Not at the point of Empire, he could've trained Luke and made him more powerful than Sidious (assuming Luke has Anakin-like potential) in the future though.
Mace whooped his ass, and Yoda was able to go toe to toe - so it's not impossible to beat him. Now, Luke might be a bit too old to ever become as powerful as Mace/Yoda/Anakin - but together they might've had a shot. The big problem that those Jedi Masters had in Episode III was that they underestimated the Emperor, if you look at the scene Mace is the only Jedi who steps back when Palpatine draws his saber - the other Jedi stand firm or even move forward and get killed instantly. Mayweather Windu stepped back, analyzed and had him on the ropes.
Vader probably knows the Emperor better than anyone at this point, so he might've had a plan. Shyt he could've just been planning to destroy Coruscant or some shyt, perhaps he never had a duel in mind.
Not sure what we'll see in Episode VII, but in the original follow-ups to 'Jedi' (the novels/comics) Luke was THAT nicca with the forcepowers - I hope we'll see some shyt in Episode VII.
Even in the movies when someone got hit you with Force Lightning you was fukked up Luke took multiple bursts of Sidious lightning and was still able to function almost immediately after. In a very short period of time with
little training from Yoda and Obi Won he was able to give Vader that work with the lightsaber.
Yeah Luke becomes the fukkin man in the books. Like he was pulling star destroyers outta orbit
I copied this list from another site but this is just a peak at his skills.
Shatterpoint- were a complex Force phenomenon, perceivable only by an unknown innate talent or immense focus and concentration on the part of the Force-user. Shatterpoints were akin to fault lines; similar to different pathways of actions. Adept Force-users were able to perceive these faults through the Force, and influence them.
Force Speed The Grand Master was frighteningly proficient in the use of Force speed, often using the Force to increase the speed of his lightsaber strikes, as seen during his duels with Yuuzhan Vong Supreme Overlord Shimrra Jamaane and UnuThul.Luke gave in to the Force and found that time seemed to slow down considerably
Oneness He was described as a maelstrom of luminous Force energy, against which there was no shelter. So calm and focused was he that his actions were not interrupted by any thought. Luke merged with the Force to such a degree that the Jedi Master did not seem to be there, physically or as an individual personality. Luke's control over his lightsaber blade was so great that he was said to might as well have been wielding ten, or twenty lightsabers against the Vong.
Force stealth During the Battle of Kashyyyk, Luke shut his presence down after being fired upon by Jaina to make it seem like he died. Later while Ben was in the Embrace of Pain, Jacen gave Ben back his ability to sense the Force temporarily and Ben felt the life force of his father and realized Luke was shutting himself down to everyone except Ben, something no other Jedi has been able to do
lightning rod he user's body with a low level of electromagnetic radiation. Because of this, if the wielder did not have the skills perfected and attempted to use them during a storm, they would be repeatedly struck by lightning. However, when perfected, they allowed the wielder to disable prosthetics and electric implants, interfere with shock shackles, become a range-boosting antenna for a comlink, among other uses.
Mnemotherapy a Force technique used primarily by the Theran Listeners to visualize the target's memories and eradicate them
Fold space a Force power that allowed a Force-user to bend space to instantly transport an object between places
Blood Trail With this technique, the user used their own blood to mark her target and track them through the blood mark using the Force
Force Blast able to unleash blasts of the Force that manifested themselves as yellow torrents of flame
Electric Judgement Electric Judgment, also known as Emerald Lightning
