Appearance
OrGorilla in her youth as a marine.
Captain Gorilla's face really looks like, gorilla. He has big furry sideburns, certain noses that resemble people like gorillas. On his head he wears a standard Marine hat. He wore a suit that matched the cold climate island he was sent to investigate something.
