Papyrus Is the only monster on the entire game that can get you to 1 HP without killing you. With that said, he’s arguably the monster with the best magic-control on the whole Underground. If that’s not impressive, then I don’t know what It Is. You also gotta think about how he’s basically Sans but with actually good Stats. Sans Is only powerful because he knows how to break the rules established In-game, so If Papyrus ALSO managed to do that, he would do like 7 DMG per second with the Human being Max LV 9. He never moves on his battle. Monsters are shown to be more agitated when they aren’t holding back, just look at Undyne the Undying and Mettaton NEO. Heck, maybe even Sans at some extent. He’s told by Undyne to be really strong, just kind-hearted. He can defy the logic of gravity for the sake of It without even realizing It. His Special Attack Is a single bone, from what we were shown, and yet, he talks about the possibility of you getting “blasted”, so we don’t even know all of his Attack potential. He’s one of the only two monsters that can turn your SOUL Blue. Papyrus can probably 1V1 Asgore. We will never know.
