This version of the Anakin Skywalker minifigure is based on what Anakin looked like after his duel with Obi-Wan Kenobi on Mustafar, in which his legs were severed and he was left there to burn in the Lava River, although Palpatine rescued him. There are two versions of this minifigure. One shows him with his black Jedi torso and legs, a burned head and no hair. The other shows Anakin with a reddish tone to his skin, a torn Jedi robe and legs, a red lightsaber, and a Darth Vader helmet. This version appears in the 8096 Palpatine's Shuttle. Oddly enough, Lego Star Wars: The Video Game shows a cutscene of Anakin's transformation into Darth Vader, yet Anakin has a full head of hair and does not appear to be burned like this version of Anakin (which is similar to his appearance in the film).
The most recent version of the minifigure appears in Lego Star Wars: The Force Awakens as part of the Prequel Characters DLC. He wields dark Force powers and his red lightsaber.
