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.
Mechno-arms were cybernetic replacements to hands and arms lost in a variety of situations, but more often than not by lightsaber blades. After Count Dooku severed the right arm of Anakin Skywalker in the opening battle of the Clone War, a mechno-arm was grafted to what was left.
Vader had four artificial limbs as a result of his injuries on Mustafar and at the hand of Dooku on Geonosis. The apparatus of Vader's mask was designed to support his breathing.
Count Dooku was not sad after cutting off Anakin's arm in Episode II: Attack of the Clones (AOTC). He was ready to kill Anakin, and only the entrance of Yoda spared the Jedi's life.
Ultimately, Anakin's yellow eyes serve as a visual representation of his descent to evil, a cue for audiences to pick up on while watching the film. They show Anakin is far removed from the heroic Jedi he once was, completing his tragic arc in the prequels.
While most Sith embrace their demon-like appearance, some, like Count Dooku, don't have yellow eyes because they are motivated by philosophical and political goals rather than rage and conquest. Count Dooku's betrayal of the Jedi is often justified, as he recognized the hypocrisy and corruption within the system.
Anakin Got His Scar From Dooku's Apprentice, Asajj Ventress
Ventress, one of Dooku's deadliest assassins, seeks to kill Vos for his actions; however, she is unable to get to him. Instead, she settles for a Jedi she can find: Anakin Skywalker.
Vader's suit is unbearably itchy. He also has needles stuck in him all the time. The Dark Lord has claustrophobia due to his suit. The iconic "I am your father" line was initially kept secret, even from the actors.
Could be any number of reasons ranging from faulty surge protection anodes, to Starkiller and Palpatine having vastly different current frequencies and voltages in their force lightening.
However, Vader lost the weapon when he was defeated and crippled, the lightsaber falling from his hand to the ashy shores. Reluctantly leaving his former apprentice to burn in the lava, Kenobi retrieved the lightsaber and took it with him.
in order to lure Skywalker into a confrontation. She ignited an inferno of rage and fury within Anakin. Their blades clashed, and in the midst of the ferocious battle, Ventress left a lasting Mark on Skywalker face.
By Revenge of the Sith, Anakin was considered equal or inferior only to Yoda. Once he became Darth Vader, Anakin had long become superior to Dooku and Mace Windu. He exceeded their power while still living as Anakin Skywalker, and greatly exceeded their power later in life, both in the force and in lightsaber combat.
Although Qui-Gon never felt close with him, Dooku was quite fond of his former pupil, and Jinn's death on Naboo devastated him. The 2012 Legends novel Darth Plagueis showed Dooku's gradual fall to the dark side in detail, and his feelings on the death of Qui-Gon contributed to this fall from grace.
Sidious may have given Dooku the title of Darth Tyranus, but because the Jedi Order knew him as Count Dooku, greatly preferring to not indulge his role as a Sith, they continued to call him by that name.
Count Dooku was a menacing Sith Lord and central figure in the Clone Wars. Once a Jedi -- trained by Yoda -- he became disillusioned with the Jedi Order and thirsted for greater power.
Before that, the assumption was that any Jedi or Sith could have any blade color, hence the variety of lightsabers among the villains of Star Wars Jedi Knight: Dark Forces II and Legends-era comics giving Jedi like Luke Skywalker and Adi Gallia red-bladed weapons.
A dark side user's eyes would sometimes change color and burn yellow with a fiery red rim when rage and anger seethed inside them. Anakin Skywalker's eyes changed color in this way as he massacred the Executive Separatist Council on the planet Mustafar in 19 BBY, radiating anger and hate.
