Really Really BIg Man, Big Man or RRBM for short, is an extremely large and strong insectoid superhero who stands 6' 6" tall and wears a big red costume and a purple mask. In most episodes that revolve around him, he shows incredible, but uncontrollable strength.
His superpowers include flight, magic chest hairs to make rapscallions see the past, nipples that allow people to see their future (by attaching them to the eyeballs), and super strength. His alter-ego is a transvestite office worker named "Lois Lane" (a parody of Superman). His catchphrase is "Gaze into my nipples of the future!".
He is about 36 years old and is voiced by Tom Kenny.
