!Undertale reacts to Sans, and Asriel's Boss battles! (Please read description) 

Future me here: I HATE THIS- its just so old, and bleh, and cringy- I was so lazy too, LOOK AT ALL THE PARTS I SKIPPED AHH- Plus I didn't know any lore for the game SO THE DIALOGUE DOESN'T MAKE ANY SENSE! If you are just now finding this I apologize for making you sit through this terrible video 😞✋

Everyone: *Shocked on seeing Sans's attacks Chara: Ah, the good old days

Me: try to play pacifist My friend: force me to do a Genocides Routes Me: *chase My Friend*

I find Sans interesting because he is the only monster who uses Karmic Retribution. You can see the little KR by your health bar. Because of his stats, he is technically the easiest boss, but because he uses Karmic Retribution it deals more damage. It’s karma. And because Sans majors in quantum physics he knows about timelines. How he remembers them isn’t really explained though.

Me when I saw Azzy’s battle: AAAAAHHH THE STARS ARE ATTACKING ITS THE END OF TIMES

8:35 Asriel was the only one who could never hold back any tears. Good job on this part.

Sans fight was much much much Harder than Arsriel ;-; If was heck hard took me sometime to memorize all attack

*memories r flooding back...*

2:20 Sans: I turned off and on the lights while changing my attack

Can you do Afton Family reacts to Omega Flower and Asriel boss battles?

Megalovania: *starts* Me who has been watching/playing Undertale Last Breath and listening to its OST way too much: so slow paced and boRiNG!

Chara: all my fault.. Canon Undertale: well, uhm, yes- but- uh- no-

0:10 Welcome in the Club, buddy.. *;-;*

Everyone(sans boss fight): oH MY gosh- everyone(Asriel boss fight): oh ok lol:

Flowey: idc sans is a noob Me reacting sans vs flowey sans just beating flowey Lmao

Actual reactions for Asriel having infinite attack and defense. Clap clap.

That way Chara said "such great memories" I wanted to break the fourth wall enter the screen and beat Chara until it's a bloody mess

*Chara looking at Asriel crying* Asriel: i_i Chara: : < Asriel: i_i Chara: : < Asriel: i_i Chara: : < Asriel: i_i Chara: :)

0:33 Chara trying to shake off the bad memories be like: Yeah might wanna NOT do that creepy smile while you do that, people will start to think you're insane. Or a masochist. Try copying Sans and Frisk's smiles, they've got it all down.

Future sans: my special attack is different than sans. Watch. "Grabs hold of the katana of determination and cuts in mid air making a cannon blast" that's my special attack

Love your vids!

Yo I legit laughed my head of when I heard your outro lol I LOVED it

Bless the darkness that caverns your soul Frisk. CONFESS YOUR SINS MY CHILD!

Oh mah gaw ;-; I couldn’t see it because it took forever to load but it was worth it! :D

The cutscene in the asriel fight is the saddest part of the game to me

Ah, the sweet memories of me sitting in front of my pc for 5 hours, trying to beat Asriel.

Bro idk why I can’t hold my tear when the past His Theme

Can you do Aftons or basically any fandom at all reacts to Undertale: Frisk Vs Sans and Undertale: The Aftermath. These animations depict key moments within the Undertale storyline. Frisk Vs Sans takes place during the final, adbandoned genocide route. Frisk's determination begins to falter, but Chara pushes them forward. So they fight Sans, their determination slipping away, their movements become slower and their attacks less powerful. Their memories of the past Sans fights becomes useless. They die to Sans multiple times before almost managing to stab Sans, only to get slammed into the roof and floor multiple times, and then fall. Sans pulls out one of his bigger Gaster Blasters, which represents his determination, and in turn reminds Frisk of what used to be. Their friends and family, their perfect happy ending. And then Sans blasts them. The Aftermath takes place where Frisk Vs Sans had left off. This takes place in the following Pacifist Route, where Frisk straight up apologizes to a confused Sans. After this Pacifist Route, a True Pacifist Route happens, although it's not shown in the video. Three years pass and the comic known as Endertale begins.

