Laharl, the Overlord! (Need Help)

[Nihilarian]

This would be pretty difficult. Laharl shows up in most (if not all) Disgaea games and doesn't always have the same stats. And I think he can use most weapons (skills being tied to weapons in this game)

Just to be clear, are you looking for help in making a new class, or asking what classes would suit him best?

I'd say Dark Knight suits him the best out of all the classes. Maybe Holy Knight, if you think he's a good guy.
