One of if not the last of my characters.
Melodie "Melody", is nicknamed Mel. She's not the fighting type. That actually goes to her advantage considering she is the last of her species.

Originally the fiance of Jet, she just ended up hating his guts, even if Jet has feelings for Melodie and still has them for her. She used to be best friends with Wave... Until she found out Wave had interest in Jet and tried to talk Wave out of it. Let's just say Wave started throwing her wrenches at Melodie at the end.

She left the Babylonians the moment wrenches started flying, which was before the events of the first Sonic Riderz, if Mel would have still been there, she'd have advised Jet against working with Eggman. When she left, both her and Wave were crying. It took longer for Melodie to get over the loss of her friend than Wave, because Wave wasn't alone.
