'''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. Sonic is classified as fighter #38.

As in ''SSB4'', {{s|wikipedia|Roger Craig Smith}}'s portrayal of Sonic from ''Sonic Generations'' and ''Mario & Sonic at the London 2012 Olympic Games'' and {{s|wikipedia|Jun'ichi Kanemaru}}’s portrayal of Sonic from ''[[Super Smash Bros. Brawl|Brawl]]'' were repurposed for the English and Japanese versions of ''Ultimate''. {{s|wikipedia|Alexandre Gillet}}, Jonathan López, Marc Stachel and Renato Novara's portrayals of Sonic from various ''Sonic'' games used in ''[[Super Smash Bros. 4|Smash 4]]'' were also repurposed for the French, Spanish, German, and Italian versions, respectively.

==How to unlock==
Complete one of the following:
*Play [[VS. match]]es, with Sonic being the 17th character to be unlocked.
*Clear {{SSBU|Classic Mode}} with {{SSBU|Mario}} or anyone in his unlock tree, being the 1st character unlocked.
*Have Sonic join the player's party in [[World of Light]].

With the exception of the third method, Sonic must then be defeated on [[Green Hill Zone]].

==Attributes==
Sonic is a [[weight|lightweight]] who, staying true to his home series, has very fast mobility. He possesses the fastest [[dash]] speed in the game by default (surpassed only by [[Hero (SSBU)|Hero]] under the effects of [[Command Selection|Acceleratle]]), the 7th fastest [[walk]] speed, the 12th fastest [[air speed]] (tied with [[Mario (SSBU)|Mario]], [[Donkey Kong (SSBU)|Donkey Kong]], [[Little Mac (SSBU)|Little Mac]] and [[Inkling (SSBU)|Inkling]]), and the highest [[traction]]. Combined with his above-average [[fall speed|falling speed]], Sonic can move across the stage at blinding speeds despite his slow [[air acceleration]]. In addition, he can 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. 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. 

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.

[[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 K.O. 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 [[edge-guarding]] and, in certain instances, can combo into itself on-stage at low percentages, thanks to its [[auto-canceling]] window and Sonic's fast airspeed. 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 powerful, making it one of his few reliable KOing options 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.

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 and is one of the factors that makes him so difficult to play competitively. 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 of which is his KO potential. His KO potential is held back by his most reliable KOing options (smash attacks, and clean back aerial) requiring good positioning and having noticeable start-up 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 down smash, while having a decent start-up, has high ending lag, making it easy to punish if missed. While his damage-racking potential is formidable, his actual ability to close out a stock is one of the worst in the game, often resulting 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. 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 play-style 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 Sonic 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, has 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 KOing.

==Changes from ''[[Super Smash Bros. 4]]''==
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|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 has been slightly 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 mind games from ''Smash 4'', and now requires 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. [[Homing Attack]] has been significantly buffed, now having faster startup, less endlag upon hitting an opponent, better homing capabilities, 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. [[Down tilt]] now launches opponents at a higher angle, granting the move combo potential. All his smash attacks were improved, with [[forward smash]] gaining more range, and [[up smash|up]] and [[down smash]] have increased KO potential. Additionally, some of Sonic's already stronger 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.

