Damien was refused entry into the League of Evil Exes, but is available immediately after their defeat for a minimal fee. So, like, if you REALLY want to get Ramona you gotta get through him, too.
No one knows where he's spent recent years, but rumor has it he's paid his time. His fighting style involves a giant pair of Combat Scissors that are so powerful, he can perforate time and space with them. He refers to this technique as 'plot holing'.
