Flash Man

Flash Man (フラッシュマン Furasshuman) is a Robot Master from Mega Man 2 created by Doctor Albert W. Wily to challenge the everlasting idea of controlling time. His Special Weapon is the Time Stopper, a unique system that allows him to stop time in his vicinity for brief periods. To supplement his attacking abilities, he is also equipped with a rapid-fire buster on his right arm. The eight Robot Masters from Mega Man 2 have built-in devices that make them immune to the Time Stopper, but Quick Man's device has a flaw, making him vulnerable to it.

In combat, Flash Man can stop time to immobilize his opponents, before attacking them mercilessly with rapid barrages of shots from his buster while they cannot move. To his enemies, Flash Man appears to be moving at light speed or teleporting. It is believed that this ability is a perfected form of what the later-introduced Time Man was capable of- because unlike Time Man, who could only slow down time with Time Slow, Flash Man can stop it completely.

Trivia

 * Flash Man was the only Mega Man 2 Robot Master not to be in Captain N: The Game Master. He was also the only Robot Master from Mega Man 2 other than Bubble Man to not make an appearance in the Mega Man animated series.
