The hopper bot is an enemy in Jak 3, part of the KG Death Bots. Resembling the Metal Heads' hopper, the hopper bot is a small, water-proof, crimson-colored robot which has a hopping locomotion, respective to its name, usually found in groups of other bots. They are found in the sewers, usually following or appearing before bigger KG death bot groups. They often ambush their target by jumping out of water en masse.
Hopper bots do not appear to have any attacks besides jumping their opponent. Due to their weak armor they are easily destroyed, so a lower-tier mod is recommended to save ammo. In example, a single Scatter Gun shot can take out most hopper bot groups in one.
