Took forever, but I'm finally done. Here's a flawless/perfect/no-hit Sans battle, everyone. The dialogue is emphasized and Sans' monologue is edited in at the beginning for your convenience.

    The fact that no hit sans is litreally just two people missing all there attacks for seven minutes never gets old
  • @bobbysriracha
    I like how sans is the only one who realizes he can just use his strongest attack first and he can actually dodge attacks like a player could
  • @kll439
    This is 14 minutes of nobody hitting each other
  • @thechazzler8934
    The saddest thing is hearing him die of camera, asking his brother if he wants anything
  • "Flawless" is definitely a better term than "No-Damage", consider that you take inevitable damage at the end.
  • @luiso8201
    “papyrus, do you want anything?” :(
  • Sans would spend all eternity taking his turn than die and let all reality be destroyed. He doesn't give himself credit, he's the most noble person in the underground
  • This has to be scary for Sans! A human has kill almost every monster in the underground and you are the last hope... And you can't land a single hit on them.
  • can we just appreciate that Sans had about 5 minutes to just rest and do nothing, then continue the battle with part of his stamina, but instead he chats with the player?
  • I think the saddest part about this fight is that sans knows he can't win and constantly talks about it with you. Like he says, it doesn't matter if he wins because it'll get reset over and over until he doesn't. He knows this and still tries his best to stop you

    "Sorry, Old lady. This is why I never make promises." I know, Sans. You tried to promising to Toriel that you wouldn't kill a single human. But the human already killed her anyways. No, not only her. Everyone else.

    “Never fight a man who’s got nothing to lose”
  • @axelf9947
    why did it take me so long to realize that the “old lady” line was referring to his promise to toriel. for the longest time i just assumed he was calling frisk an old lady. why am i stupid
  • Everyone knows sans can take the first turn but did you know papyrus could do the same? he uses his first turn to spare you during the genocide
  • @Ray-cr9wg
    Sans is a character that never lets his emotions get ahead of him. He isn't expressive like Papyrus, and he never gives a straight answer when it comes to his feelings. Except right here at 8:46. That was a moment of pure, unbridled rage. The only time in the entire game that he fully drops the facade of a laid-back goofball you see in the Pacifist route. You can feel how much he hates you, and how badly he wants you dead, even with no dialogue. Truly a powerful moment, incredible that Toby Fox came up with this.
  • @accuratememin
    It's always funny to me how in 5:23 Sans casually admits to lying about wanting to be your friend, to the point where he instantly drops the act and says "welp. it was worth a shot."
  • @yourmother4930
    I like the fact that sans is the weakest enemy but has the hardest fight of all
  • I’m so glad I never did this fight myself. Seeing Sans like this truly breaks my heart. This game is so well written, like I’m still amazed so many years later.
  • @Electric0eye
    I know this is old news now, but it will never cease to bring me joy how meta the Sans fight manages to be while keeping you fully invested. It really feels like Sans, and hell the game itself is fighting back, against you .
  • @Grumania
    when he asks if papyrus wants anything it makes me feel bad for killing him in the genocide run
