I had something similar in mind with the Avengers film franchise of an alternate reality beginning in Avengers Assemble that change the course of events upto Age of Ultron and post Ultron with major changes, due to dimension breaches. But my character is a non-canon unfortunately to allow the manipulation of the timeline changes in the first place. And also I have cross realms with Valhalla, the nine worlds, Hell and all of its wonderful creatures as enemies so that people could play any race they wanted be it angel, vampire, demon, Asgardian, Frost Giant.

Other than that I'm already part of a Marvel alternate universe rp as canons only. So I don't really wish to do another canon from the same universe. That's why I didn't end up making mine as there was one going already. :)
