'''Sonic the Hedgehog''' ({{ja|ソニック・ザ・ヘッジホッグ|Sonikku za Hejjihoggu}}, ''Sonic the Hedgehog'') is the titular protagonist of the {{uv|Sonic the Hedgehog}} franchise and the mascot of [[Sega]]. After making a cameo in 1990’s ''{{s|wikipedia|Rad Mobile}}'',<ref>[http://didyouknowgaming.com/post/27783610171/sonic-the-hedgehog-rad-mobile-submitted-by-dr Did You Know? Sonic the Hedgehog in ''Rad Mobile'']</ref> Sonic debuted a few months later in [[wikipedia:Sonic the Hedgehog (1991 video game)|his eponymous game]]. In addition to succeeding {{s|wikipedia|Alex Kidd}} as Sega's mascot, Sonic was also the company's attempt at rivaling [[Nintendo]]'s mascot, [[Mario]], during the [[wikipedia:Fourth generation of video game consoles|fourth]] and early [[wikipedia:Sixth generation of video game consoles|sixth generations of video games]].<ref>[https://web.archive.org/web/20070715195921/http://uk.gamespot.com/gamespot/features/video/hist_sonic/ The History of Sonic the Hedgehog]</ref>

Sonic made his ''{{b|Super Smash Bros.|series}}'' debut in ''[[Super Smash Bros. Brawl]]'', in which he and [[Solid Snake]] notably became the first third-party characters to appear in the ''Super Smash Bros.'' series. Sonic has since reappeared as a fighter in ''[[Super Smash Bros. 4]]'' and ''[[Super Smash Bros. Ultimate]]''.

==Origin==
Sonic is a 15-year-old anthropomorphic hedgehog who, as his name suggests, is capable of running at supersonic speeds. He is 3 ft, 3 in (1 m) tall, weighs 77 lbs (35 kg), and has large quills, blue fur and green eyes. For attire, Sonic wears a pair of Power Sneakers<ref>Sonic the Hedgehog (16-bit) (Sega Mega Drive) United States instruction booklet, p. 2.</ref> alongside a pair of white gloves.

Before the original ''Sonic the Hedgehog'', Sonic debuted in the arcade racing game ''Rad Mobile'' as an ornament hanging on the driver's rearview mirror. Self-described as "The Fastest Thing Alive", Sonic is confident, quick-witted, carefree and virtuous, yet he can also be impulsive, hot-headed, snarky and cocky. He is also adventurous to the point that he hates being constrained. On a related note, Sonic's love of freedom is a primary reason behind his campaigns to stop subjugation of any kind, most notably the nefarious schemes concocted by his arch-nemesis, mad scientist Doctor Ivo "Eggman" Robotnik (who also curiously debuted before his own series, in ''Puzzle Construction'' for the Sega TeraDrive in 1991).

The ''Sonic the Hedgehog Technical Files'' written during development of the original ''Sonic the Hedgehog'' game state that Sonic's birthplace is Christmas Island — formally known as {{s|wikipedia|Kiritimati}}, one of the numerous atolls that comprise the real world sovereign state of {{s|wikipedia|Kiribati}}. This is affirmed by later interviews with Sonic Team staff.<ref name="christmas island"/> While Japanese profiles would follow suit with this statement, early western profiles stated that Sonic was an inhabitant of the fictional planet "Mobius". With the consolidation of the series' Japanese and western continuity starting in ''{{s|wikipedia|Sonic Adventure}}'', the concept of Mobius was mostly abandoned, and Sonic is currently considered an inhabitant of planet Earth. He lives a nomadic lifestyle and does not have a home.<ref>[https://automaton-media.com/en/news/sonic-the-hedgehog-is-still-homeless-sega-confirms/ Sonic the Hedgehog is still homeless, Sega confirms - AUTOMATON WEST]</ref>

Sonic's most defining feature is his speed, as it was his main gimmick and driving force during his inception. Sonic is constantly seen outrunning traditionally fast objects like cars and trucks, rockets, fighter jets and even time and space itself. This even applies to gameplay, with players often finding ways to glitch and sequence break several games by simply going fast enough. Aside from his speed, his main ability is to curl up into a ball and effectively make himself a projectile that can damage enemies. His most iconic method of achieving this state is the [[Spin Dash]], where Sonic curls up into a ball and spins around in place enough times to launch forward at high speeds. A variant of this technique called the Super Peel-Out exists, which has a similar effect except without curling into a ball. While Sonic initially could only jump and land on the heads of enemies, later games introduced the [[Homing Attack]], where Sonic will lock on to the closest enemy for a near guaranteed hit. Later games also introduced a boosting technique, where Sonic can further increase his speed by using a resource that varies depending on the game.

