Going off of robocop, two bionics came to mind.
Implanted Armored Visor: Basically Robocop’s visor, only non-removable. Gives you excellent eye protection, but its harder to sway NPCs since you are dehumanized. Also gives you a bonus if you also a targetting module, which it sort of needs since with or without it you get a vision penalty since the visor isn’t the best.
Implanted Feeding System: Either a negative or a RP thing, makes the player reliant on a specific kind of nutritional slush to eat/drink (which is similar to baby food) which is inserted intto a feed. You are unable to consume food normally, and this also blocks the Enhanced Digestive System (and vice-versa), and perhaps negates most food-related traits.
