<P> The Brain (voiced by Maurice LaMarche) looks and sounds a little like Orson Welles . In "What Ever Happened to Baby Brain", Brain actually crosses paths with Welles (voiced by Jim Cummings), who is working as a busboy in a Hollywood restaurant; they find themselves inadvertently yelling in unison, "Things will be different when I take over the world!" In "Project B.R.A.I.N." Brain's name is the backronym for the eponymous project: "Biological Recombinant Algorithmic Intelligence Nexus". His tail is curly and bent--he often uses it to pick the lock of the cage--and his head is large and wide, housing his abnormally large brain . He is highly intelligent and develops complex plans for global domination using politics, cultural references, and his own inventions toward his goal . He seems coldly unemotional, speaking in a snarky deadpan . Nevertheless, Brain has a subtle sense of humor and has even fallen in love; with Trudie in the episode "The Third Mouse" and with Billie in "The World Can Wait". Due to his stature and megalomania, Brain has been compared to Don Quixote and a pop culture depiction of Napoleon Bonaparte . </P> <P> Brain sees his inevitable rise to power as good for the world, and not mere megalomania . In Wakko's Wish, he said to Pinky "We're on our way to fame, fortune and a world that's a better place for all ." Many of the Brain's plots had the endgame of winning over the people's hearts and having them make him their ruler . However, his motives are not pure . In one episode, Brain finds himself hypnotized by a psychologist he had planned to manipulate for one of his schemes, who turns out to be none other than Sigmund Freud . There Brain reveals that he originally lived with his parents in a tin can at the base of a tree in a large field . When he was young, ACME researchers captured Brain and took him from his home, and the last he saw of it was a picture of the world on the side of the can . Dr. Freud speculates that Brain's hunger to take over the world is misplaced, and that all he really wants is to go back home to his parents . According to the creators, Brain wants to take over the world not for the sake of being a dictator, like his rival Snowball, but because he believes that he could do a much better job of it than the people currently in charge . Brain has even helped save the world by doing everything in his power to prevent Snowball's evil schemes, knowing that a world under Snowball's rule would be the worst - case scenario . </P> <P> Pinky (voiced by Rob Paulsen) is another genetically modified mouse who shares the same cage as Brain at Acme Labs . Although intelligent in his own right, Pinky is an extremely unstable and hyperactive mouse . He has several verbal tics, such as "narf", "zort", "poit", and "troz" (the last of which he started saying after noticing it was "zort in the mirror"). Pinky's appearance is the complete opposite of Brain's--while Brain is short, has a crooked tail and pink eyes, and speaks in a deeper, more eloquent manner, Pinky has a straight tail, blue eyes, and a severe overbite, is taller than the Brain, and speaks in a higher pitched voice with a Cockney accent . Pinky's name was inadvertently given to him by Brain himself: when insulting the two scientists responsible for their gene splicing while talking to himself, Brain claimed the scientists had "less knowledge in both their heads than I do in my...pinky!" Pinky then responded with "Yes?", believing Brain was referring to him . </P> <P> Pinky is more open - minded, kinder, and happier than the Brain . Troubles never ruin his day, arguably because he is too scatter - brained to notice them . He steadfastly helps Brain toward world domination, even though Brain usually berates, belittles, and abuses him . Pinky actually seems to enjoy this, laughing after he is hit . He is obsessed with trivia, spending a lot of time watching television in the lab and following popular culture fads . Sometimes Pinky even finds non-rational solutions to problems . An entire episode (entitled "The Pinky P.O.V.") even shows a typical night of attempted world domination from his point of view, showing his thought process and how he comes to the strange, seemingly nonsensical responses to the Brain's famous question, "Are you pondering what I'm pondering?" Pinky often points out flaws in the Brain's plans, which the Brain consistently ignores . The issues Pinky brings up can ironically lead to the downfall of the given night's plot . </P>
