A reprint of X-MEN #5 (1964) in this issue, a 24-page Kirby/Reinman story, with the second round of the ongoing battle with Magneto's Evil Mutants. As we begin, they're recovering from their last encounter, which has left Professor X without his powers. A few odd scenes follow, with a visit from Jean's parents and Cyclops accidentally left in the Danger Room to provide an action sequence.
Shortly thereafter, Magneto has the Toad pose as a competitor in a track meet showing mutant powers in order to lure in the X-Men, hoping to reveal their headquarters.
They unmask him in time, leading to a battle on the subway, and then the Angel is taken prisoner aboard Magneto's Asteroid M headquarters. The X-Men follow, and are able to prevail and escape thanks to Quicksilver and the Scarlet Witch being reluctant to follow Magneto's commands to the point of murdering the X-Men. I wonder at what point it was decided they would join the Avengers? Anyway, the X-Men return home and find out that, among other things, Professor X is a jerk.
As I'm sure I've mentioned before, I'm not a huge fan of Reinman's inks compared to some of the other inkers of the era, but he does preserve most of the interesting things in Kirby's art.
