Earth One

Earth One is a universe parallel to a plethora of others, such as Earth Two. The name was coined by Martin Stein. To Earth Two citizens Earth One is referred to as Earth Two. Also, to an unidentified Earth's citizens, it is known as Terra Prime.

Earth One is particularly important in that it is central in the multiverse, being the middle point in which you can travel to any other alternate Earth.

History
