This video concerns Vader being beaten by a non-Force sensitive human.
It happened outside of canon by accident.
Long ago, BEFORE
Phantom Menace, my friends and I played the Star Wars Roleplaying game almost every day in the 1990s. We didn't know or care about the Sith's Rule of Two.
We operated on the assumption that Vader was the Emperor's
best Dark Side wielding minion that Palpatine commands, but not the only one. We figured since the canon states the Empire controlled a
billion worlds at its peak that it seemed reasonable that Palpatine had a least a hundred Dark Jedi or Sith minions.
Anyway I ran on a one-on-one game for a friend. He wanted to play a Dark Side user who defected from Palpatine's service when he grew sympathetic to the Rebel Alliance. Not because he agreed with their ideology, but because Palpatine kind of sort tried to genocide his home planet. He wanted vengeance, and he shared a common enemy with the Rebels.
This was 10+ years before the Battle of Yavin so Vader and Palpatine's other servants were still mopping up the last of the Jedi (we guessed, the prequels weren't out yet), but my friend's Dark Side character was inflicting considerable damage on the Empire. His best strategy so far was to use his Dark Side powers to sneak into space stations and sabotage capital ships in dry dock.
I decided to send Darth Vader after him since I figured a Dark Side user brutally attacking the Empire was far more dangerous to the emperor's plans than a Jedi hiding in a cave. I was not going to have Darth Vader
kill him, that'd be too ganky. I just wanted to force my friend to have his character run away. Then maybe be a little bit less blatant using the Dark Side to tear up the Imperial Fleet. At the time, my friend's character was slumming with space pirates. I figured if Darth Vader started whooping up, the PC, (who was very Dark Side after all) would have not problem letting all his pirate allies die to cover his mistake.
The thing about the West End Star Wars Roleplaying game, is that absurd swings in luck are relatively common. And it just so happened that despite Darth Vader's massive piloting skills, his star fighter king of sort got shot down by nobody space pirates. Because we played a lot of
X-wing and
TIE Fighter we sort of assumed that ejection seats had 99.999% accuracy. So Vader was
technically unharmed.
I didn't feel like changing canon to let Vader die early, so I bent the rules a bit and let Vader use the obscure Force Scream power to telepathically blast a bunch of pirates. This forced them to withdraw. Anyway, the player character tried to explain to his friends that they shot down Darth Vader, but the pirates did not believe him.
That game was full of absurd David versus Goliath moments like that. It goes both way. Every once in a while a lowly storm trooper or Compforce soldier gets on a dice hot streak and utterly humiliates a powerful PC who just mowed down eleven storm troopers without breaking a sweat.
