Uncanny X-Men #183

Peter reveals to Kitty his romantic affair with Zsaji, the beautiful alien healer he met on Battleworld (see Marvel Super Heroes Secret Wars [1984] #5), thus breaking the young girl's heart. Determined to set the boy straight, Wolverine and Nightcrawler take Peter out for a night on the town. Unfortunately they end up at the same bar as the notorious Cain Marko. What follows is the most earthshaking battle between Colossus and the unstoppable Juggernaut ever seen. Plus, the introduction of a deadly new X-Men villain.
