Let's beat Undertale, and kill EVERYONE 

Therm is gonna hate it when he redoes pacifist and gets to the end of it.

As someone who loved Undertale from day one, it makes my day to see all these years later people experiencing it for the first time. It's so rare now. That silence at the first "but nobody came." was EVERYTHING

the fact he was close to the end of the sans fight ON HIS SECOND TRY is really impressive

One really subtle thing about the Genocide route I noticed is that the “!” before encounters is eventually replaced by a smile.

Undyne melted when you killed her because in that fight she somehow generated determination, her body eventually couldn’t take the strain anymore and melted before turning into dust, the melting also happened to the amalgamates due to the determination in their system and monsters fused together and formed them

here's a fun detail i enjoy. Asriel (as flowey and as himself) consistently greets the player with "howdy!", a habit that you can later infer he picked up from asgore. meanwhile, the first fallen human (default name Chara) says "Greetings", which is _toriel's_ habit

The Toriel reaction was probably the best part here “Let’s start chipping away-oh MY GOD.” 12:34

“You’ll have to erase my memories too” Therm: I’ll gladly kill off Flowey

i dont know why but therm saying 'A LIFE' in response to sans saying 'papyrus, do you want anything?' made me both start cackling and tear up

I made my gf play through the pacifist run and then bought the game for myself for the sole purpose of never tainting that happy safe file. Forever untouched and free.

"After this is all over, I'm going through on my own time and doing everything my own way so everybody gets their happy ending" Oh... yeah. They deserve that happiness.

i love how the literal point of the genocide run is to make you accept that you are the one who did this, but therm just keeps blaming other people

I absolutely love the True Reset, Toby’s final tug on your heartstrings by making the villain of the game beg you to not erase the happy ending you worked so hard to get everyone Yet his speech is said with a feeling of inevitability, he knows that it’s likely that you’ll go back and ruin everything, that anyone who loves the world enough won’t listen Then you get to the menu, and see the True Reset itself, and it’s amazing The usually lively file select screen that’s normally populated with the characters doing fun things, is now completely empty, barren of all the monsters because they’re all gone, they have no reason to stay in this abandoned mountain, but you’re here, even though you shouldn’t be, like them, you should leave this Undertale and head back to the surface, you aren’t meant to be here, and that atmosphere is emphasised by the droning music in the background, it’s slow, horrid, the type of stuff you’d only hear on the genocide route, and it’s fitting because being here, hovering over that true reset button is a form of starting that genocide, first you kill their happy ending and then you kill them (You can actually hear this droning music in the video if you listen closely on the menu screen 1:33) But yeah, amazing work by Toby to make you feel like crap before you’ve even began the geno route

sorry idk why i'm just DYING at the completely unexpected baseball tier-list at the end of the video. what a great way to diffuse the tension after a really emotionally rough run.

32:35 This is the point that Sans talked about. The more you distance yourself, the easier it becomes to hurt others. 'Taking her out.' 'Getting into a rhythm.' 'I did it, this is a big moment'. This is the point where I can hear Therm speak like he is playing a game and this is a challenge that needs to be conquered. Forgetting that you are the villian and the true hero does not stand a chance. The same thing happens when people fight Sans, they get frustrated and only... once the final blow hits do they realize what they've done.

at the end my heart was hurting so bad and then therm just starts GIGGLING at chara's "Greetings."

Fun fact: The I Frames in Undertale are called Mercy Frames. Depending on the fight your Mercy Frames differ. It's the amount of time before you can take damage after being damaged by an attack, and things can influence it. For example the more of an enemy type you spare, the more Mercy Frames you get. The monster is showing you Mercy. Sans gives you no Mercy Frames. He does 1 damage, every frame. Quite literally no Mercy. Also, in Undertale you do damage based on your intent to hurt. That's why boss monsters are almost always instant killed. And why Sans takes 999999 damage. Your character is pissed.

