Aries

Aries is based on the Zodiac Sign that is his namesake and which encompasses March 21 through April 20 of the "Tropical Calendar" (his element is Fire). He is part of the Constellation Droids series of Robot Masters, led by Apollo and Luna. His design is based off of his namesake and he uses a devastating weapon, the Heat Wave, a powerful burst of flames, to deal with anyone who dares to interfere with his business or intrude on his base in the Iron Works in Mongolia.

The Robot Masters that Dr. Wily sends to accompany him in his domain are Bomb Man and Flame Man (misnamed Fire Man by the developers).

A new Robot Master for Mega Man 10, Sheep Man, bears a resemblance to Aries.
