Editing Sonic (SSBU)

'''Sonic''' ({{ja|ソニック|Sonikku}}, ''Sonic'') is a playable character in ''[[Super Smash Bros. Ultimate]]''. He was confirmed as a playable character on June 12th, 2018. As in ''[[Super Smash Bros. Brawl]]'', he is [[unlockable character|unlockable]], instead of being available from the [[starter character|start]]. Sonic is classified as [[Fighter number|Fighter #38]].

As in ''Smash 4'', Sonic's voice clips from the Japanese version of ''Brawl'', the English versions of ''Sonic Generations'', ''Sonic & All-Stars Racing Transformed'', and ''{{s|mariowiki|Mario & Sonic at the London 2012 Olympic Games}}'', and the French, Italian, German, and Spanish versions of ''Sonic Generations'' and ''Mario & Sonic at the Sochi 2014 Olympic Winter Games'' were repurposed for ''Ultimate''.

*Jonatán López in Spanish, in place of his current Spanish voice actor Ángel De Gracia. This was the former's last game as Sonic's Spanish voice actor before he passed away in February 2020.

Sonic is a [[weight|lightweight]] who, staying true to his home series, has outstanding mobility. He unsurprisingly possesses the fastest [[dash]]ing speed in the game by default (surpassed only by {{SSBU|Hero}} under the effects of [[Command Selection|Acceleratle]]), the 7th fastest [[walk]]ing speed, the 12th fastest [[air speed]] (tied with {{SSBU|Mario}}, {{SSBU|Donkey Kong}}, {{SSBU|Little Mac}}, and {{SSBU|Inkling}}), and the highest [[traction]] in the game (surpassed only by {{SSBU|Sephiroth}} under the effects of [[Winged Form]]). When combined with his above average [[falling speed]] and jumps, this allows him to move across the stage at the speed of quick, despite having average [[gravity]] and slow [[air acceleration]]. As a cherry on top, he can even [[wall jump]].

Sonic's special moves are quite useful. [[Spin Dash]] and [[Spin Charge]] allow him to not only move across stages at varying speeds, but also do damage on contact, and both can follow up into an aerial attack or uncharged Homing Attack. Despite their very similar-looking appearances in functions, they both have different strengths and uses for various different situations.

Spin Dash allows Sonic to jump around the stage while charging or holding the charge of the move and can be released in the air, and the hop at the start of the move allows Sonic to "spinshot" on ground as well as in the air, with it being the side special making it more ideal for aiming the spin shot to recover. The initial jump can also help Sonic avoid certain things like projectiles by hopping over them, it, however, loses this initial hop if fully charged. Spin Dash also has a moment of intangibility on startup, which can bypass even Wonderwing. The intangible fully charged version can pass through most grounded attacks but will clank with projectiles and aerial attacks. The non-fully-charged version with the hop though can bypass if not beat out almost anything due to being aerial. The fully-charged version of Spindash will also be intangible whenever Sonic turns the move around. Due to the number of branching choices Sonic has when starting Spin Dash, it is his most reliable attack in neutral and one of his best approach options overall. From jumping into cancellation, charging it to alter its timing, switching directions after releasing, and utilizing the spin shot, Spin Dash plays an extremely important role when attempting to play mind games versus Sonic's opponent.

While Spin Dash is a one-hit move that mostly knocks opponents into the air, Spin Charge, on the other hand, hits multiple times, carrying the opponent, and moves a little faster, making it a good alternative for dashing. Jumping out of Spin Charge also has Sonic hop while spinning, making him a jumping hitbox. Also, due to charging up by pushing the Special Move button repeatedly, it can be charged up to full power faster than Spin Dash. Spin Charge can also perform a "spinshot", although it can only be done while airborne and can't be reversed.

Both give Sonic additional protection when recovering and combo into other moves. The mobility of both in tandem with Sonic's already impressive speed makes him capable of quickly adding on damage to unprepared opponents from anywhere on the stage, and they can clank and cancel out the effects of certain moves, such as Snake's [[C4]] or Yoshi's Egg Roll. Both moves can be blocked by shield, making them a bit unsafe and committal or predictable, as Spin Dash can only be canceled with a jump and Spin Charge can only be canceled by jumping or stopping pressing the Special Move button. However, they can bypass shields if fully-charged and jump over them on initial contact.

