Sonic

Sonic the Hedgehog is the eponymous main protagonist of the  franchise. He has been Sega Corporation's mascot since June 23, 1991 after replacing the previous mascot Alex Kidd. Since the beginning of the series, Sonic has been the champion of peace, risking his life to stop the plots of a variety of violent foes, particularly Dr. Eggman, in order to establish worldwide peace. Along the way, he has been aided by many characters, including his friends Miles "Tails" Prower, Knuckles the Echidna, Amy Rose, and Shadow the Hedgehog. Sonic's greatest asset is his ability to run at supersonic speeds, hence his name. However, he is also prone to making rash decisions and dislikes being near water because he cannot swim, with certain exceptions.

Sonic has appeared in crossover titles alongside Mario in the Mario & Sonic series and the Super Smash Bros. series.

For the first two Mario & Sonic games and Super Smash Bros. Brawl, Sonic was voiced in English by Jason Griffith, his at-the-time current voice actor in the Sonic the Hedgehog series. However, as of the release of Sonic Free Riders and Sonic Colors in 2010, Roger Craig Smith currently provides the English voice of Sonic. Unlike Mario, Sonic usually has full voice acting.

Concept and creation
In April of 1990, Sega requested a game that would be capable of selling at least one million copies, being able to both compete against Nintendo's Mario and replace their at the time current mascot, Alex Kidd. Several character designs were submitted, and eventually the mascot they selected was a spiky teal hedgehog named "Mr. Needlemouse", who was later renamed Sonic, submitted by Naoto Oshima. Some of the original concepts for Sonic depicted him as being in a band, as well as a human girlfriend named Madonna who would have played a similar role to Princess Peach in Super Mario Bros., though these were scrapped during development. After a few minor adjustments and redesigning, Sonic Team developed the first title in what would become the phenomenally successful Sonic the Hedgehog series.

Rivalry
Nintendo and Sega were business rivals throughout the 1990's, though mostly during the competition of the Super Nintendo Entertainment System and the Sega Genesis / Mega Drive. As such, Nintendo and Sega often attempted to put each other down in their games. Examples of Nintendo mocking Sega include the "No Hopers" sign in Donkey Kong Country 2: Diddy's Kong Quest, and possibly the Harry Hedgehogs of Super Mario World 2: Yoshi's Island, while examples of Mario mockeries in the Sonic the Hedgehog series forms of media include the emphasis on "Super" on the back of Sonic the Hedgehog's box (a reference to Super Mario Bros. and other Mario series titles beginning with "Super") and the Marxio Brothers of Sonic the Comic, a British comic book about Sonic and his friends. Their rivalry lasted until 2001 when Sega left the console manufacturing market with the discontinuation of their last console, the Dreamcast (in America and Europe) and became a third-party game developer. The first Sonic games for a Nintendo system were Sonic Advance for Game Boy Advance and an enhanced port of Sonic Adventure 2 for the Nintendo GameCube, titled Sonic Adventure 2: Battle. Both were released simultaneously in Japan.

Donkey Kong Country 2: Diddy's Kong Quest
In the Cranky's Video Game Heroes awards ceremony in Donkey Kong Country 2: Diddy's Kong Quest, Sonic's shoes and Earthworm Jim's plasma gun can be seen next to a trash can, along with a sign saying "No Hopers." This detail was removed for the Game Boy Advance port, released after Sega became a third-party.

Mario & Sonic at the Olympic Games
"Mario and Sonic have been respectful rivals since the early days of video games. In fact, for a long time they have been discussing the possibility of one day competing against each other. Now that they have been given the perfect opportunity to meet at the Olympic Games, we may finally learn who is actually faster, Mario or Sonic?"

- Shigeru Miyamoto

Sonic competes against Mario and others in Olympic events in the game Mario & Sonic at the Olympic Games. He is a Speed character, meaning he has great speed, but low power. Sonic wears a yellow life jacket during the swimming events, since he can't swim; however, he moves quite fast in water as well as out of it.

Mario & Sonic at the Olympic Winter Games
Sonic, once again, crosses over with Mario in Mario & Sonic at the Olympic Winter Games. As in Mario & Sonic at the Olympic Games, he is a Speed type character and is the fastest one in the game. In the Adventure Tours mode for the DS version, Bowser and Dr. Eggman team up to ruin the 2010 Olympics. Bowser melts all of the snow at the event, and Dr. Eggman kidnaps the snow spirits to prevent any snowfall. Sonic and Mario team up in order to put a stop to Bowser and Dr. Eggman's plans and to save the snow spirits.