Sonic gathers golden rings for his primary source of health and energy. If he takes damage, the rings will fly out of him, the amount fluctuating depending on the game, and he has a few seconds to get them back before they disappear. Sonic also collects power-ups such as Power Sneakers that increase his speed further, various elemental shields that let him interact with the level in unique ways and allow him to take a hit without losing rings, invincible boxes that temporarily turn him invincible, several permanent power-ups that let him perform new techniques and access new areas, and wisps that temporarily change Sonic's abilities. 

Sonic's most iconic power-ups are the seven [[Chaos Emeralds]], which appear in most games as either collectibles or plot devices. Sonic has been shown to know how to perform Chaos Control, which is using the energy of at least one emerald to warp the fabric of reality, usually resulting in time slowing to a crawl or stopping entirely. If Sonic collects all seven emeralds, he can transform into [[Super Sonic]], which grants him flight and invincibility so long as he has a sufficient number of rings.

==In ''[[Super Smash Bros.]]''==
Although Sonic does not make any sort of appearance in ''Super Smash Bros.'', the game's Japanese website included his results from a poll to gauge interest for potential playable characters in a sequel.<ref>[http://www.sourcegaming.info/2015/03/23/if-there-were-a-smash-2-poll/ If there was a Smash 2 Poll]</ref>

==In ''[[Super Smash Bros. Melee]]''==
With the untimely demise of the {{s|wikipedia|Sega Dreamcast}} in early 2001, Sega was slated to become a strong supporter of the [[Nintendo GameCube]] by the time of its release. Because of this, Yuji Naka stated that Sonic was strongly considered to be playable in ''Melee'', but was ultimately not added due to time constraints.<ref>[[Media:YujiNakaInterview.jpg|Yuji Naka on the road - ''Edge Magazine'']]</ref> It was later revealed that both [[Shigeru Miyamoto]] and [[Masahiro Sakurai]] would have approved the idea of adding Sonic to ''Melee'' if there were no time constraints.<ref>[https://web.archive.org/web/20150617000827/http://www.gamnesia.com/news/miyamoto-liked-the-idea-of-sonic-in-smash-bros.-way-back-in-2001#.VYC6fi_P1qZ Miyamoto Liked the Idea of Sonic in Smash Bros. Way Back in 2001]</ref>

[[List of rumors#Sonic and Tails hoax|An infamous hoax claimed that Sonic and Tails were unlockable in ''Melee'']]. Despite it being confirmed that the rumor wasn't true, the hoax still became well-known in both the ''Super Smash Bros.'' community and the wider world of gaming anyway. This rumor got to such notoriety that the US website for ''Melee'' had to notify players in its FAQ that Sonic and [[Knuckles]] (who was not the subject of a major rumor) do not appear in the game.<ref>https://www.reddit.com/r/smashbros/comments/2huph9/here_have_an_old_faq_from_the_original_smash_bros/#lightbox</ref>

==In ''[[Super Smash Bros. Brawl]]''==
===As a playable character===
{{Main|Sonic (SSBB)}}
[[File:Sonic SSBB.jpg|thumb|left|Sonic, as he appears in ''Super Smash Bros. Brawl''.]]
Sonic makes his debut in the ''Super Smash Bros.'' series as a playable character in ''Super Smash Bros. Brawl'', and was confirmed on October 10th, 2007.<ref name=Dojo>[https://www.smashbros.com/wii/en_us/characters/sonic.html Smash Bros. DOJO!! - Sonic]</ref> According to [[Super Smash Bros. (series)|''Super Smash Bros.'' series]] creator [[Masahiro Sakurai]], Sonic's inclusion was not guaranteed; as a result of his last-minute inclusion, the delay of ''Brawl''{{'}}s release date was announced alongside his confirmation.<ref name=SourceGaming/>

