An amphibian take on the Hunter series, the "γ" model has no eyes or teeth. Instead, it has a large mouth that allows it to swallow its prey whole and small claws on their webbed hands.
Unlike the previous frog-based experiment - the Lurker - they retain the increased intellect due to previous Hunter research. However, due to their amphibious nature, they are exceedingly difficult to transport and maintain. Additionally, another factor that adds to their weaknesses is the fact that they cannot survive in dry air or heat for extended periods of time and thus must be kept in strict watery environments only to ensure its survival, so at first they were not meant to be mass-produced.
