The Strelac is one of the "complete mutation" forms that the J'avo will morph into once injured enough. A scale like armor covers its head while several horns lie around its head and neck. It also sprouts a tail, and somewhat resembles a frilled lizard. Despite its large head, a Strelac is one of the fastest Chrysalid mutations in the game.
The Strelac's eyes are positioned asymmetrically, with only a single eye on the left of its head and three eyes on the right. The Strelac also seems to possess only one arm, giving an appearance of a tripedal creature.