Mario & Sonic at the London 2012 Olympic Games
Sonic makes yet another crossover appearance with Mario and friends in Mario & Sonic at the London 2012 Olympic Games. Like in the previous two installments of the series, Sonic is a Speed type character. This game is notable for being the first in the series to feature Roger Craig Smith as Sonic's new voice actor. Sonic has dialogue for the Wii version of the game in the London Party mode, but not the 3DS version's Story Mode.

In the 3DS version's Story Mode, Sonic is first seen with Miles "Tails" Prower arriving at London for the Olympic Games. Not long after the two arrive, red fog starts appearing; Sonic and Tails decide that this is Bowser and Eggman's doing and later meet up with Mario, Luigi, and Toad to put a stop to the evil villians' plot. After their defeat, Bowser and Dr. Eggman claimed they never got their invitations to the games which is the reason why they started the plot. In reality, they mistook their invitations for love letters since Princess Peach and Amy wrote them. After clearing up the problem, Sonic, Tails, Mario and Luigi invite Bowser and Dr. Eggman to the Opening Ceremony so they can all compete in the Olympic Games.

Mario & Sonic at the Sochi 2014 Olympic Winter Games
Sonic also appears as a playable character in Mario & Sonic at the Sochi 2014 Olympic Winter Games. He is once again a Speed type character.

Mario & Sonic at the Rio 2016 Olympic Games
Sonic returns as a playable Speed type character in Mario & Sonic at the Rio 2016 Olympic Games. In the 3DS version, Sonic, along with Mario, can be used in any of the game's events. This is the first Nintendo 3DS Mario & Sonic game to give Sonic in-game text dialogue, as opposed to his silence in previous games.

Mario & Sonic at the Olympic Games Tokyo 2020
Sonic reappears in Mario & Sonic at the Olympic Games Tokyo 2020 as a playable Speed type character. Like many other characters in the game, Sonic wears appropriate clothing depending on the event. He is one of the eight characters that are playable in 2D Events. In the game's Story Mode, Sonic gets sucked into a game system along with Mario, Toad, Bowser and Dr. Eggman, and decides to compete in the Tokyo 1964 Olympic Games.

Super Smash Bros. Brawl


Sonic is an unlockable playable character in Super Smash Bros. Brawl, and, alongside Solid Snake, is one of the first two non-Nintendo characters to appear as playable characters in the series. He can be unlocked by playing 300 Brawl matches, completing Classic with ten characters, playing ten hours of Brawl matches, or by having Sonic join the party in The Subspace Emissary; with any of the first three methods, the player must then defeat Sonic on Green Hill Zone. Sonic was not originally planned to appear; he was included during development in 2007, making him the final character created from the ground up to be added into the game.

Sonic is the fastest character in the game, with fast attacks and movements. Several of Sonic's moves are based on those he uses in his games. His standard special is the Homing Attack, which involves him flying right into opponents, his down special and side special are Spin Dash and Spin Charge, respectively, which both involve him curling into a ball and ramming into opponents, and his up special is Spring Jump, which involves him leaping up off of a spring from the Sonic series. His Final Smash move is using the Chaos Emeralds to transform into Super Sonic, allowing him to fly around the stage to attack.

Sonic's victory theme is directly taken from the 2006 Sonic the Hedgehog game, that tune being an arrangement of the "Act clear" theme from Sonic the Hedgehog 3 and most Sonic games after that. This makes him the first character in the series whose victory theme is ported directly from a non-Super Smash Bros. game.

The Subspace Emissary
Sonic does not appear in the Subspace Emissary until the very end, after The Great Maze. As every fighter makes it to where Tabuu resides, he prepares his Off Waves, which would have turned every character into a trophy. As soon as he's about to release the attack, a blue blur dashes past the fighters, and rams into both of Tabuu's wings, causing the Off-Wave attack to fail. As the blue blur jumps up on a "peak", he reveals himself to be Sonic. While he taunts, Tabuu's wings break apart, and then six fighters are selected to fight Tabuu in the final battle. Sonic, along with Jigglypuff, Squirtle, Toon Link, Wolf O'Donnell, and Zero Suit Samus, is one of the only characters that are never seen as trophies in The Subspace Emissary.

Super Smash Bros. for Nintendo 3DS / Wii U


Sonic reappears in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U as a playable character making him the first veteran third-party character. This time, however, he is available from the start. He is also now voiced by Roger Craig Smith in English instead of Jason Griffith; additionally, he is now voiced by a different voice actor in different regions (e.g. he has a French voice in France). However, his voice clips are recycled voice clips from other games, with his voice clips of rising from water (only in the Wii U version), sleeping, and one of his attack grunts being archival recordings of Jason Griffith from Super Smash Bros. Brawl. His appearance has been updated to reflect his design in his more recent games such as Sonic Colors, which in turn are based on official 2D and CG artworks.

