Pepper is my flagship female character, but it took me a LONG tome to give her armor rather than have her be a 'Tomb Raider' rip-off.

NSA (Nanite Screen Armoring) is the armoring she wears for combat missions that require the utmost stealth. The actual NS (Nanite Screen) is a thin, transparent material made out of nano-machines that bend light around it, making the object it surrounds completely invisible to the unaided eye. However, it requires an electrical charge to refract light. The silver parts are made up of a Kevlar-type material for protection, and the flexible-tubing makes up the rest, and for final protective layering. Fer tail and muzzle are covered in a grey cloth covered in NS, not Armoring. Even her weapons are covered in NS, meaning you won't see her until you're already dead.
