Sonic the Hedgehog (Adventures of Sonic the Hedgehog)

Personality
In this series, Sonic is depicted as a young rebellious teenager. While he can be loud and obnoxious, he still fiercely defends Mobians from anything untoward, including Dr Robotnik.

Despite the devious attitude he is given in the main show, during the Sonic Sez segments he is illustrated as a responsible role model for the innocence of Tails, often dealing advice to the fox when he gets into a difficult situation.

Abilities
Sonic can run at extremely fast speeds, assuming he is wearing his specially designed Hi-tops, which he uses to his advantage when fighting Robotnik. He is also capable of curling into a ball and performing a buzzsaw attack which can cut through most objects, though Robotnik has used various materials such as Nuclear forged steel and Diamondium laced metal to counter this ability.
