Auto

Auto, known as Rightot (ライトット) in Japan, is a character from the Mega Man classic series. Even though he was not introduced until Mega Man 7, it is clear that he has been with Dr. Light for a long while. He is seen to have a large car, and is the mechanic for Dr. Light. Eddie is almost his pet. He creates items for Mega Man by using Bolts/Screws. In the Japanese version of Mega Man 7, he appears randomly in place of Dr. Light or Roll when Mega Man gets a weapon, making funny comments. 

In Mega Man 8, he appears as an aid in the Rush Jet sections, using a cannon to attack enemies. In Mega Man and Bass he ran a store, where when the player brought him Bolts/Screws, he would make parts for him. In the arcade games, he appears in Mega Man's endings.

In Mega Man 9 he returns to his role of running a shop, assisting Roll. He takes screws as currency. He's also responsible for restoring Rush's Rush Jet upgrade after Mega Man beats five Robot Masters.