|neutral1dmg=2%
|neutral2dmg=1.5%
|neutral3dmg=4%
|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.
|ftiltname=&nbsp;
|ftiltdmg=4% (hit 1), 7% (hit 2 feet), 5% (hit 2 legs)
|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, or as an [[out of shield]] option. 
|utiltname=&nbsp;
|utiltdmg=2% (hit 1), 6% (hit 2)
|utiltdesc=A {{s|wikipedia|540 kick}}, similar to {{SSB4|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''.
|dtiltname=&nbsp;
|dtiltdmg=6%
|dtiltdesc=A legsweep. Its diagonal angle can lead to combos at lower percents. It resembles the Leg Throw from ''Sonic the Fighters'' and the leg sweep from ''Sonic the Hedgehog 2006'' and ''Sonic Unleashed''.
|dashname=
|dashdmg=6% (clean), 4% (late)
|dashdesc=A flying kick similar to Fox's. It is a reliable follow-up from a down throw. While its very minimal start-up lag can allow it to pressure unwary opponents, it is very punishable because of its considerable ending lag.
|fsmashname=&nbsp;
|fsmashdmg={{ChargedSmashDmgSSBU|14}}
|fsmashdesc=The Wind-Up Punch from ''Sonic the Fighters''. It has high knockback growth, deceptive range, and can be angled, all of which make it one of Sonic's most viable KOing options. However, its very low base knockback makes it better suited for KO attempts later instead of earlier. It also has noticeable start-up and ending lag, making it risky if used unwisely.
|usmashname=&nbsp;
|usmashdmg={{ChargedSmashDmgSSBU|5}} (hit 1), {{ChargedSmashDmgSSBU|1}} (hits 2-7), {{ChargedSmashDmgSSBU|3}} (hit 8)
|usmashdesc=A jumping Spin Dash. It hits multiple times, with its last hit having extremely high knockback growth. However, its last hit has average base knockback, which makes it better suited for KO attempts later instead of earlier. 
|dsmashname=&nbsp;
|dsmashdmg={{ChargedSmashDmgSSBU|12}}
|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 has considerable ending lag.
|nairname=&nbsp;
|nairdmg={{ShortHopDmgSSBU|12}} (clean), {{ShortHopDmgSSBU|8}} (late), {{ShortHopDmgSSBU|5}} (latest)
|nairdesc=Curls up into a ball and spins while slightly undulating up and down. In addition to being a reliable follow-up from [[Spin Dash]], [[Spin Charge]], and Spring Jump-assisted combos, its launching angle makes its clean and late hitboxes into useful combo starters at low to medium percentages when [[SHFF]]'d. It resembles the Air Spin from ''Sonic the Fighters'' and the Insta-Shield, an attack that debuted in ''Sonic the Hedgehog 3''.
|fairname=&nbsp;
|fairdmg={{ShortHopDmgSSBU|0.8}} (hits 1-5), {{ShortHopDmgSSBU|3}} (hit 6)
|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 its last hit's very high knockback growth, it is useful for spacing and edge-guarding. It can also combo into itself in certain instances, thanks to Sonic's fast air speed and its fairly large [[auto-canceling]] window. It resembles the Emerald Dive from ''Sonic the Fighters''.
|bairname=&nbsp;
|bairdmg={{ShortHopDmgSSBU|14}} (clean), {{ShortHopDmgSSBU|10}} (late)
|bairdesc=A hook kick. Its clean hitbox's impressive damage output and high knockback growth make it one of Sonic's most viable KOing options, especially when used for edge-guarding. However, it has moderate start-up.
|uairname=&nbsp;
|uairdmg={{ShortHopDmgSSBU|3}} (hit 1), {{ShortHopDmgSSBU|8}} (hit 2)
|uairdesc=A scissor kick. Its very large auto-cancel window makes it deceptively safe and easy to avoid even its fairly low landing lag. In addition to being a reliable follow-up from Spin Dash, Spin Charge, and Spring Jump-assisted combos, it is a viable KOing option near the upper blast line, especially as a follow-up from Spring Jump. Both hits don't always connect very reliably however.
|dairname=Shooting Star Kick
|dairdmg={{ShortHopDmgSSBU|8}} (clean), {{ShortHopDmgSSBU|7}}/{{ShortHopDmgSSBU|5}} (late)
|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 it having noticeably less 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''.
|grabname=
|grabdesc=[[wikipedia:Grappling hold#Clinch hold|Clinches]] the opponent. 
|pummelname=
|pummeldmg=1.3%
|pummeldesc=A knee strike. A fairly fast pummel.
|fthrowname=
|fthrowdmg=1% (hit 1), 6% (throw)
|fthrowdesc=A stretch kick. Due to its average damage output, very high base knockback, and average knockback growth, it is mainly used to force the opponent off-stage. It also has KO potential, albeit only on edges and at very high percents. It resembles the Top Kick from ''Sonic Battle''.
|bthrowname=
|bthrowdmg=7%
|bthrowdesc=Quickly backflips repeatedly with the opponent in tow before performing the {{s|wikipedia|tomoe nage}}{{ref|b}} (a Judo throw). It is Sonic's only throw with consistent KO potential.
|uthrowname=
|uthrowdmg=1% (hit 1), 5% (throw)
|uthrowdesc=Heaves the opponent upward and sharpens his quills to stab them. It can be followed up with a neutral aerial, up aerial and inputted Homing Attack at low percentages. Like forward throw, it has KO potential, albeit only on with stages with highly positioned platforms, such as Battlefield's top platform.
|dthrowname=
|dthrowdmg=1% (hits 1-3), 5% (throw)
|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''.
|floorfname=
|floorfdmg=6%
|floorfdesc=Spin Dashes around in a circular motion while getting up.
|floorbname=
|floorbdmg=7%
|floorbdesc=Performs a legsweep while getting up.
|floortname=
|floortdmg=5%
|floortdesc=Performs a legsweep while getting up.
|edgename=
|edgedmg=9%
|edgedesc=Spin Dashes forward while climbing up. It resembles the Cliffhanger Flip from ''Sonic the Hedgehog Spinball''.
|nsname=Homing Attack
|nsdmg=7%-20%
|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 comboed into from various moves if executed early.
|ssname=Spin Dash
|ssdmg=7%-10.9% (dash), 5% (initial jump), 3% (jump)
|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.
|usname=Spring Jump
|usdmg=— (jump), 4% (spring)
|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.
|dsname=Spin Charge
|dsdmg=1.5%-2.3% (loop), 4% (last hit), 6% (jump)
|dsdesc=A Spin Dash that hits multiple times and has more momentum. It also has slightly different aesthetics, and requires button mashing in order to charge. However, it lacks the short jump at the beginning, cannot be canceled in any way, and it can only become a "Spin Shot" when used in the air.
|fsname=Super Sonic
|fsdmg=12% (Chaos Emeralds), 6% (each ram), 10% (detransformation)
|fsdesc=Summons the Chaos Emeralds and uses them to attain his Super Transformation from the ''Sonic the Hedgehog'' games. When activated while very close to an opponent, the Chaos Emeralds will damage the opponent. Upon being activated, Sonic is invincible during its duration, and flies around rapidly horizontally and can change his horizontal position. Any opponents that are near Sonic when he returns to normal will be damaged.

