The New Teen Titans, Vol. 1 #14A

Revolution
Changeling and the female Titans rejoin their teammates, and Steve Dayton, recovering his Mento uniform, proves to be a brainwashed pawn of Madame Rouge and General ZahI. Mento attacks the Titans until overcome by Raven through an illusion. The Titans then trail Madame Rouge, General Zahl, and the villains’ now-airborne headquarters to the island nation of Zandla, which the evildoers attack. The other Titans are defeated and captured during the battle, while Changeling, separated from them, is taken prisoner by a revived Brotherhood of Evil led by the Brain and Monsieur Mallah, former archenemies of the Doom Patrol.
