Ok, I guess I'd better introduce his buddies...
Tails: Sonic's 3-tailed
fox friend that he basically adopted early in his life... He's like a little brother to Sonic, and he'd do anything for him.
Knuckles: Sonic's relatively new friend. He
hasn't known Sonic as long as Tails, and still has his doubts about Sonic... but he's growing on him.
Amy: Er... I don't really know much about her...
more on that later...
Cream: WHOA... I never even knew about her until
about 3 days ago... I know NOTHING except that she's a rabbit.
Big the Cat: Basically a giant cuddly cat that likes
to fish.
Shadow: An evil Sonic, I believe...
Rogue: Shadow's sidekick?
Dr. Robotnik: Sonic's evil genius rival... always
making giant machines to rule the earth... or crush Sonic, whichever comes first...
