Re: galen marek runs a Force gauntlet
1. jerec
Marek wins with moderate difficulty. He is undoubtably stronger, but Jerec was an extremely powerful dark Jedi who outranked the likes of Kadann and Sedriss in the Empire and it was heavily implied that he would have been the Emperor's next choice for an apprentice out of his cadre of adepts. And, as I recall, he could also separate Jedi from the Force or disable them with bursts of dark side energy -- Qu Rahn being the precedent.
2. kreia
This depends strongly on whether or not Kreia's Force drain would work on Marek.
3. mace
Marek wins with, perhaps, moderate difficulty. Windu's true threat lay in his ability to wield a lightsaber, not the Force.
4. dooku
Marek wins with moderate to high difficulty. Count Dooku is regarded by various sources to rank among the most powerful Jedi Masters ever, and is "an even greater" Sith Lord. He's also an extremely accomplished master of telekinesis, though his raw power isn't on par with Marek's.
5. yoda
He loses. He's no match for Yoda's greater strength and command of the Force.
6. Darth Sidious
"...but ultimately, [Marek] was no match for the power of Darth Sidious" -- official databank and Complete Star Wars Encyclopedia. He dies.
7. Darth Bane with or without armor your call
Marek wins. His raw strength is easily as great as anything Bane has done, and TFU's novelization reveals he could have destroyed Kazdan Paratus's Jedi Temple with "one push."
8. Darth Sidious DE
Marek dies quickly.
9. Darth Caedus
His raw strength exceeds Caedus's, but the Sith Lord knows far more techniques and is quite powerful himself. It could go either way.
10. LotF Luke [/B]
Luke wins with, perhaps, moderate difficulty.
