YMMV / Zombie Heartbreaker

• Complete Monster: MOM is the A.I. leader of the Space Pirates, a gang of dangerous criminals responsible for the destruction of numerous planets. MOM adopts Riley and Kraig and transforms them into ruthless pirates responsible for untold death and destruction. MOM is the true mastermind behind the creation of the blue gas plague, which she used as an experiment on the Mario World, resulting in a skeleton apocalypse that nearly wiped it out. When Riley tried to kill MOM, the latter continued leading the space pirates from the shadows and planned to eliminate both her adopted children for their betrayal. After Riley is defeated, MOM shows up and declares both of her adopted children to be failures and sets the space station on a collision course with the Mario World to wipe it all out so MOM can continue her experiments.
