What if, true believers, what if? What if instead of the lackluster Alien sequels that we were saddled with (beginning with Alien3) we got a more Starship Troopers-style invasion pic? Just imagine a full-on war, here on Earth: Colonial Marines in grand, pitched, shoot-em-up battles with hordes of xenomophs. It would’ve been quite a spectacle, and would’ve looked sickeningly gorgeous in CG. Those big piles of zombies in World War Z? Imagine thousands of leaping, skittering aliens; tails thrashing, secondary mandibles biting, and now and then one gets blown to bits and soldiers get showered with acid. The utter chaos of it all, the thrill, the terror, the underlying message about the futility of war…it could’ve been great. Would humanity survive? Or would the alien menace simply overwhelm the stalwart armies of mankind? A pity that we’ll never get to see how such a dramatic and potentially tragic conclusion would’ve played out.
Unless we already have.
What if the post-alien fate of humanity has already been told via two different sci-fi television series and a classic film? I will now present to you a tale which I believe to be a completely plausible multi-level saga. Follow along. Be patient, because this shit gets good. Good and deep, just like shit gets sometimes. Yeah. Okay. I didn’t need to actually type that. Okay. Good. Moving on.
Our story begins on Earth. Either Ellen Ripley or another one of the Weyland-Yutani Corporation drones manages to deliver a few viable xenomorphs to our fair planet. And as they do, the damned things get loose. They run amok and cause a great deal of trouble for the humans that are still here on this rock.
“Still here?” Did you read that correctly? Yes. Yes, you did. This brings us to our first Easter egg. You may have heard the fan theory about how the Weyland-Yutani corporation (the Alien franchise) exists in the same world as the Tyrell Corporation (Blade Runner.) Most of it is simply fanboy conjecture, but then Ridley Scott chimes in and basically confirms in an interview that the heads of those two mega-companies did indeed know one another. Interesting.
Okay, sorry. Focus. In Blade Runner, most people with the means to do so have gone “off world.” Those that remain on our spent husk of a planet deal with smog, pollution, constant drizzle and greyscale everything. Now, notice we never see much of Earth in any of the Alien movies? Ripley lives in what might be tenement housing, or even a block of company-made dormitories. Maybe the world outside is the same bleak cityscape whose streets guys like Deckard patrol. Of course, we humans aren’t the only sentient beings that inhabit future-Earth. There are the skin-jobs. Replicants made by the Tyrell Corporation, and equally-lifelike synthetics produced by Weyland-Yutani.
Still with me? Okay.
So, the aliens go nuts and are on the verge of wiping out what’s left of humanity, or at least the shreds still clinging to our turd of a planet. So the rest of the humans take off. Get out of Dodge. Split. And who do they leave behind?
The robots. Replicants. Artificial persons.
Those thinking machines of various mechanical and genetically engineered construction stave off the aliens until the rest of us can get off-world. Just maybe everyone is getting off-world because of the alien invasion. Whatever the case, the plan is to let the aliens run out of human hosts and die, so that mankind can return and resume our civilization. (Think WALL-E only much darker.) Only it doesn’t work out that way. The bio-mechanical xenomorphs, as we’ve seen in the sequels, can adapt to whatever host organisms are present in any given environment. Perhaps even bio-engineered skin-jobs. Eventually, the aliens are just too numerous. The replicants are faced with one final option: take off and nuke the site from orbit. And by “site” I mean THE WHOLE DAMNED PLANET.
I’d imagine it would come down to some sort of group decision, maybe a cadre of inner-circle synthetics who finally made the call. And what if one of them was modeled after the son of corporation founder and head genius Eldon Tyrell? Maybe he has a similar name. And maybe over the centuries that followed mankind’s exodus, the spelling of the last name changed (much like Shawn, Sean, or Shaun. Emory and Emery. The various Mac and Mc spellings of Scots and Irish surnames.)
Yes, Eldon Tyrell’s legacy is Galen Tyrol. One of The Five. The Five sentient mechanical beings who at one point were more human than human, even capable of sexual reproduction. The Five that nuked our planet in order to finally destroy the alien menace.
And what of humanity? Of course, most ended up living on Kobol or Caprica. But another group, the REAL “lost tribe” found their way to another system (or systems.) There, as on Earth, the monolithic corporations seized power. There, like on Earth, the rich were able to live life flush with the latest technology. Others, not so much.
In fact, some folks keep using the old tech of Earth That Was. For example, this anti-aircraft gun…made by the Weyland-Yutani Corporation.

See that logo? Top center? Keep in mind, this is Mal Reynolds’ gun from the battle of Serenity Valley.
All this has happened before, and all this will happen again.
ADDITIONAL EVIDENCE:
There’s a very Asian feel to Deckard’s Blade Runner city. Much like the preponderance of Chinese influence in the world of Firefly. And when Anders becomes the “hybrid” in BSG, the walls show cascading symbols that seem to be either Chinese or Japanese in nature. And maybe Kara Thrace isn’t painting the Eye of Jupiter in this piece…
…but rather this…
Kara Thrace. No power in the ‘Verse can stop her. And finally…FINALLY…while there are several toy spaceships that make an appearance during a shadow-puppet theater show in the Firefly episode “Heart of Gold” (like, is that the Enterprise at the top?) the circled ship could be a Colonial Viper, yes?
Okay, maybe a stretch. However, in the original Battlestar Galactica re-imagined mini-series, the following ship does a fly-by outside the doctor’s window there in Caprica City. Huh. Wouldja look at that?
IN CONCLUSION:
There will be folks that pick this apart and do some sort of timeline reckoning and poke numerous holes in my theory. Fine. It’s just silly fan stuff, and that’s one of the wonderful things about the sci-fi community; the endless debates and comparisons. Bottom line: it’s all good. Literally. There are some wonderful stories and grand mythology out there. Dig in and enjoy ‘em all. And expand upon them! This sort of conversation could go on forever! Was the Predator that came to earth in the near-future Los Angeles here to hunt Aliens? Were they already present? Perhaps they actually began life here on Earth! Bio-engineered by Weyland-Yutani and shipped off-world to incubate on another planet, another system, far enough away to pose no danger to mankind.
Was the rainy, grey nature of our planet in Blade Runner the result of some last-ditch effort to terraform our own homeworld after it was ruined by pollution and greenhouse emissions? Is that why it looks so much like Acheron/LV426? Constant drizzle and gloom? In an alternate timeline, did a synthetic (sorry, artificial person) begin Star Fleet, because Commander Data? Is Earth an offshoot (lost colony) from some race in Star Wars? And did THESE GUYS…
Inspire THIS GUY?!?!
This has all happened before, this will all happen again. A long time ago, in a galaxy far, far away…
My head hurts. G’night, all.
