Brian's other favorite Sonic Riders character

My other favorite Sonic Riders character is: NiGHTS. She is a secret character in that game, too. She can also fly. I must unlock Mission Mode and clear all 100 missions to unlock her Starting Gear: Night Sky. I must unlock AiAi, Ulala, and NiGHTS to clear all 100 missions to unlock them and thier gear. She's the best other Sonic Riders character ever!
