Ability type


Sonic the Hedgehog (Japanese: ソニック・ザ・ヘッジホッグ Sonikku za Hejjihoggu) is a supersonic hedgehog that can move faster than the speed of sound (765 mph, which is faster than Mach 1), with lightning reflexes to match (hence the name Sonic) and loves adventure. He acknowledges the fact that the Earth is just as cool and blue as he is. He is 15 years old, stands at 100 centimeters (3 ft 3 in), weighs 35 kilograms (77 lbs) and was born on Christmas Island. Artist Naoto Ōshima, designer Hirokazu Yasuhara and programmer Yuji Naka are generally credited with the creation of the character, a blue-furred, blue and-peach-skinned, green-eyed, anthropomorphic African pygmy hedgehog, who has the ability to move faster than the speed of sound and possesses the ability curl up into a ball (like a regular hedgehog), primarily to attack enemies. This is a major part of the gameplay of the series.

Concept and creationEdit

In April 1990, Sega requested a game capable of selling over one million copies, a character who could compete against Nintendo's Mario, and a character to replace Alex Kidd as the company's mascot. Several character designs were submitted by its AM8 research & development department, including an armadillo (who was later developed into Mighty the Armadillo), a dog, an over-sized Theodore Roosevelt in pajamas (which would later be the basis of Doctor Eggman's design), and a rabbit (intended to use its extendable ears to collect objects; these aspects were later incorporated into Ristar, and were later incorporated into Sonic's Werehog transformation). Eventually, a hedgehog, whose color was based on the SEGA logo and his personality, on the other hand, was directly inspired by future-President Bill Clinton, who Ohshima felt embodied a modern sensibility of wanting to get things done right away, righting wrongs as they presented themselves instead of letting them linger initially codenamed "Mr. Needlemouse", was chosen as the new mascot.

A group of fifteen started working on Sonic the Hedgehog and renamed themselves Sonic Team. The game's soundtrack was composed by Masato Nakamura of the band Dreams Come True. Sega sponsored the group's "Wonder 3" tour, painting Sonic on the tour bus, distributing pamphlets advertising the game, and having footage of the game broadcast above stage prior to its release.

Sonic's precise age, weight, height and other physical characteristics vary depending on the continuity in which he appears and the style in which he is drawn. In the video games, Sonic's original design by Naoto Ōshima was quite short and childlike (perhaps because he was 10 years old at the time of debut), with short spiky hair, a round body, one spike in his back, and no visible irises. Artwork featuring this design and drawn by Akira Watanabe was displayed on the package artwork for Sonic the Hedgehog, and most subsequent Sonic video games featured similar designs. Beginning with Sonic Adventure in 1998, Sonic was redesigned by Yuji Uekawa as a 15-year-old, taller character with longer legs and a less spherical body, longer and more drooping spiky hair, two spikes in his back, and emerald-green-colored eyes. Further subtle changes to the character's design have been made in subsequent games. Spin-off media such as comics and animes have featured variations on all these video game designs, with restrictions set by the standardized model sheets.


The reason Sonic is blue in color is because so that he can represent SEGA's logo which is blue. Also, the color blue symbolizes "peace", which Yuji Naka felt that the word "peace" describes Sonic's character very well.


Early lifeEdit

Nothing is known about Sonic's early life. It is unknown who his family is or if he has one, nor is it known how Sonic gained his trademark speed. All that is known is that Sonic was born on Christmas Island. It is not even known how he and Dr. Eggman became enemies.

In the comicsEdit

A comic which featured Mario, Sonic, and the rest. The only American comic published by Super Jump Punch! Comics, Super Smash Brothers is based on the settings established by earlier animated TV series, the CBS Super Smash Brothers (SatMS) anime respectively.

In the animeEdit

The Super Jump Punch continuity was based heavily on the Super Smash Brothers anime; it was far more dark and brooding than Go! showing Bowser and Eggman as fearsome dictators controlling Mubix and Mario, Sonic and their Power Fighter friends battle to take back their planet. Sonic was voiced by Roger Craig Smith in the United States, where the anime was marketed as Super Smash Brothers which stars everyone`s favorite plumber and hedgehog as the main characters.


  • Originally Sonic was supposed to have visible fangs in the Japanese artwork, but they were removed when he was given a more Americanized design for the US artwork in order to "soften him up" a bit. Although he does have fangs they are only visible when he opens his mouth (this can mostly be seen in Dreamcast titles like Sonic Adventure and Sonic Shuffle, but stopped being as noticeable after Sonic Adventure 2). Before, his fangs were supposed to be visible even when the mouth is closed.
  • Sonic has tied for 10th best selling series with Nintendo's Super Mario Brothers.
  • Sonic is featured in the McDonalds commercial along with Mario, Lugia, Ho-Oh, Mega Man, Bomberman, etc.
  • Sonic's age has always been a tricky one to pinpoint. According to the Sonic Technical Files, it says he is 18, "but it's kinda hard to tell." In a video for those who preordered Sonic the Hedgehog 3 in Japan, Sonic's age was listed as being "15-16." Once Sonic Jam was released, it looked like it was solidified at 16, but with the Sonic Adventure era, his age is now listed as 15.
  • Sonic also made a cameo in Nintendo: Inflation Go! FA #7, where he plays hide and seek with Tails, Knuckles, Cream, and Amy.
