Jack Biceps, "cast in the role of the All-American boy," is a young man living in Gothamville, who "detests the good guys in our culture." One of the heroes he hates is Aunt Man. Jack finds the recipe for a potion to turn him into a 'boy fiend', but while his friends look on, the potion fails. Following the failure, he disappears into his garage to assemble a Highro-Gyro from a crate he'd ordered previously. The Highro Gyro is a flying machine of strange appearance. Fully costumed in a domino mask, white dress shirt with black bow-tie, a blue cape and matching vest with an "S" symbol embellished on it, he sets out to create some villainy.
