The Uncanny Avengers Vol. 3 (2015-2018) #14

Plot

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's makes a deal with the devil. (Actually, The Hand, and they're way worse.)
