The Terrigenocide Storyline begins when Dr. Hank McCoy — aka Beast — discovers that the Terrigen mists, used by Inhumans to activate their mutation, breaks down mutant DNA. He also discovers that ISO-8, used to power up Champions, and which is immensely prevalent in the Battlerealm, only increases the speed at which the breakdown occurs. McCoy states that if something isn't done soon, it could spell tragedy to all mutants.[1]
