Let's probe the Multi-Verse!

Anyway, as you've probably heard, Prometheus is a pseudo-prequel to Alien and depending on how you look at it, is Alien 5, Alien 0 or Alien 10. Below I have summed up the complex web of relationships between the canonical film entries in what we shall call the Alie-predmetheus-iverse. Behold:

It's a slutty, slutty multi-verse.

Fred and George come to the terrifying
realization that they've touched each
 other's continuities...and enjoyed it.

Somehow, when we weren't looking, the universe in which the Alien movies are set ballooned into a multi-franchise mega-verse which may or may not include Doctor Who. Yeah, Doctor Who, but we'll get to that. At first it may appear that these connections make for a rich narrative tapestry but it's easy to forget that when you moosh your fictional world up with someone else's fictional world you're also mooshing with every other continuity your partner has ever mooshed with. It might seem like fun at first, but then you wake up one day and find that it hurts to pee.

"Gee, I was kind of hoping you'd explain
your plan thus exposing some kind of weekness
I could exploit...possibly with my batarang..."

-Batman, somewhat in over his head

Which brings us to Doctor Who. Yeah. So the Alien and Predator Universes were officially linked up with AVP, but they'd already versed (?) each other years ago in the comics. The crossover movies simply cemented the connection. You know who else met a Predator? Batman. Yeah, in the cleverly titled Batman Vs. Predator. Depending on where you draw the lines of canonicity (do comics count, or are they what-if's?) this links the entire DC universe with the Alie-pred-metheus-iverse. Still with me?

Since DC's Legion of Superheroes recently hooked up with the crew of the original Starship Enterprise and Captain Kirk's successor Captain Picard engaged in some hot transdimensional shenanigans with the Eleventh Doctor, the argument can be made that little stands in the way of Ellen Riply throwing down with some Daleks in Alien 5: Cross-promotion.

Of course this also opens the possibility of a Xenomorph tearing it's way out of
