user summary: This source-book is a collection of material, adapted from the Thundarr the Barbarian cartoon, for use with Mutant Future. from the designer's introduction: Many readers of my blog have written to me, asking me to create a Thundarr the Barbarian supplement for Mutant Future. I obviously cannot (and will not) create anything “official” due to the copyrights and trademarks involved. However, as my gift to my blog’s readers and to the many fans of the show, I created this document—a simple compilation of all Thundarr Thursday posts that have appeared on The Savage AfterWorld in the past year. Gathered within is a cornucopia of Thundarr-related Mutant Future material including: Three new PC character classes! Eight nefarious NPCs! Eleven new devices! Twenty-nine (!) new creatures! And four adventures based on classic episodes! It is hoped that you will enjoy reading this collection of blog posts and—perhaps—working some Thundarr-inspired adventure into your Mutant Future campaign!
