Skullcrawler

.
Skullcrawlers got their name from their skull-like heads and their crawling locomotions. Their true name is known but unspoken by the natives, and the name "Skullcrawler" was invented by Marlow as he explained their history to Weaver and Conrad.

DesignEdit
AppearanceEdit
Skullcrawlers are large reptilian creatures with only two long forelimbs and no hindlimbs, as well as long, prehensile, serpentine tails. They have long and slender, yet muscular, sturdy bodies. Several aspects of their appearance are noticeably skeletal, particularly their torsos and their heads. What appears to be the "eye sockets" of their skull-like heads are merely empty fenestrae presumably it evolved that way to protect its eyes from enemies: their real eyes are set much further back, with the fenestrae perhaps serving to distract enemies from their more vulnerable eyes and acting as heat-seeking sensory pits. The pupils of their green eyes are horizontal and somewhat resemble those of frogs and toads. The colors of their scales range from dark brown to dark green to a bone-white color.

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 clawed digits in a total of each hand, with the thumb being the smallest digit and the rest of the digits being larger and of the same size, and the adults have a prominent bony spike protrudes out of each of their elbows. The thorny, toothlike structures of their inner mouths somewhat resemble that of a leatherback turtle's. Additionally, they have long, prehensile triple-forked tongues that they can use to grab their prey.

Juvenile Skullcrawlers are easily distinguishable from adults. Their heads are smaller and more sloped. They also possess a more prominently brown skin tone. Adult Skullcrawlers are much larger, with most being almost the same size as Kong. Their heads are more defined, larger, and somewhat angled. Their tails are armed with a form of a club that can be used as a weapon, and they also have distinct bone-like spikes protruding from their elbows.

The Skullcrawlers were designed to act as the "fallen angels" of Kong's kingdom and represent the darker, bleaker aspects of Skull Island.

PortrayalEdit
All of the Skullcrawlers are portrayed by CGI.

RoarEdit
The roar of the Skullcrawler is very high in tone, possessing a raspy quality with a hiss and growl mixed in between. According to supervisor sound designer/editor Al Nelson, the Skullcrawler roar was inspired by the pained squeal of a dying rabbit as well as the sounds of sea lions and squirrels.[1] Some of its sounds were recycled from the Indominus rex from the 2015 film, Jurassic World.

PersonalityEdit
Skullcrawlers are subterranean pack-hunting predators with insatiable appetites that are the results of their heightened metabolisms. They are highly aggressive, as well as incredibly persistent in pursuing their prey. They do however show a high degree of intelligence (as Hank Marlow calls them "crafty bastards"), shown when the largest of the Skullcrawlers refused to devour a grenade-armed Cole and simply swats him away. The smaller Skullcrawlers appear to be naturally fearless, as two of them teamed up to attack Kong despite being smaller and out-muscled.

The largest of the Skullcrawlers appeared to be more intelligent than the rest of his kind. This was seen when he appeared only once Kong was subdued by Preston Packard and when he felt like Earl Cole was tricking it. He also seems to have a hint of sadism as he licks Kong's face maliciously after the giant ape got tangled up in a shipwreck's rudder chain during their battle. This large Skullcrawler was also shown to have a deep desire of killing and eating humans, which was shown several times when he diverted his attention from Kong to James Conrad and Mason Weaver, implying that he had a sense of malice and cruelty. This could also hint that the entire Skullcrawler species is innately malevolent, as Hank Marlow calls them "nasty" and "mean as hell".

OriginsEdit
“ Little is known about the origins of this voracious predator, although its evolutionary purpose is abundantly clear. The Skullcrawler exists to devour, destroy, and dominate. Subterranean in nature, burrowing up through the geologically unstable steam vents across Skull Island, it is as though the Skullcrawler climbed up out of Hell itself.
This terrifying serpentine is a hypervore: a creature with such a hyper-adrenalized metabolism that it exists in a constant state of starvation. Just as a shark must keep swimming to survive, the Skullcrawler must keep feeding, dislocating its own jawbone so to maximize its ability to swallow anything that crosses its path. And within that gaping maw exists a long, whiplash tongue, which the creature uses to ensnare and constrict its prey. Its olfactory system can sense hot-blooded life across huge distances. Once it has picked up your scent, the blood in your veins is like blood in the water.
Perhaps most striking is the beast's fearful visage. A chilling, lidless skull-face peers out through translucent flesh, as two dark and lifeless eye sockets regard their prey with cold, unflinching malice. The patterning of its facial features may be indicative of deimatic behavior designed to threaten and terrify its prey.
We have observed different Skullcrawlers in a wide variety of different sizes. Given the unreachable depths of their subterranean nesting grounds, we have no way of knowing how big these things get, or the pecking order that governs their tribal feeding patterns.
The more we learn about the cultural history of Skull Island from the indigenous petroglyphs we have discovered, the clearer it becomes that the evolution of the Skullcrawlers has long been interwoven with Kong and his fallen ancestors.
If Kong is god of Skull Island, then here comes the devil. „

