Found the Justice League (with an alternate roster)

You decide to join the ranks of heroes, but not as some random wannabe. You will be among the bests of the bests. You will retcon the universe in order to join the Justice League from the beginning.

First, you need to turn yourself into a hero. You cannot just go around and solve every situations with god-like powers, you need to blend in. Sure, you won't renounce your omnipotence, you simply won't use it as long as it isn't needed.

You will be known as Meteor. You have superstrength, superstamina, flying hability, telekinesis, telepathy, control over gravity and you can shoot power blasts seemingly made of light. Actually, the limitations of your power will be unclear, it's not like DC is used to it. You don't hide that you come from another dimension, but stay mysterious about it. You're tall and muscular, with golden hair and yellow eyes. Your voice and face are a huge adventage with women, even though nobody can remember what you looks or sound like when they're not directly exposed to you, and mikes and cameras always malfunction when trying to record you.

Now, about the team... It won't be the classical one. To begin with, you want more women. Sexy women, obviously.

You decide that, in this version of the DC universe, Power Girl will replace Superman entirely, and Atlantis will be ruled by Mera. They are both founding members of the Justice League, together with Wonder Woman, Zatanna Zatara, Black Canary and, obviously, yourself. You don't want the team to be to suspiciously female, and also make Batman, Flash, Martian Manhunter and the Green Lantern John Stewart part of it. But you don't really plan on sharing those super booties with them.

You add a few more details to the world, adapting other characters to your ideas. Once satisfied, you put your universe in motion...
