Brain is a character and one of the two main protagonists from the series Pinky and the Brain. The show, which aired from 1995 to 1998, follows the adventures of two genetically enhanced laboratory mice who embark on a quest to take over the world. Brain is a small, white mouse with large ears, pink eyes, and a pronounced forehead. He is characterized by his high intelligence, his ambition, and his tendency to speak in a sophisticated, formal manner. He is often portrayed as the more serious and practical of the two mice, and he is known for his catchphrase, "Are you pondering what I'm pondering?" Throughout the series, Brain and his partner, Pinky, come up with elaborate schemes to try to take over the world, but their plans are always foiled by their own incompetence or by outside forces. Despite their repeated failures, Brain remains determined to achieve his goal and often comes up with new plans and strategies. Despite his intense focus on taking over the world, Brain is also known for his soft spot for Pinky. He often takes care of Pinky and tries to protect him from harm, despite Pinky's frequent mistakes and silly behavior.
