I'm not sure the policy of VS threads at this particular Star wars forums, but for those who have read the EU, what are some Characters from the different eras that could take Vader from the comics/Original story line? What are their feats of power/your opinion on how they could defeat Darth Vader?
I believe Sidious and Vader to be the two most powerful Sith of all time. I don't think any other Sith have a chance against them.
Well the two most powerful according to Bane's line, I know Sidious is canonically the most powerful of all Sith. But I'm not aware of the same applying to Vader, other than the infamous "80%" of being Palpatine's power.
