O.O Sooooo many great ideas! Maybe it'd be best if we all took a vote and then went from there, since some want a more simpler plot while others want one that is a bit more fleshed out..? Yay or nay?

If we vote, I think it is more than one topic to vote over.
Who?
()Canon Only(including cannon alternate)
()Amalgam
()Originals Only
()All
When?
{}Past
{}Present
{}Future
{}Alternate timeline
Where?
[]Two worlds permanently linked(an open portal in a major city for free flowing traffic 24/7, for example.)
[]Two worlds separated (rare occurrences and limited travel)
[]One world amalgamated (supergladiator flying over Metrocago while darkclaw swings through gothyork)
[]One world apart (Batman trades blows with doctor doom in the blue forest of Pandora)
Why?
<>Contest(good versus evil, one universe versus another)
<>Conflict(all versus one opponent)
<>Conquer(some seeking to use this opportunity to their advantage)
<>Confusion(WTF?!?)
