Plug Man

Plug Man (プラグマン) is one of the Robot Masters from Mega Man 9 whose period of use had expired and was scheduled to be scrapped. Plug Man was designed to inspect the quality control in a television factory. He is obsessed with gadgets and loves to browse electronic stores. His main weapon is Plug Ball.

His stage consists of many Yoku Block puzzles similar to those in previous games like Elec Man's and Heat Man's stages. There are also video holograms of Mega Man known as Shadow Mega Man that cause damage on collision.

Strategy
His pattern is really difficult to detect. He will jump around at random times to try to divebomb into Mega Man. At other random times, he will shoot Plug Balls at Mega Man that will ride all over the ceiling. Once he is under the ball, it will drop toward him. Plus, if he lands on Mega Man, he will also take damage. This makes Plug Man a very difficult boss to beat.

His weakness is the Jewel Satellite. It will block all the Plug Balls launched by Plug Man.

Trivia

 * Plug Man is called Plasman (プラズマン, a combination of the words plasma and man) in his concept art. (image) This name was also used in previous concept arts of characters from Mega Man 2 and 3, but none resembled Plug Man.
 * During the ending credits, Plug Man is shown with a hand replacing his plug on his right hand while carrying Capcom bags with Rush. The removal of his plug is probably to make him harmless in case he goes berserk again, or he's able to change his arm into a plug like Mega Man and other robots can turn their hands into cannons.
 * His mugshot looks similar to his artwork since Plug Man's faces are facing straight forward, but his eyes and eyelids have different colors in the mugshot due to color limits.
 * Plug Man is one of two Robot Masters in Megaman 9 designed by Keiji Inafune. As he says in Capcom Unit Blog. Link.
