Yea, I played one of them, but it got really confusing, so then I bought a computer game, but it only works for Windows computers, and I have a Mac...

please, KOTOR is to be discussed in the games section...

I hope my directional advice doesnt offend an admin...

Fav Jedi: cause of the character: Anakin Skywalker from EP II to III (until he becomes Vader)! I will say it again, Hayden is the perfect Anakin!
cause of the power: clearly Yoda, the most powerful Jedi of all times!

Fav Sith: cause of the self confident appearance: DOOKU! If you also read the book in which Yoda and Dookus realtionship is told about, I clearly can see why Dooku is such a cool character!
cause of the power: Darth Bane, period.
cause of the character: Vader!

First i'll agree and disagree:
Luke- although I agree with his placement, I don't think he would have been anymore powerful if he was started at an earlier age. For this reason: Ben and Yoda didn't train him as a "Jedi" so much as a "weapon" against Vader and the Sith. If he'd been raised from an early age, he'd have been instructed in a specific lightsaber style, history, politics, dipomacy, etc etc, and not as much time on becoming the Alliances ultimate weapon against the empire. Plus, Luke was on a time table.
Now, if Luke had been instructed in the same manor for 20 years of his life, he'd be 5x as powerful.

Ben- I think this is a good placement, but not completely accurate. I think Obi-Wan was just as powerful as Yoda during the fall of the Jedi, but not stronger, perfectly even. There were several Jedi in history more powerful than he, the to-come Corran Horn, and JacenSolo/DarthCaedus.

Yoda- Was quick, agile, wise, and force powerful. He didn't need his saber, if he wanted to, he could've took Sidious down with his powers alone, but didn't, becuz i beleive he sensed the future, and saw that Vader's redemption would rely on Palpatine's survival.

Anakin- A generous placement. Anakin was no where near the peak of his potential when he was turned. I beleive if Anakin/Vader wouldn't have lost half of his body to the lavas of Mustafar, he would've became INVINCIBLE. Becuz, when Vader lost his arm and legs, he lost millions of his midichlorians, and his midi-count dropped severely.

Sidious- he was defeated by Windu, and could've been defeated by Yoda, and ofor reasons I've already explained.

My line up would be:

Luke
Obi-Wan/Yoda
Mace Windu
Sidious
(Anakin/Vader)

Then my expanded universe line up:
Luke
Galen Marek(Starkiller)
Corran Horn
Ben Kenobi
Mace Windu
Jaina Solo
Jacen Solo/Darth Caedus
Darth Bane
Sidious
Vader

I am just now coming in so I do not know where yall are haha. This is my list of the most powerful jedi/sith ever. According to abilities, accomplishments, and individual power.

Darth Pheobus
Darth Nuhilus
Mace Windu
The Exile
Darth Traya
Ulic-Qel Droma
Revan
Galen Merick
Darth Plageius
Yoda
Darth Bane
Anakin Skywalker/Darth Vader
Palpatine
Exar Kun
Luke Skywalker
Obi-Wan Kenobi

What do you think?

Yoda, no doubt about it.

"That's not true, that's IMPOSSIBLE."

I beleive that it would be either Darth Nihilus, or Darth Pheobus.

Nihilus was a towering sith lord with incredible strength, intimidation, and power in the force. He had the ability to completely consume the force out of anyone and anything that had it, feeding off of it and growing more powerful, skilled, and hungry everytime. He destroyed entire planets, races, orders, etc with that one power alone. Not to meantion, he had an entire sith fleet at his command. Sion was also allied with him, and they were both hunting and killing off the remaining jedi knights, and were doing a very good job. Not only that, his race, name and origins are completely unkown. According to my understanding, you can only defeat what you understand correct? The Exile however unintentionaly, found a way to live without the force by his wound and at the same time could command it. By having this nearly impossible thing unexplainably happen to him, the exile was able to starve the sith lord to his breaking point, outnumber him and kill him. Were it not for this once in a galactic lifetime occurance with the Exile, Nihilus would have been INVINCIBLE and would have consumed the entire galaxy. nobody could have beaten him. There would not even be a star wars episodes one through six. He was the only being ever in existance (that I know of), to know and master the force power 'Force Consume'.

