Editing Final Smash

{{cquote|The basic gist of it? I suppose you could say it's kind of like a powerful and personalized {{b|hammer|item}}. (Or maybe not...)|cite=[[Masahiro Sakurai]], [http://www.smashbros.com/wii/en_us/howto/basic/basic02.html Smash Bros. DOJO!!]}}

To perform a Final Smash, a player must first either destroy a [[Smash Ball]], fill the [[Final Smash Meter]] in ''[[Super Smash Bros. Ultimate]]'' (although then the Final Smash will be weaker), be given the ability by [[Victini]] or fall sufficiently far behind in a match that they are given a "Pity Final Smash" upon respawning. Once any of these happen, the screen will darken, the player's [[character]] will be engulfed in a multi-colored aura and their eyes will glow a bright yellow; officially referred to as '''Standby Mode''', the character's [[neutral special move]] is effectively replaced with a single use of their Final Smash.

In ''Brawl'', the majority of Final Smashes are powerful enough that they have the potential to KO incredibly early or even [[one-hit KO]] if used properly. In ''[[Super Smash Bros. 4]]'', Final Smashes were universally made much weaker, many of them no longer being able to KO opponents at low percentages. [[#Changes in Ultimate|In]] ''[[Super Smash Bros. Ultimate]]'', they have been slightly nerfed overall once again. If a player doesn't use a Final Smash granted by the Final Smash Meter in about 20 seconds, the effect will expire. Final Smashes have also been tweaked to be less disruptive to the gameplay.

While multiple players can be in standby mode simultaneously, only one Smash Ball or Final Smash can be present onscreen at any given time. When a Final Smash is active, all other players on standby temporarily exit standby mode and regain it upon conclusion, although they will keep the yellow eyes. When most Final Smashes are performed in the air, upon ending the move, the character gains a slight boost in height and regains their spent midair jumps, usually preventing a self-destruct.

Final Smashes are affected by [[Rage]] and [[stale-move negation]] (and therefore will usually gain a freshness bonus) along with [[spirit]]s, but are not affected by stat changes from equipment or Mii Fighter sizes in ''Smash 4''.

[[Masahiro Sakurai]] revealed in an interview with former Nintendo president [[Satoru Iwata]] that he intended to include Final Smashes in the original ''[[Super Smash Bros.]]'', even going as far as to record [[Beta elements (SSB)#Beta gameplay elements|voice clips]] for each of them.<ref>https://iwataasks.nintendo.com/interviews/#/wii/ssbb/4/0</ref> However, the [[Nintendo 64]]'s console limitations could've been the reason why they were scrapped and the idea wouldn't be implemented until ''Brawl''. Some of these voice clips, which were contained in the ''Super Smash Bros.'' {{SSB|debug menu}}, were eventually and correspondingly used in ''Brawl''.

[[File:Pity.jpg|thumb|Link with a Pity Final Smash.]]

A '''Pity Final Smash''' ('''Easy Final Smash''' in ''SSB4'' and ''Ultimate'') randomly occurs when any player is KO'd and is 5 points behind the current leader. Also, in ''SSB4'', at least 6 KOs between all players must be landed for any player to acquire one. This player respawns with the ability to perform a Final Smash. This Final Smash cannot be dropped by the player.

In a 2-player [[time]]d match in ''Brawl'', since the points differ by two for each kill, it is possible to go from a lead of 4 points to 6 without triggering the Pity Final Smash condition (which is to be exactly 5 points behind). If a player SD's, and consequently loses only one point, then a Pity Final Smash is possible.

Pity/Easy Final Smashes cannot occur while a [[Smash Ball]] is present on the battlefield, even when the requirements are met. In ''Brawl'', Pity Final Smashes can be disabled only by turning the Smash Ball off; simply setting the overall [[item]] frequency to "None" does not prevent players from getting them. In ''SSB4'', either method will prevent Easy Final Smashes. Additionally, they cannot occur in 2 player matches, for AI players, or by a player SD'ing.