This route literally just destroys your humanity. At the beginning, he was guilty for killing one froggit but by the end you could tell he didn't give a crap anymore

I bet therm had a heart attack when he beat the game in pacifist again after he sold his soul

Therm: “i do not like this” Also therm: “i wonder what monster dust taste like”

If you spare Sans, he doesn't actually spare you. The soul they're referring to at the very end of that route isn't the heart that appears in combats... It's the *player's* soul. In this case, your soul... You being Therm. Sometimes people will react to things they shouldn't know from previous playthroughs, like Toriel guessing your previous answer to the Cinnamon vs Butterscotch question. When you play through this time, you'll likely get a little bit of new dialog or whatever here and there... But probably not enough for a whole new video.

Therm: This is so sad, I'm gonna need therapy after this. Also therm: *FIRST BLOOD!!!!!*

FUNFACT: When it's the talking rock, you only need that one to get thru, you didn't actually have to push the other two.

I played the genocide route twice, and failed twice, I could NEVER do it, the first time was at papyrus, and the second time was at sans, I think the sans getting dunked on was a fitting ending, I always imagined it as Frisk gaining control back, and ending it before it could never be fixed.

For the record I voted for them to stay happy…

I'm gonna be completely honest I cried when I did my first genocide run. I just get way to attached to the characters. It hurts so much then you have to kill them.

41:57 This is extremely funny because Undertale speedrunners use the Burnt Pan, and if you hit all 4 crits (frame perfect inputs, by the way), you will do more damage than a crit with the Real Knife. So your decision to use the Burnt Pan instead of the Real Knife was technically correct lmao

As someone who did a pacifist run and never wanted to do genocide but was always curious, wow. Flowey’s really calling me out there…

I suppose Therm knew, going into this... He was gonna have a bad time.

THANK YOU [[Thermal Energy]] FOR MAKING A [[BIG SHOT]] MOVE, [[You are now eligible for a new]] MY [[Commemorative Ring]], ALL YOU HAVE TO DO IS [[GET OUT WHILE YOU STILL CAN!]]

This route is so sad. I once watched an analysis video on it and it's crazy how Sans dialouge during the 'Judgement' scene reflects what happens when the player goes into genocide.

Thimbs: yes, everyone is good, nobody will suffer and FIGHT won't exi- Thumbs: GET OUTTA HEREE

1:04:27 "I did whole lot more than kill, that was extra credit."

This hurt Therm Edit:in a yoda voice now : Therm was hurt by this he was

As something of a breakfast expert myself, I think that pancakes are a clear winner with French toast close to waffles at 2nd

I was lucky enough to catch these streams, but the streamlined chaos of Therm's reactions and sarcasm is bringing on the laughter needed to watch this emotionally unfulfilling path of death. Thank you for enduring this path for us, Therm. 💖

i clicked on this to give it the view but i am physically unable to watch genocide runs of undertale bc i love the characters too much

1:03:18 Can this please be the one dude I don't kill? Flowey: *Y E S*

most peaceful therm video:

Papyrus’ expressions and attitude make me so sad… I freaking almost cried when he died! I could never do this in a play through…

I love how everyone on their pacifist run prefers butterscotch, but on genocide, they say they prefer cinnamon.

dying sans: "papyrus do you want anything?" therm: "a life" the perfect combination of witty & savage is unmatched 😂

2nd thing: This makes me glad that some people will still play the genocide route so I don’t have to do it myself.

"after this is over - in my own time - I'm going through and I'm beating this game again so everyone has their happy ending" Who's gonna tell him?

Such a masterpiece, was great watching you play through it on stream

"Greetings." "I've seen you killed my family, partner."

In the first 5 minutes I immediately thought "Well, this guy's gonna cry for sure."

32:30 goes with the music so nicely

Flowey called me out for wanting to watch but not want to do it myself.

