Charnock

The Charnocks are an extraterrestrial species which can travel through space without spaceships, by hijacking asteroids. Their skin is desiccated when entering the atmosphere, after which they mold it. They are infamously known as interstellar terrorists and are able to fly and to secrete an adhesive web-like fluid to immobilize other creatures.

In the movie MIB: International, Ariana Grande's species is listed as Charnock in the surveillance sequence when Molly enters the London HQ.
