Shadow Man

Shadow Man (シャドーマン Shadoman) is a very stealthy and powerful Robot Master, and is themed around ninjas. He has even been nicknamed the "Menace of Mega Man 3" by some fans. Dr. Wily built him a giant frog robot that he can ride on (a reference to the association of ninjas with frogs). He is a master of ninjitsu, and guards his fortress well.
