Most Powerful Jedi of All Time

It depends greatly, also, on WHO wields said sides. Did Luke ever manage to create/save life through the light side as Plageius did with the dark side?

Why is this?

As it is stated before, you can't compare different era's. It's like comparing a scientist from ancient greek times to sayyyyy Albert Einstein.... ofcourse Albert is smarter, the human race evolves everyday in small ways.

So with that logic you would believe that Luke is the strongest Jedi, but at the same time Kreia said something in KOTOR 2 while on Korriban that I always remember (I know, she mentions Sith not Jedi but the point remains) "this was the tomb of Tulak Hord, known as the greatest Lightsabre duelists of the Sith Lords. His skill was considered remarkable even in his time, when many true lightsabre masters lived." Exile asks: "are you saying modern jedi are poorly skilled with a lightsabre?" and Kreia replied with "If you were to face an ancient Sith Lord in combat, you would learn that we are as children playing with toys compared to the
prowess of the old Masters."

So this little tid bit of info from the EU makes me think all jedi/sith from KOTOR - Legacy of the Force are weak compared to ancient Jedi/Sith. Ofcourse that is just with lightsabre combat.

However since we do not know much about the Jedi and Sith that came before, if we follow this logic then the masters of the force from TOR era would be a little more powerful than the jedi of the movie era... but my bet is still on Luke as his father was made purely by the force and only contained a slight amount of dilution of none force user DNA... but since Ani never truly reached his potential on that note his SON Luke did or still is reaching his potential.

Far to many ppl put far too much merit in her ramblings.

luke skywalker is BECAUSE...

when he is re building the jedi order he studies ALL aspects of the force... he gets a power that allows him to see how an event would have played out if somthing ells would have happend...

and shaterpoint power is amazing

also he is the chosen one

Vader was the chosen one. He killed the emperor and restored balance to the force. Even tho he was dark side to begin with he ended up coming to in the end and killing emperor. Most powerful though, i'd have to say Sidious.

I got the impression Sidious enginered that, he wanted Anakin to attack Windu.
One moment he is crying weakness, the next he unleashes force lightning whilst grinning and saying something like absolute power.
He had left himself in positions of weakness before, like where Anakin had his lightsabre drawn on him and Sidious feigned being unharmed and at Anakins mercy.
Sidious was not just powerful, he was devious and fooled the jedi order and republic with ease.
