The Sinister Potions

The rusty elevator, devoid of any safety measures, descended into the darkness of the concrete shaft lined with corroded support beams. Shaggy was motivated to find new clues for the gang, and Scooby wanted to be a part of it. Despite their determination, they both were shaking with fear. Eventually, the enclosed walls of the shaft gave way, revealing a new room through the elevator's beams.

"Whoa, Scoob, what is this place?"

"Rooks rike a raboratory, Raggy!"

They poked their heads out, eager to see more of the strange room. The walls were lined with pipes stretching up to the ceiling and down to the floor, occasionally discharging hot steam. Laboratory benches cluttered the space, brimming with various chemistry equipment--flasks, beakers, and test tubes filled with liquids of random colors.

The elevator arrived at the bottom. "Ding" the door belled, Shaggy opened the door and let Scooby go first, they walked around scanning with their heads every inch of the laboratory.

"This place is like MysterioTopia Scoob, what is all this equipment used for? " Shaggy said, approaching a bench.

As Scooby walked, he noticed his reflection in a rectangular shape. He passed it but then his face lit up. It was the door of a fridge with a mirror.

"RRefrigerator!" and he opened with a small sinister laugh the door to examine the interior.

Scooby stared open-mouthed as he watched all the different glassware of liquids in front of him, his eyes fell on to beaker with a red liquid.

"Mmmm, rrawberry!" Scooby exclaimed, scooping some of the liquid with his tongue. He didn't even stop to wonder if it tasted like strawberries or notice that the substance was thicker than expected.

"Ro-oh" a headache started bothering Scooby, multiple popping sounds started to occur, for some reason Scooby's field of view started to get wider. His face indeed started to get filled with eyes, some big ones, some small ones but they started covering his face and his snoot, his head started to ooze sticky fluid (probably to keep moist all the new eyes that he acquired), on his mouth, new small sharp teeth started to grow violently making him have three independent jaw lines with hundred teeth, his tongue started to split in the middle and the new tongues started to split again, now he had 8 slimy tongues and thorns sprouted on each tongue. His fur started to fall out leaving his exposed pink skin to take his place. Scooby's skin was too covered with a sticky fluid that was dripping from everywhere. The rest of his body got a little shrunk, his paws fingers grown giving him better stability. After all, what was left of Scoob was his personality, the rest was a big head filled with a hundred eyes and a mouth with dangerous jawlines and tongues, which head was supported by a small glob pink four-legged body. A true monster of nature.

"Ri hi hi, Raggy I can see youuu!"

"Oh Scoob give me a sec, I'm checking those weird letters"

"Raggy how I can see the Refrigerator in rront of me and you rehind me at the same rime?"

"Scoob what do you mean- " Shaggy turned around confused by his friend's statement, his eyes got wider, his body started to shake from fear, as he saw the abomination of Scoob. Scooby started picking up potions with his tongues, laughing at how he could grab so many of them.

"Scooby-Doo, what kind of twisted abomination have you turned into?!"

Shaggy approached cautiously, circling him to close the fridge door so Scooby could see his reflection.

Scooby saw the horrifying creature in the mirror, all his eyes were struck with fear, and every individual eye widened making himself even scarier " RAGGY A MONSTER! RRAAAAAAHHHH!" his tongues started throwing beakers and test tubes around. A Florence flash with a dark liquid got thrown onto Shaggy, splashing his face and soaking his clothes.

"ZOINKS SCOOB you made all my clothes wet with that stuff! Ugh, and it tastes like daddy issues"

"I told you not to eat stuff that doesn't look like food " Scooby's eyes just looked at the ground from embarrassment.

"Now there's gotta be an antido-" Shaggy got cut mid-sentence because the dark liquid from his clothes started shaping his clothes giving them a liquid texture and the rest of the potion that was on his skin was getting absorbed by his body.

