Marvel: Crisis Protocol – The Blob & Pyro adds two new mutants to this game system. Fred Dukes, known to many as the "Blob", has the superhuman ability to become virtually immovable at a whim while in touch with the earth. Joining him is St. John Allerdyce, more commonly known as Pyro. Allerdyce can shape fire, increasing or diminishing its heat, intensity, and size, making him a menacing addition to any team. Together, these characters supplement the Brotherhood of Mutants Affiliation with their mutant abilities and three Team Tactic cards that give them even more ways to work together with their teammates.
