Guyver III (Guyver 3; Agito Makishima) from anime and manga Bio-Booster Armor Guyver.
Rig is work-in-progress and as of now is only good for some poses.
Additional zip-archive contains .obj and .fbx files, textures, and addons for Blender that may be needed for working with the rig.
FBX file is just the geometry, not rigged and not textured. Only the fibrous part is UV unwrapped.
Update 2022.05.14: New texture for eyes, finalized forearms and lower legs (no more mirrored shape), remodeled thighs, fixed knee topology, minor head tweaks.