Undyne is the best character. She had the determination to keep fighting forever. But the monster soul cannot handle it. She was prepared to fight forever but when she lost using everything she had, her body couldn’t handle anymore. She didn’t ever die to death. She died to her own will to live.

i cant believe you moved the mets back to b tier, easily the saddest thing about this video

the thing in the description sounded PAINFUL mate, also was really funny to watch but that wasn't a splash that was a SLAM

I bet froggit’s dust would taste like mustard 13:13

i like that at the end he just started ranking things because he wanted to see if the game would do anything.

I love Therm dying to Sans as soon as he calls himself a 3 of Diamonds

finally had time to watch this! such a great video to have on in the background. i love these longer style videos. your commentary is always fantastic

I like to call this route a clensation of the underground. First time i died over 74 times against undyne the undying and RESET when i had to fight sans This time i only died under 40 times maybe between 24 deaths and i am still fighting against sans

I’ve become a fan incredibly recently and you are one of the funniest content creators I’ve seen! I love watching your vids and find you hilarious :]

“ we gotta avoid the bone zone “ -being left alone with someone I like a lot 👉🏾👈🏾

I appreciate seeing Undertale play throughs. It’s truly a magical game, and is definitely in my top 10 of not at number 1.

Undertales genocide route really helps capture the stages of grief, especially denial as is shown perfectly in this video

Sweet! This was a nice surprise. Was hoping you’d come back to this at some point.

I love how Therm just casually makes a tierlist of baseball after he finishes the game 😂

Glad you made this into a video, almost had to watch the entire stream ha

Yay! We both found Undertale together! It’s 2023 and I just finally looked into the hype that was Sans and such. Not disappointed, and now I’m here watching every Undertale play though. To see someone play this game so recent, it fills you with determination. 🌟

no, YOU destroyed this. YOU chose to press fight. Y O U . did this

Therm doing a baseball team tier list while waiting for the game to continue is my favorite thing Also heck yea O’s and Nat’s in s tier frfr

I can’t believe sans just tries to filibuster you

Absolutely wrecked emotionally every time I see the run, but this vid was great! Also great to see the Buccos in A tier! Let's go Bucs!

Bro tried to sneak in an undertale playthrough in a baseball ranking video

45:37 It'd take 15 hours for train 2 to catch up to train 1.

Next time on Undertale: Soulless Pacifist Route! ... no, I'm not kidding, it's a thing. ... is it worth it? Nah, Pacifist then Geno is better in my opinion for learning more lore in a more fitting order. Actually, a Normal Playthrough is kinda nice in itself, like killing a bunch of stuff and bosses but also sparing and stuff, idk... Undyne Normal Route is the best fight emotionally in the entire game =)

50:04 famous last words.

44:40 Oh, no. Flowey is talking about *YOU.* He's talking to Frisk/the first human, but the player(As in, you) is a separate entity altogether, and that's who he's referring to. A being who wants to see what happens, but is incapable of doing it on their own. This line occurs regardless of if it's being recorded/livestreamed(Undertale can't detect that, after all.), and Toby never really expected Undertale to be a big thing people would stream. He's talking about you, not the live chat. And you don't get to blame us for you playing genocide. As the game itself is trying to tell you: You didn't have to make a poll. You didn't have to respect the results of the poll. At any point, you could have decided to stop. And we couldn't have done anything about it. We never forced you do to this, only encouraged you. You made the choice all on your own, and you don't get to blame us to avoid the pain. *Trying to do so is missing the point of Undertale's "RPG where no one has to die" gimmick: Undertale is all about player choice, regardless of if that freedom is used for good or bad.* As the first human, Thumbs, or to use their true name, Chara, put it: You are the one who pushed everything to the brink of destruction. Thumbs/Chara merely put the world out of its misery, because by refusing to do so yourself, you proved their assumption that you had some greater purpose wrong: You showed them that you did this because you wanted to see what happened, and because you believed yourself to be above consequences, the exact way of thinking that turned Flowey from the person he once was to the creature he is now. Thumbs/Chara may be the soulless consciousness of a long-dead 12-year-old, conditioned to kill even those they once cared about because they viewed you as a source of guidance... but even they are disgusted by you. 43:11 Remember the tapes down in Alphys' lab? They got sick, but it was no accident. 1:06:38 Yeah, no, they aren't spoiled. On the contrary, they're heavily implied to be an abuse victim. They're just confused, because you've just stabbed them in the back and shown them that you weren't doing this for some greater purpose like they thought. They tried so hard to help you because they thought you had some greater goal, but you were just doing this to see what happened.

