from the cover:
A Mutant Future adventure for 3-6 players using pre-gens of the TV show’s characters
from BEFORE PLAY BEGINS…:
In this adventure, it helps if the players have a passing knowledge of the Thundarr the Barbarian cartoon show from the mid- 1980s. (Show them an episode or two if you can!) They will be playing the roles of Thundarr, Ookla, and Princess Ariel during the course of the game, so having an idea of the characters and their individual tropes will go a long way toward capturing the feel of a Saturday morning action cartoon show. The pre-gens have role-playing tips to help players unfamiliar with the show.
The twist to this adventure is that, due to a dimensional breach, there are TWO teams made up of Thundarr, Ookla, and Princess Ariel. If you have 6 players, there should be two Thundarr PCs, two Ooklas, and two Ariels.
