(This story takes place AFTER the events of mario and luigi dream team.)
When villains usually die in mario and luigi games, They end up in hell or someplace as worse.
Even though he had his ass royally kicked by Mario and Luigi, Antasma has returned from the grave for vengeance.
The one problem though is, He is no longer in Mario's universe, But in the My Little Ponyverse instead.
Regardless of his surroundings, Antasma still seeks out to conquer Equestria, I wonder how this will turn out?
