Through save editing you can give your character synthetic eyes, genitals and oil fluids.
You can make your skin color one of twenty metallic colors with pickmentation. Maybe latex skin type and Black Latex perk? It's the only type that isn't natural.
There's also cybernetic implants, but the only one with an outward description is the Combat Tail.
As far as equipment, the only real choices are accessories like the Salamander/Bimboleum Defense Systems, the Aim Assisting Eye Pieces, the Jet Pack, the Cybernetic Exoskeleton and any of the drones. Maybe pursue the Engineer class.
