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 incredibly tough, resisting brutal asteroid-speed asteroid landing on Earth or powerful energy weapons. They also possess vast superhuman strength, being able to tear through a titanium armored room with little effort. They are able to fly and to secrete an adhesive web-like fluid to immobilize other creatures. They are infamously known as interstellar terrorists. In "The Irritable Bow Wow Syndrome", a particular Charnock came to Earth in search of a Void Density Core, a small sphere-like device capable of acting like an artificial black hole for waist management purposes only, but was outlawed due to intergalactic terrorists. He needed it to use on the Chrysler Building, which is in reality a launch pad of the Relserks, a peaceful alien race and enemy to the Charnock. According to K, the Charnock wanted to keep the Relserks from ever going home.

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