the final three newcomers in ''Ultimate'' would be Incineroar, Ken (as an Echo Fighter based on Ryu), and Piranha Plant. They also elaborated on Piranha Plant's playstyle, saying that it would be in a vehicle of some sort in a similar vein to Bowser Jr.

On November 1st, 2018, {{SSBU|Incineroar}}, {{SSBU|Ken}}, and {{SSBU|Piranha Plant}} were confirmed to be playable fighters in the final pre-launch Super Smash Bros. Ultimate Direct. However, while the 4chan user's assertion that Ken would be a Ryu Echo Fighter was correct, their claim that Piranha Plant used a vehicle was proven to be inaccurate, with it instead being in a pot or Warp Pipe (depending on the costume selected) and walking on its roots which extend from the bottom of its vessel, though this was more likely a misconception than deliberately false information.

====Healing Sprout leak====
[[File:Growthleak.png|thumb|150px|The item, seen in the trailer.]]
On October 26th, 2018, Nintendo of America [https://twitter.com/NintendoAmerica/status/1055519359622410241 uploaded a video] onto Twitter showcasing and promoting their Wendy's College Tailgate Tour, with several clips of full gameplay intertwined with demo gameplay. For a split second, on {{SSB4|Mute City}}, a circular unrevealed item with a stem and two leaves could be seen; fans quickly took notice that this item bore a strong resemblance to the [[goldensununiverse:Growth Psynergy series|Growth Psynergy]] from ''{{s|goldensununiverse|Golden Sun: Dark Dawn}}''.

The item was revealed to be [[Healing Sprout]] on November 1st, 2018, a new item unrelated to Growth Psynergy. However, [[Isaac]] was confirmed on the same day to return as an Assist Trophy, meaning that {{uv|Golden Sun}} representation returned nonetheless.

====Completed Game leak====
Two weeks prior to the release of ''Ultimate'', a leaked copy of the game was distributed across the internet, in part due to an accidental release in Mexico. Nintendo took steps to issue copyright strikes on YouTube videos using data mined content, while fans worked to isolate spoilers, particularly the [[World of Light]] story mode, from those that had played the leaked version. As the entire roster and selection of stages were all revealed before the leaks, very little info shown off from those were not already known. However, the following information that was previously unknown was shown off:
*The existence of [[Dharkon]] and The Dark Realm were leaked, as well as the appearances of [[Crazy Hand]], [[Marx]] and [[Ganon]] as bosses of The Dark Realm (along with the previously revealed [[Dracula]]). 
*A majority of the music tracks present in ''Ultimate'' were leaked, and several YouTube channels that had uploaded the music were taken down (such as Crunchii, a channel that Nintendo had previously trusted to release a short loop of the Menu theme from the E3 2018 demo). 
*All 1297 of the base game [[spirits]] were leaked as well, with Camilla’s and Mythra’s spirits being shown for the first time with censored artwork. 
*The functionality of [[Squad Strike]] was shown off after months of speculation about what it would be (despite the mode being revealed during a [[Nintendo Direct]], many fans were split on how the mode worked).
*The process and order for [[unlockable character|unlocking fighters]] was discovered and demonstrated.
*The [[character select screen]] with Echo Fighters stacked was first shown off in the early release leaks, indirectly showing off that it would also stack {{SSBU|Mii Fighter}}s. It was also shown that the stacked option will not affect single player modes or Squad Strike.
*The exact parameters of every character’s attributes and movesets were made public, including a beta version of {{SSBU|Piranha Plant}}’s, showing it to formerly be the slowest character in the game.

===Fighters Pass Vol. 1 Rumors===

====Milk-BOSATU leak====
On October 11th, 2018, Twitter user Milk-BOSATU (currently named Team NepDon) made a [https://twitter.com/niconico_test_1/status/1050302553118859265 tweet] that claimed that the Hero from Dragon Quest series is a playable character with no female [[alternate costume]]s alongside with VR content for the Switch coming. VR content for the Switch was later revealed as Nintendo Labo VR Kit March 2019 and the Hero was later confirmed to be a DLC fighter in the Fighters Pass Vol. 1 at E3 2019.

