Tails.
He is always with Sonic and he does his best to help out.
He also manages the X-Tornado and fixes it when it's broken or needs repair.

According to a character poll conducted, the most popular character is Haibara Ai.
Team Sonic are the trio of Sonic, Tails and Knuckles which feature under that name in Sonic Heroes. Sonic is the speed character and presumably the leader, Tails is the flight member and Knuckles is the power character. This name should not be confused with Sonic Team, who make most of the games of the series.
I would have to say Dr. Eggman.
The most rare sonic toy is Henry the Hedgehog. He was meant to be Sonic's brother but the character proved unsuccessful and only appeared for a short time.
If you mean a sonic x episode, most likely not. Silver is just a game character in some of the sonic games
Sonic the hedgehog as he is their mascot.
