"A Failed Experiment"
*Civil War II Tie-In! The Unity Squad's mutants go rogue, no pun intended, as they search for a solution to the Terrigen Mist problem that's been killing their brethren. Steve Rogers makes a shocking decision, and the Unity Squad will never be the same! Doctor Voodoo's brother makes a deal with the devil. (Actually, The Hand, and they're way worse.) *Source: marvel.com
