The X-Men finally witnessed the apparent end of the Brotherhood of Evil Mutants following an encounter with the alien Stranger, ending with the Stranger taking Magneto and the Toad to his planet for study, and transforming Mastermind into dense matter..However, the robots revolted against their master, capturing Trask and the Professor and taking them to their new robotic leader, Master Mold.Factor Three struck again when the Professor attempted to cure his step-brother of being the Juggernaut.The resulting experiment of both science and sorcery ended with the Juggernaut's revival and the Professor on the brink of death.The X-Men gained another ally in Ka-Zar when an investigation of his existence at the South Pole led to the discovery of the Savage Land.The X-Men aided Ka-Zar and his saber-toothed cat, Zabu, in defeating the Swamp Men.The group found the X-Men "guilty" of betraying mankind and sentenced them to death.
Arriving in Europe, they were captured by Factor Three, whose membership included the Vanisher, Blob, Unus, Mastermind as well as two new villains: the Changeling and Mutant Master.
