Here’s an Something that you have never had before. [Ut/Uf Undyne, Us Alphys] Either Reader being challenged/or thy challenged them, eating a chilly pepper🌶 (Either Reader losses or wins) (if you’re not able to SF, that’s fine)
You hear Spear of Justice play in the distance...I didn’t know which Swapfell you meant dear, and I usually call Swapfell Purple Swapfell and Swapfell Red Fellswap. I also added Fellswap Gold too, because I can’t help myself. xD It was a lot of fun coming up with nicknames too!! ~ Mod Goblin(Also, I put it under a read more just so I don’t explode on someone’s dash. XD I went all ham on this)
Undyne:
If you win:
You know Undyne isn’t one to back down from a challenge. She won’t admit defeat so easily. You can see beads of sweat form on her head and tears form in her eye. She glances at the glass of milk and back to you. Her arm quivers, hesitating. You just have to hold on for just a little while longer. She’ll have to break down eventually and you’re not going to lose. You WILL beat Undyne at something, even as simple as this. Finally, she gives in to temptation and reaches for the milk. However, she stops, looking down at the glass. You flash a smug grin at her. She glares at you and growls.
“This isn’t-” She starts coughing. It was like breathing in fire. Worse than fire. Tears run down her face. “NO! I CAN’T GIVE UP NOW. NNNRAAAAAAAH!!!!” She screams, slamming her fists on the table. What? Could this be?! Is she reaching her second phase?
Nope. She can’t take it. After screaming, she had another coughing fit and downed the milk. At last, you won something. She slams the glass on the table, shattering it. She glares at you through the locks of her firy red hair.
“Don’t think this is the end, human! I’ll train! I’ll grow stronger from this pain and I WILL DEFEAT YOU! YOU MAY HAVE WON JUST THIS ONCE, BUT I WILL GET STRONGER!! I’LL SURVIVE THROUGH THIS PAIN AND I’LL BE A THOUSAND TIMES STRONGER THAN YOU!”
Moments later, you see her “training” with the very same peppers.
If you lose:
She laughs victoriously as you chug the milk. As you cough, trying to cool down the fire in your mouth, she shouts,
“That’s right! You may have lost, but endure the pain! Become stronger! LET THE FIRES OF SPITE COURSE THROUGH YOU AND CHALLENGE ME AGAIN!!!” Regrets were made. She offers to train you, but those bright red, wrinkled peppers looks threatening. She watches you with expecting eyes. Do you choose life or death?
Felldyne (Underfell Undyne)
If you win:
“This is stupid, but whatever. You’re fuckin’ on, punk!” She snarls. The first few moments, she was unphased, trying to stare you down - intimidate you. She leans on the table by her forearm, still chewing on the pepper. That’s when it hit her. You can see it in her eye - a flash of fear. A flash of the realization that she may have bitten off more than she can chew. She begins to lightly tap on the table with her fist, which steadily grew louder until she started slamming it against the table, shaking it. She wasn’t going to lose to YOU. A totally WIMPY human. She scowls at you. You’ve think you’ve won?! She hasn’t even reached for the glass of milk yet! She hasn’t even thought about it! Yeah! .... Well... Except for now. The cold glass of milk looks tempting. As tempting as a demon’s deal. Her gaze darts back and forth between you and the milk. Don’t look so smug! But this spice... This burning, agonizing spice.... She could feel it course through her, igniting everything on fire. The heat raises to her face and she slams on the table hard enough to break the table. As if it all happened in slow motion, you saw the panic rise in Undyne’s gaze. The milk now was in jeopardy - her only source of relief. She screamed in panic and reached out to catch the glass. Once temptation was in her hands, it was easy to fall. She couldn’t take it anymore. She downed that glass as if her life depended on it. She wiped her mouth with her arm and glared at you.
“YOU!!! DON’T GET COCKY!! YOU THINK YOU’VE WON THIS?! FUCK NO!!! I WASN’T ABOUT TO LET THIS GO TO WASTE, SO IF YOU’VE THINK YOU’VE FUCKING WON, THINK AGAIN!” You doubt that was the reason, but you weren’t going to say that. She already has a spear summoned and she’s eyeing you like a target.
If you lose:
“HAHAHAHA!!! I CAN’T BELIEVE YOU THOUGHT YOU COULD WIN!” She cackles as you down the glass of milk. “You’re such a fuckin’ wimp! I can’t believe monsters were imprisoned by your people! Who knew all it took as a tiny pepper?!”
Scales (Underswap Alphys)
If you win:
Scales is more of a sweets person, so you mainly did this just out of curiosity. She was curious too, mainly to see if they’re as diabolical as most others say. How spicy could these things be anyway? They’re so small!At first, the pepper was sweet! It was a different kind of sweet than she’s used to, but it’s not that ba- Oh. Oh no. There it is. The spice kicked in at the back of her throat and now she’s in a coughing fit. Without hesitating, she reaches for the glass of milk and starts chugging.
“Oh, man, that caught me off guard for a sec.” She laughs. “Round two, punk. Let’s see what you got!”
If you lose:
When you’re reduced to a coughing mess, she gets you a couple glasses of milk to tide you over and calls Toriel in case you need healing magic. Or Blue. Just, literally anyone she thinks would have healing magic. Oh no, please don’t barf...!!
Razor Scales (Swapfell purple Alphys)
In general, she thinks it’s a stupid idea. You’re still going to do it. She rolls her eyes.
“I’m telling you, don’t do it.” She warns. You challenge her. She’s not doing it because it’s stupid. This is all stupid. Why put yourself in pain without anything to gain from it? Besides, those peppers are nothing compared to what she eats. You eat the pepper anyway. Moments later, she’s patting your back while you toss your cookies in the toilet.
“I told you so.” She huffs, making sure your hair doesn’t droop down into the bowl.
SharpClaw (Fellswap Red Alphys)
“FIRE CAN’T KILL THIS DRAGON, YOU’RE ON!” She barks. She devours the entire thing of peppers, leaving you with one. She wipes her mouth and smirks at you, waiting for you to take your bite. She’s not even phased. Not a sign of panic or fear. Nothing. That was an entire bowl of peppers. You’re holding just a measly little one. You sit there, realizing you have made poor life decisions. Here, at this very moment, you realize, in order to impress her, you’ll have to eat the entire pepper. Life flashes before your eyes. This was hopeless. You’ve failed before you can even begin. “What’s the matter human?” She snickers. “You realize what sort of chances you have now?”
Slash (Fellswap Gold Alphys)
She slips the pepper through her muzzle and chews. No reaction. Not a one. She blinks and tilts her head at you, waiting for you to bite your pepper. You take a bite and endure the spice. While she watches you struggle, she eats another pepper. Should she get Wine to help you? Maybe Coffee?
