I rather like 'Sarcastic Knight'. I can think of a couple of fictional characters who fit that description.

As for the Crazy Wizard name, well, it's half right... *g*

I'm wondering how Irate Leader will square up to Fearless Dominator, though.

And you know, Quiet Samurai rocks.

Not sure about Mighty Demon. I think my Amazing Mastermind will defeat it on the basis that demons don't tend to be that bright (unlike devils, of course).
