This book was inspired by Greater Than Games co-operative card-based board game, Sentinels of the Multiverse. Ostensibly, Sentinels is a comic-book themed card game, but its characters are so original and interesting that they span more genres than just superhero fiction. Mr. Fixer (realized as the Way of Repair) is a grease-monkey that fights with martial arts based on garage tools, and the Haka is an immortal tribal Maori warrior.
This book isn't intended to translate the entire card game to D&D, but it should give you a launching point for your own adventures with these colorful heroes. Enjoy, and have fun playing with the Sentinels!
