Collects Uncanny X-Men (1963) #43-53, Avengers (1963) #53, Ka-Zar (1970) #2-3, Marvel Tales #30. Get ready for a crash course in X-MEN, students! Lesson #1: It ain’t easy being a mutant. No sooner has their mentor, Professor X, died than Magneto and the Brotherhood of Evil Mutants show up! Only a study in teamwork with the Avengers can help our grieving heroes make the grade. Lesson #2: Think twice before inviting family over. A friendly house call from the Juggernaut or Polaris, daughter of Magneto, isn’t an appealing off-campus adventure! Lesson #3: Battling enemies including Mesmero, Blastaar, Red Raven, Warlock and Computo may cause cramps. Be sure to stretch before jumping into this pool! And for extra credit, pull an all-nighter with the origins of Iceman and Beast, and a rare Angel solo story!
