Kappadokkios

The Kappadokkios is Kaleidos Green's mech, a Kyklops Root unit. It is able to interface directly with the pilot's nervous system, allowing them to mirror their movements exactly. Green's Kappadokkios wields a mech-scale machine gun in one hand and a beam saber in the other, and to some degree resembles the EVA Unit 01 from Neon Genesis Evangelion.

In GS01 – Torn Pages, Green's Kappadokkios has its saber-wielding hand removed by Zoya Gabbro using the Mimic's vice grip to break its wrist off. In GS04 – Ignition, it's revealed that this caused lingering harm to Green's own wrist.
