Equipped with many useful instruments and devices, Mechanic Lightan serves as the Lightan Corps' trusty field medic. Thanks to him, many of the team members (but most often its extremely injury-prone leader) have been brought back from the brink of permanent shutdown numerous times.
After the Lightan Corps form an alliance with the entire Bratty Brigade by the midway point of the series, he becomes Monkey's partner.
Despite his rather clunky design, Mechanic has shown himself to be quite a capable fighter, using his Mechanic Drill and circular saws to aid Gold Lightan in battle.
He has also convincingly impersonated God once.
