AU where Calmèque survived the destruction of the base along with Ménator, and other Olmecs (among which the Olmec lieutenant who wears the green cape, medics, the little guy in charge of maintaining the drainage tank, and other Olmec soldiers).
Ramblings about this AU below:
My headcanon is that Olmecs are sensitive to light (which is why they move or attack once night has fallen).
That's why they opted to build their new base in the heart of another mountain.
There, they explored the most powerful energy source of all: nuclear fusion. In this way, they were able to reproduce on Earth the reactions that take place inside the sun, creating their own “sun”.
I see Calmèque as one of the Olmecs with a more developed scientific mind and curiosity. While Ménator focuses on cellular biology to extend the Olmec's lifespan, Calmèque focuses on the study and understanding of high-temperature plasmas and their confinement by magnetic and electric fields.
A century later, the Olmecs created the first nuclear fusion reactor, generating colossal amounts of energy that satisfy their energy needs. Thanks to this, Ménator is able to electrically stimulate the fusion of two previously atrophied and dysfunctional Olmec reproductive cells (I headcanon the Olmecs as hermaphrodites, in which both reproductive systems progressively atrophied over time, hence the Olmecs are sterile). This way, they are able to ensure their descendants (although the embryos develop in incubating machines) and secretly become the most developed civilization on Earth :)
PS: to make Calmèque's outfit I was inspired by the clothes worn by the Olmecs in one of the new seasons (which I've never seen, but anyway).
More than ten years later, here I am again, giving Calmèque and Ménator the love they deserve.
Some things never change...
I can't help thinking that Ménator died in Calmèque's arms, who, without noticing his death, kept desperately asking Ménator to give him the orders to remedy the irremediable.
