Karakuri Maito Gai
Might Guygatron is a giant robot hidden in the back of the Hokage Monument behind a stone face of Might Guy. It looks exactly like Guy himself and can be used to perform the same techniques as Guy also.
Despite being called a robot, it is actually more of a giant puppet, being controlled through the use of chakra threads and, in the case of Lee, a piano wire to work the eyebrows.
Whilst initially coming across as both bizarre and useless, through combined effort of its users, Guygatron pulled off a maneuver similar to Guy's Shimura-Style: Secret Strike, managing to defeat even Manda, Orochimaru's fierce personal summon.