====DLC datamines====
On November 28th 2018, a technical data Discord server uncovered ''Ultimate''{{'}}s character parameters table (the list of values such as walk speed and weight) and began decoding it in preparation for the game's release (''Ultimate'' uses {{S|wikipedia|hash function}}s to store strings, so they are not immediately evident and require knowledge and patience to crack). It was found that the first column in the table stored each character's internal development name. It quickly followed that, not only were {{SSBU|Piranha Plant}}'s values already included in the table under "packun" (its Japanese name being Packun Flower), but there was one further slot named "jack". After the 1.1.0 update was made available on December 5th, a second unknown character's attributes were found to have been added, called "brave". Out of respect for players and the game's development team, these discoveries were kept secret.<ref>https://pastebin.com/pEYGazDe</ref>

On January 3rd 2019, the existence of "jack" and "brave" began to quickly spread from an unknown source. With {{SSBU|Joker}} having been revealed, it was assumed that he was "jack" (as "jack" and "joker" are both types of {{s|wikipedia|playing card}}s). "Brave", however, was less clear. The most common speculation was a [[Hero]] from {{uv|Dragon Quest}}; the default class in most games of the series is {{ja|勇者|Yūsha}} (''Yūsha''), which means "Hero" and directly translates to "brave" in English. The parameters of "brave" revealed that their weight is between {{SSBU|Mega Man}} and {{SSBU|Cloud}}/{{SSBU|Mii Swordfighter}}, their running speed is between {{SSBU|Young Link}} and {{SSBU|Kirby}}, and they did not have a neutral infinite, wall jump, or crawl.<ref>https://twitter.com/_Mizumi/status/1080971781790416896</ref> As confirmed upon his release, this data does indeed refer to Hero.

The data for "jack" and "brave" was [https://twitter.com/Meshima_/status/1090492035629346818 removed] from the game data in version {{H2|List of updates (SSBU)|2.0.0}}.

Later, text strings were discovered in the game data that seemingly referred to upcoming DLC. Due to a technical oversight in a particular file format used for ''Ultimate''{{'}}s stage data, unrelated development text leaked into stage data files. The string "Jack_Menentoes_" was [https://twitter.com/DrHyperCake/status/1098341121170665473 discovered], confirming Joker's stage as [[Mementos]] from ''Persona 5''. Another [https://twitter.com/DrHyperCake/status/1098748513251291136 discovery] seemed to imply that one or more of Joker's alternate costumes was an alternate character who has a ponytail hairstyle. However, Joker released with no such costume, implying that the data was scrapped during development.

====Extra game modes datamine====
On March 8, 2019, ''Ultimate''{{'}}s files were [https://www.gamnesia.com/news/rumor-smash-ultimate-is-getting-home-run-contest-and-a-stage-builder datamined], revealing two files named "howtoplay_stage_builder.html" and "howtoplay_homerun.html". The intended purpose of these files is unknown, but it has led fans to speculate that [[Stage Builder]] and [[Home-Run Contest]] are returning to ''Ultimate'' in a future update, with "howtoplay" signifying that the files are for a menu that pops up when the player first selects the modes.

A leak in an advert by Nintendo would later reveal that a Stage Builder was in fact being developed, and it was officially revealed on April 16, set to be released the following day. Home-Run Contest would later be confirmed and released on September 4th with the version 5.0.0 update.

{{clrr}}

====Joker Render leak====
[[File:JokerBestBuyLeak.png|thumb|right|The ad that Best Buy showcased]]
[[File:JokerBestBuyLeakUlti.png|thumb|right|A full image of the page containing the leaked image.]]
On March 31, 2019, Best Buy [https://web.archive.org/web/20190331082404/https://deals.bestbuy.com/?category=video+games3 published] a weekly ad about the Fighters Pass Vol. 1 featuring a render of {{SSBU|Joker}}, creating speculation that Joker's release date and/or gameplay reveal would be at or around the first week of April.

