I fear no monster. But that thing... (scoot) *OMEGA TEMMIE* It scares me.

The fact that temmie replaced roles with flowey makes me scared

My face went like this: :D *after seeing omega temmie* Then it turns like this: D:

Can we just appreciate how happy looks this Gaster?

Nastablok is so cool when he is a robot

Fun fact: blueberry's theme is called 'bonequarral' but this isn't blueberry's theme

Chara: *is nice Frisk: *is mean How I react: **CONFUSED SCREAMING* How they react: Just another day in the Underground.

Asgore trying to save humans from his ex wife has to be the most surprising things in this AU. Like, I mean sure Monster Kid is possessing a living Temmie but still.

Me: Omega Flowey wouldn't hurt a fly Me after seeing Omega Temmie: What is this monster?!

a mother:don't eat too much sweets kids the kids:*eats a lot of sweets* the kids: 2:34

Mettaton NEO: I have wings, so i can always have the high ground, and a laser cannon! Napstaton NEO: SPEAKERS

Alphys is wearing netherite

You just cannot make Alphys's theme sound anything but happy, no matter what it is

Undertale flowey:i kill you hahahahhah Underswap flowey:hi im flow

Frisk and chara sound kinda normal

Floweys cute

Muffet looks like a anime charicter

Why is Alphys wearing netherite armour? WHY AND HOW TO FIND THEM.

Swap sans cute yay

This is underswap a character swap with a different character

2:35 when the kid ate a lot of candy

my eyes: ( sees alphys) me: WHAT THE HEEEECK

Where is the reanimation song from

4:30 Oh yeah... Mettaton ex and neo is always my favourite boss in undertale and over undertale fan games

The intro is AMAZING

The best Gaster is UnderSwap Gaster! :D

Litterally in asgores nice form *THEME ASRIEL*

Scotland to normal ppl:Scotland Scotland to soilder: 1:22 Eglish man with dress

Awww sans is so cute

why is asgore wearing a dress-

Fun fact: the intro is apart of the Underswap themes

GEEZ UNDERSWAP YOU MIGHT BE BETTER THAN MY PROFILE'S AU! (which is nextale sans...)

Which Is Scarier, A Fish With Armor And A Spear ( Undertale Undyne ) OR A HUGE Tyrannosaur With Armor And Axe ( Underswap Alphys )

Here is a note of who swapped with who: Chara swapped with Frisk Toriel swapped with Asgore Sans swapped with Papyrus Tem swapped with Flowey Undyne swapped with Alphys Mufflet swapped with Grillby Mettaton swapped with Nap ¢@$+£® swapped with...umm.....

5:23 Undertale sans: cool brother Underswap papyrus: ??

The theme is so relaxing I mean smooth

Do you liked all songs from this video A.HECK YEAH B.HECK YEAH C.HECK YEAH D.HECK YEAH

Muffet-Grillby

Swapped undye is gonna be my best waifu

It feels weird since blue is the shortest sans but he's supposed to be papyrus version of sans so shouldnt he be taller?

Does anyone know who underswap gaster is? :< It makes total sense if he's just reversed character-wise but I'm not sure if he is a swap of another character and i just missed it.

After i look at me in this AU's...... *'ITS STILL KILL OR BE KILLED'*

Díganme qué no soy el único que Abla español y también...AL FIN FRISK ABRIÓ SUS OJOS!!! >:D

5:21 Us! Papyrus' theme is Reanimation but this is not his theme. This theme is kinda more like Sans

OH MY GOD Temmie and alphys

finally we made it home *flops onto the couch* imma just lay here

Undertale Chara:I killed everyone UwU Underswap creator:*Uno reverse card* Underswap Chralk(NAME chanell):I love everyone🍺🍻🍺
