Breakworld is a planet in constant war where some prophets predicted it would be destroyed by a mutant of planet Earth, who turned out to be Colossus. It was ruled by Powerlord Kruun, while a secret movement led by Aghanne was trying to establish a healing center. The S.W.O.R.D. and the X-Men landed here to find out how Rasputin could have been a threat, nullify that threat and take out a huge missile pointed at the Earth. After they managed to get on a spaceship, they all left the planet to reach the moon-based weapon.
