The twins make their first appearance in "Titans East" as Titans East members, a Teen Titans team set up in Steel City for the purpose of hunting down Brother Blood. Cyborg arrives to help the team build their tower, but Brother Blood attacks with his Cyborg-drones and defeats the Titans. Unbeknownst to Cyborg, Blood places all the members of the Titans East team under mind control and later forces them to attack Cyborg. The original Titans arrive following Cyborg's S.O.S., and Cyborg battles Blood while Titans West battles Titans East. With Brother Blood's defeat, Titans East is freed. Más y Menos also develop a crush on Starfire when they meet her, and both twins fight for her affection (the only time where they do not cooperate).
