Pump Man

Pump Man (ポンプマン) is a Robot Master from Mega Man 10. He can create a shield of bubbles around himself and release them at several directions.

Pump Man worked at a wastewater treatment plant, purifying the water that comes through. He also volunteers his time to wash graffiti off of walls in the neighborhood. Pump Man has also been described as a "neat freak."

Strategy
Pump Man starts off by creating Water Shield. He then jumps around trying to tackle you. He eventually fires off his Water Shield.

On Easy Mode, Pump Man's Water Shield only has four bubbles instead of eight.

On Hard Mode, Pump Man has an extra attack in which he tosses his Pump Handle at you like a boomerang.

His weakness is Thunder Wool, as it can hit him multiple times, pierces, and destroys his shield, though make sure it's high enough he can't cancel it out.

Trivia

 * He and Chill Man are the only Robot Masters in Mega Man 10 to have faces, the others just have black slits with eyes in.
 * Despite having a cannon in his right arm, he does not pump any of the Water Shield Bubbles from it.
 * Pump Man is a little reference to Clown Man (The long arms) and Dive Man, also, is the third robot master that use pure water, after Bubble Man and Aqua Man.
