Ah. He's basically a demon who goes around getting rid of other paranormal/ things of myth or recruiting them to the Bureau of Paranormal Research and Defense, BPRD for short. He's best friends with a humanoid fish man named Abraham "Abe" Sapien, who possesses a unique frontal lobe that allows him to sense emotions of others along with information, and Elizabeth "Liz" Sherman, a pyrokinetic.
