Wily Castle (Mega Man 2)

This is the complete list of all the stages and their enemies in Wily Castle in the classic Mega Man series, where Mega Man ultimately goes up against his arch-nemesis, Dr. Wily. This list includes Dr. Wily's other fortresses in the Game Boy levels, but not Dr. Wily's Robot Manufacturing Plant, seen in the first Mega Man game and updated for Mega Man Powered Up.
