Mechno-arm/Legends

The mechno-arm was the custom-made prosthetic limb constructed for Anakin Skywalker after the loss of his right arm on Geonosis. This prosthetic replacement was far stronger than the original. Anakin often wore a black leather glove over his mechno-arm.

On Geonosis, Anakin's right arm was severed at the elbow by Count Dooku's blade. Anakin survived his encounter with the Sith Lord, and returned to Coruscant to recuperate and oversee the creation of a prosthetic limb. This robotic appendage lacked the synth-flesh applied to later models, and had a skeletal, droid-like appearance. Anakin's new arm connected to the remainder of his limb via a synthennet neural interface; a complicated piece of technology that allowed the cyborg to register feeling in his mechno-arm.

Anakin's metal mechno-arm was an advanced version, featuring golden, electrostatic fingertips that simulated a sense of touch. Data collected by the fingertips was transmitted through sensory impulse lines running down the fingers and into an interface module at the wrist. This module served as the junction between Anakin's robotic hand and living flesh. The arm's servos and sensors were controlled by a power cell near the thumb. The mechno-hand's motorized knuckles provide Anakin with a crushing strength far beyond the Human norm.

During the Clone Wars, many of the Jedi Council believed that Anakin lost some of his Humanity thanks to his prosthetic replacement, and were worried that his decreased midi-chlorian count would have an impact on his future exploits. Anakin, however, was well at ease with his mechno-arm, and tinkered with it as he did his starfighter. At some point, Anakin added strengthened alloy ligaments and armoured shielding to bulk up his spindly robotic arm, giving the appearance of a well-muscled arm to match the rest of his toned body.

Sadly, Anakin lost his mechno-arm after his fall into darkness. At the climax of his epic duel with Obi-Wan Kenobi on Mustafar, Anakin lost both legs and his arm to Kenobi's blade, and was left for dead on a black sand bank. Darth Sidious revived him, however, and set his medical droids to work on the wounded Sith apprentice. Now known as Darth Vader, the Dark Lord was given a new prosthetic arm, even more powerful than the last.