That moment when he goes back to play through pacifist and realizes his mistake at the end.

I've been so excited for you to release this lol

I love how he did EVERYTHING to exempt himself, I would too.

1:11:54 Every kid that did Genocide and blames it on Chara.

I really enjoyed your peaceful playthrough more. I will probably have nightmares now. Honestly I couldn't watch this video all the way through because I was crying and feeling physically ill, it broke my heart from the moment I saw Toriel die. I had to stop before Papyrus died. I understand this is a game but I was crying because of how much I love these characters and to see the suffering in this was terrible, I can't understand why anyone would want to go down this path, even in a game.

10:59 I agree with you about the waffles pancakes and French toast thing 100%. I’m not at all a fan of French toast, but pancakes slap every time.

pro tip: for the yellow spears wont hit u even if u try to let them so if they facing the wrong way to going this way u would aim the shield whatever way they are facing not moving facing.

I voted for everyone to stay alive and happy AND I’m a Phillies fan. 😠. We’re not all crazy and murderous! Philly is a great city they just opened up a conveyor belt sushi place! 😂

Hey therm I don’t know if you’ll see this but in order to properly kill “everyone” you gotta stay in one section and go back and forth and keep killing the creatures until it says “but nobody came” And all the save points in the section will say “determination.”

At the begging what Toriel said “we don’t want to hurt anyone now do we?” (4:20)

I like how people think that there’s two endings and not a lot of lore but this vid and the pacifist one proves otherwise like for example soulless pacifist, true pacifist and true genocide and lore? The last vid can explain

Hi Therm. I don’t know if you will ever read this, but I just wanted to say that you are amazing. I started watching you through Stardew Valley, but now I love all your content. Today I was feeling down and wanted to do something to cheer me up. So I came here. I watched the video and saw you having a blast and laughing. Then I realized why I love your content. You always make me smile too and you seen like an amazing person. Thank you for being here and making these amazing videos with great humor and warming environment. I truly appreciate you. So thank you Therm for making my evening better. Lots of love from Finland, Nelli. ❤️ (sorry for bad english)

"I just need chexmix and good vibes" This is why Therm is awesome and relatable

Thank you Therm. You are the reason why I watched my first ever genocide playthrough. Now im no better. Damned be you for being such a good content creator.

love this playthroough!

Bro my favorite RU-vidr does my favorite game series...I'm so happy rn

Bro did he even notice in the Waterfall area just after the undyne spear throwing thingy the encounter mark turned from an exclamation to a smiley face 💀

Hiii !! I loved watching ya play undertale, do you think you will play deltarune? It's really fun and is sort of another "version"/ "dimension" of undertale ! So yeah, can't wait to see your next vid :]

The only reason waffles would feasibly be better is that they have the syrup cups

Finally a good video to watch, thanks

Ok but the way he roasted everyone in the stream :D

He sounds like Gideon gleeful from gravity falls when voicing toriel

It would've been perfect if he interacted with the mirror and it read "it's me, thumbs"

As a guy who lives next to the Mariners' home city, I adore the two-minute tangent about the insufferability of Mariners fans

wiping away my tears every cutscene

Those awful Zelda games were based on a *s h o r t l y* ran Zelda animated series Also, fun fact, the pan is actually better than the real knife due to it being able to do 4 critical hits in a row (or a quad) compared to the knife’s one critical
