Overview
Fatman's costume is green and yellow. He had a yellow flying saucer emblem on his chest. Fatman was fat and could change into a human flying saucer. His comic ran for only three issues and was published by Lightning Comics, an almost equally short lived company. Fatman comics were produced in small numbers and are considered valuable because of Beck's artwork and their rarity.
Van Crawford became Fatman after coming to the aid of an alien flying saucer. The saucer itself turned out to be a shapeshifting alien, which rewarded Crawford by giving him a chocolate drink with the ability to transform him into a human flying saucer. Being a wealthy man, like many superheroes of the era, Crawford decided to use this new found power to become a superhero.