His moveset is almost completely unchanged from Super Smash Bros. Brawl; the only real changes are that his down smash from the previous game (a back-and-forth Spin Dash) has been replaced with a split-kick, while his dash attack (a Spin Dash) has him perform a lunging kick afterwards. Sonic's overall damage output is lowered, but many of his attacks deal more knockback. Sonic's air speed and fast-falling speeds are both faster, while his walking speed is slightly slower.

One of his alternate colors in this game seems to be based off Silver the Hedgehog. Along with Sonic himself, a stage based on Windy Hill Zone from Sonic Lost World makes an appearance in Super Smash Bros. for Wii U as well as the returning Green Hill Zone appearing in Super Smash Bros. for Nintendo 3DS.

Super Smash Bros. Ultimate
Sonic returns as a playable character in Super Smash Bros. Ultimate. Like Super Smash Bros. Brawl, Sonic is an unlockable character instead of being available from the start. Sonic's basic moveset appears mostly unchanged aside from his dash attack, which is now solely a lunge kick. His Final Smash, Super Sonic, returns, but he travels much faster than before, and he moves automatically back and forth while his height can be adjusted, in a vein similar to Pac-Man's Final Smash. As with several other returning characters, Sonic's victory theme has been slightly shortened compared to the previous installments. Both Green Hill Zone from Super Smash Bros. Brawl and Windy Hill Zone from Super Smash Bros. for Wii U return as well.

Like all other characters in the game, Sonic receives benefits from universal changes: his already quick mobility is much faster; his aerial attacks have less landing lag; his short hop timing is reduced; he can directionally air dodge to aid his recovery; and he can use any grounded attack out of a run and any of his aerial attacks while climbing ladders. In a similar vein to fellow veteran Charizard and newcomers Inkling and Incineroar, Sonic takes minor damage from swimming in water; this is due to him being unable to swim in his home games.

In the World of Light trailer, Sonic tries to run away from Galeem's large laser attack, but slows down in an attempt to save Pikachu; this fails, with both of them being captured by Galeem and used to create puppet fighters. Sonic is found in the "Sacred Land" sub-area of the Dark Realm, and is one of the fighters required to be defeated to progress.

Classic Mode route
In his Classic Mode route, Sonic battles against fighters based on various characters he encounters throughout the Sonic franchise.

Homing Attack


The Homing Attack is one of Sonic's moves appearing in most games in his series since Sonic Adventure, and his standard special move in the Super Smash Bros. series. When used, Sonic curls up into a ball and hovers in the air before charging down and forward, hitting any nearby opponents. The player can also have Sonic immediately charge forward by pressing the special attack button again, though the move is weaker as a result. The Homing Attack causes Sonic to bounce off of the opponents if it hits, in addition to walls and the ground if it misses.

In Super Smash Bros. Ultimate, crosshairs briefly appear on Sonic's target when the Homing Attack is used. The move is also used by Knuckles when he is summoned from an Assist Trophy.

In Super Smash Bros. for Nintendo 3DS / Wii U, the Homing Attack is given two custom variants. The first is Stomp, another move from the Sonic the Hedgehog series that causes Sonic to slam directly downward into opponents and meteor smash them. The second move is Surprise Attack, which is faster, but Sonic stays in place while charging and the attack sends Sonic into the air a little, giving the move less range.

Spin Dash


The Spin Dash is Sonic's side special move, based on the move that he has had in the Sonic the Hedgehog series since Sonic the Hedgehog 2. Rather than rapidly pressing the button like in the Sonic games, the Spin Dash in the Super Smash Bros. series instead charges by holding down the special attack button. Sonic curls up into a ball as the move charges, and when the button is released Sonic charges forward, damaging any enemies in his path while doing a small hop at the beginning. The player can change the direction of the dash by tilting the control stick in the other direction. Players can also jump while dashing by pressing any button.

In Super Smash Bros. for Nintendo 3DS / Wii U, the Spin Dash has two custom variants that can be unlocked: Hammer Spin Dash and Burning Spin Dash. Hammer Spin Dash causes Sonic to leap into the air and slam the ground upon dashing, burying any opponents beneath him, though the move does not have as much attack power. Burning Spin Dash has a fire effect, but does not have the hop at the beginning of the move.


 * Names in other languages

Spring Jump


Spring Jump is Sonic's up special move. When used, Sonic summons a Spring from the Sonic the Hedgehog series underneath him and uses it to bounce upwards. He can use this both on the ground and in mid-air. If he uses it on the ground, it stays in place for a while, allowing him and other characters to bounce on it as well. Sonic cannot do damage when using the spring; however, he can still use his aerial moves (but no special moves) afterwards (one of very few up special moves that can do so). When the spring falls in midair and hits an opponent, it sends them straight downwards and deals some minor damage. Sonic can also use this move to recover from getting knocked off the edge of a stage.

