I vote for Yoda, he has more experience in combat since he's old. And he's powerful yet small! But Darth Vader is cool...and young! Not that old. But he's also strong 'cause of the Dark Force is with him! Is that right? Anyway, Yoda of the waaa-----y!
Vader would have lost to Young Yoda but if they had fought around the time of Episode 4 than yoda would have died cuz too old to do all his crazy flipping stuff.
Vader, "Yoda, I am yo' second cousin" Yoda, "Vader, the force is strong within you" Vader "What da hek, I got no force, I have the darkside" Yoda "So be it" Yoda then kicks Vader's azz and to top it off, he takes Vader's 'saber and spits on it, denouncing the name of Vader Yoda wins all the way.
Yoda would win cus supposdly he was one of the strongest jedi other than vadar but vadar uses his emotions to govern him which makes him weaker. Also have you seen yoda fight in the second one he kicks...yea you know.
Well, this match will be evenly matched. The great Yoda Jedi Master versus the Chosen one, Darth Vader. Yoda would defeat him technique but Yoda would be obliterated by speed attacks and stamina. Overall, they might both killed
