|Behind the Scenes|
The "alien agents" are a race of sapient humanoid beings from the Arrival films.
The alien agents are a race of conquerors bent on terraforming Earth by disguising themselves as human beings and building powerplants that emit green house gases in order to raise the world's temperatures to make it more like the alien's own homeworld.
Things that are cold like liquid nitrogen and freezing places, like the arctic and meat lockers weakens them and knock the aliens into a coma. Some fan theories suggest their skin is only as thick as three sheets of paper stacked on top of one another.
