The psionic bends space around itself, making it's ship invisible to all automated defenses.
Then assuming all manned vehicles also fail to stop the alien, we have learned the alien invaders manipulate space itself and are potent psionics.
10% more psionic power allows it to sense lesser psionics anywhere in the galaxy, while hiding it's own presence from detection by the weaker psionics.
If we hold this to be true. I argue the contrary, given that more power makes things more visible, but ey, reality warping ayy lmaos are dangerous so let's assume the worse. My proposition proposes that the vials be divided between 5 people, which gives the maximum psionic potential over the longest period of time - literally only limited by the lifespan of the psionic humans in question. Assuming that the psionic ayy lmao is capable of infiltrating planet Earth without any of the 5 psionics from noticing that something more powerful than them has arrived, how on Earth (or indeed, out of Earth) would your proposal be better?
Analyzing this, we can have two scenarios. One wherein the five psionics have prepared for the full 5 years to mobilize all of mankind into a giant war state with screening and bureaucratic surveillance. I don't care if the psionic ayy lmao can make itself invisible, I want to know where its papers are, otherwise all glory to Arstoska, the ayy lmao has been found
Moreover, let us assume that psionic power is not additive and that contrary to human naturte, cooperation does not drastically multiply the power of weaker individuals. How is holding vials in reserve going to help at all? If we have simply one person holding onto the vials waiting for an invisible psionic material warping alien to show up only to use the vials then, that alien is just going to kill the human who cannot have any chance of sensing the psionc whatsoever, with that ayy lmao then taking control of all the vials. Also hell, even if each individual psionic cannot sense the one alien psionc,
they will know when one of their own goes silent.
Let us assume this ordinary human is somehow capable of sensing the psionic and drinking two vials before the ayy lmao kills him. This human becomes a one man army, and is capable of killing the ayy lmao before it runs away. The increased psionic potential runs out, as it is only temporary. We're now down to 3 vials, and one psionic at standard strength, having killed only ONE alien. The aliens will now know that there is a human capable of outmatching their psionic potential on a temporary basis. There is absolutely nothing stopping them from wiping out all of humanity around this one human, there's no way in hell this human can stop the aliens from wiping out every human centre across the globe where this one psionic is. As soon as they realize this one psionic is only more powerful than them temporarily, they are going to launch their full assault, all of mankind's conventional communications will be wiped out, the psionic will be killed and all of mankind will be at the mercy of this extragalactic invader.
It makes zero sense whatsoever to be competing with an alien invader on their strengths when the aliens are objectively superior to you in every capacity. You need to compete on the strengths of humans.
Conventional human reinforcements are incapable of perceiving the psionic as a threat or anything out of the ordinary. Psionics basically trump all non-psionic defenses.
Then the alternative is having one human who is capable of perceiving the psionic threat for four temporary instances. If there are more than four aliens, of if the aliens attack outside of those four instances when one human is overpowered, mankind is defenceless and will certainly perish defenceless. On the contrary, having five psionics direct the defence, it doesn't matter if the humans cannot perceive the alien - the psionics can, and can direct the reinforcements to kill the aliens.
The alien does not kill it's victims immediately. Upon overwhelming their inferior minds, it takes control of them and forces them to act normally until it has finished neutralizing all potential threats.
The problem is that this then creates a very visible blackspot upon the already established illuminati network - it would be akin to a city full of lights, with one district suddenly having a blackout, a blackout visibly spreading in a certain direction. Normal human information analysis would be able to reveal the geographic locale of the alien, especially with the five psionics spread around the Earth - even if each individual psionic cannot sense where the alien is, because its magic psionic powers means it is more powerful than Sonic OCs, they can see where the humans formerly under their control have blacked out of the grid.
Psionic powers are not additive in that fashion. It would be like 4 guys with guns against 1 guy with a tank. Those 4 guys are going to be wishing they had that temporary army.
Whose to say that they are not? This alien has 110% the power relative to one individual with one vial at 100%. Someone who is 10% stronger than me and 10% tougher than me cannot help but be overwhelmed if there are five of me. It is like a beetle that is 10% larger than and vastly tougher and stronger than any individual ant. Yet two ants is enough to kill the beetle in safety, five ants is overkill. This is again assuming that all of humankind is ineffectual against the enemy, which is a big assumption to make -
the note explicitly commanded us to mobilize humanity, one of the foremost details is that humanity will be of paramount importance to the defence of humankind.
Put another way, I am not at all interested in wasting a limited resource merely defeating one tank, when I am mobilizing the entire species and sum total of human civilization against an enemy that probably has multiple tanks and must be defeated asymmetrically.
So, you're handed a weapon and presented with an overwhelming enemy, and you refuse to use the weapon on the grounds that it might be what the enemy wants you to do? You're definitely screwed if you don't use the weapon, so you gotta take that risk.
No, I'm handed a weapon and presented with an enemy I don't know. I don't know what they want, what their capabilities are, whether they exist, what form they exist in, are they psionic, are they a swarm of critters, a mechanized borg, an extragalactic colony of long lost humans, a bunch of FTL pacifists etc.
I'm given five tools. Taken together, these tools can either provide an invaluable and permanent benefit to the defence of mankind, providing a communications network that cannot be destroyed in the high likelihood our satelites are wiped out and power grid is compromised. Moreover the actual consolidation of humanity and mobilization of humanity is a daunting task in of itself, having five full-time psionics working on all the corners of the globe's most powerful leaders would allow for the quickest consolidation and mobilization in the meagre five years provided.
Thus I can choose. Provide an invaluable utility to mankind which will keep it united through the apocalypse, or I can create a weapon which will last a few days against a threat which is a
planetary invasion, which suggests an incredibly protracted campaign - how can you be thinking of creating temporary supermen out of a limited resource when the enemy can simply wait in space for your ability to run out? Rofl
