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 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 once again runs a store, where he would make parts for the player in exchange for Bolts/Screws. 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.

In Mega Man 10, when the player is using Mega Man, Auto assists Dr. Light rather than Roll as she had the Roboenza virus at the time. When the player is using Proto Man. Auto runs the shop by himself, and appears to be wearing a Mettool helmet. Humorously, Auto is not identified as such and his name is displayed only as "????". Tango also appears in his shop, napping or playing on the counter.

Trivia

 * In the Japanese versions of the games he appears in, Auto often ends his sentences with -dasu (- ダス), a nonsense word that is his trademark.


 * Auto regularly appears in his own gag comic feature in Rockman Megamix. The plot always involves Auto inventing some new type of Robot Master to help Dr. Light, but despite his good intentions the robots all inevitably go haywire and explode spectacularly.


 * Auto makes a small cameo in Volt Catfish's introduction scene in the PlayStation and Mega Man X Collection versions of Mega Man X3.


 * Auto seems to have an affinity for Mettool helmets. He is seen wearing one in Proto Man mode in Mega Man 10, and he tries to give Mega Man one at the beginning of Mega Man 7, and states he prefers it to Mega Man's normal helmet.


 * He seems to greatly respect Mega Man, as seen in his Mega Man & Bass card and in Mega Man's ending in the first arcade game where he is seen fanning Mega Man.
 * RT-55J, a mini-boss that protects an armor capsule in Mega Man X and Maverick Hunter X, seems to be related to Auto in some way.  RT-55J has a similar color scheme to Auto, including red orbs on its body and a red orb as an eye, yellow shoulders, green armor, and gray piping for its upper arms and legs.  It is theorized that it is actually Auto given an upgrade by Dr. Light and given the task of protecting the Capsule.  Adding to that, RT-55J's torso resembles Auto's head, and RT-55J is a possible reference to Auto's Japanese name, RighTot.  However, there has never been any official confirmation of this, and it is likely that RT-55J is more of a tribute to Auto rather than an upgrade.