I would also say Darth Pheobus, because she also had some very unique and nearly impossible abilities. She was the only person ever, sith or jedi in her way, that could transform into any opponent and use their skills as well, which would confuse and highly distract the person she was fighting. On top of that, she was a master of the twin blade lightsaber. with these abilities, she took on groups of nearly anything (exhageration) and would win lol. Last but not least, she founded a cult that revered her as a godess or something to that nature. She and the cult grew so powerful and destructive to the galaxy, they began not only killing off jedi but sith as well! For the first time ever, the entire sith and jedi order had to put away their differences and come together in order to defeat her. I think that is pretty desperate for two factions that want NOTHING to do with eachother. There are more I think could be the best, but I'll start with these two. Any disagreements? And why?

I would go with one of the more ancient sith lords or jedi. My pick would be Revan, because he defeated Ajunta Pall, one of the ancient Sith Lords, on Korriban, not to mention thousands of jedi and sith, as well as millions of Mandalorians. He was the most powerful Sith of his era, and deserved the title of Dark Lord. He knew every force power in the book, had mastery of the lightsaber, and one of the greatest potentials ever seen.

Nihilus can't really be considered having Force Consume as a force power cause he was really a "hole in the force" as Kreia said. He ended up devouring so much that he couldn't devour the exile, and eventually he would have consumed himself, destroying all Jedi and Sith. He was like an exterminator of the force, and since Kreia hated the force, that's probably why she chose him as an apprentice. He was powerful, but couldn't contain his power. He could not stop his hunger and had no control over it, which is why he needed to devour entire worlds to sustain himself.

yes, i havnt read much of the BBN stuff, but i've read stuff on wookiepedia about how powerful the ancient sith lords were. Revan, Nihilus, Bane, Ragnos, and Phoebus to name a few. Can anyone tell me what was so great about them all besides Bane and Ragnos(i know enough about those two anyhow) So the basics of Revans, Nihilus', and Phoebus', er, awesomeness?

Revan was basically great because he had control over both the light and the dark side. He had a great deal of force powers from both sides, which is what made him such a deadly force wielder. He was able to rally a cause against the Mandalorians, and stop the True Sith from arriving from beyond the outer rim by becoming the dark lord of the sith himself. He didn't fall to the dark side, as Kreia said. He willingly joined it in order to keep an eviler sect of Sith from rising to power. They were known as the "True Sith", and we know little more than that a Jedi Exile and Revan went to destroy that empire. Revan began as a jedi, joined the dark side, and returned to the light despite loving a jedi called bastilla.

Nihilus was an intimidating figure at first glance with the white mask and dreadful noise that comes from his mouth. He was a hole in the force, because he discovered a way to kill entire planets which is a power called "Force Consume". However, he couldn't contain the power. In order to stay alive, he had to drain the power from entire planets and force sensitives. When the Jedi Exile confronted him, he couldn't drain the exile's power with force consume. He was killed by the exile.

That's all I know from playing KOTOR 1 and 2.

Nihilus shouldn't be so close to the top because he couldn't control the abilities he discovered. If he didn't use force consume on worlds, he would have died because of an inability to sustain his hunger. I think Revan, because he knew the dark side and light side in great detail and defeated the Mandalorians should be at the top. I consider Revan to be the most powerful force wielder ever. He defeated spirits of ancient dark lords of the sith on Korriban, and gained control of the galaxy.

Thanks mvader.
Yes, Nihilius shouldn't be near the top, becuz like mvader said, he couldn't control the powers he held.
Many, MANY years ABY, Luke discovered much of the Dark Side's powers, such as lightning and many others, as well as a Light Side equal to Sith Lightning, which takes the color of your midichlorians aura, many times the color of your lightsaber. Luke is still, in my opinion, the most powerful being in the SWU. But after what i've been told about Revan, i think Revan should be a close second.
