John "Banana"

is one of the four Marines that are playable in the map Verrückt in Call of Duty: World at War's Zombies mode. He and his squadmates were part of the mission to rescue Peter McCain which failed, leading to 3 of the 4 soldiers to presmably be killed and one being captured and brainwashed. Oppenheimer and Bush discuss about him in the Call of Duty: Black Ops  terminal, describing him as insane after experiencing being attack by an undead Smokey, his feelings when killing his first zombies and his encounter with a Monkey Bomb. All of the information was left by him in pieces of paper and limericks.
