Earth-163

Earth-163 (or the Age of Primitives) is a post-apocalyptic alternate reality where Primitives became the dominate species of the planet, leaving humanity and other related species hunted, enslaved, scattered, or nearly extinct.

Overview
In this universe, Apelink, a primitive terrorist, succeeded in overthrowing humanity and making primitives the dominate species of Earth. Many human lives were taken as a result of the primitives' uprising, and any attempt by the humans to fight back was futile. Apelink's first targets were Allen, Miguel, and their primitive followers who wished to protect humanity and oppose Apelink's rise to power. Seeing them as traitors, he gave them a choice to either serve him or be executed. He began his campaign of world domination by destroying the heroes and villains who opposed him and primitive kind, resulting in the destruction of most of the members of the Avengers, the X-Men, and the Fantastic Four.

He then began a campaign to remold the Earth's ecosystems in his own image, primarily for primitives to prosper in. Most of the United States and the lower parts of Canada in North America became a large cold desert, probably larger and more colder than the Sahara desert. Mexico was more hotter and grew into a tropical paradise. South America was more tropical as well, restoring all the tropical rainforests that were cut down by humans. Africa became hotter and more lusher with rainforests and grasslands. Europe became colder and was covered in snow and ice. Asia was inbetween, with upper parts like Russia growing more into a frozen tundra and lower parts of the continent growing hotter and covered with rainforests. Australia became mostly a desert, with rainforests found more in New Guinea, even though Australia has rainforests near the ocean.

All of human civilization was abandoned, with most cities left to decay and quicly being covered in green due to the release of carbon dioxide, creating natural habitats for some animals. Facilities like power plants exploded without mankind's maitanence, creating several death zones.

The surviving humans who weren;t captured or killed were found in either compounds or in abandoned towns, who planned to create an army to overthrow primitivekind. Some humans became nomads, who were more peaceful and wished to find a paradise where they could be safe from any other humans or primitives who wanted to kill them.

Mutants were just as threatened as humans. Most mutants found snactuary in an underground city called Utopia founded by Magneto, who survived the primitive uprising while his longtime friend and enemy, Charles Xavier, didn't. Without Xavier and the X-Men for mutants to look up to, Magneto took up his longtime cause and started to form an army to oppose primitivekind and retake the world. Those who didn't believe in his cause, like his ex-fiance Rogue, decided to leave the city and live a nomadic life.
