Tesla

 The Tesla is a type of Manpig, a creature created by Oswald Mandus' machine through the use Compound X and a mix of human and pig DNA. Unlike the other manpigs, the Wretches and Engineers, the Tesla has been subjected to so much Compound X that it is unhinged from reality, allowing it to flicker in and out of existence. It is stated that it phases between our world and the other place. Rumours persist that the other place is the home dimension of the Kaernks

The Tesla is a monstrously large mutated pig that can move both quadrupedal and bipedal, similarly to Engineers. It also has many electrical devices across it's body, making it easy to locate in dark areas. It's strong enough to kill a man in one strike.
