Ansgar Damian
A young man of 23 years with sapphire hair and a royal blue coat and a slightly-larger-than-average spider sword that he uses both hands with. The rocket launcher is an APEX-VII Spekter Launcher; it fires special ectoplasmic energy blasts that can destroy ghosts and demons quickly, and also allows for splash damage. He also carries a .45 quad-barrel Glock that fires spectral bullets similar to the rocket launcher, but without splash damage.
Not much is known about him beyond his passion for destroying otherworldly beings. This passion borders on necessity, but why isn't exactly known. The scuttlebutt is that his entire family was destroyed by demons and ghosts when he was 5 and he's out for revenge, but upon asking, he won't say anything. He's normally a pretty laid-back guy, but he takes his job seriously.
Strengths: Good with his weapons, particularly the pistol; he's deadly efficient against the abnormal.
Weaknesses: Prone to outbursts regarding his relationship with ghosts and whatnot (not good) and considers anyone he works with as allies only, or at most acquaintances.
