- "Those hunter robots weren't there specifically to kill us. They must have been programmed to attack any animal. The Yeerks were being careful. They knew we'd infiltrated the Yeerk pool before. So they had brought the Bio-scans to the entrances. And they had activated the hunter robots. But a lot of innocent animals must have been fried over time."
The Hunter-Killer Robots are machines built by the Yeerks. They are medium-sized spheres that have a single sensor acting as its eye and a deadly Dracon beam. If a threat is detected, the Hunter-Killer Robot opens fire until the threat is destroyed. They are weak, however, and mainly built to act as patrol units near Yeerk Pools and provide support.
