After receiving a direct blow to his head from Buttercup, Mojo Jojo was ROCKED beyond full recovery. That sent him into early retirement, and now he wreaks havoc on the nurses at the Townsvillain Retirement Home.
Professor Utonium spends most of his time at home conducting experiments and testing out his countless inventions. The girls still visit him every day and he STILL tries to make them eat their broccoli.
Buttercup still lives with both her sisters defending the town from various villains and monsters. She visits Mojo Jojo in the retirement home sometimes because she feels bad for sending him into early retirement.
