Earth's Mightiest Heroes fight one of the greatest battles in super hero history in the pages of this Marvel Masterworks spectacular. It's hero against hero in the summer hit of 1973-the Avengers/Defenders War. Cap vs. Namor. Thor vs. Hulk. It's the original crossover clash and there's never been another one like it. Plus: Mantis makes her debut; the Lion God brings the Avengers to their knees; Vision and the Scarlet Witch's relationship blossoms, but not without the intolerant objections of others. Collecting: Avengers 112-119, Defenders 8-11, FOOM 6-7
