However, unknown to both groups, Control Freak zapped himself into the tower, seeking revenge on the Teen Titans, only to find them gone.

Robin, Starfire, Beast Boy, Raven, and Cyborg were on a mission trying to stop the Brotherhood of Evil, and because of that, they couldn't watch over Jump City, so Cyborg asked Titans East to look after the city for them. After coming back to their senses, Más y Menos immediately developed a crush on Starfire, which endangered their brothers' bond a bit. Blood managed to capture the entire lot, but was finally defeated by Cyborg and jailed. The Teen Titans, summoned by Cyborg, interfered and battled the brainwashed Titans East. Without the asisstance of their teammates, the twins were captured and, subjected to Blood's mind control, became his new 'students.' In order to augment his mind control and to find out what had enabled Cyborg to resist his mental powers, Blood decided to convert the Titans East into cyborgs. Más y Menos aided in the team's first takedown of the villain Steamroller, but when Brother Blood and his robot troopers attacked the tower soon afterwards, the Titans East panicked and split up, each fending for himself, herself, or (in the twins' case) themselves. Cyborg, who had originally come from Jump City to help outfit their tower, decided to give them a hand in getting more organized as a team. Initially, the twins were - by necessity - the only Titans East members who worked as a team, but even then they still got into the way of the others or were hindered themelves. They are first seen in the episode Titans East, where they were helping Speedy, Aqualad, and Bumblebee build the Titans East tower. Both are about 11 or 12 years old and come from Guatemala, and even though they had not learned to speak English at the time they came to America, they are perfectly able to understand it. How the twins came to the attention and enlistment into the group which would become the Titans East remains unknown.
