There's a version with a maniac. As I already wrote, in the game Twisted Metal, Sweet Tooth's real name is Marcus Kane. But he had a split personality. And the second personality was called Needles. And who is Kits Kitsunka? SHE'S A HEDGEHOG! GET IT?! That's it.

I suggest two options: Neira or Kitsunka.
