R2M3 M.A.O. is a walker-styled mecha (Titan) appeared in game Battle of Titans. It is a medium-class Titan capable of mounting three medium weapons simultaneously.
Though likely being a translation error, its full name Mechanized Assault Orgasm has led to speculations that the mech is actually a cyborg. With that being said, only use the tag cyborg if depicted as one.
It has a special skinned variant known as the M.A.O. Cyclops. The paid skin had an infamous bug that halves its own defense abilities.
