The Brain is a main enemy of the Teen Titans and the leader of the Brotherhood of Evil. He makes his debut in "Brian". He is also the archenemy of Beast Boy. He is voiced by Scott Menville.


The Titans were locked up in a cell with electric bars and The Brain arrives to check on them. Robin was confident that they will escape anyhow since Brain took away their powers for his secret project in development. When Beast Boy yells at him as Brian, the Brain corrects him and leaves. Robin decides to organize another escape plan which involves Beast Boy, but eventually it fails as Starfire mentions that every time they are trying to escape, they get tortured by electricity.

Back at the Tower, during the party, when Super Robin sees the distress signal, he figures that the Titans were captured and orders the other buddies to go in action. The Little Buddies arrive at The Brain's HQ building on the roof where Super Robin tries to fight against Monsieur Mallah, but fails and the rest of the buddies get captured as well. On the other hand, the Titans are used to living in their cell, except for Robin who tries to reach for the command panel and without any knowledge of what's inside of it, his arm gets crushed resulting him to scream in pain, getting the Brain's attention and tortures the Titans again. The Little Buddies finally team up and defeat Mallah, as they reached the main laboratory after fighting off the security guards. The Titans are still waiting for a miracle to escape, while Robin is digging for a tunnel with a spoon. Eventually, the Little Buddies arrive to rescue them but their moment is interrupted by the Brain whom his project B.R.I.A.N is complete by placing his head in a giant robot filled with Titans' powers. Beast Boy now corrects his misspelling for being called Brian and not B.R.A.I.N.

The Little Buddies are fighting against him but they all get defeated except for Birdarang who transforms himself into a enhanced fighter after Beat Box tried to defend him but got hit. While fighting, he finally throws his head as a boomerang, breaks through the Brain's power cells and kicks his head out of the robot which causes the robot to fall. All the powers are free and return back to its own Titan which eventually they escaped at last. As they reach for their fellow Beat Box laid down on the floor, Cyborg places some new batteries which it turns on again with music this time. The Titans and Little Buddies are celebrating their victory, except for Robin who was left behind in the cell still digging with his spoon.

The Brain re-appeared in the episode "A Farce", where he served as judge in the trial of the Teen Titans. At the end of the episode, the Brain declared that the Titans were found guilty.

In "40%, 40%, 20%", the Titans, except for Cyborg, were captured by the Brain. He had to use Night Begins to Shine to free them.

In "That's What's Up!", he decided to enact his revenge against The Doom Patrol who didn't gain a permit for their clambake by exploiting the laws of the City Council and humiliated them for being degenerates. He even managed to mutate the clams so that he could conquer Codsville. However, with the teamwork of the Doom Patrol, his scheme was foiled and he was forced to serve the guests during the clambake.

In "Rain on Your Wedding Day", he had ordered his soldiers to build a rain-ray so that he could flood Jump City. Contrary to his expectation, his rain-ray ended up replenishing the city and making every citizen overjoyed. He then decided to give up villainy until the Titans except Robin began to misuse "literally", much to he and Robin's chagrin.


The Brain has been a wicked and conniving individual. He knows exactly how to exploit the law such as using his position as judge to declare the Titans' death penalty and to try preventing the Doom Patrol from intervening with his clam mutation by having them arrested for not having a permit. He is also well-prepared, always having Mallah and his soldiers on guard to avoid anyone from attacking him ahead, or even once having Terra as a double-crosser just to trap the girls.

Nonetheless, his conceit is one of his flaws, which often results in his humiliating defeats.

Power and Abilities

Being limited to only having a brain, The Brain is not a threat physically, but mentally he is a very formidable.

  • Super Intelligence: The Brain is arguably one of the smartest characters in the series, being the first villain to successfully capture the Teen Titans off screen by unknown means. He also knows how to exploit loopholes to abuse the law to accomplish what he wants.
  • Master Technician: He is able to organize and use his strategic plans very well.
  • Leadership: He is the head of The Brotherhood of Evil.
  • PROJECT B.R.I.A.N.: Is a super invention of The Brain that uses machinery along with all the powers of the Teen Titans outside of Robin. With The Brain's intellect and the brawn of the robot, The Brain becomes an even bigger threat, easily being able to handle all of "The Little Buddies" until Birdarang's transformation.

The Brain in his ultimate form.

  • Chemistry manipulation: He knows how to use chemicals to mutate and power up an originally innocuous creature.
