Rockman World

A series of Mega Man [ロックマン] titles released on the Nintendo Game Boy. The English-titled releases were made distinct from their NES counterparts with the use of Roman numerals. Essentially abridged versions of the main franchise, the Rockman World games introduced "Mega Man Killer" robots such as Enker, but largely adopted components from the NES series such as robot masters and their respective level designs.