[[Homing Attack]] deals a varying amount of damage, homes in on the nearest opponent and is good for punishing laggy moves and [[edge-guard breaking]]. Its uncharged state also has the potential to combo and its charged state has a small amount of KO potential at higher percents. [[Spring Jump]] is a useful recovery that grants intangibility at the start, goes very high, and is one of few recovery moves that do not cause a [[helpless]] state, enabling Sonic to attack and dodge during his descent and even extend his recovery with a directional air dodge. The spring that is dropped can be useful both on-stage and off-stage by allowing him to pressure and [[gimp]] opponents, respectively.

Sonic also has a powerful air game. Neutral aerial is a great combo starter when [[SHFF]]'d, as a result of its long-lasting hitbox, low landing lag, and launching angle. Forward aerial is useful for [[edgeguarding]] and, in certain instances, it can combo into itself on-stage at low percentages, thanks to its generous [[auto-cancel]] window and Sonic's fast air speed. Up aerial possesses KO potential near the upper [[blast line]] and is great for combos, while its auto-canceling window makes it deceptively safe. Back aerial's clean hitbox is very powerful, making it one of his few reliable kill moves like his up aerial, and coupled with its strength within Sonic's kit, also makes it his best aerial finisher. Lastly, down aerial is a [[stall-then-fall]]; although it is Sonic's least effective aerial, it has noticeably less ending lag compared to other stall-then-falls, and its initial hitbox [[meteor smash]]es aerial opponents, allowing him to meteor smash an opponent near the edge of the stage and still be able to recover, even if he misses.

Sonic's neutral attack, tilts, and throws have decent damage outputs and good speed, making them hard to [[punish]]. His grab game is decent overall: While none of Sonic's grabs excel in speed and each of them has average ranges, they are still fairly easy to land thanks to his outstanding speed. Sonic's [[pummel]] is also quick and has an average damage output, allowing him to rack up a fair amount of damage before throwing an opponent. Down throw is a [[semi-spike]] that has high base knockback, which makes it excellent for setting up edge-guards and [[tech-chase]]s. Back throw also has high base knockback and KOs much earlier than his other throws, especially if it is used while near the edge. It also moves Sonic backward, which makes it useful for setting up an immediate edge-guard attempt. Up tilt can be reversed on startup and hit opponents through platforms above Sonic, and his Forward Smash has a bit of a deceptively large range due to him stepping forward during the punch.

Up throw is a reliable combo starter, having decently damaging combos beginning at 0%, as well as Spring Jump-assisted aerial combos beginning at medium percentages. It also has KO potential, although it only KOs reliably at very high percentages when used on high platforms, such as {{SSBU|Battlefield}}'s top platform, as well as stages with low upper blast zones. Lastly, forward throw is his least useful throw, as its primary utility is for forcing the opponent away from him. Like up throw, it can also function as a KOing option, albeit only when used on the edge at very high percentages.

Mastering Sonic's running game is crucial to Sonic's ability to perform at higher levels. Sonic users take advantage of a variety of dash or dash-related techniques that are seldom used by other characters. Dash-dancing can be extremely useful for mind games in Sonic's gameplay, such as by running in one direction and then quickly turning the other way around to bait an opponent or catch them off-guard. It is often regarded by Sonic players that it is better to run away from the opponent and run back than to use roll-dodges to avoid opponents. This allows the player to avoid damage, not be as easily punished, have more control over their actions, and be able to punish their opponent's attacks. Dash-dance pivots (consisting of fox-trotting away from the opponent, then quickly dash-dancing backward) are particularly effective for this, as they can cause almost immediate turnarounds and then grabs can then be used to punish opponents. In general, Sonic has the easiest time winning neutral exchanges due to his unmatched speed and maneuverability on-stage, and attacks that not only come out fast but can also be used to approach with.

Sonic has some weaknesses however, the most noticeable being his KO potential. It is held back by his best kill moves (his smash attacks and clean back aerial) requiring good positioning and having noticeable startup and ending lag. His forward and up smashes are also burdened with low base knockback, which forces them to be used for KO attempts later instead of earlier, and his down smash, although it has decent startup, has high ending lag, making it easy to punish if missed. While Sonic’s damage-racking ability is formidable, his actual ability to take stocks is among the worst in the game, which oftentimes results in his opponents surviving beyond 150% and even 200%. Despite his outstanding mobility, Sonic may struggle to land due to his very slow air acceleration, leaving him susceptible to [[juggling]].

