Mom

Mom is the owner and CEO of Mom's Friendly Robot Company. Her public face is that of a sweet, motherly old woman, but her personality in private is abrasive, abusive, bitter and in some cases, malevolent. Her public body is stereotypically motherly - fat and frail, usually in a rocking chair, but in private she takes off her fat-suit and is slim, usually sporting a skintight blue suit and tall black boots. Her bitterness may have been caused by her failed relationship with Professor Farnsworth. They briefly got back together on Mother's Day, but she broke it off when she discovered that, although the Professor's feelings had become genuine, their meeting was a ploy to get the controller to stop the robot rebellion. So they still hate. It is revealed in that Professor Farnsworth is the father of Igner, the youngest of Mom's three sons. Walt and Larry's paternity is still in question, however it's possible Mom's first husband, Dr. Ogden Wernstrom, is their father. Despite having been married before, Mom has claimed that Professor Farnsworth was "the only man I ever loved. "She apparently holds the trademark on the words "Mom", "Love" and "Screen Door". Mom owns 99.7% of her conglomerate company MomCorp. The remaining 0.3% is split evenly between her three sons Walt, Larry and Igner. She appears in under the identity "Momon" and eventually becomes a dragon that does battle with Fry, also a dragon.
