Tress MacNeille

Mom is the malevolent, foul-mouthed, cruel, and narcissistic owner of MomCorp, the thirty-first century's largest shipping and manufacturing company, with a monopoly on robots. In public, she maintains the image of a sweet, kindly old woman by speaking in stereotypically antiquated statements and wearing a mechanical fat suit. She occasionally launches insidious plans for world domination and corporate takeover.