==In competitive play==
Upon ''Ultimate's'' release, Sonic was initially seen as a far less viable character comparative to ''Smash 4'' due Spin Dash no longer being able to be shield canceled, Spin Charge no longer crossing up shield without a full charge, up air failing to connect at times and Spin Charge's inconsistent ability to knock opponents upward with the jump, with the former being arguably his worst change. This has led to a mixed reception of him, and he was seen as a mid tier character in general, with some top players even ranking him as far as low tier.

However, he retained his superb mobility, long distanced recovery and combo game, along with a potent set of KO moves. 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. Despite his overall viability still being up for debate, the general perception of him has become significantly favorable, with many professional players arguing that he's a solid high tier at minimum.

Most recently, Sonic's results have increased even further due to tournaments needing to be held online, which arguably benefits Sonic more than many other characters as his camping ability is even harder to deal with when combined with the game's online having notoriously high input lag. This has caused a controversial perception of Sonic in competitive play, as many players have grown tired 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 agreed that timing matches out by camping with him should be banned.

Overall, Sonic is one of only four ''Smash 4'' top tier veterans (the other three being {{SSBU|Mario}}, {{SSBU|Fox}}, and {{SSBU|Zero Suit Samus}}) who continues to earn great representation and consistently places well in tournaments.

<!--If you are planning to add a player you consider to be notable, please provide tournament results in some shape or form in the edit summary (be it a link to a results thread or bracket of placing high in a tournament of other notable players or a video of them beating a notable player). Winning tournaments without notable players present is generally not enough to warrant a spot.-->

=={{SSBU|Classic Mode}}: At the Speed of Sound==
[[File:SSBU Congratulations Sonic.png|thumb|Sonic's congratulations screen.]]
Sonic's opponents in Classic Mode are a mix between the game's fastest characters as well as references to characters in other ''Sonic'' titles. The references to his games in Sonic's Classic Mode go in chronological order from each console generation starting from the 4th (Sega Genesis) to the 8th (Wii U).

Note: Every stage other than the final round plays a track from the ''Sonic'' universe, no matter what universe the stage originated from.

