Which is the most ruthless alien in all filmdom

I am leaning towards the thing from John Carpenter's The Thing because of it's ability to assimilate any organic thing it comes in contact with. The alien from Alien is also right up there as well. Any suggestions????

Either the Xenomorphs or the Arachnids from Starship Troopers, cause of the sheer ammount of them.

But like you said, The Thing can imitate anything so probably The Thing.

Ming the Merciless, since he has a synonym for "ruthless" in his name

As far as being Ruthless. Off the top of my head i would have to say the Xenomorph. The Xenomorphs actions and intent is based on survival. They Pursue their prey relentlessly because they have to. .

I'd have to go with Xenomorphs, they don't care what they kill...as long as it means they survive.

Hey what about KLINGONS 🤘

Well, the aliens that made podpeople in all the "body snatcher" films were most succesful in doing what they set out to.

human beings.....

Kang and Kudos - Not from the films but still pretty nasty customers.

The parasites from Meatball Machine.

They drill bio-armor into people to kill each other in a bloody massacre all in the sake of a fun recreational game.
