A cylindrical, bipedal worker robot with a very simple AI program. These robots are an indispensable, standardized model designed by the Chozo to take on a number of tasks. Their mobility is quite slow, but their usefulness is completely versatile. Depending on their programming, they can be tasked with reconnaissance, cleanup, transport, and destruction. They are originally spotted in the Wrecked Ship, where their energy is completely drained and they are immobile. After Phantoon is defeated, the Wrecked Ship robots spring back to life. They do not intentionally want to attack Samus, but have malfunctioned to attack anything that moves.
