9. Johnny Karaoke

Look, everyone knows about Marvel's Japanese gangs. You can't go twenty pages without running into Wolverine hacking up some Yakuza or Daredevil fighting The Hand. But no one talks about the DC Yakuza!

Specifically the Geisha Girls. Specifically the LEADER of the Geisha Girls. His name is Johnny. Johnny Karaoke. He carries around a sword cane. That he sings into. He likes to sing and stab people and shoot them. That's the greatest thing of all time.

Why have we seen four movies featuring The Joker but zero about this glorious man of honor? I mean, aside from the fact that he died in the second issue he ever appeared in. Seriously. First appearance: Batman #660. Death: Batman #661. Short tenure there, sweetheart.

In trying to do additional research on the dude, I discovered a few other things. He attended UCLA and majored in business administration. That's neat. Not far from me, either. And that, ladies and gentlemen, is how you get a paragraph of content out of a dude who only ever appeared twice. Impressive, right?
