Fishmongrel is the chief henchman of the Codfather. He is an aquarian, a race of very unusual fish-like humanoids. Unlike his master, this creature lacks any charm. This monster is a cold-blooded killer.

Fish out of Water. This creature has never felt comfortable out of his natural environment. He doesn’t like living on the land or any of the local inhabitants. Fishmongrel longs to return to the aquarian homeland.

Nautical Network. Thugs, pirates, and other nefarious characters work for Fishmongrel. They follow orders obediently and don’t ask questions. Some disobedient henchmen have been known to disappear and wash up on shore a few days later.
