- What if Vader and Luke Skywalker time travelled to stop Anakin from helping Palpatine with Order 66?
Here's the official Season 2 of Once Upon a Theory. It has taken many months to finish this one, but we hope you like it!
With the hype of The Mandalorian Season 2 and Bo Katan finally appearaing, I have been thinking of taking Vader and Luke back in time to that period too, just for fun. Or perhaps Vader watching himself fight Ahsoka in Rebels?
What do you think?
The next episode will continue from Episode 1!
Comment your suggestions for what you'd like to see, and maybe they'll happen!

Hey, we hope you enjoyed the episode!
Have a great day!
Master Theory that episode was most impressive. Looking forward to the Maul episode.
Wow that was rlly funny and great can’t wait for the next one!
Can’t wait to watch it already funny 10 seconds in
Since when did mace windu shoot lightning out of his head
Star Wars theory: Hope you guys enjoyed this episode! Have a great day!
Me: OF COURSE I ENJOYED THIS EPISODE AND AM GMOUNG TO HAVE A GREAT DAY BECAUSE OF IT!
The guy doing Anakin deserves mad props. He has the best Hayden Christensen impression I’ve ever heard
Watch Meat Canyon's star wars parodies
Indeed.
thats star wars theory himself haha
@@Gwynbleiddsanity his hayden is hayfen
I was hoping for Matt Lanter type of voice. Especially since Hayden sounds like Matt today.
Would’ve been real awkward if Palpatine told Mace to become his “Dark Apprentice”
“Dark side? Whatchu mean by that?!” 🤨
Instead of Darth Vader Anakin becomes Dark Vader
@@DatFades How about Darth Schacht, or Darth Woede?
@@DatFades In French, this is how Darth Vader is called lol
@Gmail com there is this legendary power called swearing only the one who wields the name is the one called Samuel l jackson
I just can't get rid of the fact that Vader is still alive without his helmet
He doesn’t need full face coverage
@Jon Valler so that’s why he went from “Eh” to “NOOOOOO!”
@Jon Valler yet in return of the Jedi before he dies, Anakin was able to speak. Explain that
@@BrixTremeGeek retcon I guess
Get over it...it's entertaining....This is the way!
2:12 this part had me dying because it's exactly what Anakin would say in this situation
And the fact is that he insulted himself
@@foxgaming1084that's exactly what I thought too.
@@foxgaming1084and he didn't even realise he was being rude to his future self.
All jokes aside, that's a really good Hayden Christensen impression
Yeah it was. It sounded like him and acted like him. I loved it

@@darienschnucker7354 he should make a star wars movie
It's funny because mace windu would never do that as he trained himself in the dark side of the force being one of the only Jedi to while sticking to the light side, understanding after killing palpatine that it needed to be while keeping his emotions in check and staying to the light
Palpatine can control and posses people who kill him. Same with mace.
@@ollielast5077 true and he was faking being weak so if palpatine realised he was gonna lose mace would die and Luke, Anakin and Vader would have to fight him or? I dunno for sure tho
@@laurkanwalton5766 lucas confirmed mace windu was winning
@@randomrazr after the fight got going. Dont forget sidious had windu at saber point early on but didnt finish him. He also had a second lightsaber, so he was not unarmed. Also, he did not use the Force like he did with Yoda, otherwise Windu would have been crushed.
@@kevinthunder3375 according to lucas himself, windu was winning.
one great thing about this animation is, it shows vader's blue light sided eyes. Interesting attention to detail as vader died a jedi and not a sith
Vader saying "Oh, all of a sudden you care about the Jedi Way" is priceless
Like he killed so many ppl xd
lol
Yeah since when the fuck did he care about the Jedi way never.
Perfect like number.
@@andrewcabral963 I think he was just saying anything at that point to convince Mace to spare Sidious.
Plus I guess he assumed that even he didn't follow the code, at least the Jedi's second in command would.
No one:
Not a soul in the entire galaxy:
Mace Windu: *bald force lightning*
Now Dead Force Lightning
Okay baldy, have it your way.
i bet Sam would want that
Thought your pfp was anakin for a seccond
Lol
I’m still not getting over the fact that Mace Windu emitted lightning from his head😂
Windu's evil laugh was hilarious, loved this great job.
To be honest, Windu as a jedi is light in the name only. He's the most hypocritical among them, going dark won't be a great change.
Anakin: "to save the only father I ever wanted"
That is when I realized that they are going back to try and save Qui-Gon Jinn.
I hope they do.

So that he's Qui-Gon Jinn instead of Qui-Gone Jinn.

Dr. Vader Brown: “I did it, I reached 1.21 Midi-chlorians!!!!”
69... nice
It’s over 9000!!!
"so guys, we did it"
Cringe
Hey doc...what the hell is a Midichlorian??
Not so sure about the Mace turning evil thing, I thought his whole thing was he can use the dark side of the force and not be tempted using Vapaad. He's like one of the only jedi that can do that, so I find the ending really hard to believe but it's all in good fun so I'm just gonna try to not take it seriously.
No Jedi is immune to corruption. Mace killed using rage. Many Jedis who gave in to rage while fighting a Sith becomes a Sith themselves. Any Jedi who does not do things the Jedi way becomes a Sith. The way how Mace kills was he was fighting a Sith using his rage. Don't forget that Palpatine feeds on negative emotions. If Mace kills without showing mercy, that is hot Palpatine get his own way. Due to Papatine's negative influence, once turning dark, it is hard to resist that power. Anyone who thinks they can temporarily use dark powers ended up stuck committing to that dark power. Killing a defenseless opponent already counts as a sin. Committing 1 sin can turn any Jedi dark.
Don't forget that even Dooku used to be a Jedi but became a Sith. Sith Lords do have a background of being a Jedi once.
@@hp2546 How was Mace killing Palpatine done in rage? At no point was he angry during the fight. He tried to kill him because it was really and truly the right thing to do
@@hp2546 I mean, seems like Obi-Wan "killed" Darth Maul out of rage
@@hp2546
Palpatine wasn’t defenseless or surrendering and it was selfless reasons to kill him. “It’s not the Jedi way” comes from the unreliable narrator Anakin who has a stake in keeping him alive to chase the way to keep his loved ones from dying
2:30 If your past self hits your future child is it really considered child abuse
LMFAO
It's not child abuse it's SELF DEFENSE
“Mom... I had this awful dream... I was being chased by wampas”