Sakurai stated in a Nintendo Direct that every Final Smash would be standardized to be simple and straight to the point. As a result, Final Smashes were made universally faster in ''Ultimate'', removing most player-controlled ones; the KO potential of Final Smashes has also been reduced. Because of the universal speed increase and control removal applied to Final Smashes, many Final Smashes such as Bowser's Giga Bowser, Wario's Wario-Man, and Little Mac's Giga Mac had their functionality changed significantly (they no longer use their full moveset transformation Final Smash; it is instead a single hit that quickly returns to regular gameplay). Others such as Fox and Falco's Landmaster and Donkey Kong's Konga Beat, have been completely replaced. The [[Final Smash Meter]] (FS Meter) is also introduced, which is a toggle feature in the [[rules]] that allows players to gain a weaker form of their Final Smash by filling up their gauge during battle. However, while multiple meters can be full at once, only one Final Smash can be performed at a time. All other FS Meters are disabled while a Final Smash is active, then re-enabled once it concludes. As of update version 4.0.0, players can hold onto a full FS Meter for up to 20 seconds before losing it and starting over. In addition, when Victini appears, it will give the fighter who summoned it access to their Final Smash without filling up their meter.

* Several Final Smashes are disproportionately powerful; were Final Smashes to be allowed, certain characters would become overcentralizing picks due to their Final Smash alone.

** Compared to other chargeable attacks such as [[Wario Waft]], [[KO Uppercut]], or [[Finishing Touch]], as well as similar super move mechanics in other fighting games, Final Smashes are [[unblockable]], make the user fully [[intangible]], and have no associated high-risk downside.

*There are five Final Smashes that can affect a team player when [[Team Attack|Friendly Fire]] is turned off: [[End of Day]], [[Landmaster]], [[Puff Up]], [[Iceberg]], and [[Galaxia Darkness]] (in ''Brawl'' only).

*[[Ryu]] and [[Ken]] are the only fighters with two distinct Final Smashes in a single installment. [[Cloud]] also received a new Final Smash for his ''Advent Children'' costumes in version 10.1.0 in ''Ultimate'', but it is mostly an aesthetic change to his default one.

*The input [[Hadoken]], Shakunetsu Hadoken, and Oosoto Mawashi Geri can still be performed while in Final Smash standby mode.

**[[Magic|Firaga]] can also be repeatedly used while in Final Smash standby mode if it was the move used to break the Smash Ball, and [[Monado Arts]] can also be used in Final Smash standby mode, albeit only through the Art Dial by holding the special button while ending another special move. This makes Ryu, Ken, Shulk, and Sora (and Kirby with their Copy Abilities) the only fighters who can use a neutral special move in standby after breaking the [[Smash Ball]], barring [[Golden Glitch|glitches]] and disc load delay.

*Mario, Captain Falcon, and Jigglypuff are the only three characters in the Original 12 to have kept their Final Smashes the same from ''Brawl'' in both ''Smash 4'' and ''Ultimate'' without any functionality changes.

**This therefore makes Mario the only character part of the original 8 to not have his Final Smash change in function.

*[[Pit]], [[Zero Suit Samus]], [[R.O.B.]], and [[King Dedede]] are the only characters to have a different Final Smash in every installment since their introduction, with a total of three each.

**Of these, All-Out Attack, Gigaslash, House of Boom, and Supernova are the only Final Smashes to remove it for the entire duration of the move.

*In ''Ultimate'', when a character uses their Final Smash and another character is in the frame during the initial shot, the other character will have a shocked expression on their face.

*In [[Spirits (mode)|Spirit Battles]], after a puppet fighter with a permanent gold [[condition]] uses a Final Smash, they will return to normal before having the golden effect reapplied to them, playing the power-up sound and creating glowing particles just like when a fighter turns to gold when they collect 100 coins in [[Golden Plains]] or summon [[Xerneas]] from a [[Poké Ball]].

*In ''Ultimate'', there are noticeably many characters whose Final Smash (or new Final Smash, in the case of veterans) wasn't officially announced until the game's initial release. This includes, {{SSBU|Young Link}}, {{SSBU|Meta Knight}}, {{SSBU|Diddy Kong}}, {{SSBU|Lucario}}, {{SSBU|R.O.B.}}, {{SSBU|Robin}}, {{SSBU|Daisy}}, and {{SSBU|Richter}}. While {{SSBU|Rosalina & Luma}}'s Final Smash was shown in their gameplay showcase video, it used the {{iw|mariowiki|Power Star}} like in ''Smash 4'', instead of the {{iw|mariowiki|Grand Star}} from the final build.

**If the game is played via local wireless or online and the Switch home menu is booted up, the Final Smash will still continue to play out until the end.

*Wario, Joker, {{SSBU|Steve}}, and {{SSBU|Sora}} are the only characters with a cinematic Final Smash who break the fourth wall by facing the screen during the cinematic in ''Ultimate''.
