Pinky is the tritagonist of Animaniacs, the overall titular main protagonist of Pinky and the Brain and Pinky, and Elmyra and the Brain. He's a white lab mouse with an open-minded and empathetic personality, and he is the sidekick and in some ways opposite of Brain. Pinky often says random nonsense words and loves to have fun. Brain often claimed Pinky to be the main failure of his plans, although in actuality failures were sometimes not Pinky's fault.
