Sonic the Hedgehog is the main character of the series of the same name. He, along with Tails, Knuckles the Echidna and other supporting characters, are always out to stop Dr. Eggman from his evil plans. Sonic is a really fast character, as his name suggests. He also hates just standing around and doing nothing. When Sonic comes into possession of all the Chaos Emeralds, he will transform into a golden variant of himself, with much more powers than he normally would have. His best friend is the 8 year old Tails. In the game "Sonic Adventure" for the Sega Dreamcast, the golden Sonic can be seen flying with Tails, whilst Sonic has no mechanical means of flight, Tails is seen in his bi-plane alongside Sonic.
