The Rohkor Beetle (called the Goliath Beetle in the E3 2015 Trailer) is a boss in Metroid Prime: Federation Force. It is a large creature that appears on Bion. The Federation Force is tasked with killing this creature before it can destroy an important unmanned probe in M12: Last Stand. A warning will be issued for every 100 meters the Rohkor Beetle gets toward the probe.
To open its mouth and damage the creature, the Force must first destroy its four knees. After all of its knees have been destroyed, the Force can fire into its mouth. If the Rohkor Beetle is hit with a Freeze Shot, its whole body will freeze aside from its mouth. Its attacks consist of a laser beam fired from its mouth, gas, and spawning Fire Griptoraxes and Fire Shriekbats. It will also fire "Rohkor Pods" that spawn Fire Hoppers. There is a Cannon in front of the probe that can be used to attack the Beetle.
