Anakin Skywalker (who just came back from being Vader) threw Sidious over a power generator.
himself ,his master is Darth sidius
Darth Vader (like Darth Maul, Darth Sidius, etc.)
They are Darth Sidius (Palpatine), Yoda, and Anikain.
It could be Darth Maul or Darth Sidius. The Phantom Menace refers to the working of the Sith Lords within the Inter Galactic Republic. I tend to feel that Darth Sidius was the Phantom Menace. Because the phantom did not let his identity become readily available and gained power by usurping it by devices of deception.
Chancellor Palpatine, also known as Darth Sidius. Or, in case you meant the noun, it remains as Emperor. Emperoress is the female variant.
I can't name them all because that is a hard question my young padawan... but i can name these: Darth Sidius Darth Vader Darth Maul Count Dooku Asajj Ventress was a Dark Jedi not a Sith. Ignore this answer. Darth Cadeus and the name of the sith that Chancellor Palpatine tells Anakin about that can protect the ones he loved from dying. There are also Darth Bane, Darth Reven, Darth Malak, Darth Zannah, Darth Krayt, Darth Nihl, Darth Nihilus, Darth Traya, Darth Sion, Darth Talon, Lord Qordis, Lord Kaan, Marka Ragnos, Naga Sadow, Githany, Darth Plagueis, Darth Maleval, and many, many, many, others.
Presumably at the hands of her apprentice, Darth Cognus.
Lightning by Darth Sidious.
Darth Revan vanished when he was defeated by an Imperial strike team, but it is not known whether he died.
Darth Sidious is a Sith lord and the main villain in the Star Wars movies. A patient and manipulative person, Sidious, under the guise of Senator, and later Chancellor Palpatine orchestrated the transformation of the Galactic Republic into the Galactic Empire. He also played on Anakin Skywalker's fears in order to turn him to the Dark Side and dub him Darth Vader, whom he then order to help wipe out the Jedi. Sidious then established himself as emperor and ruled for some years until Vader killed him to save his son, Luke Skywalker.
