ok only you could answer this. We're counting on you. here goes: who would win in a fight, Batman or Darth Vader? They're on Earth but not in Gotham. Batman has all of his standard weapons but so does Vader.
vader is more likely if they met at random, because batman isn’t much compared to a force user. he might have learned the holy art of raising his body temperature to bake eggs on his abs, but vader can choke the life out of him from a half a mile away. like if we’re playing rock, paper, scissors, lightsabers beat kevlar, and force power beats martial arts.
i mean, batman could always use an electric batarang (what 80s band is that) or whatnot and hit vader with it, but i think he’d realize pretty quickly that the suit is life support, and if he hits it he runs the risk of killing the man inside. depending on the desperation of the situation, he may or may not go for that. if he had the time to study the actual suit, he might win, but even then it’s kind of a long shot - vader is like a human lawnmower. he both is human, and also mows through humans, and has none of those pesky morals to hold him back