Sonic can also have difficulty dealing with [[camping]], since any ground-level [[projectile]] can severely limit his movement options. While Homing Attack and Spin Dash are his best options in getting through said projectiles, they can be reacted to and even predicted. Some of his attacks are also very punishable should they miss, and thus allow openings for opponents to punish him. Homing Attack can miss if his opponent is moving too fast or is in the middle of an attack when Sonic releases the move. His recovery is also predictable with Spring Jump as his only vertical recovery option, as its linearity makes him susceptible to gimps even at relatively low percentages. Finally, Sonic can be susceptible to early KOs due to being a lightweight.

Much like in ''Brawl'', Sonic's matchups are difficult to define, as they vary greatly from player to player, possibly more so than for any other character. Depending on the playstyle of the Sonic, he can have a decent matchup against almost any character in the game, even at competitive levels. Because of his prowess for mindgaming and switching up tactics, as well as the inherent strengths and weaknesses of each style of play, some Sonic mains argue that he has no truly disadvantageous matchups as a character and that his matchups are much more heavily influenced by playstyle than his actual attributes.

In all, Sonic has a great offensive play, a strong [[neutral game]], a good off-stage presence, and can very rapidly damage his opponents, but like other characters of his archetype, has some trouble killing.

Like most other top-tier characters, Sonic was often regarded as one of the most potent characters in ''Smash 4'', which was reflected in its latest tier list (tied with Fox for 7th out of 55th). His phenomenal ground movement and [[Spin Dash]] not only granted him a powerful [[neutral game]], but also encouraged a borderline oppressive hit-and-run playstyle, to a point where Sonic players would often utilize [[time out]] strategies after having a stock/percentage lead to win games. Likely as a result of this, Sonic was given a mix of buffs and nerfs in his transition to ''Ultimate'', but was nerfed overall.

Several of Sonic's key strengths and moves from ''SSB4'' have been toned down considerably. Arguably his biggest nerf was towards his Spin Dash: it can no longer be shield canceled and can no longer go through shields unless it is fully charged; this noticeably hinders Sonic's infamous camping ability and mindgames from ''Smash 4'', and it also forces Sonic to rely more on his pure speed to play defensively. [[Up aerial]], known for its status as a strong KO option off of moves like [[Spring Jump]] and Spin Dash, has received angle and knockback adjustments to the first hit that worsen its ability to connect into the second hit as reliably, no longer managing to follow Sonic's momentum when he jumps and hindering its effectiveness and consistency for combos. This is further compounded by [[up throw]]'s nerf; known for being a potential finisher due to its ability to combo into Spring Jump-assisted setups, it now has increased endlag, effectively removing most of Sonic's Spring Jump-assisted combos off of it. Lastly, Spring Jump's spring now sends opponents at a more horizontal angle, toning down its edge-guarding potency, and has much less intangibility frames, making it easier to intercept Sonic during his recovery. His much lighter weight and increased falling speed also worsen his disadvantage state, making him easier to combo and KO if the opponent is able to catch him.

However, Sonic has been granted notable buffs as well, particularly towards his less impressive attacks. In particular, [[Homing Attack]] has been buffed significantly: it has faster startup, less endlag upon hitting an opponent, better accuracy, and the ability to be charged for longer; this has lead to the move becoming a much more viable combo tool as well as a potential option in the neutral game. His [[down tilt]] launches opponents at a higher angle now, granting it combo potential. All of his smash attacks were improved, with [[forward smash]] gaining more range, and [[up smash|up]] and [[down smash]] having better KO potential. Additionally, some of Sonic's better moves have been buffed in various ways. Despite having been worsened overall, Spin Dash now has the ability to be jump canceled, alleviating some of Sonic's potential mix-up options, albeit they remain less effective than previously. Spring Jump now grants Sonic slightly more distance, buffing his already impressive recovery. Several of Sonic multi-hitting attacks (sans up aerial) now link into each other more reliably, including [[Spin Charge]], up smash, [[forward aerial]], and [[forward tilt]].

