Your gateway to endless inspiration
Alright this is so great. Honestly, I’m not sure why I had never considered that possibility that Raven Beak already had samples of Metroid biological material and they were simply destroyed during the outbreak. That makes perfect sense. It certainly plugs the hole of “why did the Mawkin return to ZDR without any Metroid samples?” This certainly fits that and makes it much more understandable. Plus it helps the X seems far more intelligent but seeking out and destroying mere genetic material, not even a reproduced Metroid, because they knew the danger it could pose if the Metroids were reproduced. Plus the idea that they had been keeping track of their numbers and the Metroids were inexplicably reproducing makes the Chozo seem more intelligent and adds a layer of Dread to the situation. Having things go wrong is all the more terrifying when you did make failsafes, but those failsafes didn’t stop the problem.
Overall, good stuff here.
I like to think the Thoha Chozo had a very Jurassic Park moment when dealing with the Metroids' rebellion on SR388. Think of it this way; You need a bioweapon that can destroy the X, so you take DNA from a wide variety of other organisms on SR388, and splice them into a perfect chimera. You'll need a lot of these, so you program this creature to undergo mitosis when exposed to beta-rays. That way, your machines only need to create one 'Metroid' from scratch, and then it can be used to spawn the rest.
But here's the thing; After the Metroids devour the X, they start to transform and mutate. Turns out, using the DNA of other creatures has caused additional traits, originally deactivated in the creation process, to emerge thanks to the unique conditions of SR388. This results in them mutating into the Alpha, Gamma, Zeta, and finally Omega stages.
This isn't hopeless though, far from it; Unlike the X, the Metroids aren't natural creatures and can't reproduce on their own. They need beta-rays, and/or the device that spawned the original Metroid. Since SR388 doesn't have any natural source of beta-rays, all you have to do is turn off the devices that emit them, and the original Metroid creator, and there! The Metroid population will always be the same.
From there you just need to destroy them one by one, and luckily the Mawkin have showed up to help; Normally your relationship with them is suspicious to the point of programming Metroids to be hostile towards Mawkin, for fear they would exploit the 'Ultimate Warrior' as a weapon. But instead, the Mawkin seem to have some genuine heart and are helping you handle the threat, and you need all the help you can get.
You accept them and conveniently don't bring up the anti-Mawkin programming, because as far as they can tell this aggression is indistinguishable from how metamorphosis has made the Metroids hostile towards you, their creators. Progress is slow yet tangible, and you keep track of how many Metroids the Mawkin have killed, and compare that number to the Metroids you created and cloned. You reach that number, and can now rest easy.
...Then you hear a report of a Metroid attack, and something definitely isn't right. How is there another Metroid, you killed all of them, you kept track of their numbers and everything! Is there something wrong with the original tally? It's not as if the Mawkin could've been mistaken on whether they killed a Metroid or not... But just in case, you engineer devices that absorb Metroid DNA whenever they die, just to have physical evidence; Otherwise, Metroids disintegrate completely upon death, so there's no physical 'proof' to reassure yourselves with.
The Mawkin keep finding more and more Metroids and now you're baffled. You check the original Metroid creation machine and it hasn't been used since the first and only time; But you take it apart, in case... Someone's been making Metroids behind your back, somehow? But the numbers keep continuing. You take apart all your beta-ray emitters, but there are still more Metroids. Is Raven Beak creating Metroids behind your back? But why let his soldiers die to them?
You scan SR388 for any beta radiation, and then you find a big one deep underground. You send Mawkin soldiers to investigate it, and only one makes it back alive. You thought the Omega was the final stage in the Metroid lifecycle; But somehow, another one emerged. Of the many species whose DNA was used to create the Metroids, one of them relied upon a lone queen to produce offspring. Another was capable of emitting its own beta-rays.
