Temmie in this AU is just about the same as in Underfell. They wear a dark red pinstripe suit and a large glass monocle. They most of the time act friendly and help you in puzzles, but when money is also on the table, they choose money over you.

The "Enemy Approaching" replacement! Not much to say about it.

Struggle for Survival.

* I always have to make sure everything is fine in this hell ridden place.
* But those pesky froggits, never know when to learn about silence.

(Temmie flees the scene as soon as they hear the voice...)
(Leaving you stranded, to face the source of it.)

(!)
* ... A human?
* ... 
* It's been a while since I saw one of your kinds, and you look relativelly familiar to...
* ...Nevermind... That's in the past now. 
* Thus far, only two things are important.
* First and foremost, you seem to be unharmed. Or, at least, you are capable of walking, or crawling, doesn't matter to me.
* Second of all, I need to know how strong you are.
* The former I can already tell. And as for the latter?
* Well... You will have to prove it to me that you are worthy enough for a place like this.
* So, come with me.
* It's time for you to run the Gauntlet.

Asgore isn't as cruel and heartless here, but still keeps his harsh actions. He shows a little more empathy in him, and he isn't that cruel to a few people.

Erbärmlicher Welpe

* Oh, darling...
* You've stumbled right into my trap.
* It's simply tragic that this drab, dull place must be where you meet your end...
* But hopefully my appearance can make it more glamorous.
* ...
* Pfft, I wish.
* But still. I need that soul of yours, so I'm afraid that's how it must be.

-----------------------------

Hapstablook lurks in the Catacombs that he has made his home, thinking about his shattered dreams. He waits in the shadows, deeming himself too gross to be seen by the public in this form... Gender dysphoria is probably the right term. He resents his cousin for stealing his opportunity at stardom and comfort in his own skin, and has grown immensely jealous. However, he has not given up; the human soul may provide an avenue to the future he desires, and he's desperate to take that chance.

Deathly Debut

Come on, Human. Don't you know how to greet a new pal? 
Turn around, and shake my hand. 
It's only polite. 

* (You grabs Sans' hand, to shake it.) 
* (Sans grips your hand tightly, with a grin spreading across his face.) 
* (Bones crack the earth all around, and some linger in the surrounding air as well.)

* well, kiddo, it’s time ya learned yaself the rules of the underground.
* lesson one.
* neva. trust. anyone! all monsters are freakin’ psychos.

* (Sans leans in close and talks quieter, his tone smug and self-satisfied. He's definitely living up to his own comments.)

* that includes me, kid.

* (He leans back again, laughing like an absolute maniac, crimson smoke billowing from his open maw.)
* (He seems ready to go in for the kill...)
* (But suddenly becomes aware of an approaching, rumbling noise.)
 
SANS!!! 

* ... 
* ah shit.

This track doesn't replace anything, it plays when you first meet sans.

SANS!!! 

* ... 
* ah shit.

* (A motorbike strikes you suddenly, sending you flying out of the way. Sans releases his grasp on your hand and lets you go flying.)
* (After a moment, you stand back up and rush over to watch the conversation)
* (Papyrus parks up the motorbike and steps off about when you arrive.)

 * oh, if it ain't paps, swoopin' in to disrupt me once a-frickin'-gain. 
* an' runnin' over a child with "Bob" whilst you're at it. 

THE BIKE'S NAME IS "BEAUTY" AND YOU SHALL ADDRESS IT AS SUCH!!! 

* heh... well, tell "such" not t' murder the kid. that's my job. 

SANS, WHAT DID I TELL YOU?? 

* don't be annoying prick? 

WELL YES, BUT NO. 

* uh... don't give burgerpants socks as payment or he'll rip off my- 

NOT THAT!! THE THING ABOUT FAIRNESS. 

* that? eh, whateva. ain't important. 

THE HUMAN DESERVES TO BE ABLE TO PUT UP A FIGHT. 

* you made me give the others that opportunity, an' they just waltzed on past us! 
* right through to the freakin' waterfall! 
* where most of 'em promptly got their various appendages and organs splayed out over the freakin' pebbles.

 SO?? 

* the captain's expectin' me to actually do somethin'. you made me join the guard!! let me do my guard duties!! 

BUT SANS!! I... I SPENT SO LONG ON THE TRAPS... 

* uh... 

I DON'T WANT THEM GOING TO WASTE... (SIGH) 

* ... eh, whateva. fine. we do it your way. 
* but if your traps don't deal with 'em... 
* i ain't gonna shy away from gettin' my hands dirty. 

THEN SO BE IT.