"Woah that's weird" Shaggy Shirt from green became dark his sleeves detached from his main shirt forming a black long sleeve shrug, the rest of his shirt became a strapless crop top with black and white stripes and for the end, his trousers shrank into a black mini short, Shaggy thought "oh why I feel my ass getting cold" and he looked at the mirror to realize that the back side of his short was made from multiple strings that hold the sides, leaving his ass exposed! Even his dick was hanging around getting cold. He rushed to put one hand in front of his new shorts and one behind. His legs in a mere second got wrapped around with black belts down from the knee and tightened up forming an elegant black pair of high-heeled boots.

"ZOINKs, but why I'm wearing goth clothes?!" Shaggy almost lost his balance by saying that, Scooby was watching with curiosity the clothes of Shaggy wondering that his skinny body could not support this style of clothes, but who he is to judge he is now a monster, but then...!

The warm color of his skin started to get pale, almost as porcelain white, it quickly spread to the rest of his body, as if it was a moonlight staring him down from top to bottom, he started feeling his body heavy, filthy calories from the potion rushed to every inch of body, firstly making his face from rectangular to oval, heightening his cheekbones, Shaggy made a girlish groan of pain "Aahh" as his face was transforming, a touch of dark eyeliner and smoky shadow started getting drew on his eyes and a flash made his sapphire blue that stood out vividly against his dark makeup. His hair became pitch black and grew giving him blunt-cut bangs a little above the eyebrow while his rest was bobbed. The eyebrows became slick black and defined giving him an even more alluring look, lending a mysterious depth to her expression. The next thing he saw was his hands becoming slender and more defined, with black nails adorning his fingers.

His lips got plumped and gained a soft velvety texture, in parallel their color was dying into a black shade adding to his new gothic charm. His new beauty felt both approachable and a little dangerous, like someone who lives on the edge of shadows. The rest of his body started to bloat, giving him a pear figure, his shoulders drew in slightly but remained strong, keeping a hint of his previous shape. A comforting weight settles over his chest, and he watches, transfixed, as his pecs expand into a soft, gently rounded natural pair of DD-cup breasts, pushing up and torturing his black and white crop top. Is transformed chest featured a natural slope, giving his now-teardrop-shaped breasts a realistic weight. The nipples, in proportion to the size, sit toward the center of each breast, they were slightly puffy, with a rounded fullness that seemed soft to the touch and had a pale pink color, making two small elevations to the fabric of the crop top.

His waist and hips follow, subtly reshaping just enough to enhance his figure. His torso lengthens and widens slightly, accentuating a natural curve to his back and some excess fat around his waist. His legs grow slender and toned, strong yet graceful, with just enough shape to hint at his transformation without feeling exaggerated. But his ass was a different story... it just started stretching his shorts and the strings that held it from the back, a pulsative sensation made Shaggy jerk his ass behind and with each jerk, it was getting thicker and thicker. His pants grew tighter by the second, clinging desperately to the expanding flesh beneath them. A faint stretching noise filled the room as her body fought against the seams. The fabric bit into his skin, emphasizing every inch as his cheeks grew fuller, rounder, and undeniably larger.

He adjusts, enjoying the feeling of fullness and the natural curves they bring without making him look overly delicate.

"Woah what a fever dream " he with his girly voice, he was dizzy from the transformation "One moment I was a man and the other- " he looked himself to the mirror of the fridge " I AM A BIG TIT GOTH GIRL?" "AAAAAAAAAAAHHHH" he screamed

" Raggy you are totally alluring, rike hot rike " " Scooby said with a hoarse voice.

Shaggy grabbed his head, his thoughts were changing and an explosive headache appeared, it was like something was alternating his personality, the potion effects he thought, I gotta fight it! But his new looks were so addictive, maybe I could dominate whoever stood in my way, you and I saw that I have still my friend down in my pants. He reached to feel his dick inside his shorts, oh fella you are a little hornyy..., he smirked. But in a moment he threw his head back and had a moment of clarity.

No no no, I went from smoking pot and running from monsters to a depressed to a depressed horny college girl with a god complex and daddy issues, he said in his head.

