In this penultimate chapter of the "World's End" arc, the X-Men find themselves in the Savage Land, facing a formidable new threat: the reptilian Hauk'ka, who aim to conquer Earth using the X-Men's own powers. To combat this menace, the X-Men form an uneasy alliance with Ka-Zar and the Savage Land Mutates. Amidst the chaos, Psylocke employs her unpredictable psychokinetic katana to restore Bishop and Nightcrawler's mutant abilities. As the battle intensifies, internal conflicts arise, particularly with Rachel Grey, who begins to fall under the Hauk'ka's influence, jeopardizing the team's unity and the mission's success.
