Top 10 Saddest Undertale Deaths

I was surprised to see this wasn't a list already, so I figured I'd take action.

The Top Ten

1 Papyrus (Genocide Route)

You know what's worse? If you do spare him, he reveals that he was scared. This goes to show you that Papyrus is not a playful kid. He's a skeleton with an understanding and life as deep as Sans, but he prefers to be cheerful and kind. He knows that he's gonna die, but does a last ditch attempt to save himself and the rest of the underground. Now, it's up to you, you dirty genocidal monster.

Papyrus is my favorite character not only in undertale but in gaming history. And this moment show how deep his character really is.

If there's anybody nice enough to befriend a genocidal maniac and get them on the right path, it's Papyrus. He offers nothing but friendship and guidance to the protagonist and even will refrain from fighting him. You can spare him immediately, but killing him will result in him letting you know he still sees a shred of a good person within you. Even if you halt the route later, killing Papyrus will cause both Undyne and Sans to despise you(more than usual in Undyne's case) - Garythesnail

2 Undyne (Neutral Route)

She's the True Heroine of the underground, with an undying determination

Not funny toby

Great character and very emotional death

I killed Undyne on my first run, convinced that I had too. I never felt more like a total turd killing a character in a video game. I love you, Undyne.

3 Sans (Genocide Route)

Oml this death just ripped my heart-- I MEAN SOUL out of me and tore in pieces. His dialogue to Papyrus is just..

Someone get me some tissues...

This has to be my #1, #2 being Undyne (either route) and #3 for Papyrus (Genocide). Sans is overrated, I know, you find him everywhere you type Undertale, but honestly, Genocide deaths have to be heart-wrenching.

Back to Sans...
When you actually BEAT him, you are just like, "OML YES" but deep inside, there is a "glimmer of a good person" (-Sans) part of you that feels BAD. The one guy who can just not STAND being there seeing DUST of his FAMILY just blowing everywhere. Like, honestly. He is bad to the BONE, killing you more than vice versa, but holy cow man, his death just wants you to reset and hug him in a Pacifist run, or just for me... Hope not...

But hope it helped a bit... Yes, Undyne's deaths and quotes... "I won't die" and "This world will live on" (-Undyne in Neutral or Genocide routes)... are #1... ...more

I straight up CRIED for about 10 minutes after seeing his death. I even, in my head, roleplayed it as just ketchup...but the feels of sadness!

Sans is pretty overrated, but his death was still pretty sad. " you want anything? " - Garythesnail

Sans: heh, didja really think you would be able *slash sound* 9999999 Sans:......... heh guess that's it, huh? heh... just... don't say I didn't warn you. welp. I'm going to grillby's. papyrus, do you want anything?

Read it again, this time pretend to be Sans. What he is thinking right about now. He wanted to protect his own brother, but he couldn't. So now, he fights you, and you KILL HIM. After all his warnings, you get no more. He is dead, and you can't do anything about it. And that last line: welp. I'm going to grillby's. papyrus, do you want anything?

That's it. Sans is gone. EVERYONE is gone. No mercy. Nothing. When you battle Sans, he gives you a bad time, and if you wanted to kill him, your basically SOUL-less. Ok no puns. This is serious.

4 Toriel (All Routes)

This one is absolutely the saddest death to me

That look on her face.
This is why you only play the True Pacifist Route. - Martin_Canine

Nooo Toriel

5 Alphys (Certain Neutral Routes)

It's just really sad to have her let you kill her because she felt guilty...just sad

6 Undyne (Genocide Route)

"This world will live on..."

7 Asriel Dreemurr (True Pacifist)

The fight ending is pretty sad but...
he doesn’t die he just turns back into Flowey

The True Pacifist route is by far the most enjoyable way to play Undertale. You free all the monsters and give them their happy ending-that is, except for Asriel, who's doomed to be trapped in the body of a flower for what seems to be forever. As much as fans hope, there doesn't seem to be a lot of hope for poor Asriel. - Garythesnail

8 Asgore (Neutral Routes)

By killing Flowey, then going back to Asgore to fight again, you can as usual spare him or kill him. Sparing him is the right thing to do(even though Flowey kills him anyway), but if you spare him after following the pattern I mentioned, he will give you his own soul, thus ending his life. In any route except True Pacifist, Asgore is tragically killed and thus causes devastation in the underground. - Garythesnail

9 Flowey (Genocide Route)

Maybe the genocidal weed deserves to be killed, but at the end of Genocide he realizes he's Asriel and begs you not to kill him. Spoiler alert: you have no choice, and must kill him. In what may be the most brutal hits in the game. - Garythesnail

10 The Dogs (Any Route You Kill Them In)

I hate killing Lesser Dog in Genocide. It breaks my heart.

Killing dogs is messed up. - Garythesnail

The Contenders

11 Mettaton (All Routes)
12 Muffet's Death (Neutral/Genocide Route)

Not very sad, but if you kill Muffet then a spider will crawl onto the spot where she died and leave a rose. It's kind of sad, really.

13 Disbelief Papyrus (Genocide route in Disbelief) Disbelief Papyrus (Genocide route in Disbelief)

He only wanted to protect his brother... He still gave you another chance after all that...if my sis got harmed I�'d be mad to the bone. But THIS. THIS. That is brutal.

14 Mad Dummy (Genocide)

It was so happy that it finally got to feel alive... and then you just take that right away from it! Now that is just cruel...
Also I just wanna say that this so deserves to be ABOVE a FAN-MADE character, not below.

15 So Sorry (Pacifist)
16 Toriel (Any Route)
17 Asgore (Pascifist)
18 Flowey (Neutral)

No, I'm not talking about Photoshop/Omega Flowey, I'm talking about right after you beat him, right after he turns into his regular flower form, and when you kill him instead of sparing him when you get the chance. Even though he wanted to die, and makes that face when he says "I knew you had it in you," it's still pretty sad if you think about it.
