Maintenance Mek: Gold Leader

Compact assistance meka developed to increase the overall utilization rates of meka groups, providing aid for underwater projects. They were originally designed to remove junk, vegetation, and other underwater debris in order to prevent these from clogging up the vital parts of other clockwork meka, thereby minimizing failure rates. From another point of view, they are undoubtedly benefiting Fontaine's ecosystem greatly as underwater cleaners.
Compared to other mass-produced models, this special "Gold Leader" assistance meka utilizes a clear gold outer casing along with special control equipment. The project team designed it to fulfill the role of a command relay station in particularly complex underwater environments, receiving and re-transmitting commands from the controller to all other meka within the group, effectively fulfilling the important role of leader.
However, as the whole maintenance meka project stopped functioning, these leader meka lost their reason for existence. Only their highly recognizable clear golden casing gives them value in the eyes of the anglers who collect them.
