Badger lent over his keyboard as his screen flashed to light with brilliant colors, the sinister Flowey transforming before his eyes into the tall and handsome Asriel Dreemurr. His fingers flexed lightly as he prepared for the final battle of Undertale's true ending, however something had imperceptibly changed about Asriel's sprite... His smile seemed somehow smugger, more assured than it had ever been before...

"I warned you not to restart didn't I?" Asriel's word bubble flowed across the screen. "I told you that it would be best to simply let everyone enjoy their happy ending, but you didn't listen..."

"That's not right..." Badger mumbled as he clicked forward in the dialogue. "There's no special text for doing the true ending multiple times! Right?"

Asriel's arm raised and suddenly Badger felt his body freeze in place. From his speakers a deep, cruel voice whispered forth, "We both know how this story goes. Your DETERMINATION prevents me from ever truly winning and this world reaches a 'happy ending' which will never truly stand as long as you desire to return... So I have written a new ending."

Badger's eyes widen as from his screen a sparkling rainbow of light flies out, covering his body in shimmering prismatic light. Where the light touched, snow white fur began to grow, quickly spreading out to where the light could not reach, changing him, growing him, filling him with something other than DETERMINATION! As Badger's eyes swirl with darkness his mind is filled with new thoughts and desires, the need to control, the passion to overcome all who would stand in his way and a swelling love for... For...

"For our one true friend!" Asriel whispers. "The fallen human who set us on this path! The one who taught us what was needed to survive in this world! The one who let us realized we need-"

"The THICCNESS!" Badger whispers as his face pushes out into a feminine muzzle.

"The... What?" Asriel asks, sounding suddenly confused.

"I love... THE THICCNESS!" Badger gasped, his broad chest swelling as two large breasts pushed forth from beneath his newly sculpted pecs. "I shall spread thiccness across this world till all appreciate its juicy power!"

"That's not even close to what I meant!" Asriel cried, "What is happening to my spell? Why is your computer saturated with gender transforming energies and huge thigh magic!?" His eyes narrow. "Are you some sort of huge pervert?"

"No..." Badger blushed as between his suddenly rapidly expanding thighs that had defined him as a 'he' became suddenly much more of a 'she' situation. "Maybe?"

"Why are you humans so weird!?" Asriel moaned as he began to try and correct his spell, watching in dismay as the matching robes Badger had been dressed in quickly transformed into a fluttering mini skirt and star spangled stockings which left absolutely nothing to the imagination. "Quickly now! There's still time to correct this and our plans can still be salvaged! I just need you to use your magic to connect to mine and I can-"

"Board now." Badger shrugged and with a thought banished the spell holding her in place. "I'm gonna need more magic to help spread the THICCNESS, but you seem kind of... Pushy so I'm just gonna grab my friend for that. BEY!"

"No wait!" Asriel shouted, "I can save your manhood and help you bring darkness to this world! I just need you to-" But whatever he was going to say was lost forever as Badger closed the program with a sparkle of magical energy and replaced it with her discord account. Mr. Shouty would never appreciate the TRUE joys of THICCNESS, but she knew the perfect person who would! Someone who was always happy to help her create transformative mayhem and would definitely be open minded about this new direction for their collaborations... With maybe just a bit of work…

(A few hours later)

Badger heard the knock at her door and beamed as she prepared a quick spell to disguise herself in her old form before opening it with a cry of, "DUHAD!"

"Hey buddy..." Duhad waved awkwardly, stepping through the doorway as Badger waved them inside. "You, uh... Okay? You said there was an emergency and that I had to drop everything to come help you." They looked around the darkened apartment. "Also since you never invite me over, I sort of figure there must have been a fire or something, but you seem... Happy, which is good don't get me wrong, but I'm a little..."

"Confused?" Badger asked, barely able to contain herself as she allowed her disguise to fade. "Don't worry, you'll understand soon! But first, you're a fan of Delta Rune, right?"

"Weird question, but ya I love that game!" Duhad nodded. "Hey, why does your voice sound so strange?"

Badger ignored the question as she weaved together a spell and moved her hand to either side of Duhad's body. "And you love that thicc little lady, Ralsei?"

Duhad sighed. "Dude, I have told you before, Ralsei is a guy."

"Not anymore you're not!" Badger laughed and suddenly Duhad was surrounded by dark magical energy, reshaping their clothes into an open chested robe and a pair of sparkling stockings. "In MY version we are ALL the THICCESST of girls!"

"What's going on!?" Duhad demanded as their voice raised to a squeaky lilt. Under their new robes a pair of large, heavy breasts burst forward, covered a second later by a layer of soft black fur which spread out over their body like a downy carpet.

"Just look and see!" Badger cheered, lifting Duhad's robes to reveal thickening thighs and a soft little pussy, already aching for attention. "I needed someone to spread the good THICCNESS across the world and I couldn't ask for a better assistant and partner then you!"

"W-What do you mean?" Duhad stammered as Badger pushed her newly manifested hat down over her fluffy ears. "W-What is going to happen to me?"

"I'm going to make you my perfect assistant, silly!" Badger purred, nuzzling her face into one of Duhad's ears. "Then we are going to take on the world!"

"W-Why would I help you with that!" Duhad gasped, feeling her body tremble as Badger leaned into her back, soft breasts and even softer hips pressing against her back. A-Are you going to twist and corrupt my mind!?"

Badger giggled and leaned in closer, whispering. "Why would I do any of that when we both know all I have to do is get... Just a little... Closer... And ask reeeeeelly nice?"

Duhad gulped as Badger's muzzle slowly slid up next to hers. After all... She wasn't wrong!

The world was DEFINITELY doomed to a very THICC new age!
