Dagon

A 7 foot fishman sorcerer, Dagon is a freakish being with a lot of things about him being very come-and-go. He's a powerful sorcerer, but comically inept at times. He's a fish man, but he can't breathe underwater. He can open portals to The Underworld, but screams like a girl when he's hit and always seems a bit too eager to grovel for mercy. He seems to know more than the average cultist, but considers himself a tool and a perfect patsy for the cult. It's probably a mix of lying, cowardice, and self-esteem issues. And evil. He has at least a little evil in there.

Dagon's either a very clever monster or a very mutated mage, but he is covered in scales with stubby claws on his fingers and toes. He has a tall gnarled staff that he wields most of his magic with, and summons dark portals to the underworld that he apparently cannot reverse (or maybe just should not). He wears loose robes that show his fishy legs, arms, and face.

Story: Dagon appeared after capturing Basil in the museum, luring Jack and the kids there. He trapped Jack and Basil in a portal to the Underworld before cursing the kids and their monsters with the Curse of Banishment, meant to cast them into the Underworld as well but overexerting himself, merely cursing them to be banished should the Ur Monster be restored. He was beaten pretty soundly, as Razorface shredded most of his staff, Clanker set him ablaze, and Alexander gave him tormenting visions. When pressed, he quickly surrendered and explained what he, the cult, and Jack were up to before Jack sent back the postcards for the missions ahead.