Not really sure how I feel about time travel in star wars. There was a force ability(in the EU) that you could see the past precisely how it haooened.
@@kyle5434 ooh
@@ggt47 yes there was
I have argued for years that Anakin stopping Mace Windu actually saved Windu from turning to the dark side. Cutting Windu's hand did not turn him, Palpatine made him think it did. Anakin only turned when he pledged himself to Palpatine.
Yes! So in a way, Anakin did give up his sanity in order to prevent Mace from going insane. So Palpatine went like oh well! Mace is dead, therefore, to replace him, I will have Anakin as my puppet and make big plans for him to be a Sith.
@@hp2546 Anakin was a much more powerful Force wielder than anyone else at the time. And much younger.
Well you always have a choice. But no he would have killed Palpatine for selfless reasons. He wasn’t surrendering and literally did have control of the courts and senate he’s just going slither away another way. Killing a Sith Lord doesn’t auto make you Sith. It’s not that simple
@@vintifada7115 but that still was not the Jedi way. Technically he was unarmed, and should've been arrested, and held for trial.
Brought before the Senate as a traitor and exposed as the Sith Lord who played both sides of the Clone Wars wreaking havoc in the galaxy and costing the lives of billions.
If Windu had remained calm and hadn't given in to his anger and taken the swing at Palpatine and instead simply said "MASTER Skywalker, help me take this 'PRISONER' into custody, and do not believe anything he says from this point forward." Things would've been different.
@@chrisstetsko5020
“Brought before the senate”
You mean the corrupt senate? You mean the one he refers to when he says “I am the senate” that senate?
He’s not giving into his anger you see that bc you see Sam Jackson like that. He literally did try to take him into custody and palpatine attacked
I loved those ship animations, it actually felt 3d to me
If I'm not wrong, Windu's form of fighting makes him able to use the dark side without falling into it completely.
That's why he is so powerful
I don't think it lets him use the dark side but rather the dark side of others against them selves. You'd have to look up his version of form seven.
@@Treisiess it’s confirmed that he also harnesses the dark side in tandem with the light side to a certain degree, making him considerably stronger.

True Name Video
had to re-watch it so well done
I love this episode but I would like to see more like see this episode continue
Mace’s entire ideology was balancing light and dark forces and using his anger for the light. If ANYONE was going to get corrupted like that it wasn’t going to be him. He devoted his entire life to controlling himself
But what if he broke the balance and tipped too far to the dark?
Yeah, I enjoyed this video, but feels like Mace was corrupted way too easily. For Anakin it made sense because it was built up over time with all of the bad stuff happening to him. With Mace it was kinda like....."Killed the Emperor. Welp, time to be evil I guess" *shoulder shrug*.
Yeah... That Luke wasn't very Luke, that vader wasn't very Vader, and that Mace wasn't very Mace... But it was funny.
Y'all really acting like this is serious when it's very clearly comedy. Like, really?
Mace had been devoted to the light and used dark and light side abilities. He had been fighting a war for how long? While knowing the dark side of the force is growing and clouding the vision. Then he finds a break and thinks he found the dark lord. Takes 3 top masters with him only to see those 3 cut down before him. His brothers in the light to a person with such dominance over the force. Mace has never fought someone like the emperor or someone with the emotional weight. If it was his feelings that helped him bet the emperor then those feelings should have increased to help combat the emperors combat skills. Lots of different trauma occurring at once seems like a good recipe for someone snapping even under normal situations.

Thanks for the likes, peeps! This is the most I’ve ever gotten!
Im gonna be honest i dont think Anakin ever regrets killing the Jedi. His only regret was losing Padme
Yeah he didnt care
I think, in the end, he regrets certain things. Likely the incident with the younglings, probably thinking he killed Ahsoka for a time (When they reunite as Vader, for a short time, she alone is enough to lessen the influence of the dark side), Padme. Obi Wan, maybe. Considering how his ghost appears at Obi Wans side. I think he would regret more that he stayed a part of the order rather than leave.
I lowkey agree
There is a book about Vader mere weeks after he was rebuilt in his suit. It goes through his regrets and mindset during the early days of the Empire. Interesting read, but yes he does regret killing the Jedi, but he only doubles down on his decision, and just believes he had no choice, he was backed into a corner and that they betrayed HIM. Very large complex of “it’s everyone else’s fault, not mine.” Also, Vader states he regretted the perfectionist side of himself he had put up when he was a Jedi and felt resentful towards the other Jedi whenever he deviated from this image. As he continues purging Jedi as a new Sith Lord, Palpatine just plays into this and tells him to let the resentment build and give him power, and so when he kills Jedi as Vader he’s just a huge rage machine.
I think he regrets a little more than that, but to be honest I would say he doesn't regret the jedi as whole (just the specific ones he was close to).
In the end I can't blame him, the Jedi as a whole were a dogmatic group that held together a corrupt system (being corrupted themselves in the process). He was ultimately right that they needed to go (although his methodology could use a little work)
