Top Ten Undertale Characters You Would Feel Guilty Killing

Undertale is an amazing game, and one of its amazing qualities is its cast of characters. You also have the option to spare them all somehow. These are the ones I'd have trouble NOT sparing. I'm not counting Napstablook because you can't actually kill him.
The Top Ten
1 Papyrus Papyrus is a character from the 2015 game Undertale, made by Toby Fox. He is the Younger brother of Sans the skeleton, royal guard in training, and a sentry in the town of Snowdin. Opposite to his brother, papyrus is active, loud, and full of himself; but in an endearing way. Papyrus means to become a full-fledged member of the guard by capturing a human to please his superior. A lover of puzzles and spaghetti, Papyrus provides much of the games comic relief and is a key character in the plot of the game.

He still believes in you, even when you mercilessly decapitate him. Think about this, would you like to be mercilessly decapitated? No? That's what I thought. This is why I can never to genocide. I didn't spare him in pacifist, and I saw what happened. I cried for an hour. He is the key of the game. You decapitate him, sans is coming for you.

Papyrus is my favorite character in the game, so that in itself makes him a bit difficult to hurt. He also believes that, even in a Genocide Run, you can change and become a better person. It shouldn't be a big surprise that he and Toriel topped the list, because most of the fanbase seems to agree with me on that.

Not only is he adorable and the main comic relief of the game, he starts out egotistical and remains so, but you can see why. When you kill him in a genocide though... It always gives me the shivers. He still believes that you can do better, you can change, even while you're killing everyone he's ever known.
Sadder when you put it into words.

I don't know if it's been stated before, but YOU CAN'T KILL PAPYRUS ON ACSIDENT. ALWAYS ON PURPOSE. I abandoned my Genocide run because I had a ton of guilt killing Goat mom, and didn't want to feel it 10 times worse when killing this little cinnamon roll.

2 Toriel Toriel is a goat like monster who is the secondary major character in Toby Fox's 2016 RPG, Undertale. She saves the protagonist from Flowey and guides them through the Ruins, of which she is the self-proclaimed caretaker. She is the ex-wife of Asgore, the mother of Asriel Dreemurr, the adoptive mother... read more

Toriel is there with you right from the beginning, and saying goodbye to her is one of the most heart-wrenching moments in the game. Heck, her battle theme is called "Heartache"! I've seen Let's Play gamers kill her and instantly regret it. I teared up the first time I had the goodbye with her AND when I got to her fight on Genocide.

When you kill toriel she still loves you when I killed her I cried.She wants you to be good. She uses kind words Ben when you tried to leave fighter her and she still loves you. *silence*...That's Just sad!

3 Undyne Undyne is a main character in Toby Fox's 2015 RPG, Undertale. She is the heroic fishlike captain of the Royal Guard, who takes it upon herself to protect the monsters of the Underground. Her name is derived from the word "Undine", and is a pun on the word "Undying". Her most loved monsters are her mentor, King Asgore, her best friend, Papyrus, and her love interest, Alphys.

Her death in all 3 modes is gut-wrenching. In Pacifist, you constantly take away her regenerating health, and in Genocide, you've just killed the only person strong enough to stand a chance against you at that point. Think about that, k?

I just saw her Neutral fight. Her death was heartbreaking to watch as she screams that she won't die. It's a lot worse than Genocide.

4 Sans Sans or Sans the Skeleton is a character in the 2015 RPG Undertale created by Toby Fox. He is a lazy, pun-loving skeleton who is a supporting protagonist in the "pacifist" and "neutral" routes of Undertale, and a heroic antagonist/final boss of the "genocide" route. He is known for his incredibly difficult ...read more.

After killing him, he says the saddest dialogue in every timeline: "Papyrus, what are you doing here? " Or something like that. Point is, I literally cried after the whole genocide run once I killed sans. That changed my life to see his normally happy personality break, showing his depressed, angry side. I no longer am the person I was after that fight, and I never want to be. It was truly sad.

Sans is-SPOILER ALERT- the final boss of a Genocide route. His death is pretty sad, but what gets him so high on the list is that you've also got the guilt of killing all other enemies before him. His fight is awesome, but it's also guilt-inducing.

Sans is a really hard boss to beat, so if you're battling Sans or almost about to battle Sans, as Sans would say, you're going to have a bad time.

Although some people are glad to finally be finished with him after an average of 50 deaths

5 Mettaton Mettaton is a character in the popular 2015 RPG game, Undertale. He is a robot with a soul built by Dr. Alphys, and is the sole television star of the underground. Mettaton is a popular character in the fanbase. His notable features include his legs, and his catchphrase "OH YESSSS!"

So what do you love the most about Mettaton? For me, I'd have to ask: is "everything" an option? This guy's hilarious! AND he wants to save humanity from Asgore! Why would you WANT to kill him?
(to be honest though, his Genocide boss is pitiful)

His death scene is tragic plus it makes alphys feel awful. As an added bonus I have a crush on mettaton. (I turned bi for him lol)

He brings life to the Underground. He's their biggest star. They depend on him. And you left them empty.

