Cool Cybernetic Parts for Cool Cybernetic People (HELLWALKERS Cybernetics)

Nebula is my favorite Marvel character because she has cybernetic parts but they don't really grant her any cool powers beyond the superhero standard of "fast, strong, tough." She is a cyborg and she is pissed about it and I relate deeply to all of that (Source)

Cybernetics Rules

1. There are no cybernetics that directly improve upon the function of the original organ.
2. Cybernetics that have special abilities do not function as well at the original organ’s task.

If these items are in a shop and no price is listed, assume they cost 300c (30x a day’s rations). This list is broad but not exhaustive.

Cybernetics are assumed to get enough power internally to work. Some special abilities have a daily use limit. The cost of cybernetics is in the loss of the original organ’s function, not in electricity requirements, so I’m handwaving the latter.

Once you’ve made an organ cybernetic, it takes an hour to swap out different parts. Cybernetics do not take up any inventory space when attached, but take up one if they’re just being carried.

Custom paint jobs and other cosmetic stuff are free, but you can’t cover up the fact that you have cybernetic parts. The function of most cybernetics is not immediately obvious, though, and they’re common enough that they’ll only arouse partial suspicion over concealed weaponry.

I have not seen this movie but I have heard that it is good and that Furiosa is good rep so that's cool (Source)

Arm Alternates
These function as poorly as regular hands—they can hold things but not wield weapons or shields in combat.

Concealed Weapon/Tool Arm - concealed until use - sword, pistol, blowtorch
Heavy Weapon Arm - laser cannon, flamethrower, grenade launcher - 1/day - function is obvious
Magnetic Shield - concealed until use - throwable, returns
Sticky Arm - sticks strongly to surfaces
Telescoping Arm - 10 feet extra reach
Web Shooter Arm - fire temporary sticky ropes
Taser Arm - whole arm can be electrified, dealing damage as dagger
Secret Compartment - +1 inventory slots - items must fit
Extra Tentacle Arm - doesn’t replace existing limbs - can’t wield weapons - no special abilities - can support your weight for moving with 2+ other tentacle arms but cannot dash

Leg Alternates
With these, you can walk/combat jog at full speed but cannot dash. These assume you replace both legs; if you replace just one, they’re half price (150c), but depending on the ability they might have half or no effect.

Calf Rockets - 1 min flight - 1/day
Sticky Feet - sticks strongly to surfaces
Frog Legs - 30’ standing leap
Long Fall Legs - no fall damage
Shin Knives - kicking deals damage as dagger
Telescoping Legs - height advantage at will
Tireless Legs - No exhaustion from rushing overland travel
Hand Foot - can hold things - can’t wield weapons
Secret Compartment - +1 inventory slots - items must fit
Extra Tentacle Leg - see Extra Tentacle Arm

Eye Alternates
None of these can see in the visible spectrum of light. I don’t do penalties for lacking depth perception, but if you must you can apply -2 to ranged attacks.

Low-Frequency EM Eye - radio, infrared - heat and communications
High-Frequency EM Eye - UV, x-ray, gamma - magic, lasers, radioactivity
Sonar Eye - blindsight - 20’ range
CCTV Eye - transmits to handheld receiver - stores short recordings - easily removable
Holographic Projector Eye - 2’-side cube
Overclocked Holographic Projector Eye - 20’ cube - 1/day, lasts 30 min
Laser Eye - damage as dagger - 15’ range

Ear Alternates
None of these can hear normally. I don’t do penalties for lacking directional hearing and I don’t have any suggestions.

Remote Mic Ear - transmits to you - stores short recordings - can’t hear very far
Sensor Suite Ear - velocimeter, altimeter, level (slopes), barometer (weather)
Smoke Grenade Ear - 15’ radius smoke cloud - 1/day

Nose Alternates
These can’t smell and they ruin the taste of some food. -1 HP healed at meals.

Bloodhound Nose - follow scent trails super accurately, given a sample
Air Analysis Nose - identify chemical makeup of air - immune to most airborne poisons and diseases
Rebreather - Hold your breath for 1 hour - breath underwater
People Reader - detect hidden emotions by scent

Mouth Alternates
These ruin the taste of some food (but you can still taste). -1 HP healed at meals.

Steel Fangs - biting deals damage as dagger
Blood Sampler Fangs - non-damaging bite to gather and analyze blood sample
Acid Spit - damage as dagger - 15’ range - corrodes metals somewhat
Prehensile Tongue - 5 ft reach - very weak but still carries small items
Food Analysis Tongue -  identify chemical makeup of ingested material - immune to most ingested poisons and diseases
Hydraulic Jaw - immense bite strength - too slow for bite attack

Voice Alternates
These have unique downsides.

Music Box - imitate musical instruments - cannot speak except in (slant) rhyme
Voice Remixer - imitate noise/speech perfectly - lose own voice - short term memory is 5 min - long term is everything you can hand-write on an index card
Amplifier - voice can be heard for 1 mile - cannot whisper (can still speak normally)
Ventriloquist Voice - voice thrown to a 5’ radius sphere - 60’ range

Skin Alternates
These are fragile; -1 HP. You can choose to augment only a part of your skin.

Digital Canvas Skin - change patterning at will - not great at camouflage
Invisibility Skin - invisibility for your skin, not items - 1/day
Ignition Skin - become fireproof and ignite - doesn’t protect items
Secret Abdominal Compartment - +3 inventory slots - items must fit - technically not skin

This is NOT the look I'm going for--it's too smooth and too perfect (Source)

This is much better--not ultra grimy, but also clearly mechanical and imperfect (by Christopher Cimbaro)
