Skullcrawler

Skullcrawlers スカルクローラー (Sukarukurōrā) are giant reptilian Kaiju that appeared in Kong: Skull Island.

Name
Skullcrawlers got their name from their skull-like heads and their crawling locomotions.

Appearance
Skullcrawlers are large reptilian creatures with only two long forelimbs and no hindlimbs, as well as long, prehensile, serpentine tails. Several aspects of their appearance are noticeably skeletal, particularly their torsos and their heads.

Their heads closely resemble those of Mosasaurs such as Tylosaurus, and their jaws possess two rows of serrated, razor-sharp teeth. The Skullcrawlers have four digits in total of each hand, with the thumb being the smallest digit and the rest of the digits being larger and of the same size. Additionally, they have long, prehensile triple-forked tongues that they can use to grab their prey.

Personality
Skullcrawlers are subterranean pack-hunting predators with insatiable appetites that are the results of their heightened metabolisms. They also regurgitate anything that their stomachs cannot digest.

Kong: Skull Island
One Skullcrawler was first seen ambushing Jack Chapman and a Spore Mantis, but it went for Chapman and eats him alive while the Spore Mantis left the area. The same Skullcrawler then showed up in the boneyard where he regurgitated Chapman's remains. William Randa attempted to make his camera work, but he was devoured by the Skullcrawler, who then tried to attack the group. Randa's camera started to flash inside of the aggressive predator, which started to aggravate him.

The Skullcrawler then started chasing Mason Weaver, but he was attacked by the group using flamethrowers. Psychovultures then attempted to assist, but James Conrad killed some of them using Hank Marlow's katana. Weaver then tossed a lighter at the Skullcrawler, which ignited fumes from the subterranean vents, causing his body to detonate, killing it for good.

Burrowing
Being subterranean in nature, Skullcrawlers are capable in using their limbs burrow deep into the earth.

Durability
Skullcrawlers are very durable, as they can withstand the searing heat of a flamethrower, and they are only dazed when Kong slammed at them with a boulder or hit them with a tree branch.

Physical abilities
As the apex predators of Skull Island, Skullcrawlers are fearsome and deadly in battle. They use their teeth and claws as their primary weapons, and their tails can swat humans through the air with a single hit.

Prehensile tails
Skullcrawlers have long, prehensile, serpentine tails that they can use to constrict their victims.

Prehensile tongues
Skullcrawlers are equipped with long, prehensile triple-forked tongues that allow them to grab their prey.

Heightened Metabolism
Skullcrawlers possess accelerated metabolism, which caused them to live in constant starvation.

Trivia

 * The Skullcrawlers' design have been influenced by the Two-Legged Lizard from the original 1933 King Kong film, along with Sachiel from Evangelion, No-Face from Spirited Away, and Cubone from Pokemon.
