The heroes triumphantly defeat Per Degaton on Earth-2 in 1942 (reverting
him to a lowly lab assistant to Prof. Zee in 1947, remembering the
events he caused as only another dream), as well as the Crime Syndicate
(returning them to their limbo prison in the Earth-3 universe),
returning things to normal on both Earth-2 in 1982 and Earth-Prime circa
1962 (with all forgetting this adventure ever happened).

INFINITY GAUNTLET #1 (Jul 1991)
Marvel Comics
On May 21, 1991, the Mad Titan upended existence with a single click of his fingers, killing 50% of life, and leaving the Super Heroes of the Marvel universe with the greatest fight in history ahead of them. Led by the resurrected Adam Warlock and aided by primal cosmic forces, Earth's protectors entered cosmic warfare in a six-issue event written by Jim Starlin and featuring the art of George Perez and Ron Lim. And 28 years later, the reverberations of this one action are still echoing across the world!
