Revan

In April 2014, as a result of its acquisition by The Walt Disney Company, Lucasfilm rebranded most of the licensed Star Wars novels, comics, and video games produced since the originating 1977 film Star Wars as Star Wars Legends and declared them non-canon to the franchise.[6][7][8]

Revan is depicted as a former Jedi who, along with their best friend Alek (later Darth Malak), left the Order to lead the fight in the Mandalorian Wars due to the Jedi's inaction. One year after the end of the Mandalorian Wars, Darth Revan and Malak returned to Republic space at the head of a massive invasion fleet. Calling themselves the Sith, they declared war on the Republic. Since their intention was to unite the galaxy under one ruler so they could attack the ancient Sith Empire, they avoided attacking key places such as Coruscant, Onderon, and Dantooine. The Sith won the battle, but as Revan prepared to duel with the Jedi who boarded their flagship, Malak, in the hopes of destroying both Revan and the Jedi, betrayed his Master, ordering the ships under his command to fire on Revan's flagship's bridge. Though Malak believed himself to have been successful in killing Revan, they survived. Revan, severely injured from the turbolaser blasts, was then taken by Bastila Shan and her Jedi strike team to the Jedi Enclave on Dantooine where the Jedi Council members chose to wipe Revan's memory, and imprint them with a false identity that the player creates at the beginning of the game, choosing the character's gender and appearance.

Knights of the Old Republic begins with Revan awaking on a starship under attack. Throughout the game, Revan learns of their forgotten history and assembles a band of followers as they search for "Star Maps" to lead them back to the Star Forge, which Revan used to make their army. Revan eventually encounters Malak, who reveals their former identity as a Sith Lord. Malak later captures Bastila and turns her to the dark side. Her ultimate fate depends on player's choice to follow the light side or the dark side throughout the game. Canonically, Revan remains loyal to the light side, defeats Malak, and destroys the Star Forge. The last scene of the game's canonical ending shows the main characters, including Revan, being honored by the Republic at the site of the temple on Rakata Prime; a picture of later events has emerged from subsequent games and novels.

The sequel Knights of the Old Republic II: The Sith Lords reveals that a year after the defeat of Malak, Revan recalled a threat from their time as a Sith Lord, and left known space to deal with it. Clues to the nature of the threat emerge from in-game dialogue with non-player characters (including Canderous and Kreia); this varies according to the player character's alignment and gender.

Prior to the events of the sequel, Revan bade farewell to the nine comrades who had accompanied them on their quest, knowing that none of them could safely accompany Revan themselves in the places they had to go to; the only NPC with a certain knowledge of where and why Revan left (their navigation droid, T3-M4) won't divulge the information. Also, at the ancient tomb of Ludo Kressh in Korriban, the Jedi Exile fights a silent vision of Darth Revan, in which they appear to wield two lightsabers, one red and one violet. The game lists the color crystal of the lightsaber the player obtains from them as a unique red color. This is Revan's only physical appearance in the entire game. Additionally, the Jedi Exile can speak with several companions and non-player characters within the game to learn more about the history of Revan, and their journey into the Unknown Regions.

Revan appears as the primary focus of Star Wars: The Old Republic: Revan, a tie-in book to Star Wars: The Old Republic that was released by Bioware and EA on December 20, 2011.

Revan re-emerges in Star Wars: The Old Republic after a team of Republic heroes manages to rescue them from the Emperor's Maelstrom Prison with the help of the ghost of the Jedi Exile. It is revealed that Revan was kept alive for centuries as a prisoner by the Emperor to channel Revan's strength in the Force. Revan's link with the Emperor was two-way, however, and they were able to keep the Emperor's darker urges in check, thereby preventing the Emperor from unleashing his full power upon the galaxy before the Republic and Jedi Order had grown enough again to be able to stand a chance against the Sith Empire. Though thankful to the Republic for rescuing them, Revan decides to fight the Emperor on their own terms and takes control of a Rakatan installation called "The Foundry" and engineers a droid army (led by HK-47) programmed to identify and eliminate any target with Sith DNA, which not only included Dark Lords of the Sith but also the majority of citizens of the Empire. Revan's plan is thwarted when a group of Imperials manages to infiltrate the Foundry and destroy the droid army and HK-47 before confronting Revan. After a vicious battle, Revan is defeated but disappears before a killing blow can be delivered.

Revan appears again in the "Legacy of Rakata Prime" flashpoint as the mastermind behind the conspiracy in the "Forged Alliances" plotline. They are the primary antagonist of the fourth digital expansion to The Old Republic, entitled Shadow of Revan, in which they return to destroy the Republic and Empire. They lead a group of followers known as the Order of Revan or "Revanites", into infiltrating both galactic powers and influencing them into annihilating each other. Some Republic and Imperial forces also declare themselves loyal to Revan. Revan then draws the Empire and Republic into a battle with their Revanite ships over the planet Rishi, so that neither the Republic nor the Empire can interfere when they confront the Emperor. However, their plan is thwarted when the player character sends a communication to Republic and Imperial ships informing them of Revan's plan and telling them to cease all fire.

Revan is later cornered on Yavin 4 where they try to raise the Emperor but is confronted and defeated by the player and an alliance of Republic and Imperial characters. After the Emperor makes his presence known and leaves Yavin 4, an apparition of Revan appears and reveals that when they were defeated in the Foundry, only their light side became one with the Force, while their dark side, fueled by hate for the Emperor, survived, setting off the "Forged Alliances" plotline. The two sides of Revan, one Jedi, the other Sith, then reunite, with their now-whole spirit warning the player and his allies that they must undo what they have done, lest otherwise the Emperor will see his evil plans through and everything will be lost.

Darth Bane: Path of Destruction, Revan appears as a holographic avatar for a holocron discovered by Darth Bane.

In celebration of KotOR's 15th anniversary, Electronic Arts added the Jedi Knight variant of Revan to Star Wars: Galaxy of Heroes as a playable character on October 18, 2018.[9] Months later, the Sith version, Darth Revan, was included in the game as the first unlockable Dark Side mythic character, followed by Darth Malak.

Revan was originally slated to appear in the animated series Star Wars: The Clone Wars. In the third-season episode "Ghosts of Mortis," Revan would have appeared as a Sith Lord alongside Darth Bane as advisors to the Son, a dark side embodiment. Revan was cut from the episode in late production since their presence would conflict with Lucas' view of the Force at the time.[10]

The visual dictionary guide for the 2019 film Star Wars: The Rise of Skywalker contains a reference to one of the Sith Eternal's legions being named after Darth Revan.