-----------------------------

Papyrus has his normal abilities, but appears to be far stronger with them than he is in Undertale. He sometimes works with Undyne to create machines and puzzles for the Underground. He's too afraid to join the Guard out of fear that Sans would bully him for it. He often cooks with Muffet and has attended the occasional tea party with her too (but he won't admit that to anyone). Papyrus is trying incredibly hard to come across as cool, hence the outfit he wears and the motorbike. The bike itself is named "BEAUTY", but Sans calls it any stupid names he can think of (usually he calls it "bob", but he's not afraid to switch it up), much to Papyrus' dismay. 
Papyrus initially wants the human to go through his traps just to see what happens, but rather swiftly decides he doesn't want them to perish. So he protects them as much as he can from his brother.
The scars on his eye are a sore subject for him. Even mentioning them will completely ruin his mood.

BEAUTY AND THE BADASS

* heya, kid.
* y've been busy, huh?
* gettin' past puzzles, befriendin' the unbefriendable...
* waltzin' through my home town like y' own the place.
* ...
* y'know, i made a promise with paps.
* if it don't work his way, we're doin' things my way.
* after all, he just wanted t' give y' a fightin' chance. 
* an', well... heh... we saw the way things went for that plan.
* so...
* i'm takin' matters into my own hands.
* ...
* i could explain why i need it, y'know.
* ya soul, i mean.
* or i could explain the... complicated history with humans an' monsters.
* could explain what's gonna happen once i get my hands on it...
* but eh.
* i don't feel like it, so...
* let's just get to the point.

-----------------------------

Sans still has his abilities from Undertale, and to some extent he remembers resets, but can't bring himself to care about them. He joined the guard because Alphys saw his fighting skills and wanted his talent amongst them, and Papyrus therefore forced him to join. He doesn't wear armour because he "doesn't need it". He speaks in lowercase letters still.
Sans is usually rather lazy and generally seems bored, but has a strange sense of malice about him. The prospect of murdering a human intrigues him, and he desires to find a way around Papyrus' rules on fairness. However, he's just trying to find the shortest route toward this; he's trying to take the shortcuts to getting a human soul, but his brother won't allow this.

eh whateva. +  to the point.

* Oh, human, child...
* Look at you.
* So afraid, so... Helpless.
* To some extent, I wish that I could comfort you, but I know my words would be meaningless at this point.
* For I am the one who has you so fearful.
* No matter...

* I hope you can find comfort in knowing that your loss is our salvation.
* And I hope you do not struggle.
* For it will hurt both of us so much more that way.

* It was nice meeting you...
* I wish I could be sorry.

-----------------------------

(Original plan was to make the Heartache replacement before the skelebro's tracks, but that later on got changed by Spudward.)

Asgore's plan was to protect Chara till the time had to come where he has to resolve with violence, and kill Chara for their soul.

Anyways, I'm not that great with long speeches, so I'm gonna keep it short: Thank you for 100 followers!

Here we are.

* ALPHYS 10 ATK 6 DEF
* Commander of the Queen's Royal Guard.
* Always stays at the HQ, but knows how to fight.

* W-with your SOUL, Human...
* We c-can finally be free.
* Maybe for once I can do some real good!
* I think we both know that Monsterkind needs it.

-----------------------------
Alright so, for those who aren't on our Discord server, lemme explain why we haven't been uploading anything for 3 months now. Basically, after we were done with the "Conflict of a Blazing Soul" track, we were planning on making the "Ruins" replacement. What's exactly the problem with that? We couldn't really make it. We asked a few people but they were either too busy to make it, or just couldn't do it. Someone is currently working on it, but they are busy with other projects aswell so we won't see it coming out anytime soon. So, apologies for the long hiatus.

Alphys Means Business

* (Undyne slams her hand against her desk, clearly not aware of your presence.)
* (It cracks and splinters slightly more than it already had.)

* DAMNIT!!!
* I should analyse what happened here...
* Find the root of the problem, figure out why combustion wasn't achieved...
* That could take hours, days even...
* But it's the safest option.
* ...
* ANYWAYS I'M GONNA ADD MORE PROPANE
* NGAAAAAAAHHHH!!!!

-----------------------------
Undyne is the head scientist of the underground, and worked with Papyrus and Alphys to help create machines and puzzles intended to trap any Humans unfortunate enough to fall down. She has always been fascinated with the effects that DETERMINATION has on Monsters, witnessing how it strengthened both their resolve and physical toughness. However, this curiosity was punished severely when the experiments inevitably went sour... She was lucky to have only taken a small dose herself, as only part of her face was lost (leading to the robotic replacement she has today).

Brute Forcing Scientific Advancements For Maximum Efficiency

The once was creator of Fellswap 2020, referred to this AU as the "Canon Fellswap", a take on Fellswap that tries to stay true to the original Underfell, but doesn't swap personalities. The "Canon" in the name isn't there to imply it as the original Fellswap, but because it is based on the canon version of Underfell. All swaps are the same as Classic Underswap.
