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)

Yea only reason I never did genocide and the reason I stopped if I did

You know what's even sadder about this?
He thinks you're trying to hug him. - TheCrystalWolf

Papyrus: just dies like i...still..see...a...good person in you...
Me:you filthy MONSTER!
i've gone on the date like 20 times

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.

2 Undyne (Neutral Route)

I'm a huge fan of Undyne and she's definitely my favorite character along with Papyrus. If you decide to kill this hero, she stays determined to live on by thinking of all the people she loves. Her mentor and father figure Asgore, her love interest Alphys, her best friend Papyrus...they're the reason she's fighting, and she refuses to let herself die. As she slowly fades away, she shouts that she can't die because she must protect everyone. Along with the depressing music track that plays with it, it makes it an incredibly sad experience.

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

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.

Great character and very emotional death

3 Sans (Genocide Route)

This should be No.1 all he wanted to do is protect everyone even his poor brother "papyrus do u want anything"

It makes me feel like I am being stabbed in the soul...
Gosh just so frisking sad.

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!

4 Toriel (All Routes)

Even when you kill her, she isn't mad. And then when her soul breaks...

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

Be good, won't you?
M y... c h I l d... - TheCrystalWolf

5 Alphys (Certain Neutral Routes)

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

?, you can't kill her - SaavianyDuco

6 Undyne (Genocide Route)

"This world will live on..."

7 Asriel Dreemurr (True Pacifist)

I cried so hard at the end of the True Pacifist route. I just couldn't bear leaving him behind.

He doesn't die, but he might as well have. No matter how we look at him, there's just no more Asriel in Flowey. - TheCrystalWolf

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

I cried so hard the day I did pacifist run...

8 Asgore (Neutral Routes)

Asgore wanted more than anything to meet Asriel. And then he did, in the worst way possible.

It's sad to see Asgore's life taken from him, just as he experiences a glimmer of hope for the first time in decades. - TheCrystalWolf

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)

Not that sad. Sure, he might do the Asriel face, but he isn't really Asriel. - TheCrystalWolf

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


If you kill them, you are basically killing puppies. :( - MinecraftDoge

The Contenders

11 Mettaton (All Routes)

Mettaton is my favorite character in UT if I ever play it won't do genocide I will spare him beacause he is too innocent 😢

12 Muffet's Death (Neutral/Genocide Route)

Not as sad as Sans, but VERY sad

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 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.

14 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.

15 Papyrus (Neutral)

It's so sad because, if you get his health low enough, Papyrus will spare you. It's impossible to do by accident.

16 Temmie (All Routes)
17 So Sorry (Pacifist)
18 Toriel (Any Route)
19 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.

20 Chara (All Routes) Chara is a character in the game Undertale by Toby "Radiation" Fox who is one of the seven people to fall to the Underground prior to the fall of the player character. Her name can be changed by the player and will be assumed as the player character, until the Pacifist Route when Asriel asks for the more.

We never see Chara's death for ourselves, but look at the impact it had on the rest of the Underground! Asriel died fulfilling their final request, the whole kingdom despaired, Asgore and Toriel broke up, causing Asgore to wage war with humanity, which then led to the deaths of six innocent humans. From what we've seen in the tapes, Chara poisoned themself in an attempt to help free the monsters from the Underground, but the plan went wrong, and their sacrifice was all for naught when it only led to the death of Asriel and the devastation of all the monsters in the Underground.
If this isn't tragic, I don't know what is. - TheCrystalWolf

21 Asgore (Pascifist)
