They are the children of the atom, possibly the next step in human evolution. They are endowed by a quirk of the genetic code with powers and abilities beyond those of mortal men and women. They can be anyone, anywhere. They can be good or evil. They are a potential resource for the future and a potential threat for the present. They are respected, hated, loved, feared. They are mutants, and they are among us.

This campaign boxed set is the most complete reckoning to date of the mutant heroes of the MARVEL UNIVERSE™ as well as their mutant and non-mutant foes. Within these pages are complete histories and membership rosters of all the super-human teams. Archetypes of mutant hero groups allow you to fit your own mutant heroes into the MARVEL UNIVERSE.