On April 1, 2019, the page was edited to replace the ad for ''Ultimate'' with a fast store pickup ad, thus removing Joker's render alongside it. This spread further speculation that it was his still unrevealed official artwork for the game.

2 weeks later on April 16, Nintendo of Europe's databases added the image of the full render of Joker. That same date, Nintendo released information through a video that Joker would be released the following day, April 17, and fully confirmed the legitimacy of Joker's render.
 
{{clrr}}

====Stage Builder leak====
[[File:StageBuilderLeak.png|thumb|right|The frame in the trailer that leaked Stage Builder.]]
On April 9th, 2019, Nintendo uploaded an ad related to ''Ultimate''; fans quickly noticed that a mere one second in, a "[[Stage Builder]]" option could be seen under "Games and More" on the menu. This seemed to imply that one of the new modes to be added in the 3.0.0 update was going to be a Stage Builder mode, seen previously in ''Brawl'' and ''Smash 4'', but notably absent in ''Ultimate''. This was further supported by the Nintendo Direct aired on February 13th, 2019, which showcased a blurred out image of what was believed to be Stage Builder. Due to the video not being covered up or deleted like the one that revealed Ganondorf, some have speculated that this was in fact not a leak but an intentional marketing ploy.

Stage Builder would later be officially confirmed in a special presentation video about version 3.0.0 on April 16, 2019.

{{clrr}}

====Banjo & Kazooie leak====
On June 4th, 2019, ResetEra admin shinobi602 made a [https://www.resetera.com/threads/banjo-kazooie-controller-holder-teased-by-exquisite-gaming.120331/page-6#post-21418452 post] a week before E3 2019, stating: 'Been a while since we saw Banjo in anything. Hope we’re in for a smashing good time.' The phrase "have a smashing good time" is notable in that [https://www.youtube.com/watch?v=y6An9hlEk1s ResetEra admins] had used the phrase to tease upcoming ''Super Smash Bros.'' content in the past. ResetEra has strict policies about users posting rumors, and as shinobi602 was an admin, along with his perfect track record regarding leaks, this lead many people to believe that shinobi602 was teasing an upcoming {{uv|Banjo-Kazooie}} reveal at the E3 2019 Nintendo Direct. This leak was eventually supported when {{SSBU|Banjo & Kazooie}} were revealed as a part of the Fighter's Pass for ''Super Smash Bros. Ultimate'' at the E3 2019 Nintendo Direct on June 11th, 2019.

====Hero July release date leak====
On July 16th, 2019, Nintendo uploaded a [https://www.youtube.com/watch?v=ldS_kVFyOAI video] under the name "Fan-Favorites & Newest Releases - July" which showed brief clips of ''Marvel Ultimate Alliance 3: The Black Order'' and ''Fire Emblem: Three Houses'', two upcoming games slated to launch in July, as well as ''Fortnite'', the ninth season of which was currently ongoing, and {{SSBU|Hero}} in ''[[Super Smash Bros. Ultimate]]''. This led many to believe that Hero would launch sometime in July. Nintendo later renamed the video to "Fan-Favorites & Newest Releases - Summer".

On July 30th, Hero was confirmed to release on that day.

====Hero 7-11 poster leak====
[[File:Hero7-11.PNG|thumb|The poster from a Japanese 7-11]]
On July 24th, former Source Gaming member PushDustIn posted an image on Twitter showing off a poster from a 7-11 in Japan. The poster included information on both ''Fire Emblem: Three Houses'' and the {{SSBU|Hero}} in ''[[Super Smash Bros. Ultimate]]''. While it only stated that the Hero would release in the summer, the poster also said it would be taken down on August 4th, leading many to believe that the Hero would be launching sometime before August 4th.
Hero was released on July 30th, five days before the poster was taken down.

