Giant Anaconda

Giant Anaconda is a snake created by Netflix that first appeared in the Kong: King of the Apes episode Snake in the Grass.

Kong: King of the Apes
The Giant Anaconda lived the Amazon, but was driven north due to deforestation. While swimming in a river, the Giant Anaconda came across a girl, who it tried to eat. It was soon attacked by King Kong, who was in turn attacked by Bionobots, which the two fight together. During the fight, Kong becomes distracted and the Giant Anaconda is flown away in the claws of a pterodactyl Bionobot. In the laboratory of Dr. Richard Remy, Giant Anaconda is outfitted with Bionobot armor that puts it under the control of Dr. Remy. It then fights Kong on Alcatraz island by constricting him and electrocuting him. Kong is able to subdue the creature by having it swallow a battery to overcharge it. When it is out of Remy's hands, Lucas Remy and Doug Jones then return the Giant Anaconda to the wild.

Electrocution
With its Bionobot armor, Giant Anaconda can send an electric shock through its body and into its prey
