DC vs. Marvel
DC vs. Marvel Comics (issues #2–3 titled Marvel Comics vs. DC) was a comic book limited series crossover published by DC Comics (Detective Comics) and Marvel Comics from April to May 1996. The series was written by Ron Marz and Peter David, with art by Dan Jurgens and Claudio Castellini.
Two godly brothers who personify the DC and Marvel Universes become aware of the other's existence, and challenge one another to a series of duels involving each universe's respective superheroes. The losing universe would cease to exist. The story had an "out of universe" component in that the outcomes for five of the eleven primary battles were determined by a fan vote.
Numerous smaller, story-driven skirmishes occur throughout the series, not counted with the primary duels meant to determine the outcome between the brothers.
The first six primary battles were:
Aquaman (DC) vs. Namor (Marvel). Aquaman won by crushing Namor with a whale.
Elektra (Marvel) vs. Catwoman (DC). Elektra won by making Catwoman fall off a building.
