A very stealthy and powerful ninja-themed Robot Master created by Dr. Wily in the Mega Man Classic series, Shadow Man 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. Unlike most Robot Masters, Shadowman was not built by Dr. Wily, but was origin was unknown and is believed to be alien off origin, the only known fact is that he was remolded into his current form.
