Rouge is a Mobian bat, a professional thief, kind and affectionate with friends, and flirts a lot with Knuckles, though Knuckles can't tell the difference between hints and threats. She's peaceful and friendly, but with her wings, she can fly at incredible speeds.

Knuckles is a Mobian red echidna. He's very grumpy and bitter, though sometimes he is kind, but rarely. His favorite food is grapes. He's a bit dim, and his strength is so great that he can easily lift 10 tons.

Tails is a small fox with two tails that allow him to fly. He loves inventing things, even for others. His favorite food is mint—anything with mint in it. He doesn't like to fight; he's very peaceful and kind, and he's the smallest of them all.

Amy is a pink Mobian hedgehog. She is kind and very patient. She doesn't like being rushed or having a friend insulted. She is very peaceful, but when she is really angry, she takes out her Piko Piko Hammer. She likes to bake cakes or cookies and cook, especially being with friends.

Sonic is a blue Mobian hedgehog who is very fast, cheerful, sarcastic, and a joker. He doesn't care about much, which can be a bit irritating at times, but he's friendly. His favorite food is chili dogs, and he really likes running or doing anything that involves physical activity.
