Grandmaster Luke Skywalker vs. Darth Sidious and Darth Bane

Hmm. I'm torn.
 
Palpatine beat Luke in Dark Empire. But that was prior to his ascension to Grand Master. Dark Empire took place 6 years after Episode VI (Dark Empire was in 10 ABY, RotJ was in 4 ABY). Luke was in his prime around the New Jedi Order and Legacy eras (25-40 ABY). In my opinion, Luke would win against Palpatine. He might beat Bane as well.
 
It would be a good fight. Luke could pull it out, though.

" @JediXMan: Why is Luke firing lightning? Can't only Dark force users do that? "

Luke can take either 1 on 1, but if it's both of them 2gether..that may even be more than he can handle. Both were exceptionally strong.....hmm...it's an interesting question...but i guess i'm gunna back Luke.

Hard to say. Darths Sidious and Bane are pretty up there. Combined, I think they would overmatch most incarnations of post-ROTJ Skywalker, but when Luke becomes more advanced in age is when the real questions pop up. I'll give him the nodd, hard-fought 8-9/10.

Dark Empire Sidious vs Grandmaster Luke is an even split really , both have chances to beat one another , tho Palpatine could outsmart Luke by using his Optimism and kindness against him , but if that doesn't happen , I really don't know who would win such a battle .

Darth Bane is Probably weaker then Qui Gon Jinn and The Phantom Menace Darth Maul , he is simply buried under tens of generations and millenium of pure upscaling because of the Rule of the Two , he cannot really add anything in this Fight , it would be like Empire Strikes back Luke attempting to interfere in Revenge of The Sith Yoda vs Revenge of the Sith Palpatine or having Ezra interfere in the battle Of Darth Vader and Ashoka in Star wars Rebels , Bane is a non factor , heck his generations superior Tenebrous and Plagueis are no factors in a battle of this scope , Palpatine would either kill him instantly so he doesn't get in the way or distracts , or he would simply just Die in Crossfire .

Bane dies from the aftershock of their fight.

Luke beats Sidious after a close match.

Bane isn't adding much here.

Grandmaster Luke takes Sheev down after a good fight.

Luke raises his finger, Bane explodes.

Sidious and Luke have a decent-ish fight before Luke wins.

Bane is a complete non-factor and Luke takes Sidious mid diff at most

Luke has nearly lost to a lot less in character due to him always holding himself back.

He can win if he's serious all the fight. But there's a real chance he could lose.

Luke

thats mostly just PIS rho.

@maulsmacker: Except they literally went to the trouble of explaining it IU as a constant thing Luke struggles with. So its not even PIS. Its a character trait.