According to Sakurai, he played a number of both classic and modern ''Sonic the Hedgehog'' games in order to develop a basis for Sonic's appearance in ''Brawl''. He was primarily focused on the classic games and based him on their gameplay style as one-button games.<ref name=SourceGaming>[https://www.sourcegaming.info/2016/07/24/sonic-the-hedgehog-joins-the-battle/ Sonic the Hedgehog Joins the Battle!! - Source Gaming]</ref> Aesthetically, Sonic's design is from ''Sonic the Hedgehog'' (2006) and ''Sonic and the Secret Rings'' (the latter being the origin of the model), and his [[dash]]ing animation is his Super Peel Out from ''Sonic the Hedgehog CD''.<ref name=SourceGaming/> Mechanically, his moveset largely consists of his attacks from ''Sonic the Fighters'',<ref name=SourceGaming/> although two of his [[special move]]s are the [[Homing Attack]] from ''Sonic Adventure'' and the [[Spin Dash]] from ''Sonic the Hedgehog 2''.<ref name=Dojo/>

Sonic's [[Final Smash]], [[Super Sonic]], functions almost identically to its appearances in his home series: he is rendered invincible and can fly, yet his transformation has a fairly short duration.<ref name=Dojo/> Possibly as a result of his last-minute inclusion, Sonic also appears very late in ''Brawl''{{'}}s [[Adventure Mode: The Subspace Emissary|The Subspace Emissary]]. Ultimately, he plays a pivotal role in the defeat of the mastermind behind the [[Subspace Army]], [[Tabuu]], during the final battle.

Sonic fittingly possesses the fastest [[dash]]ing speed in the game, as well as among the fastest [[walk]]ing and [[air speed]]s. His blisteringly fast mobility is further accentuated by Spin Dash and [[Spin Charge]], which enable him to blitz an opponent and are integral to his solid combo game. Sonic also possesses an excellent recovery, courtesy of his aforementioned air speed and the considerable distance granted by [[Spring Jump]]. However, Sonic's strengths are almost completely offset by his severely unimpressive KO potential, and most of his moveset generally has minimal utility.

Despite his flaws and the general consensus that he lacks truly advantageous and disadvantageous matchups, Sonic has nevertheless managed to achieve decent tournament results, even at the national level. As a result, he is currently ranked 22nd out of 38 on the [[tier list]]; this places him in the D tier, and posits him as a mid tier character.

==In ''[[Super Smash Bros. 4]]''==
===As a playable character===
{{Main|Sonic (SSB4)}}
[[File:Sonic SSB4.png|thumb|Sonic, as he appears in ''Super Smash Bros. 4''.]]
Sonic appears as a playable character in ''Super Smash Bros. 4'', with his return being confirmed during a [[Nintendo Direct]] on October 1st, 2013.<ref>[https://www.youtube.com/watch?v=X8khWAH13fg Nintendo Direct 10.1.2013]</ref> Unlike in ''Brawl'', he is now a starter character, and his design is now based on his appearance as of ''{{s|wikipedia|Sonic Unleashed}}'', which in turn was based on the CGI models from ''Shadow the Hedgehog'' and ''Sonic the Hedgehog'' (2006). This is further reflected by him now being voiced by Roger Craig Smith, who succeeded Jason Griffith in 2010. On a related note, Sonic is now fully voiced in Spanish, French, Italian, and German.

Sonic has been heavily buffed in the transition from ''Brawl'' to ''SSB4''. Sonic's previously abysmal KO potential has noticeably improved, and a number of his moves have improved utility. Outside of this, Sonic's outstanding speed and mobility have improved even further, thanks to his air and fast falling speeds becoming noticeably faster. Although Sonic's recovery was slightly weakened and some of his moves, particularly his KOing options, had their [[lag]] increased, these nerfs are largely outweighed by his aforementioned buffs.

Thanks to his improvements and consistent tournament success at all levels of play, Sonic is ranked 7th out of 55. This places him in the A tier, which ties him with {{SSB4|Fox}} and posits him as a top tier character.

==In ''[[Super Smash Bros. Ultimate]]''==
===As a playable character===
{{Main|Sonic (SSBU)}}
[[File:Sonic SSBU.png|thumb|Sonic, as he appears in ''Super Smash Bros. Ultimate''.]]
Sonic appears as a playable character in ''Super Smash Bros. Ultimate'', with his return being confirmed during Nintendo's E3 2018 presentation on June 12.<ref>[https://www.youtube.com/watch?v=L93H7YC-83o Super Smash Bros. Ultimate - E3 2018 - Nintendo Switch]</ref> Due to being the first character in {{SSBU|Mario}}'s {{SSBU|Classic Mode}} character unlock tree, Sonic can potentially be the first character unlocked in the game.

