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: Speed Powers

Faster than the eye can see, perhaps able to outrace light itself: Speed Powers are all about moving and reacting fast. Zoom from one side of the world to another in the blink of an eye. Defy gravity, running up walls or across the surface of water. Even vibrate your body to pass through walls or travel across time and other dimensions! Accomplish a week's work in an instant, and have the villains in jail before they even realize you've moved. This product is for Mutants & Masterminds Third Edition.