Actually yes! A new girly voice in his head appeared. Isn't it fun! Now stay back and enjoy the ride, said the voice with a bossy tone. Shaggy's head came back into place and an evil smile painted his face.

"Oh Scoob, I think that I went through an identity crisis, "she said simpering, "I think that Shaggy doesn't fit me anymore..."

"What rou you rean?", Scooby's hoarse voice could scare the old shaggy, but she seemed to enjoy it.

"I want you to call me from now on Sheila," she said walking towards the eyes of her monstrous friend, she wasn't as scared as the first time she saw him, "We are a new duo now don't you see my filthy friend?", she touched one of his tongues and brought it close to her to hug it. " I LOVE the way you look by the way"

Scooby's taut muscles relaxed, his eyes started half-closing, he enjoyed the affection from his new goth girl Sheila.

"I wonder why people are so afraid of the darker things in life..." There's often a fascination with what others avoid or fear, whether it's exploring philosophy, dark literature, or taboo ideas.

"You are right Reila" Scooby started moving his leg up and down, this rapid move threw some of his sticky white fluids onto Sheila's face.

"Oh! Scooby doo you shouldn't have.." she said as she licked it from her lips, the flavor is mild but rich, with a hint of sweetness that lingers in her mouth, sparking a deep sense of satisfaction with each slow, deliberate taste. She tilts her head back, her breath catching a wave of pleasure rolling through her. Her eyelids close halfway, and, almost involuntarily, her eyes roll up, revealing only a glimpse of white. She's lost in the moment, her mind slipping away from anything else, her senses consumed by the rush.

A soft, breathy sound escapes her lips. "Damn that was quite tasteful, Scoob," she said as she touched her crotch. "The big fella really loved it too" She was fully erect, her dick was trying to push out of her mini shorts. "No no, it's not time for you now " patting his crotch.

"Oh Scoob they'd all be terrified of you now, but I see the real you."

"Reila I don't know if I want to stay that ray... I'm even rcared of ryself"

"My Devoted Hound, Look at how powerful you've become! You're so much more than you were before, Just go and knock this bench down!"

Scooby got the courage and went to the nearest bench, his tongues extended from his mouth lifted the bench in the air, and threw it to the nearest wall.

Scooby laughed vigorously "REILA YOU ARE RIGHT"

"I'm always right even though I've been around for the last 20 minutes " and laughed with a sinister laugh.

"But now I'm sad.." her face changed to a frown duckling.

"Rha rappend? "

"All these succulent fat milk-knockers " and squeezed her tits, half of her DD-cups escaped from the bottom side of his striped crop top, "This great globe ass-cheeks" and bounced them " But no power for me... I'm just a weak goth bimbo" Sheila was trying to manipulate Scooby to do her deeds.

"ME RE SEILA I WILL RELP ROU! " Scooby shouted with an obnoxious voice

Sheila hid her face with her pale hands and started a fake sobbing

"My beast..." she said as she raised her head, her eyes were filled with tears,(damn she is a great actress), her eyeliner was a little worn out " Would you do anything for me?

"Res anything for rou" Scobby's eyes lighten up like a Christmas tree he had an idea. The refrigerator there she could attain her power he said.

"Would you become my serva-" Sheila got cut off by watching Scoob's body starting to run away from herself, leaving her in the middle of her performance

"Where are you going!? my Monster!" Sheila was frustrated, destroyed her eyeliner for all of this, and was hell a of mad. "GET BACK HERE " She raised her girly voice but even though she was mad, it sounded cutish.

"I Rnow how to make you strONG! ", scooby arrived at the fridge and opened it with one of his tongues and examined with most of his eyes all the shelves, with the different colors of potions, an Erlenmeyer flask with an azure liquid had written on top of it: FOR IMMENSE POWER. Scooby grabbed it, turned around with his disfigured body, he locked on with most of his eyes, and started running towards her.

