Overview
Compare to Japan, in the west there has been many changes to Sonic the Hedgehog's character. This can be seen in the newer games where the dialog given to him in the Japanese and English releases tend to be different from one another. In the 90's he was so much more different, such as his favorite food being chili dogs, something that was never a part of the Japanese version till Sonic X and Sonic Advance 3.
This article will mainly describe the Sonic from the comics and cartoons.
DIC Entertainment
In all cartoons by DIC, he is a teenage chili dog loving hedgehog from Mobius thwarting Dr. Robotnik's ambitions. And again, with all DIC cartoons, he is voiced by Jaleel White, but his singing voice in Sonic Underground is done by Samuel Vincent.