You know how some real-life animals, if there isn't a member of the opposite sex, will adapt by having a few transform into that sex so reproduction can occur? Something similar happened with the Metroids. Without a source of beta-rays, one of their own mutated into a Queen capable of emitting beta-rays within her own body, which she uses to produce eggs that hatch into newborn Metroids. And this Metroid Queen has been filling in the ranks that the Mawkin have attempted to deplete. And now the original number of Metroids that the Thoha cloned has been exceeded.
At this point, the Metroids are too numerous and powerful to defeat. But they haven't ventured to the surface of SR388, being isolated to its caverns; So you opt to seal away the Metroids by filling passageways with poisonous water. In case anyone is foolish enough to try releasing all of them at once, you program these Chozo Seal mechanisms to require a certain amount of Metroid DNA to divert the poison; This way, the Metroid population needs to be lowered to access more. And this acts as a way to gauge if those who come back to destroy the Metroids for good are competent enough to get the job done, and don't just end up releasing all of the creatures onto SR388 in their failed attempt.
That last bit is important, because you and the Mawkin plan to retreat back to ZDR, and gather more weapons, troops, and resources to return to SR388 and properly destroy the Metroids this time; Because now they know about the Queen. Theoretically, the Chozo could just destroy the planet... But they want to minimize destruction, so confronting the Metroids head-on will spare the rest of the ecosystem, as was the intention.
Alas, seeing the continued power and adaptability of the Metroids on display has intrigued Raven Beak; He finds their potential impressive, and has changed his mind. It's been deduced that the source DNA of the Metroids reacted to the environmental stimuli of SR388, the world that evolved and nurtured those organisms. But without the cradle of SR388, the source DNA will not thrive, and will not activate the other suppressed traits; Larval Metroids can't access the rest of their life cycle in any other environment.
ZDR has powerful biomechanical supercomputers called Central Units, which have telepathic abilities that enable them to control machines; Given larval Metroids were designed to respond to Chozo commands, and the use of Chozo DNA in the organic aspect of the Central Units, these AI can be used to control larval Metroids. As long as Metroids of more developed stages aren't present to rally them -the authority of Alphas and beyond will naturally override any Central Unit's- the larval forms will remain obedient.
And while the larval Metroid is just the tip of an iceberg the Thoha had never intended, what they did intend was already incredibly dangerous and powerful in and of itself, being designed to combat the deadly X and the many forms they could assimilate. So Raven Beak wouldn't need his Metroid army to metamorphose beyond their larval stage; The first form was sufficiently powerful, especially with beta-rays to clone their numbers into the thousands, far beyond the original population of SR388.
Raven Beak slaughters all but one of the Thoha, leaving you, Quiet Robe, alive. He brings you back with him and the rest of the Mawkin to ZDR, as well as the Metroid DNA samples his soldiers acquired; A return trip to SR388 is no longer necessary, and Raven Beak is fine with that planet being overrun by Metroids resistant to his control, but otherwise unable to access other worlds. But amidst the chaos, a lone X emerged from hiding while the Metroids were busy fighting the Mawkin, and infected one of the latter. This parasite stowed away, returning to ZDR with the rest of the Chozo.
And without any Metroids on ZDR, it felt safe to reveal itself in Elun and begin infecting the rest of the tribe, resulting in a years-long war and quarantine effort between the Mawkin and X. The Mawkin attempted to clone Metroids using the DNA samples they had, but the X were intelligent and could absorb their victims' memories; They predicted this move, and were able to move quickly enough to destroy all Metroid DNA on ZDR before any of their predators could be cloned. Without any methods to destroy the X short of blowing up the planet itself, all but one of the Mawkin would end up infected -karma- before Raven Beak finally isolated the parasites within Elun, somehow.
There's no DNA samples to create Metroids from, not anymore. And you can't build another Metroid from scratch, not without the DNA of the original SR388 creatures that went into it... But you can definitely build beta-ray emitters. And there are still plenty of Metroid larvae back on SR388 to clone directly, instead of the more roundabout process; So Raven Beak flies the Itorash back to SR388... And finds a bunch of rubble where the planet used to be.
