Sega's iconic mascot Sonic the Hedgehog, was first conceived by the pioneers of the Sonic Team: artist Naoto Oshima, designer Hirokazu Yasuhara and programmer Yuji Naka.

The first game in the franchise was released on June 23, 1991. He was created as a response to Nintendo's Mario, and to replace their current mascot, Alex Kidd.

Some early designs were an armadillo, a dog, a rabbit that could grab objects with its ears (which would later develop into Ristar) and a character resembling Theodore Roosevelt that later became Dr. Eggman. After several designs they came up with Sonic the Hedgehog although he was initially called 'Mr. Needlemouse'. He was colored blue to help players better identify with Sega.

Characteristics & AbilitiesEdit

Sonic resides in the Emerald Hill Zone on the Planet Mobius, which he steadfastly defends. Sonic is best known for his speed; he is able to run so fast that his legs blur and he can run across the surface of water. He is allegedly faster than the speed of sound, and in Sonic CD his pace is so incredible that it facilitates time travel.

Sonic can also roll into a ball to smash through objects, defeat enemies, and crack open discarded computer monitors to obtain bonuses and items. His spin charge attack allows him to build up power and speed. This physical speed also translates to mental alacrity (as he is constantly able to thwart his foes' machinations), and impatience (as when Sonic is left idle by the player for too long he taps his foot impatiently).

When Sonic collects all 7 Chaos Emeralds he transforms into ' Super Sonic' - a faster golden Hedgehog with invulnerability and the ability to fly. Sonic can also collect golden rings which are littered around Mobius' several zones. 50 rings will allow sonic to enter the bonus level which grants him the chance to reach a Chaos Emerald. An extension of this power is his ability to become 'Hyper Sonic', a being impervious to all damage save being crushed or falling into bottomless pits. This form is accessed when Sonic collects all 7 Super Emeralds in the Sonic 3 & Knuckles game. He also gains the ability to cause the screen to flash, killing all on-screen foes.

According to the Sonic the Hedgehog comic books, Sonic obta

super Sonic

ined his green eyes when he originally fought the monster Chaos. When jumping through Chaos, part of the monster was absorbed by Sonic, turning his eyes from black to green.

100 Rings grants Sonic an extra life. If Sonic is hit by an enemy he will drop all his rings, and has only a short amount of time to collect them before they fade away. If Sonic is hurt when he has no rings, he will lose a life and be dropped back to the latest checkpoint.



Sonic has a deep rooted bond with his pal and closest friend Miles Prowler aka Tails as a younger brother. Sonic is consequently joined by Tails in many of his adventures subsequent from Sonic 2. Tails has the ability of flight, and in Sonic 3 Tails can lift Sonic for short periods of time to access hard to reach areas.

Close FriendsEdit

As the female counterpart, a pink colored hedgehog by the name of Amy Rose was the solution for Sonic, He is constantly being chased Amy, who had no secret in hiding her admiration for him, professing her profound love with a devotion to marry him off as her wedded husband.

Friendly RivalryEdit

Despite getting off to a rocky start (having been tricked easily of the stolen Chaos Emeralds' captors), Knuckles the Echidna has earned the title as a close friend and is consistently a friendly rival to Sonic.


Sonic's nemesis is Dr. Ivo Robotnik (aka Dr. Eggman), an evil scientist who seeks to enslave the inhabitants of Mobius. Though clever as Robotnik may be, he is time after time thwarted by Sonic's interference with plans carried out throughout Sonic's adventures.

There are rare occasions in which Robotnik is akin sides with Sonic to unite their force against a larger threat stand between his own efforts. Such is the case when Robotnik takes heed of Biolizard's presence as an apocalyptic threat to the entire Earth when the creature takes on a crash land collision course towards the planet.

In Sonic Adventure, Sonic ridiculed and teased Robotnik of his round shape, taunting him with the name " Eggman". It began when Sonic had placed name on him for being a "Giant Egg", in which case Robotnik counter-responded that his full name is Dr. Ivo Robotnik. Neglecting the recent claims of Robotnik, Sonic goes on to reply, " Whatever, Eggman!", and so his name since that encounter has been been left as Eggman, rather than an alias.
