Thunderbunny first appeared in fan publications. His first appearance in a title published by a major company came in Charlton Bullseye #6 (Mar. 1982), published by Charlton Comics, he made a subsequent appearance in #10 of that title as well.
The character then moved briefly to Archie Comics, appearing in Thunderbunny #1 as part of Red Circle Comics, a short-lived revival of the Archie Comics superhero characters, and also in Blue Ribbon Comics #13 (Oct.1984) (co-starring in a story also featuring the Fly, Shield, The Web, and the Jaguar), The All New Adventures of the Mighty Crusaders #7, and Pep Comics #393 (March 1984).
Thunderbunny then moved to WaRP Graphics for a 6-issue run (June 1985 - Feb. 1986), with an additional story in Warp Graphics Annual #1. Issues #7-12 were published by Apple Comics (Apr. 1986 - Nov. 1987).
Thunderbunny is the last survivor of an alien race of humanoid animals. The essence of this world's greatest hero is transferred into a special box shaped device and subtly presented to a young human boy named Bobby Caswell.
When Bobby placed his hands in two hand-shaped impressions on the box, the act caused a power transfer into his body and gave him the ability to transform into Thunderbunny. Although the powers, which include super strength and flight, are thrilling, Bobby finds the bunny form embarrassing. Furthermore, he learns to his consternation that the longer he stays in that form, the more difficult it is to form the essential mental image of his original form to change back. This combination of concerns make him most reluctant to use his superhero identity, but he still has numerous adventures in it.