Sonic was nerfed slightly overall in the transition from ''SSB4'', with the changes he received demanding a more aggressive playstyle. Most notably, [[Spin Dash]] and [[Spin Charge]] can no longer [[cross-up]] shields or be charged indefinitely, with Spin Dash also losing its ability to be shield-canceled. As a result, both moves have become noticeably less effective as both neutral and camping options. Up aerial's angle and knockback adjustments have worsened its hits' consistency when Sonic is ascending, as well as its KO potential. However, it remains a useful combo starter when [[SHFF]]'d, thanks to its noticeably lower landing lag and the retention of its excellent auto-cancel window.

Despite these nerfs, Sonic received some noticeable buffs. [[Homing Attack]] is faster and more controllable, giving it greater combo potential and neutral utility. Adjustments to Spin Charge's angles, knockback, hitlag and SDI have improved its consistency significantly, while [[Spring Jump]] is even more useful for recovering thanks to it regaining the vertical height it had in ''Brawl''. Most of Sonic's standard attacks have also been strengthened or boast greater utility. Sonic has also been indirectly buffed by gameplay changes: he benefits from the expansion of [[dash-canceling]]'s utility more so than the rest of the cast because of his unrivaled dashing speed, and the reintroduction of directional air dodging allows him to extend his already impressive recovery.

==Trivia==
*Sonic has made the most ''Super Smash Bros.'' appearances out of any third-party fighter that has been playable in the series, having appeared in all games since his debut in ''Super Smash Bros. Brawl''.
*Sonic is the only third-party fighter to undergo a redesign between games. He uses a modified version of his model from ''Sonic and the Secret Rings'', with much more detailed textures that have the colored shading of Yuji Uekawa's artwork, in ''Brawl''. From ''SSB4'' onwards, his design is his standard look as of ''Sonic Unleashed'' (previously used in pre-rendered cutscenes and promotional renders from other ''Sonic'' games) with elements from the Classic and Uekawa designs. ''Wii U'' uses a new model designed to fit the ''Brawl'' model's animation rig, while ''3DS'' reuses the ''Brawl'' model with some modifications to better resemble the ''Wii U'' model. ''Ultimate'' uses a heavily remodeled version of the ''Wii U'' model. The ''3DS'' model oddly enough retains the Uekawa-esque shading of the ''Brawl'' model that is gone from the models in ''Wii U'' and ''Ultimate''.
**Additionally, he is the only third-party fighter to have their voice actor changed between installments, switching from Jason Griffith to Roger Craig Smith in ''SSB4''. However a few of Griffith's voice clips, such as Sonic's snoring and water surfacing sound, are still used in ''SSB4'' and ''Ultimate''.
*Sonic is unable to [[swim]] in his own series, due to Yuji Naka (one of his creators) mistakenly believing that hedgehogs in real life cannot. Sonic typically sinks to the bottom when in water; in ''Sonic Colors'', he can jump indefinitely but not properly "swim", and swimming events in ''Mario & Sonic at the Olympic Games'' show him using water wings to stay afloat. This is often, though inconsistently, depicted as Sonic having some form of thalassophobia. Because swimming is a universal game mechanic in the ''Super Smash Bros.'' series, Sonic is able to swim. However, to reflect his adverse mobility in water in his home series, his very frantic swimming style makes him among the slowest swimmers in the series. In ''Ultimate'', this trait is further accentuated: Sonic's swimming animation is closer to his drowning animation, and he receives damage while swimming.
*Sonic is the only fighter who debuted on a [[Sega]] console.
*Sonic, [[Mewtwo]], [[Joker]] and [[Terry Bogard]] are the only fighters to have more than one reveal trailer.
**Of those four, he is the only one who was not DLC at the time, and whose trailers contained actual gameplay (the latter three only had gameplay in their second trailer), were for two separate installments (being ''Brawl'' and ''SSB4''), and did not have splash art.
**Both trailers feature the ending segment of the song that is not included in-game for the ''Super Smash Bros.'' series.
**Furthermore, in the case of ''SSB4'', he was the first veteran in the series to have a dedicated reveal trailer, followed by {{SSB4|Mewtwo}}, {{SSB4|Lucas}} and {{SSB4|Roy}}. Of those four, he is the only one who is not DLC and whose trailer lacked both splash art and a tagline.
*In ''Brawl'', Sonic was only voiced in Japanese and English. However, in ''SSB4'', he gained voice acting in Spanish, Italian, German, and French. This is because the ''Sonic'' games began receiving dubs into non-English languages with ''Sonic Generations'', which released between ''Brawl'' and ''SSB4''.
