Warbat

Warbats (ワーバット Wābatto) are winged snake-like monsters who appear in Legendary Pictures' 2021 film Godzilla vs. Kong. Massive predators of the Hollow Earth, they menace Kong and the Monarch-Apex Cybernetics expedition shortly after their arrival.

Personality
Monarch classifies the Warbats' behavior as that of "destroyer[s]", along with King Ghidorah, Rodan, Scylla, MUTO Prime, Camazotz, the Arachno-claws, the Hellhawks, Mechagodzilla, and the Skullcrawlers.

Godzilla vs. Kong
No sooner had Kong and the Monarch-Apex Cybernetics expedition begun to explore the Hollow Earth than they were ambushed by a pair of Warbats. The first sank its teeth into a HEAV, destroying it instantly. It circled around for another strike, but just before it could bite the HEAV carrying Dr. Nathan Lind, Dr. Ilene Andrews, and Jia, Kong grabbed it by the tail and slammed its head into a sharp rock, killing it. He swung its corpse around to bludgeon the second Warbat. The serpent quickly recovered and constricted him, covering his face with its hood. Lind ordered his HEAV to launch a missile barrage at the Warbat. In its agony it loosened its grip on Kong, and the ape made it pay, slamming it repeatedly into the ground and pounding it to death with his fists. Ripping off its head, he spent a few moments slurping its innards as the humans watched in disgust.

Physical capabilities
Warbats can use their membranous wing-like hoods to both fly and glide through the air. They are agile fliers and display excellent maneuverability. The average Warbat can move through the air at a maximum speed of 72 mph, or about 115 kph, and glide at 46 mph, or about 74 kph.

They are also quick in combat, able to coil the entire length of their bodies around prey in seconds. Using their wings, they can utilize the fingers as limbs in order to quickly crawl about, as seen when one swiftly repositioned itself using its fingers to face Kong after he knocked it to the ground. During its fight with Kong, the second Warbat managed to latch onto and wrap around him with its snake-like body, then attempted to suffocate him with its wings.

The Warbats have an average bite force of 5,900 pounds per square inch, and can strike at an opponent at speeds of 121 miles per hour. The first Warbat was able to destroy a HEAV using its 14-foot long fangs.

Durability
Kong killed the first Warbat by slamming its head into a sharp rock. The second Warbat loosened its coils when it was hit by a HEAV's missiles, allowing Kong to break free and quickly dispatch it by repeatedly slamming it into the ground and bashing it with his fists.

Venom
According to the Japanese theater program for Godzilla vs. Kong, Warbats are highly venomous and can inject some 9,800 gallons of venom (or 37,000 liters) into their prey in a single bite. The description on the back of the packaging for Playmates' 6" Warbat figure also describes the creatures as having venomous wings. This trait was not explicitly demonstrated in the film.
