Brian's other favorite Sonic Riders character

My other favorite Sonic Riders character is: Super Sonic. I collect all gold emblems in Mission Mode to unlock him. I don't know what his type is, but it's hard to unlock him. His starting gear is Chaos Emerald in this game. I have to unlock 4 more characters, NiGHTS, AiAi, Ulala, and Super Sonic. I don't know what his favorite color is either. He's the best other Sonic Riders character ever!
