Frisk was heading to school, skipping. Right now everyone was busy, Flowey was out… ‘practicing', Twilight studying, and her other caretakers at their jobs.
“ I wonder what we're going to do at school today?” Frisk said absentmindedly.
“Satanic Rituals,” A voice said from behind her. A chill went down frisks spine that she started to run.
She got all of one step before being knocked out and put in a sack. The most stereotypical of kidnapping devices.
“Are we sure this is the kid that has our Lord and savior locked up?” one of the grunts asked.
“If not, we'll just kill her,” The leader said dismissively, their forms covered by black cloaks. All that was left at the scene was Frisks book bag.
(One hour later…)
Flowey walked up to Frisks bag. He looked calm, as he held it up and inspected the lost object. Inwardly, however? The sun was not hot enough to accurately describe his fury. A blue star wasn't enough to describe his fury. The heat death of the multiverse was barely a candle compared to the wrath that he felt. Kratos’ rage looked like a childs tantrum compared to the burning embers growing inside of him.
Flowey ROARED. Everyone in Ponyville stopped and coward at the sound of the monstrous roar that escaped the flowers mouth.
The flowers eyes blazed with magic, a tracking spell. He picked up on Frisks Determination, it was rather distinctive, and shifted.
Channeling the timberwolves, he went quadruped and ran, magic blazing behind him as he used it to speed his legs up. He ran, not twisting around trees but bulldozing them, eyes red with not determination but pure unadulterated Rage.
He went through miles of land, feet leaving blazing pawprints in his mad dash for his charge. He felt Frisks Determination wavering… and used it to lock on.
He did not teleport, but instead used what looked like a body flicker from Naruto. He went from in a forest to standing in a ritual, and his fury only grew.
Frisk lay beaten and bruised and bloody, half a HP left and missing a couple fingers and a ear. And a leg. Ponies were chanting, and one had a knife raised.
Flowey didn't bother to examine then further, already back in humanish form. With a flicker of magic and so much rage reality cowered, vines shot out and impaled the six not through their chests only, but their SOUL.
Absentmindedly noting the six were all the traits except DT, Flowey heard Purple speak up the finished words of the Ritual. “...Rise, L-lord Chara Dreemurr…” He said.
The flower swiftly drained the six. He was not stupid however, and instead of absorbing them whole simply drained them dry before destroying their souls.
Black smoke leaked out of Frisks body before shaping into a humanoid form with eyes as black as night, with red pupils and a bloody green and yellow sweater with brown shorts covered in blood stains and red shoes “I amFree!”
“Hi Free im Death!” Flowey said, rage still burning brighter than the brightest star as he sent friendliness lasers at Chara.
“You think you can beat me abomination?” Chara said as he dodged each and every one of his attacks.
“With your lack of love and my kill count and souls? Easily. You can do one damage at a time, on a perfect hit, out of my 300,000,000 hp. You don't have the PATIENCE to kill me!” Flowey said, vines instead wrapping around Frisk and healing her as they brought her away from the fight.
“You're nothing better than a final fantasy boss that takes too long!” Chara said mockingly
“With your pathetic Determination? I have 12 SOULs worth of the stuff, you have one chance to kill me!” Flowey said, form bulging as it grew to a twice the size Omega Flowey.
Chara punched the giant flower god rather ineffectively in the face, not even doing one damage from the weak physical attack.
“Uh… Azzy, it's me your best friend to the end! Remember Azzy?” Chara says realizing that he had no chance against the Giant.
The omega chuckled. “Didn't you see Frisks memories? Sorry Friend, Azzy isn't here. It's just me. And it's time for you to END.” Flowey cackled, mouth opening and a giant beam charging.
“Oh no… not again…” Chara whimpered, closing their eyes.
Before Flowey blasted, a voice nagged in his mind. Frisk wouldn't want him to kill Chara, not when he had more than enough power to change some Data and give the psycho a happy ending.
Instead of a death beam that hit Chara, it was a transformative one. Gone was the human SOUL, taken by Flowey. In it's place was a monsters. Gone was the males human body, replaced with the body of a skeleton… not any skeleton, but a goat monsters.
