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. As such, their conflict continues.

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.

Personality
In public Mom appears to be a sweet and motherly old woman. However behind this facade is an evil, bitter and sometimes maniacal woman, who wants to take over the world. She is often abusive to her sons, slapping them regularly and also says that robots made her "sick to my ass" even though her company makes them. Mom was once in love with Hubert Farnsworth but breaking up with him was probably what caused her to become such a bitter woman. However it's quite possible that she'd been evil before their relationship ended. Mom also often calls people insulting names.

Despite her claim that Hubert Farnsworth was the only man she'd ever loved, she has been seen in a relationship with Hubert's rival, Ogden Wernstrom. It was possible that her old age had caused her to forget this relationship, or she might not have really loved Wernstrom in the first place.
