From Green Ronin’s webstore:

Each Power Profile takes a look at a particular type of super-power in Mutants & Masterminds game terms, putting together the effects and modifiers from the Hero's Handbook to present different abilities associated with that power, from offensive and defensive to movement and utility. It also discusses different power descriptors and how they affect game play, as well as features and complications associated with the power. It's a ready-made guide to creating new heroes and villains for your M&M game!

Power Profile: Strength Powers

Sure, some may fly through the air, throw energy blasts from their hands or eyes, or play with thoughts like a puppet’s strings, but then there are those who are strong. Strength Powers look at the things you can do with sheer muscle power and physical strength far beyond that of any mere mortal. Who needs other powers when you can be the strongest there is? This product is for Mutants & Masterminds Third Edition.