In Super Smash Bros. for Nintendo 3DS / Wii U, Spring Jump has two custom variants: Double Spring and Springing Headbutt. Double Spring allows Sonic to summon another spring in mid-air after using the first, but reduces the jump height to compensate. Springing Headbutt causes Sonic to attack on the initial jump, but the spring disappears when it touches the ground and the jump is also slightly lower.

Spin Charge


The Spin Charge is Sonic's down special move. It is a Sonic technique that originated from Sonic the Hedgehog 2. The attack is very similar to the Spin Dash, but it has the potential to move faster. If Sonic uses this attack, the player must tap the special move button repeatedly to charge the attack even further. It also lacks a hop at the start, unlike Spin Dash. Charging it up gives it a huge power and speed boost, more so than the Spin Dash's charge. When the player taps the special move button but doesn't keep tapping it, Sonic will stop spinning, which could fake out the opponents. The attack is also very similar to Jigglypuff's Rollout attack.

In Super Smash Bros. for Nintendo 3DS / Wii U, the Spin Charge has two custom variants: Auto-Spin Charge and Gravitational Charge. Auto-Spin Charge removes the need of tapping the B button repeatedly for it to charge. Gravitational Charge pulls opponents in front of Sonic and towards him, then pushes them behind him and away from him.

Super Sonic
"NOW I'LL SHOW YOU! HRRRRRRRRGGGGGGGHHHHHHHH...!!!"

- Sonic the Hedgehog

Super Sonic is a form that is taken by Sonic when he collects the seven Chaos Emeralds that appears in many installments in the Sonic the Hedgehog series, first appearing in Sonic the Hedgehog 2, and also appears as his Final Smash. When activated, the Chaos Emeralds appear around Sonic and transform him into Super Sonic, allowing him to freely fly around at high speed, ramming into opponents to deal damage. After some time, the transformation ends and Sonic returns to normal. The player cannot self-destruct while using this Final Smash, as Super Sonic cannot fly past the stage's blast lines.

In Super Smash Bros. Ultimate, the Final Smash is now automatic, and instead has Super Sonic flying rapidly across the screen multiple times, damaging anyone he hits; however, his height can still be adjusted.

Mario Kart 8 / Mario Kart 8 Deluxe
The artwork of Sonic from Mario & Sonic at the Olympic Winter Games is seen on the Mii Racing Suits screen of Mario Kart 8 and Mario Kart 8 Deluxe. Upon scanning the Sonic amiibo onto the NFC Touchpoint, a racing suit stylized after him will be accessible to the player; this suit can be used on the Mii.

Yoshi's Woolly World / Poochy & Yoshi's Woolly World
By tapping Sonic's amiibo into Yoshi's Woolly World and Poochy & Yoshi's Woolly World, the player will unlock a Yoshi appearance based off of Sonic, sporting blue skin with flesh-colored arms and chest, Sonic's shoes and gloves, and green eyes. Tapping in the amiibo will cause Yoshi to transform into this appearance instantly, although it can be switched to at the amiibo Hut as long as it has already been used.

Super Mario Maker
Sonic the Hedgehog appears as one of the Mystery Mushroom costumes available in Super Mario Maker. The costume can be unlocked by clearing 100-Mario Challenge on Expert difficulty or by tapping Sonic's amiibo onto the Wii U GamePad, and can only be used with the Super Mario Bros. style. The sprite used for Sonic is 16-bit, being based on his sprites in the original  game; this makes it the only costume in the game to not be 8-bit. Collecting the Mystery Mushroom giving the player this costume plays the 1-Up tune from the 1991 game Sonic the Hedgehog, and all of Sonic's sound effects are taken from the original games. Pressing causes Sonic to look up while playing the Ring-collecting sound. Finally, Sonic's "course clear" and "lose a life" fanfare are the course clear and game over fanfare, respectively, from Sonic the Hedgehog 3.

Profile
''The fastest hedgehog in the world, this little blue speed demon often gets going so fast, he appears to be just a whirling blur. He'll usually be found in front of any of the speed-based events in these Olympic Games, and will be very difficult to catch in any of the short-distance sprints.''

Palutena's Guidance

 * Pit: For being a hedgehog, Sonic really isn't very spiky, is he?
 * Viridi: Yeah, I've seen spikier. It's true that you're more likely to find him curled up in a cute, harmless ball.
 * Palutena: Not so harmless. That round shape lets him Spin Dash with ease.
 * Pit: I've changed my mind. He's entirely too spiky.
 * Viridi: Spin Dashes are hard to stop, though.
 * Palutena: Just keep your cool and don't lose focus. You can stop Spin Attacks using your Orbitars or Bow.
