Originally posted by DeadpoolXXXI think an argument could be made that a prime OT Vader was at(or very close to) the level of RotS Palpatine... At least where saber skill and general power/TK are concerned. Because per new canon: peak OT Vader > RotS Anakin/Vader(ala "Knightfall"😉 > RotS Anakin(momentarily tapping the dark side) >>> Dooku.
how MUCH stronger though?because tking an opponent from light years away is a huge cry from tking an opponent from a nearby planet.
Thing is, Palpatine spent the decades between the PT and OT hoarding as much knowledge as possible, in order to increase his own power... So by the time of ESB/RotJ, he had become powerful enough to own OT Vader with a few casual finger-flicks(as we saw in the comics.) Moreover, he has also schooled Vader in almost every conceivable way when it comes to overall usage of the Force(in both the comics and novels.)
So yeah, even though canon has gone out of its way to hyper-wank Vader any chance they get(and he IS uber as hell, no doubt), Palpatine is still just on a completely different level.
But if you're looking for an answer like: "OT Palpatine is 'x' times more powerful than OT Vader", then I can't give you an exact figure... SW doesn't work that way. Palpatine might be 20% more powerful, or he might be 500% more powerful... Who knows?