Sonic also benefits incredibly from ''Ultimate's'' universal mechanic changes. Known for having high landing lag on his attacks in ''Smash 4'', Sonic now possesses much less landing lag on all of his aerials, although still above average relative to the cast; this grants neutral aerial increased combo potential, improves back aerial's safety as a spacing option, and makes down aerial a slightly safer (albeit still unsafe) landing option. Sonic's already unmatched ground mobility has been improved even further, with his initial dash now being among the fastest in the game, heightening his camping abilities via simply running away. The ability to [[run cancel|use any attack out of a run]] allows Sonic to take advantage of his phenomenal ground movement more than most other characters in ''Ultimate'', granting him powerful mix-up options he previously didn't have access to. Finally, the changes to [[air dodge]] mechanics improve Sonic's edgeguarding game while not compromising him much thanks to his great recovery, while the reintroduction of directional air dodges allows Sonic to gain a little extra distance after using Spring Jump.

Overall, while Sonic still retains his powerful attributes and combo game, several of Sonic's most powerful tools from ''SSB4'' have either been worsened or have been removed altogether. This has lead to a generally less effective character than in ''SSB4'', as Sonic is now forced to make greater use of his standard moveset instead of relying on Spin Dash and Spin Charge to compensate for his underwhelming attacks, and must now take advantage of ''Ultimate's'' reworked mechanics and gear towards a more creative and offensive playstyle than in ''SSB4''. Regardless, although Sonic initially had a below-average perception, it has become more positive over time, with smashers like {{Sm|KEN}}, {{Sm|Sonix}}, {{sm|Sonido}} and {{Sm|Wrath}} achieving some solid results in tournament play, albeit not to the same degree as in ''SSB4''. In the end, in spite of his initial mediocre perception, Sonic remains a viable, high tier character in competitive play once mastered, and as a result, he is one of the few ''SSB4'' top tier veterans to keep placing well in tournament play in ''Ultimate'', alongside {{SSBU|Mario}}, {{SSBU|Fox}}, {{SSBU|Zero Suit Samus}}, and {{SSBU|Cloud}}.

Aside from glitch fixes, Sonic has been buffed via game updates. While [[Super Sonic]] has been buffed in a few ways through various updates, a number of Sonic's other moves have also received noticeable improvements. Update 2.0.0 improved forward tilt's consistency and decreased back aerial's landing lag, while update 3.0.0 ensured that Sonic retains his double jump upon using [[Spin Dash]] or [[Spin Charge]] on a platform. Update 7.0.0 enlarged his shield as part of a near-universal buff, and significantly improved up smash's reliability against an opponent standing on a platform, the latter of which was shared with {{SSBU|Roy}} and {{SSBU|Chrom}}'s up smashes.  

However, update 9.0.0 brought about Sonic's most significant buffs. Both up tilt and dash attack had their ending lag decreased, with the latter's poor damage output also being increased. As a result, both moves are safer on shield. Up smash's overall lag was decreased, it gained more intangibility, and its first hit's angle and knockback were adjusted; altogether, these changes improved its consistency and safety. Lastly, up aerial's second hit received another hitbox below Sonic, which improved the move's somewhat infamous inconsistency.

*Sonic continuously receives damage while [[swimming]]. This trait is shared with {{SSBU|Charizard}}, {{SSBU|Inkling}}, and {{SSBU|Incineroar}}. This is a reference to the classic ''Sonic the Hedgehog'' games where Sonic is unable to swim and needs to constantly collect air bubbles or else he would drown and die instantly.

|neutraldesc=The Punch + Punch + Kick combo from ''Sonic the Fighters''. Its first and second hit are capable of [[jab lock]]ing. Holding the attack button will have Sonic perform the first hit repeatedly.

|ftiltdesc=The Horse Kick from ''Sonic the Fighters''. It hits twice, has minimal start-up lag, and can be angled. Altogether, these traits make it useful for spacing, starting [[tech-chase]]s, and as an [[out of shield]] option.

|utiltdesc=A {{s|wikipedia|540 kick}}, similar to {{SSBU|Captain Falcon}}'s up smash. Its decent vertical range makes it a fairly useful anti-air attack, although it has poor horizontal range. It resembles the Skip Kick from ''Sonic the Fighters''.