Eventually he puts together that the human warrior he helped Old Bird and Gray Voice hybridize blew up the whole damn planet, finishing what her fellow Thoha started. His plans to conquer the galaxy with Metroids is screwed, they're all extinct with any DNA samples eradicated. That is, until Raven Beak finds out that his "daughter" Samus has Metroid DNA, thanks to the Galactic Federation, and the very X that spawned the Metroids' existence (and yet also delayed Raven Beak's plans by infecting his entire tribe).
And now, after all that effort in creating and then trying to destroy the Metroids, you have to bring them back using the person who helped you destroy them. Or, maybe not... Over your dead body! Which turns out to be literal when an X absorbs your corpse and then helps Samus awaken her Metroid DNA by siccing the remaining EMMIs back on her. How did you even get to this point again???
I feel like this more sympathetic tone towards them could have made Ridley’s appearance in Metroid: Samus Returns a bit more impactful by having him be a sort of narrative symbolism for the use and abuse of the Metroids by higher powers who wanted to play god. Maybe start the game with Samus delving into the desolate, barren husk of a landscape that is SR388. The planet is cold and dead on the outside, dust fluttering about in the wind, harkening back to all the dry, lifeless bodies left behind in the wake of the rampaging Metroids we’ve seen throughout the series. As she delves deeper into the underground cave networks, it becomes clear that, while many have become terrifying, dangerous predators, there is an ecosystem that some that aren’t Ridley may call beautiful. There are creatures that take on different roles in the food chain, with different mutations of Metroids having many different roles in this natural, albeit highly competitive, web of life.
Maybe have some monologues about the tragedy of it all. The capabilities of these creatures are sure to be exploited if ill-intentioned people acquire them, and moving an entire, dangerous ecosystem off world simply not be feasible for a simple Bounty Hunter, even one of such renown as Samus Aran. It’s a very unique dilemma to explore. Either kill an entire ecosystem of innocent creatures, or let them live and possibly end up with your inaction causing hundreds, even thousands of deaths in the long run, all passing on in incredible agony.
Then, all is said and done. An entire biological order has been wiped from existence. The Queen Metroid, which spawned all this blooming life like a goddess of creation, has been slain. With her gone, the possibility of an ecosystem of this type is gone forever. But one Metroid remains. A single, lone hatchling, oblivious to all of Samus’s terrible deeds on this world, innocent and friendly. The possibility still remains. The Space Pirates have already succeeded in asexually multiplying Metroids to orders of magnitude of their original supplies in the past. This one single specimen could make a legion if it falls into the wrong hands.
But this is a child. A lone child, without its mother, sitting in an afterglow of ash and death, with none of its kind left for hundreds of light years. It looks up hopefully to a stoic, alien figure, sigils in its technology baring the mark of the Chozo. Quite familiar, no?
As Samus and the last child of the Metroids leave this barren waste behind, she believes that maybe some good can come of this. If nothing else, she has done some small favor for this weary conscience of her’s.
Then, who else should show to complete the metaphor but the Cunning God of Death himself? Contrasting Samus’s gentle approach with the baby Metroid, Ridley is brutal, shrieking alien obscenities at this frightened child, beating it into submission as it fights back against his taloned grasp. This is the face of heartless control and abuse, this is the face of those who made the Metroids an enemy to life in the galaxy. They used these animals to commit atrocities, like throwing the condemned to a pack of starved wolves. This is what playing god looks like. And now the Hunter must cut him down to size.
Really nice thing about Metroid as a series? The Metroids themselves are both presented as incredibly terrifying creatures with the after-effects of their lifeforce draining being showcased disturbingly, particularly in Super Metroid and Prime 3 (GFS Valhalla, anyone?) yet the overall narrative framing of them still makes it pretty clear that nothing in the series is really their fault, the danger they pose is entirely due to outside factors like the Space Pirates and Phazon. Even though them starting to show up in any given game is usually a sign that you're entering The Hard Part, they're still just creatures at the end of the day and treated very sympathetically; Space Pirates abusing them is specifically called out in some of the Prime 2 scan entries.
