With the Mutants & Masterminds rules you can create virtually any power you can imagine, but where to start? Power Profiles answers the question, "How do I create...?" for hundreds of different powers and dozens of different themes. Now you can "shop" through a catalog of pre-created power concepts looking for just the right one to suit the hero or villain you want to create. In this book you'll find over three dozen different Power Profiles, arranged according to theme, from Cold and Fire Powers to Mental and Meta Powers. Each profile features a look at the theme's descriptors and mechanics, important game system effects, and a selection of offensive, defensive, movement, and utility powers. That's over 400 different powers in one book! You'll also find some useful power variants, expanded power extras and flaws, and optional rules for use with your Mutants & Masterminds games, and some guidance on creating and handling more complex or unusual power concepts. With Power Profiles, your imagination truly is the only limit on your power to create!