The Locket was spared, a memento of this Charas Asriel. Draining the Determination of the red Soul and filling it with a little of each, Flowey gained the final SOUL he needed.
He held off his ascension just yet, wanting Frisk to see a familiar face instead of whatever form he was given when she woke up. Taking Chara with him, Flowey teleported the three to just out of Ponyville.
Once there he filled Frisk's Soul, just a smidgen smaller than Charas, with the rest of his red DT and used the rest of the other colors not in a SOUL to heal her fingers, ear, and a sixteenth of her leg.
He'd have done more, but the Flower felt… drained, going from almost a double gods worth of power to just singular is a rather jarring difference.
Trapping the newborn monster in a cage of stone and magic for now, Flowey curled around Frisk in his little Flower form and fell asleep with the two in a vine cocoon.
After a moment Twilight appeared to see the three sleeping figures. “What is going on?!”
(The Next Morning...)
Frisk was whimpering as she tried to make a leg out of determination. Her efforts were in vain, the red energy flickering and instead making a pegleg sword.
On another bed was Chara, restrained with a couple handcuffs to horizontal poles jutting from the wall. He was silent, looking down at himself. He didn't know whether to praise or curse the flower for stripping away his humanity and turning him into a monsters, even a boss one!1
“Chara why did your mean followers have to hurt me so much…” Frisk whispered to Chara as she fell on her face again.
Chara looked down and away. He was… confused, emotions whirring around inside if him.
“I forgive you for being mean… it wasn't your fault.” Frisk says as she wobbles over to Chara and Pats them.
Chara flinched away, not deserving in his kind of forgiveness or pats. Frisk looked on sad at him not wanting pats, everyone deserves pats in Frisks opinion.
The two turned their attention to the Nurse as she came into the room. She looked very generic, under a similar enchantment as the Royal Guard but for nurses and doctors instead.
“Hi Miss nurse!” Frisk said childishly as she tried to get up to give the nurse a hug.
The nurse chuckled, catching her and putting Frisk back in her bed. “Sweety, I know you want to walk but please don't use your magic for a while okay? Your not stabilised yet,” The nurse said sweetly, patting Frisk.
“Okay I'll stop using my magic…” Frisk said thoroughly enjoying the pets.
The nurse smiled. “It's just for a few days,” She assured. “Now, I hear that our third patient is a friend of yours?”
“No he's my friend flowey he's just gotten a lot more powerful and got to be a real boy now!” Frisk said, unknowingly taking a small dig at Flowey.
The nurse blinked in confusion. “Um… ‘he'? The patient isn't the savior Flowey or male…” The nurse said in confusion.
“Yes he is he saved me from the mean people that wanted to bring about the end of the world!” Frisk said unintentionally leaving out the part where Chara would be the one to end everything.
“I'll just show her to you, will you be alright alone for a moment?” The nurse said first to Frisk before directing the second half at Chara. The new monster nodded, and the Nurse plucked Frisk from the bed before heading out into the hallway. Frisk hums happily as she was carried to what she believed to be Flowey.
When they got there Frisk saw a strange site. It was another human, with tannish skin. She had her hair in low pigtails, the hair a light dirty blonde. Because magic. It also had a flower near the front on the side of her head. Her eyes were closed, and she seemed to only be wearing a hospital gown.
Frisk immediately noticed the familiar feel the girl gave off and darted to her, hugging her. “How did you become a girl and human!?” Frisk yelled out forgetting her manners for a bit.
The new human groaned, green eyes fluttering open. “Whu…?” She mumbled groggily.
“Does this mean you're going to be my big sister now?!” Frisk said excitedly jumping up and down.
The roughly ten year old in body groaned. “Frisk, quiet down a little… my everything hurts…” the girl mumbled, shifting onto her side in the bed.
“But you're human now!” Frisk says losing her balance and falling face-first on the bed.
The girl blinked. “Wha-... Oh, right,” The now girl said, having needed a moment to remember what had happened. She brought Frisk close to hug and comfort her, whether she needed it or not. Spoiler: she did.
Frisk snuggled into the Comfort even though she put up a good fast day to be happy and go lucky she didn't like not having both legs.
