Keepers

From publisher blurb: The Manual of Mutants & Monsters Keepers for Mutants & Masterminds have Come to Collect This release of The Manual of Mutants & Monsters provides game stats on the Keepers, a "race" of mysterious robots that scour the universe to ruthlessly take and collect samples of other species, both sentient and otherwise. No one knows why they do this or if they serve some greater cause or master, but every civilization that has ever encountered these collectors knows to fear the fate they bring. This product includes game statistics for the Keepers and their massive Ark spaceships, as well as ideas regarding how to introduce it to your game. Can your heroes stop them?
