She's a cloning experiment. Not gone horribly wrong physically, but mentally she's pretty insane. Cruel, mean, a biter, and other stuffs, she's the worst characteristics of her "parents" (Mali and Zim). I blame her being made in the microwave for her pissiness. Anyway, she hates you, and you'll get a bite. Oh yeah, she's a lycanthrope too, so when she bites you, you thank your lucky stars she's not a Wererat or Werewolf. Those are very contagious, she's a Werecat, much harder to catch, but tell that to Dib...
