Species Location Weapon Abilities The metal head bat is an enemy in Jak 3 which is only found in the mission "Destroy eggs in nest" at the Metal Head cave. The bat is a blue-colored metal head with two pairs of very long wings and three small pairs of legs. There are also three little pairs of "stingers" behind the legs serving an unknown function. They have a lengthy body ending with a long tail. Bats dwell in holes in the ceiling, and if an enemy is detected they will swarm out and attack by firing blasts of dark eco.
