Something Happened The worlds merged, The earths of two universes completely separate of one another became one familiar faces from both worlds met. AT first there was chaos of everyone trying to make sense of things the heroes and villains met Some Were friends some were foes some just Co existed. New tensions arise with the flow of time, what new heroes and what new stories might flow forth from the mingling of the two great universes.
the basic Idea.
Eternity and Kismet fall in love and become one in a form of cosmic matrimony for whatever reason the One above all the the presence allow this union which causes the merging of both the marvel and Dc universe together into effectively one universe.
All places within each universe exist as separate entities. Except for planets with the same names For example there is only one mars in this jointed universe though they are both joined this might bring the marvel and DC martians into conflict.
All organizations in both universes exist. A.I.M. Might come into conflict with S.T.A.R. labs for example. Or maybe the Nova Corpse might come into contact with the Green Lanterns, Maybe at times they work together.
This is not an amalgam universe, And i'm not trying to compete with that sort of thread. all the characters are separate from one another for the most part. There may be Amalgam-like characters like for example maybe one of you invents a Thanagarian who joins the NOVA corpse, He might be seen as an amalgam of Hawkman and nova but no actual amalgams,
Your mission should you choose to accept it is to make an interesting new character for this new universe ideally this character will be a marriage of themes and ideas from both universes.
Not good a writing a fan fic? Than maybe just throw an idea out there for someone to pick up. Or make a brief Scenario idea or even drop a picture here to inspire someone else.
Below below is a picture i threw togeather to get the ball rolling and as kind of an example idea on this new adventure into fan fiction.
