You cant use the Picture, Prince (Althought you can be a Prince from any race) and any techniques that Laharl has. I played the games so if I see anything from the game your stuff shall be unaccepted. Also personality needs to be longer, especially looks.
Also You didn't really follow the template. The reason why you can't use Prince Laharl it's because the people running this site might get sued (We gotta go to court with the people that invented Disgaea, then if we lose our case we pay a lot of money.) which we probably don't have.
So just copy/paste the wanted template, post a new thread, paste it, fill it out without any pictures of Prince Laharl or any other Characters (I recommend Photobucket and search anime guy, girl, male, human, god etc...)
If I see you didn't follow the template or did very poorly in a couple of places then your character shall not get accepted.
