Aqua Drones are Sentry Drones that have been designed for underwater use. They are similar to their Sentry Drone cousins in terms of A.I. and arsenal. The Space Pirates were unable to shield them from electrical attacks, making them vulnerable to the Wave Beam. They can be found in the wrecked Space Pirate Frigate, Biohazard Containment. Once she leaves the room, Samus will never encounter them again.