The Skullcrawlers are a species of super-predator that invaded Skull Island, evolving the role of apex predators in direct competition with the giant ape-like species also inhabiting it. Very little is known about their origins or when they evolved, and they are not completely considered Titans.

HistoryEdit
Kong: Skull IslandEdit
A Skullcrawler was first seen feasting on a dead Sker Buffalo by Kong. Kong was about to confront the creature when he was ambushed by a second one from behind. After a quick battle, Kong ends up subduing and killing both Skullcrawlers by stuffing one's head into the ground, breaking its neck, and smashing the other's skull with a devastating stomp.

Another Skullcrawler ambushed Jack Chapman and a Spore Mantis, but went for Chapman and ate him alive while the Spore Mantis managed to escape. The same Skullcrawler then showed up in the boneyard and vomited Chapman's remains. When William Randa attempted to make his camera work, he was devoured by the Skullcrawler, who then tried to attack the group. Randa's camera started to flash inside the predator, which started to aggravate the monster.

The Skullcrawler then started chasing Weaver but the group retaliated using flamethrowers. The creature batted a crew member with its tail onto one of the Kong skulls, causing his backpack to detonate several canisters of toxic gas. The Skullcrawler started to grow more relentless and disturbed a flock of resting Leafwings, which then turned their attention to attacking the group. Conrad managed to kill some of the flying creatures using Hank Marlow's katana. The Skullcrawler then set its eyes on Conrad and Reg Slivko, but Weaver rescued them by tossing Conrad's lighter at one of the subterranean vents, creating an explosion that killed the Skullcrawler on the spot.

The largest of all the Skullcrawlers was awakened due to seismic explosives dropped onto Skull Island along with the rest of his kind, and after Kong was incapacitated by Packard, he let his presence be known by emerging out from the water. Then he attacked the weakened Kong, quickly rendering the ape unconscious before turning his attention to the humans. As he chased Conrad and the other survivors of the research expedition sent to Skull Island, Earl Cole tried to sacrifice himself along with the beast by arming several grenades before having the massive creature try to eat him. However, the monster didn't take the bait and batted him against a mountainside as the grenades went off, killing him.

As the large Skullcrawler finally reached the rest of the crew in a marsh, Kong appeared in time to stun the giant reptile with a large boulder, enabling the crew to run to safety. The Skullcrawler then returned his focus to Kong, pouncing on him and biting his throat. Kong and the Skullcrawler continued to brutally wrestle, pummel, and bite each other until the Skullcrawler threw Kong into a shipwreck with his tail, where the ape became entangled in the chains. With Kong subdued in the wreck, the Skullcrawler was about to kill him when he's fired upon by Houston Brooks and the other humans. He then returned his focus to the humans and approached them, giving Kong the chance to free himself from the chains.

As he approached the crew once more, the monster's right eye was destroyed by a flare fired by Weaver, and Conrad lured him away from the crew on their boat. This allowed Kong to use and swing the propeller of a wrecked ship at his adversary like a medieval flail, which caught the beast in the shoulder and allowed Kong to pull the Skullcrawler back toward him and resume their fight. Kong continued to wrestle the creature and threw him into the side of a cliff, causing Weaver to fall into the water below.

As the Skullcrawler continued to attack Kong, the ape uppercut him with the ship's propeller, slicing the monster's throat wide open and seemingly killing him. As Kong saved Weaver from drowning, the Skullcrawler pounced at Kong once more. After coiling his tail around Kong, he wrapped his tongue around the ape's arm, pulling it down his gullet in an attempt to devour Weaver as she's clutched in Kong's hand. After a brief struggle, Kong tore out the creature's internal organs through his mouth, killing him instantly.
