Mr. Gorilla

Mr. Gorilla/Sean is a hallucinated animal, that visits Fish on occasion. Mr. Gorilla was initially seen one night when Fish was taking heavy medications, and appeared in his door frame, menacingly hunched over looking at Fish while attempting to sleep in his Cal King bed. He was last seen helping Fish fight off a home intruder, Satan, so what can be assumed is that Mr. Gorilla is a good funny big man.
