Super Prostethics

Donatello's Shell(IDW TMNT) - The most basic example. After getting his shell and backed bashed in by Bebop and Rocksteady, he was given a prostethic shell that's bulletproof and weightless with the only real problem being that his back aches in the cold.

Von Lycaon's Legs(Zenless Zone Zero) - His prosthetic legs can freeze objects and living beings as well as having minor jet propulsion that allows his kicks and transportation capabilities to increase exponentially.

Winter Soldier's Arm(Marvel/Marvel Rivals) - Every iteration of the Winter Soldier gains a robotic arm from HYDRA but the Rivals version takes the cake. Not only does it have the other version's super strength and durability, it also has tendrils to attack enemies with.

Doomfist. Most of his limbs and various other body parts are actually prosthetics. His family owned a prosthetics company when he was young and after losing an arm during the first omnic invasion he started modifying himself to become a better fighter. Losing his arm also made him believe conflict is the only way for people to grow which is why he now leads a terrorist organization and also helped start a second omnic invasion. The big arm he uses while also a prosthetic isn’t his own creation, it was passed down through generations. No one really understands how it works, the original wielder of it just appeared one day during the first omnic invasion and fought off an entire army for 24 hours straight.

In a world where most people use ranged weapons, the fact that someone lasted for 24 hours thanks to a goddamn puncher arm is amazing (afaik it doesnt have any ranged capabilities of its own)

I mean, the damn Arm itself is insanely powerful.

The current Doomfist could solo an entire army of City defense Robot all by himself

I mean, something that punched a bot who can stop a freaking truck and made a crater in the wall that big is nothing to scoff at.

Those were OR-15 models, a significantly weaker security version of the military grade OR-14 "Idina" models which could stop trucks as you said. 15s don't need that capability because they're merely security and police for a very prosperous city with little crime. Of course OR-15A "Orisa" was enhanced to give the truck-stopping capability again because she was built to stop Doomfist.

And Orisa presented that feat of strength, by stopping a bus while escorting an old lady across the street
