Her gun is strangely much more put-together than she is: a monstrous Abyssal gunturret mounted atop a mouth-and-a-half filled with teeth, jaws, gun barrels, glowing energy, and disturbingly organic-looking mechabare. The hose dangling from the bottom has detached and hangs loose.
While she is quite easily mistaken for Ancient Destroyer Oni, there are some key differences:
Princess looks like she's been through the wringer, as opposed to Oni, who seems quite undamaged.
Princess's Abyssal gun turret looks more completed and properly built than Oni's; the two upper sets of teeth ahve been fixed and set neatly together, while the lower jaw sits in the center between them; the internal parts exposed by the open mouth look more deliberate and less haphazard.
Princess's much longer hair hangs down in the back, while Oni's hair is either shorter or pinned up.
Princess has a longer side-drill.
Princess has a white tasuki on her right shoulder, while Oni does not.