"No, no, no! Scooby, STOP!" her hands projected in front of her trying to stop the mighty beast, Scoob realized that was going to crash into her but he stepped on one of his tongues, he tripped and became a ball of eyes rolling but he managed to stick a thorny tongue out just to keep the potion from breaking, he was determined. Sheila was so scared that froze in place and watched her doom coming to her, she instinctively braced herself. The sound of the eyeball was glueish and white liquid was trailing the path, but it started slowing down, and almost in front of her Scooby halted with the potion right up her face.

"Pheww"

"RI He he" Scooby splashed Sheila in the face with the potion " Row rou get rower!"

" YOU STUPID TONGUE OCTOPUS WHAT HAVE YOU DONE"

"Rook Rook " Scooby frowned but desperately showed with the stare of his eyes Sheila's hands "ROWER LIKE YOU ASKED ME"

Sheila's hand just popped a vein.

As she stood on the ground, with a glimpse at her forearms, saw her veins pumping and getting refined within seconds. Terror got painted on her face, the change was happening and she would lose her beautiful body. A burning sensation was surging through her veins all over her body. Her stomach started aching as if she had thousands of hours of core training, her weight started drying off her body. She no longer had the elegant curves that were flowing from her chest to her hips. Rough lines formed, carved her skin, and square shapes appeared in her now-in-the-past tummy, shaping an incredible six-pack!

"DAMN, YOU SCOOB!" she tried to reach him, she raised her left hand but immediately it swelled, the bicep thickened and the forearm grew dense and dropped into the ground as her shoulders couldn't support yet the weight of it.

"Oh My GOSH, What's happening to me! " she shouted with a whining tone, Scooby took some steps back scared by the half-transformed Mistress of his, her frame started to fill, the delicate definition in her shoulders broadened, her collarbones widening as her neck grew thicker and her shoulders became angular, supporting a much larger, more commanding presence. Scooby was worried none of his three jawlines or tongues was in sight, he was just watching with his mouth shut and his 200 hundred eyes trembling.

Sheila got up on her legs, her ass was still intact as well as her boobs and legs, but she was a one-handed transformed bimbo, with an hourglass shape, cause of her six-pack. Pain from sore muscles started burning her legs, internal sounds of muscle stretching began to occur, and they started slowly lengthening, her overall height from 5 foot 4 (1.65 m) to 6 foot 5 (1.96 m), Sheila's heart beat faster in her chest, as a pinching pain at her legs made her shake them violently like she was being stung by hornets, her quads, and femoral biceps rose like mountains under her skin, veins popping up to feed the growing strength, as each fiber seemed to harden, carving deep lines of definition that pulsed with raw power. Some incredible calves started bulging completing her new newfound steadiness.

"Holy shit I can run a marathon with these babies", her mind started to stray from her feminine personality.

She felt her bums starting to deflate, her eyes goggled and she touched her ass with her right feminine hand in panic.

"NO, don't take my heart-shaped ass, please nooo!", her voice echoed in the room, but it couldn't stop the shrinking process into a smaller mold, it formed into a sculptured butt enviable of the statues of ancient Greece. Lastly, her pecs growled softly with pain, her breath was sharp and fast, her feminine arm was decorated with an absurd amount of inflated veins, she touched her tits.

"My milkers..." she sobbed, her chest sprang forward pulling the rest of her body, rapid changes happened, Her face began to reshape, cheekbones becoming more chiseled, jawline squaring off to reveal a rugged, masculine contour. The softness of her lips thinned, her eyes sharper beneath a stronger brow. The eyes got green and her worn-out makeup disappeared. Her hair receded slightly, shifting into a shorter, cropped style that gave her a hardened look, in line with her new powerful form. "AAAAAAAHHHHHH" A soft, girly growl escaped her lips, high-pitched and light. But as it lingered, the tone started to dip, the sound thickening and becoming more guttural, as if it were scraping against something deep within her. The growl shifted, vibrating through her chest as it resonated with a new depth, gaining weight and timbre until it sounded primal and powerful. A growl that rumbled like thunder, filled with raw strength as if it belonged to someone unstoppable. Her tits started deflating like balloons, with air escaping her pale puffy nipples, flashing Scoob, but at the same moment, her chest was swelling with muscles, reversing the deflation her newly shaped pecs were rising and pressing her forward with pride. A loud pop sound happened and a black-grey dust came off Sheila's body giving place to a warm ivory skin tone and a sleeveless T-shirt with brown sports shorts.

