She was once a carefree girl on Mobius X who enjoyed girly things. She had a crush on evil sonic at the time. One night she attended a rock concert and met Evil Sonic (Scourge). They sort of fell in love but scourge pushes her away often and being the self centred jerk he is, often mistreats her. Their relationship is similar to Harley Quinn and The Joker. As a result of a broken-toxic relationship she becomes very spiteful, cold, twisted and aggressive. One day she finds a portal to Regular Sonics World where she encounters the Freedom Fighters of that world including her doppelgänger and arch-nemesis Amy Rose, whom she absolutely detests. She is very much the polar opposite of Amy Rose in every way, even though she is technically still an Amy. Deep down she’s hurting and broken-hearted. She’s jealous of any attention Amy gets from Sonic. Sonic feels kinda sorry for her and tries to get through to her.
