who can defeat luke if anybody can

IMHO NJO Luke cannot be beaten by any one person alone.

Dude bulls*** man!
I'd love to see anyone try and step to him.
I admit, guys like Revan and people in his time era would put some hurt on him, but.... he's Luke, he's, almost pure force.

NJO Luke could only be beaten y Nihilus in a one on one fight IMO.
But i think that to extremely powerful siths, like Revan and Ragnos, together might have a good chance...

no they couldn't no one could beat NJO luke in a one-to-one fight apart from possibly marka ragnos all the others you listed would probably put up an extremely good fight but wouldn't win, luke is ridiculously powerful

Marka Ragnos, Naga Sadow, Ludo Kressh, Revan, Exar Kun, Tulak Hord, Adjunta Pall could all beat him.

Yes he could.

Exar Kun

and Ajunta Pall could all beat Luke alone.

Revan has less force power.
Plagueis is not that good in lightsaber combat.
Hord has less force power.
Sadow has less force power and is not that good in lightsaber combat
Exar Kun has less force power.
Ajunta Pall basically is a Dark Jedi with a powerful sword.

From that list I only would give Ragnos a chance to beat Luke. NJO Luke with unifying force is just too powerful for anybody else.

Nihilus would own his ass...

Revan possibly
Ragnos would make a great fight probably
Tulak Hord is probably better with a lightsaber so that would be a nice fight
Sadow Probably couldn't do it
Exar Kun has a pretty good chance would be a great fight at the least
Ajunta Pall, don't think so but not sure.
Plagues, no way in hell.

Darth Nihilus is probably the only one. Marka might be able to do it...

All the other powerful Sith would put up a good fight, but no...

Hmm...Nihilus would own everyones ass with his special ability. Or Luke would just snap his fingers and make Nihilus disappear in a black hole.

IMO, Only Lord Revan could beat NJO Luke.

Is this limited to the star wars universe?

What about Darth Nihilus? He could absorb luke's power and the OWN him bigtime

already mentioned, but true.

I very much doubt that...

But except Nihilus its all left up to doubt

Luke isn't as good as you saw he is. I think that Obi-Wan in episode 3 could defeat Luke.

I must admit that I disagree. As to Luke's pure power and the power of the Sith listed above, I must contest several things:

Ajunta Pall couldn't even handle the power of a weapon of his own creation, which doesn't mean that he's weak, but I still think Luke is more powerful.

Revan is also indicated to have fallen prey to the power of Pall's weapon, bringing Revan's power into the same amount of question as that of Pall (again, being corrupted by the sword does not mean one is weak, but it certainly shows that Revan is only human, and besides, I think Luke could avoid the same fate).

Tulak Hord's power level is never mentioned. He relies on hand-to-hand action, it seems, and I don't know how he'd react to a black whole popping up out of nowhere.

Exar Kun, I think, is not as good as Tulak Hord, so I believe Luke could beat him as well. It would be a great fight, though. These all would. I just think Luke would find a way to triumph in the end.

Naga Sadow is incredibly powerful, but I think he's too craven and lacks the natural ability needed to win.

Marka Ragnos is the big ticket here. Him against Luke would be like Cassius Clay versus Rocky Marciano.

Lastly, Nihilus's power is effective, but the fact is that Luke would probably find a way to beat him. His ability would certainly give him the edge, but with all Luke has done, I think that he is clever and powerful enough to win the fight.

Yoda would´ve kicked his butt of and he would get a spanking from the little green jedi master.
"Much to know about the force, you still have"

NJO Luke, I believe, is better than Yoda. But anyways, welcome, Mr. General Bondius, sir.

Drop kick to the face would shut Yoda up. I still am curious where people get their Plagueis info and as for Luke popping up black holes. Yes he could manipulate the dovin basals but not create black holes I don't think.

Luke has just been proven more resourceful than anyone else. One on one fight he may lose to a few people but given time and a second match he would figure something out.
