Cartoon Action Hour

Cartoon Action Hour is an '80s action cartoon RPG. Inspiration for Cartoon Action Hour comes from Thundarr the Barbarian, He-Man, Thundercats, G. I. Joe, Jayce and the Wheeled Warriors, Transformers, and more. The first edition was co-written by Cynthia Celeste Miller and Eddy Webb. The heavily revamped second edition, Cartoon Action Hour Season 2, was written solely by Cynthia Celeste Miller.
