Top 10 Best Undertale Quotes

Undertale is one of those rare games that's packed with heart, humor, and memorable lines that stick with you long after you've put down the controller.

From the game's quirky characters to its unexpected plot twists, every bit of dialogue seems carefully crafted to make you think, laugh, or even question your choices. Whether it's a funny one-liner from Sans, a heartfelt lesson from Toriel, or a deeply philosophical moment with Flowey, each quote in Undertale offers a glimpse into the story's unique charm.

The Top Ten

  1. "It's a beautiful day outside. Birds are singing, flowers are blooming. On days like this...kids like you...should be burning in hell." - Sans

    Sans is my favorite character in Undertale. I think some people dislike this quote because it makes Sans' personality seem inconsistent. However, I appreciate how this quote is delivered when you think you have fully understood Sans' character.

    Then, when you kill everyone, he seeks to avenge his friends and brother. He cannot simply stand by and let you continue, even if he knows it's impossible for him to defeat you since you can always just come back and fight again. He is aware that if he dies, everything ends. Yet, he still fights. That's true determination.

    Since around summer (August or July, it doesn't matter), I've been learning more about the fandom, and Sans has become a character I love more than anyone else. His puns are funny, he has cool attacks, a cool brother, and even showed me what determination really means. To not give up. To not let your guard down. To not let anything stand in your way.

    When I hear Sans say that genocide quote, it really warms my heart. He's the best character.

  2. "OHHHHHHHH, YESSSSSSSS!" - Mettaton

    I hesitated between this and the Undyne piling on the smooches thing. Mettaton wins in the end, just because he was given an actual voice for that glorious quote. And because of legs.

    Sans is my favorite character, but you can't spoil him! I love Mettaton so yeah. YEAH!

    An incredibly deep message about our society's obsession with physical appearances.

  3. "We are officially screwed every which way from Sunday with whipped cream and a Sans-shaped cherry on top, aren't we?" - Sans

    This is actually from one of the best-worst fanfictions of all time. Giantess Toriel X Asriel: Motherly F-ery. Need I say more?

    I've never seen this in-game, and I'm not even sure if this is a quote, but I voted for this anyway.

    I want to have a sundae like this now. Thank you, Sans.

  4. "I'm Undyne and I'm piling on the smooches!" - Alphys

    Had me wheezing. Alphys x Undyne till the end of time.

    This is me. Why, I don't know, it's just me.

    I can't believe Alphys said that!

  5. "Now your sanity and mine can die together!" - Undyne

    I don't think this was a quote, but it is relatable!

    Sorry, Undyne. Mine's already dead.

    Alphys vs. Undyne was just the best.

  6. "I should have killed you when I had the chance." - Alphys

    This quote is from the Neutral Alphys ending, where you kill everyone except one person in Hotland. That person can be Muffet, one of the guards, or just a random Pyrope, Tsunderplane, or Vulkin.

    Anyway, in this ending, Alphys is in charge now and wishes things were the way they used to be, before your murderous rampage.

    Such an impactful quote, especially once you know Alphys as a character. It doesn't sound anything like something she would say at all until these circumstances.

    This is a quote by Alphys in the Neutral Route Ending (Alphys Ending). I don't like Alphys haters, but I can prove to you that this is a quote by her. Go to the Undertale wiki neutral route. Anyways, it's not so bad, not so good a quote.

  7. "I can't go to hell. I'm already out of vacation days." - Burgerpants

    I literally use this every time someone tells me to "shut the hell up." Yes, Asian people… I put my hands together and raise them up in the air as if to say, "Please, continue."

    And they ask, "How about the hell part?" Then I say, "Sorry, I can't go to hell. I'm already out of vacation days." And I make them cry with laughter.

    Oh god. This is one of the most badass things anyone has ever said.

    I'm just 18 and I already wasted my life on Undertale.

  8. "In this world, it's kill or be killed." - Flowey

    Flowey is AMAZING! Such a great backstory and character traits. So many people dress as him for Halloween because villains are the funniest characters to play. He's my favorite!

    The reason Flowey says this is because when he was supposed to kill the humans and get the souls, he didn't hurt anyone. In return, he got killed.

    Flowey is the best character in Undertale.

    Sans is a close second though...

    Ironically, they are the ones who remember your runs in Undertale.

  9. "You! Will! Never! Spare me!" - Undyne

    Guys, this is a quote if you continually spare her after she turns your soul red.

