Backstory:

Anakin Skywalker was a legendary Force-sensitive human male who was a Jedi Knight of the Galactic Republic and the prophesied Chosen One of the Jedi Order, destined to bring balance to the Force. Also known as "Ani" during his childhood, Skywalker earned the moniker "Hero With No Fear" from his accomplishments in the Clone Wars. His alter ego, Darth Vader, the Dark Lord of the Sith, was created when Skywalker turned to the dark side of the Force, pledging his allegiance to the Sith Lord Darth Sidious at the end of the Republic Era.

A vergence in the Force, Anakin Skywalker was born on the desert planet of Tatooine in the Outer Rim Territories in 41 BBY. He was the son of Shmi Skywalker, a slave who conceived a child without a father. His blood contained over twenty-thousand midi-chlorians, surpassing Grand Master Yoda and all other Jedi in the galaxy. Qui-Gon Jinn, the Jedi Master who discovered Skywalker during the Invasion of Naboo in 32 BBY, theorized that Skywalker was conceived by the midi-chlorians. Following the Battle of Naboo, the Jedi High Council admitted Anakin Skywalker into the Order as the Padawan of Jedi Knight Obi-Wan Kenobi despite feeling that he was too old and emotional to adhere to the Jedi Code. Skywalker remained a Padawan through the beginning of the Clone Wars, instigated by events set in motion by Count Dooku. Although Jedi doctrine prohibited personal relationships, Anakin Skywalker had a secret wife, Senator Padmé Amidala of Naboo. During the early days of the Clone Wars, Skywalker served as a Jedi General in the Grand Army of the Republic, commanding the clone troopers of the elite 501st Legion against the Confederacy of Independent Systems. After receiving his knighthood, Skywalker oversaw the Jedi training of his own apprentice, Ahsoka Tano. By 19 BBY, when Tano walked away from the Jedi Order, Skywalker began to struggle with feelings of failure towards his apprentice and the Order itself.

Following the death of Count Dooku during the Battle of Coruscant, Anakin Skywalker's faith in the Jedi was further shaken when he was put on the Jedi Council without the rank of master. He also learned that Supreme Chancellor Sheev Palpatine was Darth Sidious, the elusive Dark Lord of the Sith who orchestrated the war in order to take over the galaxy. Manipulated into believing that the Jedi had failed him and coupled with his fear of losing Amidala in childbirth, Skywalker betrayed and turned against the Jedi Order, believing Sidious had the knowledge to cheat death. Consumed by the persona of Darth Vader, the fallen Jedi Knight marched his legion on the Jedi Temple of Coruscant where they executed its inhabitants, including Jedi younglings, as part of Order 66 and the Great Jedi Purge. Vader was then sent to Mustafar to exterminate the Separatist Council at the behest of his Sith Master, who became the self-proclaimed Galactic Emperor. Vader subsequently sustained severe injuries in his duel with Kenobi, and was rebuilt as an armored cyborg while his wife died of a broken heart, though not before giving birth to the twins Luke Skywalker and Princess Leia Organa who were hidden from their father and the Emperor as the Galactic Empire rose to power.

When We See Him:

Immediately after his surgery, the Emperor took Vader to a balcony overlooking the old Jedi Temple. There, he and Vader watched as Mas Amedda directed a ceremonial burning of the lightsabers of all the Jedi who had been killed in the Temple. As they listened to Amedda's speech, the Emperor asked if his apprentice knew how or why Sith lightsaber blades were red in color. Vader replied that he did not, as the Temple's information on the subject had been "incomplete." The Emperor laughed and contemptuously mused that the Jedi had been uncomfortable with the information and had buried it as a result. He then explained that kyber crystals felt pain just like any living being, and could be made to bleed after a fashion by pouring rage, pain, and hate into them. He asked Vader if he understood, to which Vader replied that he did, stating that he could have given him any of the burning Jedi lightsabers to corrupt, even Yoda's. But he had not, as Vader realized that the crystal of a Sith's lightsaber should be taken directly from a Jedi by that Sith.
