Ra Moon

Ra Moon (ラ・ムーン) is an ancient super computer that Dr. Wily found three weeks before the beginning of Super Adventure Rockman, and revived Wily's Robot Masters from Mega Man 2 and 3. It crashed in ancient times while every cave man but one ran away. He was brave enough to go up to it and somehow woke Ra Moon up. A war that occured some time afterwards was all in front of Ra Moon which turned it evil, as well as burrowing itself underground.
