Circus performer Tiny Big's clown act was a flop, so he wandered the docks thinking of inspiration for a new act when he encountered some hoodlums and knocked over a cargo crate that allowed the Blackhawk Squadron to apprehend them. Inspired, he donned a miniature Blackhawk costume and attempted to help them stop The Yellow Raider. By the end of that adventure, he decided to ditch superheroics and instead make his new act being the Tom Thumb Blackhawk. While traveling with the Triple R Circus, he teams up with the heroes again to stop a fencing ring that is smuggling stolen goods in carnival prizes.
- This version of Tom Thumb Blackhawk, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
