Among the great cartoon villains of the ’90s, none spoke — or schemed — quite like Mojo Jojo from The Powerpuff Girls (1998). Once the lab assistant of Professor Utonium, an accident gave him super-intelligence — and an ego to match. With his oversized brain, green face, and magnificent purple cape, Mojo Jojo became the ultimate overexplainer, plotting endlessly (and talking about it even more).
Voiced with manic brilliance by Roger L. Jackson, Mojo was equal parts mad scientist and comic genius. His endless tirades, spiraling logic, and constant defeats made him both hilarious and oddly sympathetic — a villain too smart for his own good.
Whether building doomsday devices or just trying to outwit three superpowered kindergarteners, Mojo Jojo remains an icon of animated absurdity — a reminder that evil can be smart, silly, and spectacularly self-defeating.
