Who in their right mind would want to go up against Darth Vader? This is the guy who allowed Mace Windu to be killed, slaughtered the poor defenseless Jedi Younglings, cut off his son's hand, murdered his mentor, tortured his daughter and was an absentee father. No one, right? Wrong! We have found six who have the gonads to stand up to him. Warning: beware of strong language.
Darth Vader Vs. Buzz Lightyear
Buzz Lightyear is a a Space Ranger working for the Star Command from planet Morph. He is dedicated to the cause, armed with various weaponry of his space suit, travels either via jet pack or with his space vessel. Perhaps one of the things that have pit him against the Dark Lord Of The Sith is the fact that Vader serves the Emperor, and Buzz' sworn enemy is Morph's Emperor Zurg. In essence, the emperor of his enemy is his enemy... whatever the hell that means.
Darth Vader Vs. Batman
Batman wanted to kill Superman until he realized that their mommies shared the same first name, and since then, they've been the best of friends. So he's certainly not going to sit back and do nothing when his buddy has been captured by Darth Vader and held prisoner on the Death Star, depowered by a red sunlamp (which raises a question that no one has probably ever asked: can a Kryptonian tan while under a red sunlamp?).
Darth Vader Vs. Gandalf
This wizard is a member of the Istari Order, and the man who organized and led the Fellowship Of The Ring. He was willing to take on the necromancer, AKA Sauron. All of that makes Gandalf The Grey/The White one of the biggest badasses of Middle of Earth. Will that be enough to take down Vader?
Darth Vader Vs. Adolf Hitler
If there is anyone's ass that the entire galaxy — from Empire sympathizers to Rebel Alliance supporters — wants to see Darth Vader kick, it's undoubtedly this putz. And just to prove his versatility, Vader does so in an epic rap session. Go, Darth; go, Darth; go!
Darth Vader Vs. Lord Voldemort
He, too, started off as a nice guy corrupted by a desire for power. Led down the path to true evil, Tom Riddle ultimately became he-who-must-not-be-named, but he-who-we-don't-fear-naming, Voldemort, the dark lord of the Harry Potter universe. On the surface you would think that Volde and Vader would have more in common than not, and should be sharing beers while plotting the downfall of the universe.
Darth Vader Vs. Ted
He owes his entire existence to a bit of magic, as he was brought to life when his owner, John Bennett, made a wish. Since then, this teddy bear has lived life under his own terms, refusing to take crap from anyone. You think this force-using, lightsaber-wielding douche is going to be any different?