I really love your design for mettaton and sans

Sans:just hive up... i did Also sans:don't look don't look don't look

Why does flowey look cute in glasses

I mean...I don’t know how I got here from looking up a Rejuvination react, but hey ho this is epic

You know the part where sans's keeps glowing? THERE SHOULD BE A TROM-BONE!!!!

The person who made this vid skiped some parts of the sans fight xd

Undyne: How are you doging?!? Me: just dont be that lazy of a monster, EASY!!!

Undyne: how are you dodging Sans: it's a very complicated process I move when they attack

I dont want to say that im mr i know everthing but actually papyrus knows what a gaster blaster is

I just realized something during the lost soul phase, papyrus still has his font sans, has the default one. The one he used in the mettaton resort where he says “y o u ‘ d b e d e a d w h e r e y o u s t a n d .”

6:06 Jonathan: My heart resonates...! SUNLIGHTO YELLOW OVERDRIVUUUU! **If you were a Jojo fan you would get this**

Sans: "you really like swinging that thing around" Me: ... ARE YOU fLirTiNg wIth mE!?!? NOwz Not The fUckinG tIme SaNDs

Aww your a cute bear! :0

Undyen: how did you dodge!?! Sans: I walked alittle to the left?

I like how no one questioned sans saying “our reports show...” you think they’d be like “what reports” atleast

Therapist:show me what makes you rage Me:shows theme battle in the video* Therapist:Thai is gonna be hard ;-;

Pretty cool video! Nice character variety, although it is kinda weird that you picked metaton over toriel or asgore (although to be fair it's rare to find a video where asgore says anything unique) I like it tho, makes your video stand out over the more generic rouster. Good stuff all around ^^

"but why attack the human?" - _the second boss monster to attack you_ to _the final boss monster to attack you_

The ones at the top are F L O A T I N G

Everyone: how do you dodge? Sans: I MOVE TO DA GOD DANG LEFT

Papyrus: What are those things? Me:You literally saw them at the beginning of the battle!!! Also those are Gaster blasters 2:37

When the Megalovania started Alphys should have said "THIS IS WHERE THE MEMES COME FROM"

Pls let them react to sans memes- Aside that I love the ending- and ur outro xD

Is it weird i watch sans fight on loop and i never get tired of it

Time for them to react last breath... DO IT 🔫 :>

Future sans:.....I'm glad that I don't need to see anymore genocides.

I LOVE UR VIDS :3

Undyne : how are you dodging?!? Sans : uhmm its called sliding to the left and right..?

OMG HI!!

Sometimes when they react their reactions are too early.

What I said when I went back to see asriel: AZZY! LONG TIME NO SEE! itsbeentwominssinceyoutriedtokillmebutanyway AZZY!

Cool vid! By the way, can they react to Toby fox video game story time? I know it doesn’t fit it to the storyline of undertale, but it would be cool if they could learn about their creator.

I thought when Chara asked Asriel if he did this after he responded yes they would say "Im proud"

2:14 bruh you died and you cried and i enjoyed it :D

Could I be in one of ur dare vids :0??

Sans looks like he doesn't give a crap anymore or just looks like he is used to it

This video sucks are you sure about that it was fricking awesome but i have to do school work nooooo btw keep up the great work

i have an idea take your top 3 favorite boss battles then make undertale react to it

No one realized asriel was crying until the last minutes

Chara: why im always the evil one Im not even evil until frisk starts genocide and kills enough >:^

Chara? Chara! Wake up! Its just a dream. Chara you’re innocent. You’re not evil I know this! Chara. *You here Asriel cry. *You feel bad. *You are getting close to death...

oh and wow i underestemated you soooooo much

I've done the Asriel boss fight twice So- True pacifist is da best =>

Papyrus: look at my amazing moves! Me: yeah soooooooooooooo terable!

