Duel on Mustafar

The Duel on Mustafar, also known as the Battle on Mustafar, was a lightsaber duel where Anakin Skywalker, now the recently apprenticed Sith Lord, Darth Vader, fought his former Jedi Master and best friend, Obi-Wan Kenobi, on the planet Mustafar in the Outer Rim. After learning of Skywalker's downfall with Grand Master Yoda at the Jedi Temple, Kenobi arrived on Mustafar, where he attempted to reason with the fallen Jedi, not believing the Sith Master known as Darth Sidious, revealed to be Emperor Palpatine, had taken control of Skywalker's mind fully. However, Vader no longer cared for their friendship, and quickly claimed that Kenobi was his enemy; the pair then ignited their lightsabers and locked blades, fighting through the murder scene in the Klegger Corp Mining Facility, where Vader had recently slaughtered the members of the Separatist Council, the leadership body of the Confederacy of Independent Systems.

The fight progressed on the structures of the massive facility that hovered over the deadly lava of Mustafar. Kenobi and Vader soon found themselves trapped on a structure collection arm connected on the facility when it was separated from the facility by the lava and descended onto a hot stream. Kenobi managed to fall onto a lava skiff that was heading in the opposite direction of the fallen collection arm in the stream. Vader soon followed Kenobi and jumped onto a droid collector where the two continued to fight. The Jedi managed to jump onto a high lava bend slope, and claimed that the duel was over due to his height advantage. The Sith Lord attempted to follow, but in his hubris, Vader failed to block Kenobi's final attack, a powerful maneuver which Kenobi severed Vader's remaining organic limbs, and Vader rolled down to the edge of the lava bend, bringing the duel to an end.

Then, Kenobi—overcome with disgust and remorse over his friend's transformation—cried out that he had believed that the fallen Jedi was the Chosen One and his destiny was to destroy the Sith, but instead he joined them. Unable, but most likely unwilling, to connect with his former best friend, Vader was consumed by the fires of the lava that leaked onto the lava bend; leaving the Sith Lord to die, Kenobi retreated and took his fallen apprentice's lightsaber. Afterwards, Vader's new master, Darth Sidious, found his injured apprentice and took him back to the galactic capital of Coruscant, now known as Imperial Center, to be rebuilt; the suit that Vader donned there was one that the Dark Lord of the Sith would wear for the rest of his life.