|dtiltdesc=A legsweep. Unlike in ''SSB4'', it launches opponents diagonally, which enables it to start combos at lower percentages. It resembles the Leg Throw from ''Sonic the Fighters'', and the Foot Sweep from ''Sonic the Hedgehog'' (2006) and ''Sonic Unleashed''.

|dashdesc=A flying kick. A decent follow-up from a down throw, although this requires a read. While its very minimal start-up lag can allow it to pressure unwary opponents, it is quite punishable thanks to its considerable ending lag.

|fsmashdesc=The Wind-Up Punch from ''Sonic the Fighters''. It has high knockback growth and deceptive range, and it can be angled. Altogether, these traits make it one of Sonic's best KO moves, if not his absolute best one. However, it has low base knockback, and thus should be used for KO attempts later instead of earlier. It also has noticeable start-up and ending lag, making it risky if used unwisely.

|usmashdesc=A jumping Spin Dash. It has moderate start-up and noticeable ending lag, making it risky if used unwisely. It hits multiple times, with the last hit having extremely high knockback scaling but merely average base knockback. As a result, it should be used for KO attempts later instead of earlier. It is also excellent at shield poking, thanks to its somewhat large hitboxes.

|dsmashdesc=A split kick, similar to {{SSBU|Fox}} and {{SSBU|Falco}}'s down smashes. It has the lowest amount of start-up lag out of Sonic's smash attacks and hits on both sides, which make it useful for punishing rolls. It is also a [[semi-spike]], which makes it very useful for edge-guarding. However, it lasts for only 2 frames and, like his other smash attacks, has considerable ending lag.

|nairdesc=The Air Spin from ''Sonic the Fighters''. In addition to being a reliable follow-up from [[Spin Dash]], [[Spin Charge]], and [[Spring Jump]]-assisted combos, its launch angle makes its clean and late hitboxes useful combo starters at low to medium percentages when [[SHFF]]'d.

|fairdesc=A corkscrew [[wikipedia:Professional wrestling attacks#Battering ram|battering ram]], similar to {{SSBU|Pikachu}}'s forward aerial. It is tied with up aerial for the lowest amount of start-up lag out of Sonic's aerials. When coupled with the last hit's very high knockback growth, it is quite useful for spacing and edge-guarding. It can also combo into itself in certain instances, thanks to Sonic's very fast air speed and the move's fairly large [[auto-cancel]] window. It resembles the Emerald Dive from ''Sonic the Fighters''.

|bairdesc=A hook kick. Its clean hitbox's impressive damage output and high knockback growth make it one of Sonic's best KO moves, especially while edge-guarding. The move is also one of the more powerful of its type when hit clean. However, it does have moderately high start-up lag, making it somewhat tough to land.

|uairdesc=A scissor kick. Its very large auto-cancel window and fairly low landing lag make it deceptively safe. In addition to being a reliable follow-up from Spin Dash and Spin Charge, it is a useful combo starter when SHFF'd. Due to its first hit's adjusted launching angles and its second hit's much lower knockback growth, it is noticeably less effective than it was in ''SSB4'' as a follow-up from Spring Jump and as a KO option.

|dairdesc=A diagonal flying kick. It is a [[stall-then-fall]], but unlike the majority of other stall-then-falls, it is relatively safe to use off-stage thanks to its noticeably lower ending lag in comparison. Its clean hit also [[meteor smash]]es aerial opponents at the beginning of the attack, but not grounded opponents. It resembles the Stomp Dive from ''Sonic the Fighters'' and the Sonic Rocket from ''Sonic Battle''.

|pummeldesc=A knee strike. A fairly fast pummel.

|fthrowdesc=A stretch kick. Due to its launching angle and overall knockback being noticeably lower than in ''SSB4'', it now functions as a serviceable edge-guard set-up at the very negligible cost of its almost nonexistent KO potential. It resembles the Top Kick from ''Sonic Battle''.

|uthrowdesc=Heaves the opponent overhead and then stabs them with his quills to launch them upwards. It can be followed up with a neutral aerial, up aerial and inputted [[Homing Attack]] at low percentages. Due to its ending lag being increased since ''SSB4'', its Spring Jump-assisted follow-ups less consistent. It also has KO potential, albeit only at very high percentages and when used on highly positioned platforms, such as Battlefield's top platform.

