Exterminatrix's big plan was to make an army of America robots.
Prodigy called on the school to fight back. He was then met by the six racist white people that also chose to attend Sotomayor University.
He was then saved by two fat lesbian robots. America then did the thing where she channeled so much of her power into a generator it exploded, killed all the America robots and Exterminatrix' plan to start an army at a progressive college failed.
America then decided she had to back to her home planet. But she did not die on the way.
