“I, Lucifer...”

The X-Men collide with a mysterious silver-suited villain outside a bank on Werner Roth and Dick Ayers's kinetic cover for this 1966 installment, with Cyclops, Angel, Beast, Iceman, and Marvel Girl all visible in the thick of the action. The tagline teases the story title "I, Lucifer!" while a lower panel promises the untold tale of how Professor X lost the use of his legs — Roy Thomas and Jay Gavin delivering two compelling threads in one issue. For fans of the original X-Men lineup, this is a satisfying slice of mid-1960s Marvel at its most ambitious.
