Merging (universes) – The ability to merge two universes.
This might be the ultimate superpower since the character doing this is not warping one reality but two realities.
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.