==Role in [[World of Light]]==
[[File:WoL-38Sonic.jpg|thumb|Finding Sonic in World of Light|left]]
Sonic was among the fighters summoned to the cliffside to assist in defeating an army of [[Master Hand]]s.

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.

==[[Spirit]]s==
Sonic's Fighter Spirit can be obtained by completing [[Classic Mode]]. It is also available periodically for purchase in the shop for 500 coins. Unlocking Sonic in World of Light allows the player to preview the first spirit below in the Spirit List under the name "???". As a Fighter Spirit, it cannot be used in Spirit Battles and is purely aesthetic. Each Fighter Spirit has an alternate version that replaces them with their artwork in ''Ultimate''.

Additionally, Sonic makes an appearance in a few Primary Spirits in other forms.

==Trivia==
[[File:SonicUltimateMoviePose.jpeg|thumb|Sonic recreating his ''Ultimate'' render pose in the 2020 ''Sonic the Hedgehog'' film.]]
*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.
**This tip is recycled from ''Smash 4'', where it is correct, as Spring Jump in said game does not incur additional landing lag.
***It could however mean 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:
**The logo for {{s|wikipedia|Sonic Team}}. 
**Sonic's [[mariowiki:File:MyS emblem Sonic.png|character icon]] in some ''Sonic'' spin-off games.
**The [https://sonic.wikia.com/wiki/File:One_up_sonic_dif.png life icon and 1-ups] in ''{{s|wikipedia|Sonic Unleashed}}'' (when Sonic is not in his Werehog form), as well as [https://sonic.wikia.com/wiki/File:Cmn_obj_oneup_dif_SD.png the 1-ups] from ''{{s|wikipedia|Sonic Colors}}''.
***It is also one of four to show the character's eyes, the others being {{SSBU|R.O.B.}}, {{SSBU|Kirby}}, and {{SSBU|Meta Knight}}. 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 the only third-party character in ''Ultimate'' with more than one home stage representing his series.
*Sonic, alongside {{SSBU|Mega Man}}, is one of two third-party characters with more than one assist trophy representing their series.
*Unlike other installments in the ''Super Smash Bros.'' series, Sonic slowly takes damage if he falls in any body of water, which is a nod to his inability to [[swim]] in his own series.
**This makes Sonic the only third-party fighter to have this trait.
*While Sonic has appeared in three installments, ''Ultimate'' marked the first time 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 ''[[Super Smash Bros. 4]]''.
*Sonic is one of only two characters to face a metal opponent in Classic Mode. The other is [[Bowser]] who faces [[Metal Mario]] upon normal Mario's defeat in the final 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 ''Smash 4'', 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 ''Smash 4'', Jason Griffith is uncredited in the credits.
*With the exception of his Japanese voice and the aforementioned ''Brawl'' voice clips, Sonic is among the few voiced fighters in ''Ultimate'' whose voice clips are sourced from their own games rather than specifically recorded for a ''Smash'' game. He shares this trait with {{SSBU|Inkling}}, {{SSBU|Bowser Jr.}} and the Koopalings, {{SSBU|Daisy}}, {{SSBU|Rosalina & Luma}}, {{SSBU|Yoshi}}, {{SSBU|Banjo & Kazooie}}, {{SSBU|Young Link}} and {{SSBU|Toon Link}}.
**Of these fighters, Sonic and Banjo & Kazooie are the only third-party fighters with this distinction.
*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.
**So far, Sonic and {{SSBU|Joker}} are the only 2 characters to have their victory themes ripped directly from their respective games.
**Both of these characters are also Sega representatives.
*''Ultimate'' is the first game since ''Brawl'' that features Sonic in a CG cutscene.
*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.
*In the 2020 film, ''{{iw|wikipedia|Sonic the Hedgehog|film}}'', Sonic avoids one of Robotnik's attacks while [[List of Super Smash Bros. references in other franchises| 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 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.
*When fighting off the fifty puppet fighter army as Master Hand in World of Light, Sonic is one of the eight fighters fought there, being affiliated with Dharkon.
*If Sonic's size changes due to a [[Super Mushroom]], [[Poison Mushroom]], or something else while charging [[Homing Attack]], Sonic will no longer gain height.
