Merging (universes) – The ability to merge two universes.
This might be the ultimate superpower since the character doing this is not doing (371) Reality Warping with one reality but two realities! Even the Infinity Gauntlet does not work outside the unmerged Marvel universe in the Avengers/JLA crossover event.
Actually, Infinity Gauntlets don’t even work in other Marvel universes. Reality warping in one universe does not mean you can change the reality of the multiverse much less the omniverse. The three Reed Richards, of the Interdimensional Council of Reeds, pictured below can only warp the reality of their universe within the Marvel multiverse with their infinity gauntlets (Fantastic Four #571).
Cross-over universes would be an example of cross dimensional manipulation not merging universes. In a cross-over universe, characters from two universes interact as part of a larger shared universe but the characters themselves have not merged. This was done in Superman vs. the Amazing Spider-Man, Superman and Spider-Man, DC Special Series #27 (Batman vs. Hulk), and The Uncanny X-Men and The New Teen Titans #1.
The first major merging of universes happened in Amalgam Comics. Characters in the DC and Marvel universes have been merged into a single character.
