Sub-Cities

The Sub-Cities are three subterranean cities in Mega Man Legends where the Prototype Anthro Units lived. While inside the Main Gate, Mega Man Volnutt unlocked the entrances to the Sub-Cities, which appeared on the surface of Kattelox Island. Each Sub-City is protected by Reaverbots and contains one of the three keys needed to open the Main Gate's Central Gate, which has been automatically locked by Eden and required manual override through the use of the keys.

Old City
The entrance was blocked by the warehouse in the Old City. After finding the Bonne family inside the warehouse, the warehouse is destroyed in the battle between Mega Man and Theodore Bruno, allowing Mega Man to find the Sub-City's entrance.

This Sub-City is protected by Karubuns, Arukoitans, and Orudakoitans. It contains the 'Watcher' Key.

Downtown
This Sub-City is protected by Karubuns and red Sharukurusus. It contains the 'Sleeper' Key.

Uptown
This Sub-City is protected by Guynie Toren, a large Reaverbot that releases Red Horokkos and green Sharukurusus. It contains the 'Dreamer' Key.
