Anakin would have likely been killed by the clone troopers, along with the other Jedi. However, perhaps he would have escaped. He would have taken the pregnant Padme with him. He would have needed to get as far away from the eventual Empire as possible, so perhaps they would have gone with Yoda to Dagobah?
Sadly the Clone Wars would have still happened, but Padmé would have also survived, giving birth to Luke and Leia who would have probably been inducted into the Jedi Order. As for what would have happened between the two, with their marriage and all, that's a bit tricky.
In the original story, Palpatine executes Order 66 AFTER Anakin had already turned to the Dark Side. Meaning Windu was dead. Theoretically, had Anakin not turned to the Dark Side and had not chopped off Windu's hands, then Palpatine could have died, and Order 66 would not have happened at all.
A longtime Star Wars theory suggests that Anakin Skywalker was always destined to become Darth Vader, but the franchise has debunked this idea.
Yoda didn't specifically know how this would go down, or to what degree Anakin would cause it to happen, but he was playing a much longer game by Revenge of the Sith, and that's at least, in part, explained by Yoda's Force connection with Qui-Gon's spirit.
R2-D2 was present when Padmé gave birth to Leia and Luke, so he knew Luke was Anakin's son – but what he didn't know was that Anakin became Darth Vader. In addition to that, Anakin's fall was surely a painful event in R2-D2's life, one that he definitely wouldn't like to remember or even talk about.
One of the main reasons why Yoda would've won against Anakin is simply because he was far better trained than him. Yoda could see the moves his opponents were going to make before they made them; therefore, battling against Anakin would've put him at a far heavier advantage.
The Chosen One was revealed to be Anakin Skywalker, who conceived by the Force itself via the mystical one-celled organisms called midi-chlorians completely without outside influence.
Although the decision to turn to the Dark Side was Anakin's alone, the choice did not come from thin air. His natural prone to impulsivity and emotion without the support systems he needed in place made it easier for Anakin to stumble down a path of darkness.
So, which competitor claimed the top spot for the most powerful Jedi of all time? Drumroll please... Move aside, Anakin Skywalker. Master Yoda has risen above all others to claim the top spot as the most powerful Jedi of all time and the true chosen one according to IGN's audience.
Without Order 66, Palpatine would definitely lose. If Order 66 happened but not for some of the most powerful Jedi and the more battle-hardened and experienced Clones, Palpatine still loses even though many Jedi are killed.
Qui-Gon Jinn is seen by many as the best of the Star Wars prequel era's Jedi, and there is evidence that he could have even stopped Anakin Skywalker from falling to the dark side of the Force.
A young adult novel called Force Collector introduced Naq Med, a former Jedi dedicated to collecting artifacts and knowledge related to the Force. Other confirmed Jedi survivors are Eeth Koth, Zubain Ankonori, and Uvell. Their fates past Order 66 are either dire or unknown.
It's possible Padmé would have still loved Anakin, but despised Darth Vader. "Obi Wan was right..you have changed." So Anakin ceasing to be Darth Vader and becoming Anakin again might have brought back the man that Padmé loved.
Did Anakin regret choking Padme? Oh yeah. He pushed the memories out of his mind for a couple of decades. But after he faced his son, Luke, in Empire Strikes Back, it was all he could think about.
If you remember in Star Wars: Attack of the Clones whilst on Naboo, Anakin Skywalker and Padme are mid-conversation when he tells her that he doesn't care for sand. ” I don't like sand, it's coarse, rough, irritating, and gets everywhere.” Yes, it has been long memed into oblivion at this point.
Yes, he did. He regretted it everyday. But he had no choice. He had gone too far.
Qui-Gon didn't fail to notice the Dark Side boiling up inside of Anakin Skywalker: he believed that darkness was exactly what was needed to bring balance to The Force.
He gave it to Luke Skywalker, who lost it when Darth Vader struck off his son's hand in Cloud City. The lightsaber then became part of Maz Kanata's collection of Jedi curios, where it called to the scavenger Rey.
Having covertly turned Kylo Ren—Anakin's grandson and Luke's nephew—to the dark side, Palpatine orders Ren to find and kill Rey, the last remaining Jedi and Palpatine's paternal granddaughter. Palpatine is ultimately defeated and destroyed by Rey.
If you're talking about Anakin at the end of the Clone Wars and Luke at the end of Return of the Jedi, then Anakin wins hands down. That is Anakin in his prime. His mastery of the Force was exquisite, his lightsaber technique impeccable.
Yoda was reluctant to train Anakin in Episode II because he said Anakin was too old to start training (even though Anakin was still a boy). However, in Episode V, Yoda didn't seem very reluctant to train Luke despite the fact that Luke was a full grown man by that time.
By the time of Episode 3; Anakin is in his prime, and already one of the Jedi Order's most powerful “masters” (although technically still a knight), just behind Obi-Wan, Windu, and Yoda. Maul wouldn't stand a chance.
During Palpatine's reign as Emperor, his apprentice's true identity was kept a secret, leaving only a few Star Wars characters aware Anakin was Darth Vader. Besides Obi-Wan, Master Yoda also knew the truth, as well as Ahsoka Tano, R2-D2 and C-3Po, and even Senator Bail Organa.
