What if Yoda turned to the Dark Side

[hongi]

What would have happened if Yoda turned to the Dark Side after Order 66?

[FaxModem1]

Well, Yoda is a skilled force user and fighter, but he doesn't have any base of power, especially after Order 66. So, maybe king of the Wookies, and that's it.

At what point after Order 66 are we talking about?

[dworkin]

Given that the series is all about Skywalker we really don't know what influence Yoda has except that he's run Space Cop/Monk central for at least 500 years. I'm willing to bet he has a lot of influence, charisma and political skills as a result of that alone. Otherwise he would of been given the 'golden lightsabre' centuries ago.

He knows where failed Jedi go. He knows were the really naughty ones get sent so they don't cause any trouble. He knows an awful lot about various Jedi and their families or where they'ld run. In short, Yoda can gather a lot of apprentices / disciples and so on and doesn't give a shit about the 'Rule of two'.

Now, Vader and Palpy can get ahold of this knowledge by getting access to the Jedi archives but with the info in his little green head Yoda's got a hell of a head start. He also has access to the Skywalker offspring who are chock full of Jedi potentialness.

Yoda's also good news for Palpy, what with Yoda being a clear and present danger and all. It's not good news for the Rebellion since most resistence will form arround Yoda who will twist them from vituous rebels to just another bunch of nasty revolutionaries.

A big question is what Obi-Wan does after his confrontation w Vader since dark Yoda would send Obi wan off to deal with Vader to get rid of the competition.

Lets say after he gets into the Jedi Temple and sees the slaughtered children, he realises that everything he's done and built over the centuries has been for nothing. He realises he's not strong enough to take on Palpatine, so turns to the Dark Side to avenge his failure.

EXETERIOR SHOT: Executor moving beyond the asteroid field.
CUT TO LARGE, BLACK CHAMBER, ENTER VADER
VADER kneels. lights come on.

VADER: What is they bidding, my Master.

A large blurry hologram fills the room. It is the EVIL EMPEROR. He is old and wrinkled, warped by age and his dark powers. His teeth are small and sharp. Most of his features are obscured by a large hood. His sunken eyes gleam with a powerful intellect.

EMPEROR: A disturbance in the Force, there is.
VADER: I have felt it.
EMPEROR: A new enemy, have we. Luke Skywalker.
VADER: Yes, my master.
EMPEROR: Destroy us, he could.
VADER: He's just a boy. Obi-Wan can no longer help him.
EMPEROR: The Force is strog with him. Become a jedi, Skywalker's son must not!
VADER: If he could be turned... he could make a powerful ally.
EMPEROR: Yes, a great asset, he would be. Can it be done?
VADER: He will join us, or die.

HOLOGRAM FADES AWAY. Back in his throne room, the Emperor doffs his hood to massage his long ears.

In Dark Rendezvous, Dooku saw a vision of Yoda as a Sith. According to this vision, Yoda was much more powerful than Dooku or even Palpatine could ever be.

At this moment, Yoda turned, and Dooku gasped. Whether it was the play of the holomonitors, beaming their views of bleak space and distant battles, or some other trick of the light, Yoda's face was deeply hidden in the shadows, and for one terrible instant, he looked exactly like Darth Sidious. Or rather, it was Yoda as he might have been, or could yet become: a Yoda gone rotten, a Yoda whose awesome powers had been utterly unleashed by his connection to the dark side. In a flash Dooku saw how foolish he had been, trying to urge the old Master to the dark side. If Yoda every turned that way, Sidious himself would be annihilated. The universe had yet to comprehend the kind of evil that a Jedi Knight of nearly nine hundred years could wield.

Does anyone has the quote from AOTC novelisation about how Yoda uses the Dark side to surf the future?

It refers to the deleted scene where Windu and Yoda confers, after seeing off Obiwan and before Yoda enters his mediation chamber. I'm not sure whether the movie scene of Yoda vision was described in the novel as being part of the Dark Side vision though.

Is this it?

"Why couldn't we see this attack on the Senator?" Mace pondered, shaking his head. "This should have been no surprise to the wary, and easy for us to predict."
"Masking the future is this disturbance in the Force," Yoda replied. The diminutive Jedi seemed tired.
Mace understood well the source of that weariness. "The prophecy is coming true. The dark side is growing."
"And only those who have turned to the dark side can sense the possibilities of the future," Yoda said. "Only by probing the dark side can we see."

Yup. Thanks!

Do you know whether there is a more definitive quote though?

[Adam Reynolds]

There are two additional quotes that reference Yoda's probing of the Dark Side:
The first gives essentially no additional information, this takes place during the deleted scene where Obi-Wan is getting into his starfighter and talking to Mace.

“Has Master Yoda gained any insight as to whether or not this war will come about?” he asked, somewhat changing the subject, though he felt it was all very connected. Finding the assassin, making peace with the separatists—all of these things would allow him to focus more closely on Anakin’s training and would keep things at a more even keel around the troubled Padawan.
“Probing the Dark Side is a dangerous process,” Mace stated. “I know not when he will choose to begin, but when he does, it is quite possible he will remain in seclusion for days.”

This second quote takes place as Anakin is attacking the Tusken camp. Apparently this is the point at which Yoda probed the Dark Side, allowing him to see Anakin's rage and Qui-Gon's warnings.

Deep in his meditations, peering through the dark side, Master Yoda felt a sudden surge of anger, of outrage beyond control. The diminutive master’s eyes popped open wide at the unexpected strength of that rage.
And then he heard a voice, a familiar voice, crying, “No Anakin! No! Don’t! No!”
It was Qui-Gon. Yoda knew it was Qui-Gon. But Qui-Gon was dead, had become one with the Force! One could not retain consciousness and sense of self in that state; one could not speak from beyond the grave.
But Yoda had heard the ghostly call, and in his deep meditative state, his thoughts focused as precisely as they had ever been, the Jedi Master knew he had not been mistaken.
He wanted to focus on that, then, perhaps to try to follow that call back to the ghostly source, but he could not, overwhelmed again by the surge of rage and pain and…power.
He made a noise and lurched forward, then came out of his trance as his door opened and Mace Windu rushed in.
“What is it?” Mace asked.
“Pain. Suffering. Death! I fear something terrible has happened. Young Skywalker is in pain. Terrible pain.”
He didn’t tell Mace the rest of it, that somehow Anakin’s rush of agony manifesting itself in the Force had somehow tapped into the spirit of the dead Jedi master who had discovered him. Too much was happening here.
That disembodied familiar voice hung profoundly in Yoda’s thoughts. For if it were true, if he had heard what he was sure he had heard…