Me when hears His Theme: *Starts Crying* Also me:😭😭😭😭😭😭😭😭😭😭😭❤🧡💛💚💙💜

I luv the music of asriels boss fight soo catchy >w< Moral lesson: never go to the genocide route of the game cuz you might kill the characters agin ;(

Logic: Flowey needs glasses but Asriel doesn't

1.Sans looks like Isabelle from animal crossing. 2. Flowey Looks Like that one/rich smug kid in school

Chara is smiling throughout me: *wait thats illegal*

Undyne: How do you dodge Me: You move your feet

Now ik how to do pasific route and I wil NEVER ado genocide only ONCE to TRY and beat OMEGA FLOWEY and SANS

ASRIEL fight made me cry 😢

The funny thing is… “why attack the human?!” I think they forgot they ALL have attacked the human at some point… except alphys… even TORIEL attacked the human. Even if not for malicious intent.

Howdy! Player, are you there? It's me, your best friend. *T H E F E E L S*

Nobody noticed that sans said “just give up what I did”

Me: **sees Omega Flowey** Also Me: **flashbacks to fighting him myself and seeing how flipping ugly that THING is** Me Again: **starts waving hands in the air randomly** Just Me: **Has a literal PANIC ATTACK just from seeing an ugly weed-**

Asriel fight make us cry every tim

"pap.: But why attack the human?!" Me: WTF MAN U TRYIED TO KILL ME TOO! =^=

i find it funny how most UT gatcha AU's forgive Asriel but not the "player" you know considering they *BOTH* did *EXCATLY* the same things, Flowey killed everyone multiple times over probably even more then the player and the only reason frisk gained control was because he got bored enough to let another day pass. his dialog in genocide even states as much quote "As time repeated, people proved themselves predictable. What would a person say if i gave them this? What would they do if i said that to them? once you know that's it that's all they are. It all started because i was curious. curious what would happen if i killed them. (") I don't like this, (") I told myself. (") I'm just doing this cause I HAVE to know what happens.(") HA ha ha what an excuse!" end quote

2:13 Same Asriel 8:35 NO! THE CINNAMON ROLL IS CRYING! 1:06 Don't blame yourself Chara you are innocent(yes they killed a few but like only 4 or 5 you killed over at least a hundred)

WOAH IS THAT UNDERTALE :D

we all change our clothes and do our hair so if people keep their oc the same they need to take a shower! so i change my clothes every video so its ok to let your oc change its clothes

Is nobody going to notice what sans said? "I give up I did"

Why is frisk making my the same face for like, FIVE MINUTES. HOW IS SHE DOING THIS.

BEFORE WE START I ONLY CAME HERE TO SAY THAT ONLY MERG KNOWS THE SECRET BOSS NOT THE NITENDO SECRET BOSS THE ARTISIAN SECRET BOSS

i cry everytime on asriel fight lol

🤩😍💕💞♥️💝💖🌹awesome stars u should try Natural Betty Origin,Willow Tree Underverse Resistance,Everything Black Dreamtale,Rewrite The Stars KillerOuter animation

Alphys i swear to god sans was once a scientist too you should know this 4:30 NOoOOOOooOOOOOoOooooOoooooOoOOoOOOoOoOOOoOOoOoOoOoOOOoOoOOoOOOooooooOOOoOOooooOOOOOOOooooOOOo 4:36 "i dOn'T wAnT tO sEe AnYMorE" I have bestood great gift upon you papyrus (who is named after a font) you are now blindus

I think sanses special attack is to cancel out his opponents turn until the battle us over or the opponent gives up or he gets tired and leaves

IM NOT CRYING U ARE 😢😭

chara: waht a great memory frisk frisk: chara the name of the player is kira so its not me

just throwing this out there Papyrus CAN use the gaster blaster according to in game dialog
