I hesitate to call this a Multiversal Role Play. This isn't quite a huge enough Crossover to include everything, but it includes a lot. To make a long story short, Shinra, from FFVII, Aneki Corporation, Weyland Yutani Corporation, Shinrai Ryu and Umbrella are all competing companies on this planet, which I'll call Third Earth. Oh, it's called Earth, but it's nothing like the Earth you and I know. There's an America, but Gotham, and New York might Co-Exist with Metropolis. . . Genosha could also be on the planet somewhere, the former prison for Mutants turned Mutant-Haven. Warp Drive has just been discovered, by Zefram Cochrane, various problems have erupted on the planet's surface, and there has been a massive Colony Ship meant to travel to the nearest solar system capable of sustaining life well enough to restart Humanity if it ends on this "Earth".
The Winchester Brothers fight Lucifer, the X-Men fight Magneto, Cloud and his friends do battle with the evil Shinra Corporation, and the last zombie/mutant out-break nearly destroyed Racoon City. . . Predators have almost casually hunted down their alien prey in city streets until it's Mutant and Hero population had enough of that, and the Out World sorcerer lord Shao Kahn got his butt whooped by Liu Kang. Rumors abound of Rogue Government agencies like Psi Core that kidnap young Telepaths and Telekinetics and force them to work for them under the disguise of patriotism or pragmatism, and the very organization was nearly utterly destroyed powerful Jedi and Sith in the recent past.
It has been suggested that the Third Earth is doomed. It's makers, some of them gods, some of them Q from the Continuim, from of them Ascended Ancients, and countless others, groan in frustration, disappointment or maybe boredom as they wait for things to either get better or try to make things better through their own hands. Senator Palpatine has recently been impeached and even kicked out of office of President by the work of Captain America and his friends Batman, Yoda and others who have discovered and exposed his plan to unleash a clone army of mutate-genetically (spelling, for the love of God, what's the spelling?) empowered, 100 percent loyal super soldiers and conquer the rest of the world, without even asking Congress!
What the Hell is going on? Some blame the Aneki Corporation, and it's rumored to be Dragon Crime Boss, others blame Doctor Doom. . . but everyone just thinks that the world has gone to crap because of too many bad people having far too much power. Some suggest things may have always been this way, and this may be true, but even the mortals and resident non-gods of the Earth have begun to lose their patience with the way things are. The expedition to other worlds put together by the UN will only serve to endanger Humanity wherever it goes, because of such the way things are.
Before I create a Character Sheet for others to write, you must first announce your character concept. You can choose almost anything, but you can't be an omnipotent or even a near omnipotent. You cannot be a very high level cosmic beings like the Phoenix. You might be something such as an original character as powerful as Palpatine, as strong as a weak/mediocre iteration of Super Man, or maybe something else I can't think of, but watch the power levels.
Third Earth (The Dimension, not just the planet) is meant to be a place where the characters come from, unless they are High Fantasy characters, where they come from their own settings
