The Lord of Latveria and Atlantis’ Avenging Son forge the Marvel Universe’s most volatile alliance! But when the Sub-Mariner regrets his decision, he finds it’s not that easy to walk away from a pact with Doom. Can anything get him out of this torturous team-up?

When Captain America sides with Doom, you know you’re in trouble. But both Doom and the Skull plan to enslave the Earth — and the only ones standing in their way are Magneto and the Champions! Introducing the Shroud and featuring the villainy of the Hate-Monger! Collecting GIANT-SIZE SUPER-VILLAIN TEAM-UP #1-2, SUPER-VILLAIN TEAM-UP #1-14 and #16-17, AVENGERS (1963) #154-156, and CHAMPIONS #16.