|dthrowdesc=Pins the opponent to the ground and then Spin Dashes onto them. Due to being a semi-spike, it is reliable for tech-chasing and setting up edge-guards. It resembles the Double Spin from ''Sonic the Fighters''.

|nsdesc=Curls up into a ball while briefly ascending, homes onto the nearest opponent, and then rams into them. Pressing the special button will execute the move earlier, albeit dealing less damage. It can be used as a follow-up combo from various moves if executed early.

|ssdesc=Curls up into a ball, performs a short jump, and then starts rolling toward the opponent at a fast speed. Holding the special button [[charge]]s it up and increases its speed. In addition to granting intangibility at the start, it boasts impressive combo potential, thanks to its ability to be followed up with any aerial attack. However, if uncharged, it stops when it hits a shield, making it very unsafe if shielded. It also boasts horizontal recovery potential when it is [[jump-cancel]]ed immediately upon releasing the special button; this turns the dash into a "Spin Shot", a quick, long-ranged short hop that can be performed either on the ground or in the air.

|usdesc=Sonic is sent upwards by a spring. When used on the ground, it remains in place for a few seconds, allowing Sonic and any other character to keep bouncing off of it until it vanishes. Although this move is primarily used for recovering, it is also useful for partaking in combos. It grants intangibility at the start, while the spring itself can also be used to [[gimp]] recovering opponents underneath Sonic.

|dsdmg=1.5%-2.3% (loop), 4% (last), 6% (jump)

|dsdesc=A Spin Dash that hits multiple times and has more momentum. It also has slightly different aesthetics compared to Spin Dash, and requires button mashing in order to charge. However, it lacks a short jump at its beginning, cannot be canceled in any way, and it can only become a "Spin Shot" when used in the air.

*'''Up:''' Runs up to the camera and grabs the blue [[Chaos Emerald]], then poses with it. His Japanese line comes from ''Sonic Heroes'' after activating the final switch of Mystic Mansion.

*'''Right:''' Performs the [[wikipedia:Kick (b-boy move)#Variants|pike]], Foot Sweep and backflip from [[wikipedia:Sonic the Hedgehog (2006 video game)|''Sonic the Hedgehog'' (2006)]], then strikes a pose. His Japanese line comes from ''Sonic Adventure'' after defeating a boss.  

Sonic victory quotes in each language are:

==In competitive play==

 

However, he retained his superb mobility, long-distanced recovery, and combo game, along with a marginal improvement to several moves' KO potential. The character has amassed notoriety for his hit-and-run playstyle, allowing multiple top players to resort to [[time out]] strategies due to the difficulty of intercepting him. As a result of capitalizing on these strengths, Sonic saw a rise in results across the Fall 2019 PGRU season, having notable placements in majors such as Frostbite 2020 and EVO Japan 2020, courtesy of players like Sonido, Wrath, and KEN. When patch 9.0.0 was released, Sonic was given more buffs, most notably his Up Aerial, which can connect more reliably and consistently, giving Sonic more combo potential. His other moves have less end lag and startup, making his approach options safer. As his results have continued to mount in the post-pandemic environment, the general perception of him has become significantly favorable, with many professional players arguing that he's a solid or upper high tier at minimum, and several thinking he's a top tier.

 

Within the online meta, Sonic is commonly considered one of the game's strongest characters and has seen exemplary tournament performance. The online environment of ''Ultimate'' arguably benefits Sonic more than any other character due to increased input lag, rendering it harder to contend with Sonic's campy playstyle and intercepting his already powerful burst options. Due to the [[COVID-19 pandemic and its impact on competitive Smash|COVID-19 pandemic]] forcing competitive events to be held online throughout 2020, this has caused a controversial perception of Sonic in competitive play, as many players have been critical of how effective his playstyle and ability to time players out are, with some even going so far as saying he should be banned. While the general consensus has been that Sonic is not worthy of a ban, many have argued for stricter rules in terms of camping and timing players out. Sonic's competitive results around this time were also partially bolstered by non-US players and Wi-Fi warriors such as {{Sm|Sonix}} being able to compete in more tournaments, who is currently ranked fourth in the [[Wi-Fi Warrior Rank v6]].

|1||{{CharHead|Fox|SSBU|hsize=20px}}||[[Green Hill Zone]]||''{{SSBUMusicLink|Sonic The Hedgehog|Green Hill Zone}}''||Fox represents Sonic’s sidekick, [[Miles "Tails" Prower]].