{{clrr}}

====Dragon Quest spirit board leak====
On July 26th, 2019, several spirit images from {{uv|Dragon Quest}} were discovered to be uploaded by Nintendo onto the [[Smash World]] spirit database, which included:
*Slime
*King Slime
*Dracky
*Golem
*Cetacea
*Great Sabrecub
*Great Sabrecat
*The group of party members from ''{{s|dragonquestwiki|Dragon Quest XI}}''.
Sometime later, Nintendo took down the images. All of the spirits were later confirmed to be in the game, as a part of the ''Dragon Quest'' [[DLC Spirits (mode)|DLC Spirit Board]].

====Nintendo of Europe 4.0.0 release date leak====
On July 29th, 2019, Nintendo of Europe posted a [https://is2.4chan.org/v/1564388552296.png Tweet] containing a release date for the then-upcoming 4.0.0 update, being July 31st. The Tweet was then taken down, and replaced with a [https://twitter.com/NintendoEurope/status/1155777359007682560 Tweet] which instead stated "within 7 days".

The following day, Hero was confirmed to release on July 30th in North America, the day the presentation for Hero aired. The July 31st release in Europe was due to timezones, in that it would be the 31st when the Hero released.

====Nintendo of Europe site SNK fighter leak====
On September 1st, 2019, a page for the 4th challenger pack in the Fighters Pass was created on Nintendo of Europe's website. Within the page was the mention of a copyright belonging to [[SNK|SNK Corporation]] was found. It was speculated to be borrowed from the [https://www.nintendo.co.uk/DLC/SNK-Heroines-New-Character-MissX-1475673.html DLC pages] for ''{{s|wikipedia|SNK Heroines: Tag Team Frenzy}}'' due to having an identical filesize and an incorrect date. However, after cross-checking with the other fighter pack listings and Nintendo pulling down the page soon after its posting, the SNK copyright was confirmed to be a legitimate mistake. Three days later, [[Terry]] from {{uv|Fatal Fury}} would be confirmed as the SNK character for the Fighters Pass.

====Banjo & Kazooie 7-11 poster leak====
[[File:Banjo&Kazooie7-11.PNG|thumb|The poster from a Japanese 7-11]]
On September 1st, 2019, former Source Gaming member PushDustIn posted an image on Twitter showing off a poster from a 7-11 in Japan. The poster included information on both the remake of ''The Legend of Zelda: Link's Awakening'' and {{SSBU|Banjo & Kazooie}} in ''[[Super Smash Bros. Ultimate]]''. Similar to the Hero 7-11 poster, Banjo & Kazooie's poster said it would be taken down by a certain date (in this case, September 15th, 2019), leading to speculation that Banjo & Kazooie would release sometime before that date, as Hero was released before the date that their poster was supposed to be taken down. Banjo & Kazooie were later confirmed for release on September 4th, eleven days before the poster was taken down.

{{clrr}}

====Spirit Board Event SNK Copyright====
[[File:Spirit-Event-SNK-Copyright.PNG|thumb|The SNK Copyright found in the notification of the next spirit board event.]]
On October 30th, 2019, the [https://www-aaaba-lp1-hac.cdn.nintendo.net/en-US/e432a816/index.html notification] for the Spirit Board Event [[Smash by the Sword]] went live. The event ran between November 1st to 4th. Located at the bottom of the notification is the copyright for the SNK Corporation, which was newly added. This led to rumors that {{SSBU|Terry}}'s release date would be near the beginning of November. This speculation was eventually proven correct with Terry's release on November 6th.

{{clrr}}

====7th Challenger Pack 7-11 poster leak====
[[File:FightersPassVol2_7-11.jpeg|thumb|The poster from a Japanese 7-11]]
On September 20th, 2020, @OunaAlt posted an image on Twitter showing off a poster from a 7-11 in Japan. The poster included information on both second DLC of Pokémon Sword and Shield ''Tundra of Crown'' and Second Fighters Pass Lineup with {{SSBU|Min Min}} and six unannounced Challenger Packs in ''[[Super Smash Bros. Ultimate]]''. On the top right corner of the poster we see an information which poster will expired to 4th October, 2020. This means 7th Challenger Pack will announce before 4th October, 2020.
