RB133 Auricrusher

The RB133 Auricrusher is a robotic enemy in Metroid Prime: Federation Force. Its only appearance is in M18: Hightower, where numerous units will spawn to destroy the Drill the Federation Force is protecting. As it approaches the Drill, its own drill will activate and the machine will continue to the base of the Federation Drill. The machine moves very slowly however, so it can be destroyed before it even reaches the Drill.

They are similar in name and appearance to the RB176 Ferrocrusher, a power loader fought as a boss in Metroid: Other M. This could suggest they are related in some way, perhaps being made by the same manufacturer, which could be the machine race that abandoned Talvania. Both of their names may also refer to ferrum and aurum, the Latin words for iron and gold.
