Marvel Team-Up #124

Spider-Man and the X-Men's Beast make for a fun pairing in this December 1982 team-up, and the cover by Ed Hannigan and John Beatty wastes no time setting the stakes — both heroes are shown reeling under an assault from the armored Professor Power, whose massive mechanized fists send debris flying in every direction. The tagline promises Professor Power is "back — with a vengeance," and the image of Spidey dodging while Beast takes the fight head-on makes it easy to believe these two will have their hands full. As a bonus, the cover teases "a major new development in the life of everyone's favorite Aunt May," giving readers yet another reason to flip past that striking cover.