Mettaton Ex is the second form of Mettaton When you kill the other form of Mettaton She is a dancer.

6 Temmie Temmie is minor character from the 2015 game Undertale made by Toby Fox. Made in the likeness of her artist, Temmie Chang, in appearance and character. Both a character and a species of monster, temmies are defined by their mix of cat and dog features, as well as their broken English. Their hidden village ...read more.

I'm not even going to explain this one. WHO DOESN'T LIKE TEMMIE!

TEMMIE! in the genocide route this is one of the characters I absolutely can not kill

I will kill her any day,she is my least favorite character in the game

Just a lil' bean wanting some food!

7 Asgore Asgore Dreemurr is a boss monster and the king of the monsters in the 2015 RPG Undertale made by Toby Fox. Asgore is the portrayed main antagonist who plans to acquire seven human souls and use their power to break the barrier that seals the monsters underground . Aspects of his character are hinted at throughout the players journey and his fate at the end of the game is determined by the choices the player has made.

But still, HE IS A DEMON. And he actually is. Look at him when you start the fight. HE DESTROYS THE MERCY BUTTON WITH THE DEVILS WEAPON OF CHOICE. LIKE, PEOPLE! But then again, his death scene is extremely sad. He begs you to take his soul. So sad.

He's not exactly the most liked character in the fanbase, but Asgore had a kind personality, and was only doing what he thought he had to do for his kingdom.

All of his death scenes are so sad...

8 The Greater Dog

It wouldn't seem like much at first, but you basically kill a puppy by doing this.

I can never do genocide because of this. WHY THE DOGS TOBY WHY

9 Muffet Muffet is a character from the game Undertale. She appears in a region called Hotland, selling pastries to raise money to rent a heated limo to help the spider clan from the Ruins (who are also raising a bake sale) reunite with the one in Hotland because the spiders can't cross Snowdin.

It almost made me cry when I killed her and the spider came and gave her a flower! ;_;

The part that really got me was when the spider put a flower at the spot where shs was killed. Very sad.

Mostly on here for how sad her death scene is.

Just a mother trying to reunite her family

10 Lesser Dog Lesser Dog is a character from Undertale. He is part of the Snowdin Canine Unit, and is famous for his long neck.

The sounds that he makes when you hit him should be enough.

He's just a cute little puppy wearing armour!

The Contenders
11 Asriel Dreemurr Asriel Dreemurr is a character from the 2015 game Undertale. He was created by Toby Fox.

Asriel is the child of King Asgore Dreemurr and Queen Toriel, but he seemingly passed away prior to the game's events. His backstory is only focused on in the True Pacifist Route, which means the player does not kill a single character. As a young child, he was a close friend of Chara, a human child who... read more

Cause he was A flower then turns into a mega goat

You can't kill asriel dreemurr

12 Flowey Flowey is a flower in the RPG Undertale. He is the first character you meet, and also your best friend.
13 Monster Kid

When you hit and kill him he not only whispers he doesn't want to die but he is crying at the same time!

If you're doing genocide he's scared of you at this point

Just a lil' bean trying to emulate their hero!

14 Napstablook Napstablook is a secondary character from Toby Fox's 2016 RPG, Undertale. He is the cousin of Mettaton, who left him in order to become famous. Due to this, poor Blooky has crippling depression.

They literally can't die. Ghosts are kinda incorporeal and stuff...

15 Alphys Alphys is an adorably dorky, lab-coat-wearing, bespectacled, yellow-skinned lizard scientist who resides in her lab in Hotland in the critically acclaimed cult classic RPG known as Undertale, wherein she partakes in the daily act of watching insane amounts of anime and having a vast majority of the game's plot-related spoilers attached to her. Plot twists aside, however, she is also well known for creating the fabulous entertainment robot Mettaton, as well as having a massive crush on a young fish woman named Undyne, thus creating one of the most beloved lesbian couples in fiction.

Poor girl kills herself.

16 Burgerpants Burgerpants is a vendor in the 2015 RPG video game Undertale, who sells various kinds of fast food working in MTT Resort, such as a hamburger dubbed "Glamburger", ice cream dubbed "Starfait", and even a steak in the shape of Mettaton's, his employer, face.

Can't kill him. I wouldn't even kill him if I had to chance.

19 and already ruined his life

17 Amalgamates Amalgamates are a group of characters in the video game "Undertale." They are created through experiments combining different creatures and objects, resulting in bizarre and unsettling forms. The Amalgamates are a reflection of the game's themes of compassion and the consequences of scientific manipulation. Their presence adds a haunting atmosphere to the game's underground world.
18 Frisk
19 Shyren

Just... Sad. She could be your singing buddy, but noo!

20 Froggit
21 Aaron

I ship temmie x aaron

22 Chara 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. Their name can be changed by the player and will be assumed as the player character, until the Pacifist Route when Asriel asks for the player's name, which is Frisk. In the genocidal route (achieved by killing as many monsters as you can without sparing), they appear by the end to destroy the world, which happens regardless of the player's choice or intervention. Due to this, most people see them as a villain.
