Auto debuted in Mega Man #9, where he, Rock, Roll, and Dr. Light give a goodbye party for Mega Man, as Rock will no longer need to fight due to Dr. Wily being no longer a threat. Auto tries to make him change his mind as he is a big fan of the blue hero, but isn't successful. However, the party is interrupted by Quick Man, who attacks everyone and informs them of Dr. Wily's return, and Auto is happy that Mega Man will continue being an hero. Auto used to run a shop, but as Rock is often busy as Mega Man, Auto was called to assist Dr. Light in the laboratory.
