Suggested by Destroyer Dark Vader has a lot of power within The Force. He can do just about anything he likes with it. Since the power is limited only by your force of will, Vader can just try to force choke Lex right off the bat. It won’t be enough though. In some cases Lex has obtained Superman’s abilities and he merged with Brainiac once. His physical speed is enough where he could snap Vader right off the bat before any attack could go underway. Vader’s durability isn’t high enough to prevent this from happening. Lex Luthor wins.
