Smite villains with power swords. Transform into mighty vehicles. Combat whole groups of evildoers. And do it all in your favorite Underoos. Cartoon Action Hour is two books in one: a complete rules system that allows you to play in any 80's-style cartoon action show and a sourcebook for players and GMs to play in the ready-to-go series, "Warriors of the Cosmos". Retro-toons are hot and playing them is cool. Underoos not included.
