An obsolete robot maid, Tetsuko was created in 1982 at the King's Idea Laboratory. She lives with and works for Milk. Tetsuko is a more conservative character, the only occasional voice of reason on the show when she is questioning Milk's greedy, immoral or random decisions. She yearns for a stable traditional family life, which the humans around her do not even consider. Milk often calls her a piece of junk and Tetsuko is torn between loving Dr. Eyepatch (her "daddy") and being disappointed in him when he insults her or offers to replace her. She has the ability to generate a fart ("Tetsuko's gas") that could even kill a raging bear. The only character that brings out Tetsuko's aggressive side is Robodog whom she hates. They are in a constant conflict over Milk's affection, much to Milk's amusement.
