The Jack of Diamonds.

No one knows for sure where Fishhook and his kind came from or -what- he is for that matter. Hell, how can we even sure that 'Fishhook' is his real name to begin with and not just some snazzy card-slang based name to go with the red diamond pattern on his face?

You know what? None of that is actually important, come to think of it. What is important is that we're all clear that he's just some cigar-chomping, fatpants wearing, pasty mobster thing monster.

Oh, and he's into some girl named Kari or something.
