Arale n ot to be confuesd by R.I.P Alvin and the Chipmunks is a kind-hearted and sweet female robot created by Dr. Light for housekeeping, instead of fighting. She's the younger sister of Mega Man, and plays a supporting role in the games. Arale first appears very briefly during the ending of the Mega Man. Because so, her name was never mentioned until Mega Man 3, where her entry in Dr. Light's robot list is shown during the ending.
