I was considering how to make her action sequences more interesting, alongside trying to more closely fit a theme of her being a rescue robot, so I'm thinking of giving her a 3d printer in her chest.

I'm planning a scene where the detective character (who is currently looking like our main character right now) gives Unit 9's pilot kid a thumb drive full of gun 3d schematics, and its up to the pilot to figure out how it is used.
