The original character description of Fatman/The Human Flying Saucer/Saucer-Man (apparently the only superhero with three separate identities!) sees Van Crawford, multimillionaire hobby-store owner and hobby expert (?), rescues a shape-shifting alien who has the ability to transform into a flying saucer. The grateful alien gives him a special potion to drink, which grants Van the same powers. He dons a colourful costume and becomes the superhero Fatman (??). Strange name and origin aside, I found the idea of a guy who can transform at will into an alien spaceship fascinating, so I had to try my own take on it.
In my version, Van is a successful but misanthropic comic-book and video shop owner with a passion for science-fiction and astronomy. One night, while stargazing with the local amateur astronomy club, he sees something fall from the sky. Having rushed to investigate, he is overwhelmed to see a disc-like craft, smoking in a crater. To his amazement, the craft begins to melt and dissolve, assuming the much smaller shape of a humanoid being. Van lifts the saucerman out of the flaming crater and away from the oncoming police and army sent to investigate. Once back in his apartment, the alien thanks Van and gifts him with a vile of nanotech solution, the very same that it uses to transform into its saucer-form. The alien departs, wishing Van good luck.
Van soon puts his powers to good use, reluctantly defending his planet from giant monsters, robots and supervillains as... the Saucer-Man!
