The Hunter is inspired by the Predator from the Predator movies, and once was the Predator in the Old Beta.
The Hunter has armor very reminiscent of Predator armor, as it has a plasma caster that is never used, and a face mask. It has netting over it's skin covering most of his body, and a large armor plate on his left shoulder.
The Hunter's ability is too cloak, turning him fully invisible. Along with this, he has thermal vision.
