Sonic

Sonic the Hedgehog is the titular protagonist of the Sonic the Hedgehog series of games. He is a blue, anthropomorphic hedgehog best known for his super speed and ability to spindash. Sonic was created as the result of Sega's attempt to create a mascot character to rival Nintendo's Mario. Sonic has since risen to be one of the most famous and recognizable video game characters. Initially, Sonic's design was much simpler with no irises and a short, stubby body. This was changed to look more mature and appeal to older players, which included the introduction of green eyes.

Biography
Not much is known about Sonic's in game history. Sonic is a famous hero in his world (often referred to as earth or Sonic's World), and often must protect it from Dr. Eggman and other threats.

Sonic's best friend is Tails, a two tailed fox. Sonic first met Tails on West Side Island, in which Tails followed Sonic. At first Sonic was unimpressed, but Tails showed his determination, Sonic began to grow fond of him. When Dr. Eggman attacked West Side Island, Tails offered up his help to Sonic. This lead to a close relationship between Sonic and Tails, to the point that Sonic views Tails as a younger brother.

Super Sonic
Super Sonic is a state Sonic reaches by harnessing the power of the Chaos Emeralds. First appearing in Sonic the Hedgehog 2, Super Sonic can be achieved by collecting all seven Chaos Emeralds. Sonic will stay in his super form for as long as he has rings. Since its first appearance, Super Sonic has become even more important to the series, being a sort of trump card Sonic uses against the most powerful of his opponents.

In Sonic the Comic, Super Sonic is portrayed as an uncontrollable evil state Sonic enters after exposure to chaos energy, and occasionally intense stress. Sonic must fight for control during this state, as his newfound sadistic nature and evil tendencies can be a danger for all those around. This version is sometimes referred to as Fleetway Super Sonic in order to differentiate from the game versions.

Classic Sonic
Classic Sonic is the name used to refer to Sonic's original design. Although originally just an iteration of Sonic, Classic Sonic has since become his own character. In Sonic Generations, Classic Sonic is portrayed as a past version of Sonic from his younger days. After being sent so the White Space by the Time Eater, Classic Sonic meets up with modern Tails. Classic Sonic would later meet up with Sonic in a fight with Dr. Eggman, where he would also reunite with Classic Tails.

In Sonic Forces, Classic Sonic once again appears in the modern world through a warp created by the Phantom Ruby. After appearing, Classic Sonic saves Tails from a Chaos replica created by Infinite.
