it might be interesting, there was this comic book series
DC vs. Marvel Comics (issues #2-3 titled Marvel vs. DC Comics) is a comic book limited series crossover published by DC Comics and Marvel Comics from April to May 1996. The series is written by Ron Marz and Peter David, with art by Dan Jurgens and Claudio Castellini.
Two brothers who personify the DC and Marvel Universes become aware of the other's existence, and challenge each other to a series of duels involving each universe's respective superheroes. The losing universe will cease to exist. The story has an "out of universe" component in that although there are eleven primary battles, (primary six with winners in bold type: Aquaman
vs. Namor; Elektra
vs. Catwoman; Flash
vs. Quicksilver; Robin
vs. Jubilee; Silver Surfer
vs. Green Lantern; and Thor
vs. Captain Marvel) five of the outcomes are determined by fan votes (winners in bold type: Batman
vs. Captain America; Spider-Man
vs. Superboy; Storm
vs. Wonder Woman; Wolverine
vs. Lobo; and Superman
Marvel Comics receives more votes than DC Comics, although the storyline does not show one side as being victorious. As part of a last-ditch effort to save their worlds, the Spectre and the Living Tribunal were able to briefly force the "brothers" to resolve the situation by temporarily creating a new universe, called the Amalgam Universe, which is occupied by merged versions of many of the heroes (such as Dark Claw, a merging of the characters Batman and Wolverine). An inter-dimensional character called Access eventually manages to restore the universes to their normal state with the aid of Batman and Captain America, the presence of the two heroes- essentially serving as the brothers in miniature, each being unique among their peers- forcing the brothers to recognise how petty their disagreement truly was.
