In Episode VI: Return of the Jedi, Emperor Palpatine plots to replace Vader with Luke as his apprentice. That made me wonder, just how powerful was Luke during and up to Return of the Jedi? We know that in the prequels, Anakin was extremely powerful, more than Yoda and Palpatine. Was Luke at that level, after less the a year of training? Or did Palpatine only want Luke because he thought he had no other options?
I believe that Luke had a close (although not equal) potential to Anakin's force power. And although Luke was not as powerful as Vader was at Endor (despite besting him in combat), the Emperor had realized the limitations Vader had with his injuries and felt that Luke could be more powerful then Vader, but not as powerful as Anakin if that makes any sense.
Absolutely not. Luke was a faster learner than even his father, but Luke still could not match the raw potential Anakin possessed as the Chosen One. Still, Luke was more than capable of surpassing the mostly machine Darth Vader. That is why Palpatine was so interested in recruiting Luke. Let's just say that if ROTJ Luke and ROTS Anakin met on the battlefield, ROTJ Luke would put up a fight but ultimately be defeated by his father in most instances. Luke had gone very far in a short time, but he's no Anakin in the original trilogy.
Luke had equal potential ton his father when both were complete and whole. However, Anakin losing all his limbs and becoming more machine than man lowered his potential below Luke who still had most of his limbs.
I don't think Luke was anywhere near the warrior that his father was - he's a quick learner, definitely, but his swordsmanship is very imprecise and clumsy, even in Return of the Jedi, and most of the training he had with the Force was based off of only a few weeks/months he had with Obi-Wan and Yoda. Anakin (and, thus, Vader) had a decade of extensive training with some of the greatest Jedi of the ages and then became the apprentice of the most successful Sith in current history. His cybernetics bog him down but they don't undo this. But where Luke lacks in experience, he makes up for in ways that his father couldn't. His unyielding loyalty to his friends and ideals cost him his hand but it also granted him his humanity. Where Anakin was willing to destroy anything to save those that he loved, Luke was willing to sacrifice his own life (multiple times). Luke's strength is in his character, his ideals, the purity that managed to redeem one of the most ruthless men of the galaxy back into the path of goodness. He didn't beat Darth Vader with his strength; he removed his hand, sure. But he really defeated him when he threw his weapon away and gave himself to his cause. And that is an incredible power of it's own.
Luke during ROTJ is definitely not as powerful as ROTS Anakin//Vader. If they'd duel, Anakin would beat Luke for sure. Luke might be able to put up a good fight but Anakin will eventually beat him. Why? Because Anakin has better training and experience while Luke has a very limited mentorship by Obi Wan and Yoda. Luke at his full potential might be able to beat Anakin, though. Lukers is right Luke did kicked Vader's ass in RoTJ but ultimately it's his heart and love for his father that had defeated Vader. Vader was, in the end, killed by the reborn Anakin Skywalker and it all happened because of Luke, who pulled him back and gace him a chance
No. Anakin was stronger. But the fact Luke chose the light side and resisted the dark side makes him better by default.
Equal or exceeds on potential but far less training so his abilities were not fully discovered this is why he didn't know how to absorb and deflect the force lightening.
luke has more potential then machine vader but not as strong as anakin. it was pretty clear to me anyway that's how george ranked them
Unless Luke can hold the very embodiment of the light and dark side of the force in his hands the way Anakin did on Mortis, equaling a feat only the Father could do then no we have never seen any indication Luke has anywhere the same potential a fully trained Anakin would have had. I guess now that disney has reigns to the franchise we could see mention of it in Ep 8 or 9 but we'll see.
