Avengers #101

« Five Dooms to Save Tomorrow »: The Avengers encounter Leonard Tippit, an ordinary man glowing with power, who vanishes upon his defeat. In a vision they learn that the Watcher warned Tippit that unless he killed five innocent humans, all of Earth’s possible futures would end in atomic war. Thor, Captain America and Hawkeye, the Vision, Quicksilver and the Scarlet Witch each fail to save one of his targets, but Tippit himself is captured and Iron Man drains his power. The Watcher reveals that Tippit is the actual cause of the coming nuclear holocaust; with his victims restored, Tippit lets the Watcher remove him from normal time and space.