|2||{{CharHead|Captain Falcon|SSBU|hsize=20px}}||[[Figure-8 Circuit]]||''{{SSBUMusicLink|Sonic The Hedgehog|Super Sonic Racing}}''||The stage, music, and opponent all reference ''Sonic R'', a racing game.

|3||Giant Metal {{Head|Sonic|g=SSBU|s=20px}} Sonic||[[Fourside]] ([[Ω form]])||''{{SSBUMusicLink|Sonic The Hedgehog|Open Your Heart}}''||''Open Your Heart'' being played during the battle and the city setting likely reference the boss battles against Chaos in ''Sonic Adventure'', particularly the one against Chaos 0; the stage and opponent could also reference the Metal Sonic boss fight at the end of Stardust Speedway Zone in ''Sonic CD''. Although the costume is revealed to be the default costume, the CPU will always have the default costume regardless of what costume the player is using.

|4||{{Head|Kirby|g=SSBU|s=20px|cl=Yellow}}{{Head|Kirby|g=SSBU|s=20px|cl=Blue}}{{Head|Kirby|g=SSBU|s=20px|cl=Red}} {{SSBU|Kirby}} (x3)||[[Halberd]]||''{{SSBUMusicLink|Sonic The Hedgehog|Sonic Heroes}}''||The Kirbys represent the three character types from ''Sonic Heroes'': Speed (Blue), Flight (Yellow), and Power (Red). The stage choice likely references Final Fortress, the final level of said game.

|5||{{CharHead|Sheik|SSBU|hsize=20px}}||[[Mushroomy Kingdom]]||''{{SSBUMusicLink|Sonic The Hedgehog|Seven Rings in Hand}}''||The stage, music, and opponent all reference ''Sonic and the Secret Rings'', which has an Arabian setting.

|6||Giant {{CharHead|Incineroar|SSBU|hsize=20px}}||[[Windy Hill Zone]]||''{{SSBUMusicLink|Sonic The Hedgehog|Wonder World}}''||Incineroar represents Zavok, the leader of The Deadly Six, who debuted in ''Sonic Lost World''.

During the opening cutscene, Sonic was present on the cliffside when [[Galeem]] unleashed his beams of light. While attempting to run away, Sonic noticed {{SSBU|Pikachu}} doing the same and reached his hand towards Pikachu in an attempt to save it. However, he and Pikachu were vaporized and placed under Galeem's imprisonment.

Sonic was one of the many fighters that fell under [[Dharkon]]'s control upon Galeem's first defeat. He appears in the [[Sacred Land]] sub-area as one of the fighters that block the [[Master Sword]], making him one of the obligatory unlocks. His location could potentially be a reference to ''Sonic & the Black Knight'' and/or the ''Zelda''-themed level in ''Sonic Lost World''.

He is later seen standing next to {{SSBU|Mario}}, as the heroes prepare their last stand against Galeem and Dharkon.

*One of the [[List of tips (SSBU)#Sonic|in-game tips for Sonic]] states that using his down aerial after a jump and Spring Jump in succession can allow for "no landing delay". However, this is incorrect, as Spring Jump actually incurs 10 frames of landing lag, which persist even if Sonic auto-cancels his down aerial by using it from high enough as stated by the tip.

***It could, however, mean that no landing lag persists from the aerial move itself, and only occurs from Spring Jump, which was possibly added due to the universal landing lag reductions in ''Ultimate''.

*Sonic's stock icon in ''Ultimate'' bears a striking resemblance to several logos and icons in the ''{{uv|Sonic}}'' series, namely:

**Sonic's [[mariowiki:File:MyS emblem Sonic.png|character icon]] in some ''Sonic'' spin-off games.

***It is also one of six to show the character's eyes, the others being {{SSBU|R.O.B.}}, {{SSBU|Kirby}}, {{SSBU|Meta Knight}}, [[Zombie]], and [[Enderman]]. This is not counting {{SSBU|Captain Falcon}} and [[Bowser Jr. (SSBU)|Larry]], as the eyes depicted for the former are not his actual eyes, and the latter lacks his irises.

