In the fictional Marvel Universe
, the hypothetical planet known as Counter-Earth
has thrice been created, each time as a near-duplicate of Earth.
The High Evolutionary Counter-Earth
The first Counter-Earth has appeared in Marvel Premiere
#1 (April 1972), Warlock
#1-3 (August-December 1972), #5-6 (April, June 1973), and Marvel Two-in-One
#61-63 (March-May 1980).
Counter-Earth received an entry in the Official Handbook of the Marvel Universe #17 (2005).
The first Counter-Earth was built by the High Evolutionary
with the help of at least some of the Infinity Gems
. This planet was inhabited by living humans. It was home to Reed Richards
' twisted counterpart, the Brute
, as well as to Necromancer, a counterpart to Doctor Strange
. It had very few superheroes and had Adam Warlock
as its champion for a length of time in the early 1970s, fighting mainly the Man-Beast
and his allies. It was eventually moved away from the solar system by the Beyonders
and destroyed during Infinity Gauntlet
This version of Counter-Earth (albeit with some differences, such as the existence of animalistic counterparts of various Spider-Man-related characters) appears in the cartoon Spider-Man Unlimited.
The Goddess' Counter-Earth
The second Counter-Earth, dubbed Paradise Omega, was built by the Goddess
, using the Cosmic Egg, a collection of 30 Cosmic Cubes
. Unlike the other two Counter-Earths, it had no animal life at all and served as the base for the Goddess' chosen heroes. Its existence was only brief; it was destroyed at the end of Infinity Crusade
#6 by Thanos
telling the Cosmic Egg to self-destruct.
The Franklin Richards Counter-Earth
The third and current Counter-Earth was built by Franklin Richards
in the transition from Onslaught
to Heroes Reborn
. It briefly hosted the reborn Fantastic Four
, and was, for a short time, rechristened Planet Doom when Doctor Doom
managed to conquer it. It originally inhabited an alternate "pocket universe" which was created at the same time, but was moved into the "prime" Marvel reality (Earth-616
) when the pocket universe's instability caused major planetary upheavals; it was at this point, when this duplicate Earth was placed roughly opposite the true Earth in the same orbit, that it was christened as the new Counter-Earth. More recently the Thunderbolts spent some time there, leaving Jolt
behind when they returned. It is currently home to Jolt and her current team, the Young Allies
The Exiles, a team of superheroes from alternate realities, fooled the reality-warping Proteus into going to Counter-Earth instead of the "main" Earth and followed him there. Proteus raised the undersea civilization of Atlantis to the surface, killing all of its inhabitants. The cosmic entities "O" and "Kay" (Order and Kaos) believed that Proteus' presence was the final straw requiring that Counter-Earth needed to be destroyed, and commissioned Proteus to do the job. Proteus gleefully agreed but was stopped by the Young Allies and the Exiles.
A variant version of this Earth is seen on Onslaught Reborn mini-series with counterparts of Fantastic Four, Captain America and others still inhabiting it. This mini-series takes place not long after the Civil War event.