    This is a quote. Play the game before you hate on it.

    It is a quote and it's awesome. It's almost as much Undyne as it can be.

  10. "Prove to me that you are strong enough to survive." - Toriel

    Probably a teacher when you ask them to go to the washroom during class.

    Best game character with the best tutorial explanations.

    I love how Toriel was speaking truthfully here.

    11. The Newcomers
  11. ?

    "Don't kill and don't be killed, alright?" - Asriel Dreemurr

    It shows that Asriel is actually a nice and loving person that has been turned dark by his fate.

    Ok, Asriel. Don't worry, you'll find a way out of this. You're immortal, so you'll find a way to die eventually.

    Asriel is one of my favourite characters. *Regular Asriel!*

  12. ?

    "Take care of yourself, kid. 'Cause someone really cares about you." - Sans

    I love this quote so much because it reminds me that no matter what, I can get through this. It also pushes all of my depression to the back of my mind, at least for a second or two.

    Don't forget that someone cares about you too! We, the Fandom, will take care of you!

    Please don't make Toriel cry. It will break my weak heart. This is why I did pacifist.

    13. The Contenders

  13. "Our family is bigger than ever. Now that my wife is fused with sixteen other people." - Snowdrake's Father

  14. "Mew Mew Kissy Cutie 2 is neither kissy nor cutie. It's trash!" - Alphys

    Just like people on the Internet, I can't keep track of how many people complain about things they dislike this way.

    This quote is me when I talk about Sonic Boom. There's no Sonic nor Boom, it's trash!

    Basically the same thing as people hating on the Undertale fandom.

  15. "I like to just lie on the floor and feel like garbage." - Napstablook

    This is legit me. Once, we were doing something in my school, and my friend requested us to put T for Trash.

    Napstablook is the best! Plus, he suffers from crippling depression. Lying down with him was one of the best moments of my life! Ah, those beautiful stars...

  16. "Welcome to my special hell." - Lemon Bread

  17. "Who does Alphys have a crush on?" - Mettaton

  18. "You laugh, and keep laughing. It's so funny, you can't stop. Tears roll down your face. What? You didn't do that?" - Narrator

  19. "How many times have I killed you now? We'll start from twelve." - Sans

    I love how Sans counts how many times he kills you, just to be a d-bag.

  20. "Laboratory, Jewish slaughterhouse; it is all in your MIND!" - Gaster

  21. "LEAVE IT TO LAMMYYY- I mean, ALPHYYYYSSSS!" - Alphys

  22. "Despite everything, it's still you." - Chara

    This is hands down one of the best quotes in the entire game. I didn't realize it when I first played a few years ago, but looking back at it now means a great deal to me. It really shows that no matter what happens to you or what kind of changes you go through, you are still you, and nobody can take that from you.

    Me at the beginning of 2020: It's you!

    Me at the end of 2020: Despite everything, it's still you.

    Thank you, Chara. *Hearing this fills you with Kindness* (Sorry, my soul type is Kindness)

  23. "Get dunked on!" - Sans

    Yeah, man, dunk that dirty brother killer in the basket. Party for Sans... Yeah!

    This is why you don't try to spare when you have murdered a whole civilization.

    OMG! One of the best quotes! One favorite way of saying it: "Get dunked on, you monomaniac!" Sans GlitchTale Season One, Episode 1

  24. "Nyeh heh heh heh!" - Papyrus

    This is going to be my 8th-grade quote. I made up my mind. Ain't no changing it now!

    I wonder what this laugh would sound like in real life.

    *Sniff sniff* Beautiful. We love you, Paps.

  25. "Hoi! I'm Temmie!" - Temmie

  26. "You're gonna have a bad time." - Sans

    People probably don't like this quote because Sans follows up on that bad time. Personally, I love it because I had fun with the fight and never got mad or frustrated. Sans was doing the right thing trying to stop the genocidal player.

    I'm sorry I halfway did a Genocide route, Sans! I gave up halfway because killing Papyrus was the most painful thing I have ever done. I'm never starting a Genocide run ever again.

    Yeah, that's right! That's what I'm talking about!

  27. "You never gained any LOVE, but you gained love." - Sans

    Love holds everyone together. It creates peace and a strong connection with people you meet. Sans understands this as he does with many other things. Good quote!

    I was really moved by this, and unfortunately, I have never been able to kill anything in any game since hearing this.

    I used to be confused by this quote. I feel stupid for not remembering Flowey at the start.
