Wily Machine 3 (ワイリーマシン3号,Wairī Mashin 3 Gō?), also called the Pinbot in the NES Game Atlas, is the third Wily Machine used by Dr. Wily in the Wily Castle to fight against Mega Man. It is the first Wily Machine to use a walking system instead of being aerial.
1st form: Its weak point is the cannon under it. The gun shoots energy balls that spin throughout the screen. The gun is weak to Hard Knuckle and Spark Shock.
2nd form: Its weak point is the dome which houses Dr. Wily's cockpit. Due to its height, Mega Man can only hit him when he goes down to smash, or by using Rush Jet in order to reach high enough to hit him. One can also use Hard Knuckle (as well as a well timed Search Snake), which is the second form's weakness. When destroyed, it is revealed that the Dr. Wily inside of it was a fake, and Mega Man proceeds to the last stage to fight the final boss, Gamma.
The Wily Machine 3 appeared in issue 47 of the Mega Man comic series by Archie Comics, where Mega Man fought it shortly after disabling the Doc Robot. Mega Man noted that it resembled the Wily Walker, Wily's earlier creation that had led to him being banned from work on robotics (a comics-exclusive concept). After defeating it, he attempted to interrogate and apprehend Wily, only to discover it was actually a robot in disguise (which was foreshadowed by it constantly repeating his threat during the battle), although Mega Man noted that the presence of a fully operational control unit indicated that Wily had at one point intended to use it himself. Mega Man proceeded to link up to the Wily Machine to discover the location of Wily and Gamma.
