As one of the richest people on Earth, Mom maintains her public image as a sweet, matronly figure through the use of things such as a fat-suit, a heart-shaped hairdo and putting on a facade which casts her as the friendly mother of all robots hiding her True Persona.

Mom’s personality is best described as: Misanthropic, two-faced, pure greedy, sinister, cunning, narcissistic, foul-mouthed, intensely arrogant, harsh-tempered, megalomaniac, ruthless, scheming, cold-hearted, argumentative, cruel, witty, wrathful, callous, resourceful, neglectful, uncaring, sophisticated, evil, malevolent, resentful and above all a true sociopath.

All robots produced by MomCorp have been equipped with a device that allows Mom to force them to do her bidding, although she appears to have used this only once on Mother's Day (holiday) in 3003. She receives yearly Mother's Day gifts and cards from the robots, which she turns into hocus-pocus cures for cancer and orphanage-grade toilet paper respectively.
