Sonic

Sonic the Hedgehog is the eponymous main protagonist of the Sonic the Hedgehog series of video games. He has been Sega Corporation's mascot since June 23, 1991. 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. However, he is also prone to making rash decisions and dislikes being near water because he can't swim.

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 in 2010, Roger Craig Smith currently provides the English voice of Sonic. Sonic is a Nintendo Character

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. Sonic's first game for a Nintendo system was an enhanced port of Sonic Adventure 2 for the Nintendo GameCube, titled Sonic Adventure 2: Battle.

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 blue life jacket during the swimming events, since he can't swim. He still moves quite fast in water too.

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 all of the snow spirits to prevent any snowfall. Sonic and Mario team up in order to ruin Bowser and Dr. Eggman's plans to ruin the Olympics 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 just arriving at London for the Olympic Games. Not long after the two arrive, fog starts rolling in, though the fog is red. 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. As it turns out, they mistaken 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 and to 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 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.

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 neutral 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 a remix of the "Act clear" theme from Sonic the Hedgehog 3 and most Sonic games after that.

The Subspace Emissary
Sonic does not appear in the Subspace Emissary until the very end, after The Great Maze, making it a surprise appearance. As when 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 dashing 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, are 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 / Wii U. This time, however, he is available from the start. He is also now voiced by Roger Craig Smith in English instead of Jason Griffith. He is also now voiced by a different voice actor in different regions (e.g., he has a French voice in France). 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 change is that his down smash from the previous game (a back and forth Spin Dash) has been replaced with a split-kick. 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.

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

Yoshi's Woolly World
By tapping Sonic's amiibo into Yoshi's Woolly World, Yoshi will transform into an appearance based off of Sonic, sporting blue skin with flesh-colored arms and chest, Sonic's shoes and gloves, and green eyes.

Super Mario Maker
Sonic the Hedgehog appears as one of the costumes available in Super Mario Maker. The costume can be unlocked by playing 100-Mario Challenge 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 Sega Genesis / Mega Drive Sonic the Hedgehog games. 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.''

Profile
''Sonic the Hedgehog is a blue hedgehog that moves at Sonic speed who joins Mario as they go head-to-head at the Olympic Winter Games! Armed with his signature attitude and Spin Dash ability on the Wii and DS, and Jump Dash ability on the DS, Sonic brings a new level of competition to the Olympic Winter Games as his team goes for gold in Vancouver!''

Snake's codec

 * Snake: ...
 * Otacon: Snake, what is it?

 * Otacon: ...? Oh, you mean Sonic The Hedgehog? But everyone loves Sonic. He's a big star. Do you have any idea how excited people are that he's here in Brawl?
 * Snake: Yeah, yeah, I know, but there's something about him I just don't like.
 * Otacon: But...why? You must have some kind of reason.
 * Snake: ...Nope, just don't like him.

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.

amiibo

 * Sonic the Hedgehog is the fastest hero in the world, famous for his supersonic speed, iconic blue spikes and red shoes.
