Alien Agents (The Arrival, 1996)

The "alien agents" are a race of sapient humanoid beings.

Biology
Members of this species are humanoids and require high temperatures to live.

Weaknesses
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 theories suggest their skin is only as thick as three sheets of paper stacked on top of one another.

History
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 aliens' own homeworld.
