What If (Vol. 1 1977-1984) #29

Plot

It's a world like the one in Avengers Annual #2 where the Scarlet Centurion tricks the original Avengers into taking out the rest of Earth's heroes, but the future Avengers of another reality didn't arrive to foil the Centurion's plan. The Hulk eventually turns on them, but is defeated by the Avengers and added to the Centurion's collection. The remaining Avengers voluntarily retire and the Scarlet Centurion seizes the opportunity to attempt to take over the world. Iron Man, Thor, Giant-Man, and the Wasp reunite to defeat him, but decide to stay retired afterwards.
