This is a high-end model from the "Geios Series" used by guests.
A humanoid general-purpose weapon developed with even greater performance than the Geios-Grood, it's flawless in every way. What's most terrifying about it is that it's a mass-produced machine despite being such a powerful weapon (see below). While it's reserved for commanders in the early stages of the game, regular soldiers also pilot it in the latter stages, attacking in sheer numbers. According to the OG series, it's a heavily modified version of the Geios-Grood, designed for senior officers (human commanders) and equipped with excellent command and control functions. However, like the Geios-Grood, production costs are high and production numbers are low.
Equipped with blades in the hands, two large shoulder turrets, and six wing-shaped thrusters, it's a heavily armored machine, and all share a similar color scheme. In the original series, this wasn't explained, and combat demos were simply still images of the main unit, making its structure unclear. Its reappearance over time, with improved animation, has made its structure and function more clear.