"Scooby, I'm me again!" he said with a voice lowered, resonant, and deep, carrying an authority he hadn't possessed before as Shaggy. He looked at his hand that had the last feminine characteristics, he jerked his body from one shoulder to the other and with a pop muscles pumped it at the same strength and glory as his other hand. Leaving in the past the fever dream that was called Sheila.

"RAggy are you rokay?"

"Huh, guess it needed a little push," he said as he approached the mirror fridge to see his new body.

The sight was beyond his wildest dreams, a body worthy to be called Heraclius, muscles with perfect proportions to win the Mr Olympian contest.

Shaggy strikes a pose flexing his incredible arms in front of the mirror.

"CHECK IT OUT SCOOB!"

"I'M BUFF," he said laughing like a stupid flexing meat.

Shaggy's mind was only about gym training, protein supplements, sports cars, and how to get the next bimbo under his pants, all his thoughts were so shallow and had to do with instant pleasure and how to satisfy his big muscular ego. He remembered that he had seen a goth girl in the mirror before and she wanted her badly, he knew that the solution was to get a random potion and give it to Scoob.

Scooby doo, got disappointed, his mistress was gone, and now a big buffoon was in her place, all this power for what? To lose her...

"Ohh Scoob, you look sad, and sad is bad, let me help you", he reached and grabbed a potion from the fridge, he was clumsy, and hadn't got used to his new body, grabbed a tongue of Scooby's mount and emptied a glitter red liquid. Now I am gonna get my hot mamma, he thought.

Scooby doo didn't even flinch one of his eyes, as Buff Shaggy was demeaning him, his stomach screamed and he let himself transform again.

Every inch of his monster body started to stretch outwards like he was losing his realistic dimension, his body started to rip and all the fluids from his body drained and fell to the ground.

The pulling stopped, and in an instant, every point of his body slingshot to his center creating a giant red glitter bomb.

Buff shaggy coughed and waited for the glitter cloud to settle down.

Scooby doo has been transformed into Jessica Rabbit.

A porcelain-like skin figure, with ruby-red lips, with a glittering red dress with her drawn famous curves. Scooby opened his now-violet eyes, fluttering long lashes. His voice emerged, no longer the goofy drawl of a Great Dane but a sultry, velvety tone.

"Ruh... I'm not rad... I'm just rawn this way...", he was disoriented by the changes and his chest was now heavy, rike my mama's drooling tits, he thought.

"Haba Haba" Shaggy's jaw dropped, and his pants raised, his desires were unsatisfied now one transformation ago.

" How do you even pack these tits in this dress hot stuff? Can I hold them for you?" He tried to seduce her

"Well, aren't you a smooth talker? But I've got a few more tricks up my sleeve than you think. Try again, handsome." Scooby was amazed by his voice, he now could form clever sentences without missing a beat and with crystal clear pronunciation. But his mind was between riding Shaggy's cock, which made his inside drawing tingle, and getting back her mistress Sheila. Maybe he could devour his dick and bring back Sheila, but she enjoyed torturing Shaggy's stupid mind, he felt superior something that he had never felt in his life.

"Try again what? " Shaggy was so clouded by her statement,

"If you want this, " and he squeezed her tits upwards " you have to make me want you big guy " Her tone was sultry and sinister.

"Is that all you got? " she coming close to buff Shaggy brushing her hands on top of Shaggy's pants.

Shaggy face turned red from anger and shame " I WILL SHOW YOU BITCH WHAT I"VE GOT"

and he ripped all his clothes

"Oooohh *she giggled*, normally I wouldn't give in so easily, but I can make an exception for something this big ", Scooby's plan was on the right track...
