This question is somewhat related to this one, but I thought I'd ask it separately:

In Episode II, Obi-Wan goes to Kamino and discovers the clone army. He finds that its creation was ordered by a Jedi named Sifo-Dyas. Mace Windu and Yoda both act a little weird when hearing this news, but the only thing they can say for sure is that the Jedi council did NOT order the creation of a clone army. The character of Sifo-Dyas is never mentioned again.

Who in the world was he? Is there anything in the movie that explains who this guy was? Maybe a deleted scene?

  • I think that the answer is on wikia.com is less important than that the answer is the first Google result for "Sifo-Dyas" (unless that page doesn't satisfactorily answer the question).

    Wow, I never expected this question to touch off so much controversy. :) I'm not offended by the close; I've been active on SE for some time, so I understand the need to prune questions. However, I do think this question is a bit deeper than "general reference". I'm not a huge "Star Wars" fan and I find the larger SW definition of canon bewildering at times. Based solely on the movies, I came across a character that is apparently responsible for a very significant plot point and is then (inexplicably) never mentioned again. That is the crux of my question (which could have been clearer). Feb 29, 2012 at 16:53

At first Sifo-Dyas was just a assumed name that Darth Sidious used to order the clone army. But George Lucas changed his mind about it, so the character was used in a story about the fall of Dooku to the Dark side.

Excerpt from Sifo-Dyas (Legends) article of the Star Wars wiki:


[...] Sifo-Dyas was once a good friend of fellow Jedi Master Dooku, and had the gift of precognition. Sometime before 32 BBY, he foresaw that the Galactic Republic would face a devastating war. To defend the Republic, he secretly commissioned a clone army from the cloners of the planet Kamino.
As a final test of his allegiance to the dark side of the Force, Dooku murdered Sifo-Dyas and took control of the project for himself. It was Sidious' true intention to use Sifo-Dyas only as a dead-end cover for Palpatine's plot to use the clone army.

Behind the scenes :

[...] "Sido-Dyas" was originally only a false identity for Sidious—Obi-Wan claimed never to have heard of him, and Mace Windu confirmed that there was no Jedi by that name.
His backstory was promised by George Lucas to be revealed in Revenge of the Sith, but instead is now explained in the lead-in novel Labyrinth of Evil.

  • Bummer that there is no in-movie explanation...I'm still getting used to the whole Star Wars canon thing. :) Aug 9, 2011 at 15:32

    The original explanation made a lot more sense. The emperor wanted war, so he'd order troops! Now so e person has a precognition? Hence, the whole war wasn't planned in any way?

  • @flq Sideous almost certainly planned out the war ahead of time. The specific details may not have been hammered out early on, though.

There’s an episode in clone wars (The Lost One) that has Obi-Wan and Anakin going to Oba Diah (the Pikes home world) to investigate his death, and there’s a holopic of Sifo-Dyas in that episode. However, in cannon, Count Dooku doesn’t kill Sifo, The Pikes do (but under orders from Darth Tyrannus to do so.

This is all canon SW.

  • "Oba Diah!?" Seriously!? Let me guess, there's a world named "Jebe Diah" there too. You know SW is scraping the bottom of the bucket when they run out of names.

  • That's also the episode where the Jedi finally make the connection that Count Dooku is Darth Tyrannus. I mean they only make that connection because the Pikes call him Tyrannus during the fight, but I digress. It also helps understand the state of mind of the Jedi during RotS - they're freaking out because they know the Sith are behind the entire war somehow, and basically commissioned the army that they're leading.
