The Large-Sized Sharukurusu only appear in the Colossus once it has been activated. They normally hang around the lower level, but may on occasion wander up to the upper level area of the Colossus's head.

These Reaverbots will rush forward toward any intruder, using their momentum to deliver a deadly blow as they thrust their sharp claws forward.

Even when defeated, more will be generated through two portals on board the Colossus.
