Earth 1

Earth 1 (1), also referred to as Universe 1, is a universe parallel to a plethora of others, such as Earth 2. The name was coined by Professor Grayson. To the citizens of Earth 2, Earth 1 is referred to as Earth 2. Earth 1 is the primary setting for every major event.

Earth 1 is particularly important in that it is a central junction in the multiverse, being the middle intersection from which one can travel to any other alternate Earth.

History
After learning of the existence of parallel worlds, Professor Grayson coined the world's name, "Earth 1", as he is a fan of comic books, to describe Team Zero's relative position in regards to all of the other worlds. Beginning in the early 21st century, it has become home to numerous groups of extraordinary protectors, such as Team Stryker and the Legends, recruited by time traveler Kate Fletcher and vigilante Arsenal and their allies who emerged after the explosion of Kane's particle accelerator that gave rise and prominence to super powered meta-humans and Austin Chambers' release of nanites into West City, the android Zero and his team of allies who clean up South City from scientifically enhanced villains, and Bianco Academy which is home to the next generation of superheroes. Even in other times, similar such heroes operate, such as the secret mid-20th century alliance the Council of Justice, which had continued until sometime before the Xeno Offensive in 2024.