*Sonic is one of three third-party characters in ''Ultimate'' with more than one [[Green Hill Zone|home]] [[Windy Hill Zone|stage]] representing their series, the others being {{SSBU|Cloud}} and {{SSBU|Sephiroth}}.

*In the credits, Jonatan Lopez, Sonic's Spanish voice actor, is misspelled as "Jonathan Lopez". This was also the case in ''Smash 4''.

**Coincidentally, Sergio Mesa and Manuel Gimeno, the Spanish voice actors of fellow ''Sonic'' characters [[Knuckles the Echidna|Knuckles]] and [[Shadow the Hedgehog|Shadow]], are also mispelled in the credits, as "Sergi Mesa" and "Manel Gimeno" respectively.

*Sonic, alongside {{SSBU|Mega Man}}, is one of two third-party characters with more than one [[Knuckles the Echidna|assist]] [[Shadow the Hedgehog|trophy]] representing their series.

*''Ultimate'' is the first game where Sonic was the first third-party character announced, as {{SSBB|Snake}} was announced before him in ''[[Super Smash Bros. Brawl]]'', while {{SSB4|Mega Man}} was announced before him in ''SSB4''.

*Sonic is one of only four characters to face a metal opponent in Classic Mode, facing a giant metal version of himself. The others are [[Bowser]], who faces [[Metal Mario]] upon normal Mario's defeat in the final round, [[Kazuya]], who faces a metal version of himself upon defeating his normal self in the final round and [[Sora]], who faces a metal version of himself in the sixth round.

*Sonic is the only character who travels to [[Green Hill Zone]] and [[Figure-8 Circuit]] in Classic Mode.

*Prior to version 2.0.0, there was a glitch that allowed {{SSBU|Ridley}} to instantly KO Sonic. On 2D stages, if Ridley grabbed Sonic with his [[Space Pirate Rush]] while Sonic was recovering from a Homing Attack near the ledge, Sonic would be instantly sent into the horizontal blast line.<ref>https://www.youtube.com/watch?v=zyylKx0Jgg8</ref>

*As is the case with ''SSB4'', Sonic's snoring and surfacing voice clips are taken directly from ''[[Super Smash Bros. Brawl]]'', in which he was voiced by Jason Griffith, despite otherwise being voiced by Roger Craig Smith.

**Also, like in ''SSB4'', Jason Griffith is uncredited in the credits.

*Sonic is the only third-party veteran to have his [[victory theme]] changed in some way, being slightly sped up and abridged at the end.

*The Chaos Emerald that appears in Sonic's victory pose is oddly more solid and less crystalline than the models used for his Final Smash and the [[Shadow]] Assist Trophy.

*Sonic's pose that he does in his official render in ''Ultimate'' has been [[List of Super Smash Bros. references in other franchises|referenced]] in at least two later sources of media:

**In the 2020 film, ''{{iw|wikipedia|Sonic the Hedgehog|film}}'', Sonic avoids one of Dr. Robotnik's attacks while striking a similar pose to his official render in ''Ultimate''. According to Sonic's actor {{iw|wikipedia|Ben Schwartz}}, this was an intentional reference.<ref>https://comicbook.com/gaming/2020/02/16/sonic-the-hedgehog-super-smash-bros-ultimate-easter-eggs/</ref>

**In a promotional image of the collaboration between ''Sonic'' and the 2020 action game ''{{iw|wikipedia|Ninjala}}'', Berecca (who wears a Sonic costume) strikes a pose identical to Sonic's official render in ''Ultimate''.<ref>https://www.sonicstadium.org/2020/09/sonic-x-ninjala-collaboration-details-revealed-costumes-eggman-utsusemi-and-more/</ref>

*In World of Light, Sonic is the only character unlocked in the Dark Realm with a power level lower than 10,000.

*When Sonic gets KO'd in Stamina battles, his "down" pose is similar to how he poses when hit by an enemy with no rings in 3D games from his series.

*In {{SSBU|Steve}}'s reveal trailer, Sonic's forward smash launches {{SSBU|Mario}} through blocks into a ''Minecraft'' cave (transitioning to a cinematic), which led to many jokes and memes about Sonic being able to "punch people into ''Minecraft''". The official Sonic Twitter page [https://twitter.com/sonic_hedgehog/status/1407383749377945602?s=20 referenced this meme] when an official ''Minecraft'' collaboration with the ''Sonic'' series took place.
