The Blue Aliens are the eponymous main antagonists of the 1988 John Carpenter film "They Live".
Who Are They and Why Are They Evil?
These beings came from outer space and want to control the wealth and political powers of Earth. They were able to take over by using a giant satellite dish that will make the blue aliens look just like ordinary people to regular humans.
The blue aliens want money, political power and sexual intercourse. Their primary method of obtaining all three are advertisements that also deceive humans due to the giant satellite dish. These advertisements seem very bland and non-surprising with all its pictures and images as there are only a few words or even no words at all. That's how the advertisements were convincing to the humans. These are the advertisements:
They also have the power to teleport using a device on their arms. The device also works as a communicator.

Then there are humans who work for Blue Aliens. How did they come into contact with the aliens is unknown, but they work for aliens' benefits. One of the human collaborators states that by aiding the aliens, the humans are given the kind of life they could only dream of having. Among the most successful collaborator is a woman named Holly Thompson: by aiding the aliens she is given an assistant director of Cable 54 Station (the source of Alien's brainwashing satellite dish), hefty salaries and luxurious home.
They Live (1988)
The film's main protagonist Nada found a pair of sunglasses that exposes the aliens' true faces and after yelling out loud in a grocery store full of aliens that he knows their secret. He then killed the police officers who were alien, then took their guns and started killing several of the aliens in a bank declaring, "I have come here to chew bubblegum and kick ass. And I'm all out of bubble gum."
At the end, Nada destroyed the satellite dish that made the aliens look like regular people. He unfortunately died in the final battle between him and a group of armed aliens on a helicopter. With the aliens' true faces exposed, the humans quickly panicked while the aliens (who didn't know the satellite dish was destroyed) asked them why they are traumatized. This included two aliens who were broadcasting the news or criticizing movie violence, several aliens at a drinking bar and an alien who was having anal sex with a naked girl.
