Pinky, are you pondering what I'm pondering?
~ Brain
The same thing we do every night, Pinky. Try to take over the world!
~ Brain

The Brain is the main antagonist of Animaniacs, one of the titular protagonists of Pinky and the Brain and of Pinky, Elmyra & the Brain, and a cameo character in Freakazoid!. He has an oversized brain, and is very knowledgeable. However, his attempts to conquer the world always fail. But the Brain doesn't let that bring him down, and by next night he will have a new trick up his sleeve.

He is voiced by Maurice LaMarche, who also voices Vincent Van Ghoul, Chancellor Neighsay, Inspector Gadget and Mr. Big.


Brain is a genius with a calm and overconfident personality. He almost never loses his cool, even when Pinky commits stupid errors that mess his plans completely (though he does often display clear annoyance). He also seems to be egocentric.

Despite his plans, he truly believes that he can make the world a better place, will never resort to murder to accomplish his goals and deep down he does care about Pinky. There are also some world domination plans even he won't attempt as they are sick even to him: for instance, he was unwilling to use a plan involving selling cigarettes to children.

Brain's good intentions are highlighted with his rival called Snowball, a hamster who also planned to conquer the world, but who is far more evil and cruel. Brain is disgusted by Snowball's methods and will stop at nothing to prevent him from taking over the world.


Both Brain and Pinky are laboratory mice who underwent an experiment to make them rational. The experiment had different results on each of them, turning Brain into a super genius, while Pinky also becomes sentient but incredibly stupid. Brain then decided he would use his superior knowledge to take over the world and make it a better place using his intellect. He convinced Pinky to aid him in his plans, and the two of them try a new plan to achieve world domination every night.
