Sonic

Sonic the Hedgehog is the main protagonist of the Sonic the Hedgehog series and Sega's mascot. He is a 20 year old, blue, anthropomorphic hedgehog, and is a laid-back and cool-headed character, meant to symbolize peace. Like his name and species would imply, Sonic can move as faster than the speed of sound, has lightning reflexes to match (hence the name: Sonic), and can curl up into a ball (like a regular hedgehog), primarily to attack enemies. These are the distinguishing traits that were used to make his character and world-famous video games.

In the Past, Sonic and Blaze are teamed up to help combat the Dark Spawns at the Battle of Central plaza.They find the hero/heroine in the middle of the battlefield as he/she wakes up from Fire's meddling with Sonic's time travel experiment. He and Blaze teach the Hero/Heroine about basic combat when they run into some Dark Spawns and a Dragodark. They leave to help out the other characters fighting in the battle while the hero goes to help out.After the City plaza battle it is unknown what happened to Sonic, thus, he is presumed dead.

The Future
In the Future, Sonic is in Central City (Past), serving as one of the four Guides that players can choose to work for. He is constantly lending a hand in the fight against Darkness and his minions, whether he is fighting, helping his Father Sonic create his satellite to survey Planet Darkness, or cleaning up the Space Port in order to take the war directly to the Planet. He is also unaware of Fire's crush on him who thinks he's "dreamy", although her attempts to get Sonic to notice her proved unsuccessful.
