So, in other words, he should mesh really well with Lunatic who is...pretty much the same way.

And yes, he is! He's a night-lifer, too! (Because he leads a double life, sigh.) Dispensing his idea of justice is a lot easier by night, especially as that's when a lot of criminals tend to come out. Right now he mostly sticks to Heropa, but he's not incapable of making appearances in the other cities, either.
