22-Year-Old, Tammy, was a total fangirl of the Sonic the Hedgehog franchise much like everyone else including other girls. She doesn’t mind the new and current game, but she has loved playing the classics since she was a kid. She used to play classic Sonic games with her old friends and would most likely meet them during their playdates in childhood. However, she doesn't think she's every played glitched or hacked games before, nor even games revolving around Transformations of all kinds including people turning into the opposite gender and sometimes the same gender.

Recently, following the other girls' disappearances, many people in her hometown began spreading rumors and gossip about the reason behind the disappearances was that a certain demon Demigirl who wrote strange and unusual fates of the girls in her stories she has written, including those whose souls are trapped in their wrong bodies, for about an entire month, each girl with body, mind, and soul were transformed into EXE, Oddities, and other kinds of the opposite gender of every type. Tammy couldn't forget these rumors to this month, that she doesn't think she really wanted to play any of them because of that…that was until one day, one "Experience" would end up changing her life forever...

On a Summer Afternoon, Tammy had just finished playing Sonic Unleashed on the unofficial PC Import, Tammy had noticed something out of her peripheral vision, a package was delivered on her mailbox. Fortunately, she had completed the game by herself, so she headed outside.

“Ooooooh, I wonder if it’s another Sonic game I got recommended to. Hopefully it’s another nostalgic one I used to play as a kid.”

Said Tammy as she expected. Surprisingly to her, the only thing in the mailbox she found was a small package that came with an envelope with the front that reads…
 

“READ ME.

FROM: KYLIE. TO: TAMMY”

Tammy, out of curiosity, took the package from the mailbox and took it with her into her house. At home, Tammy opened a package and out came turned out to be a CD Case for computers back in the 2000's and the envelope inside was a note. At first, when she looked at the note, Tammy realized it was in fact from her best friend, Kylie, as written in front of the envelope, whom she hadn't heard from in 2 weeks.

“I knew that package was from Kylie! I still wonder what happened to her?”

Tammy said as what she found weird was how her handwriting looked. It was badly written, scratchy, and somewhat too hard to read. It was as if Kylie had struggled writing it down and quickly did it in a rush. Kylie’s note reads...

“Tammy,

I can't take it anymore! I had to get rid of this by myself somehow before it's too late, and I was hoping you'd do it all for me...but I can't, because he's after me, and if you don't destroy this CD Disc, not only he'll come after you too, but he'll take you over and change you in WAYS you can't imagine. He's way too fast for me…

Please, Tammy, destroy this god-forsaken, hellish disc before he comes after you and changes you! It's too late for me because I'm slowly on the verge of losing myself.

Once you destroyed this disc, you'll destroy him. But do it quickly, otherwise he'll catch you and then drag you away! Don't even play this game, it's what he always wanted, please…JUST destroy it!

Please…This is my last will because this is the end of me…

-Your old friend, Kylie”

“Well, that’s certainly weird, but it’s also feels suspicious…”

Tammy thought to herself. Even though Kylie was her bestie since childhood, she didn't do what she asked her as she put down the note Kylie wrote…

“I don’t think that a simple gaming disc would do such a thing to her. After all, it’s only just a game…”

Tammy thought to herself again…but what she didn’t know that the disc wasn’t all “Simple” and that “Game” that changed her bestie would lead to Tammy about to make a BIG MISTAKE of her life…

Tammy looked at the disc and it looked like any normal computer CD-R disc, except it had a black permanent marker written on it saying…

“SONIC.TG”

… But it wasn't anything like Kylie's handwriting. So, she must've gotten it from someone else, she suspected it to be a thrift store, or eBay, or what she suspected was that she reluctantly got from the same Demon Demigirl that people spread rumors about. When Tammy saw “SONIC” written on the CD, written on the CD, she was very excited to play another Sonic game, since she's a huge Sonic fan after all.

“Aw, what the heck? Could be another game I used to play on the PC! Let’s see!”

Tammy said in an excited tone as she went up to her room and turned on her computer that had a CD player plugged in to the PC. Then, Tammy put the disc in and installed the game. Once it was finished downloading, she clicked the application to play. But she knew little that she should've listened to Kylie's advice. That would have spared her from what she was about to go down…

When the Title Screen appeared, Tammy noticed that it was the first Sonic the Hedgehog game even though it was "666" instead of "SEGA 1991", to her amusement and excitement due to her fascination with the classics and how she cherished the memories of it. However, the first thing she noticed out of place was when she pressed start for a split second, everything turned black, the hand was obscured by the dark, and there were two red, menacing-glowing red dots staring at her. Tammy was rather disturbed and suspicious by the image, though she figured that it was just a glitch as she brushed it off as one, so she forgot about it. After cutting to black, it stayed for about 10 seconds, before another thing happened that made her feel more suspicious about this game…

Tammy noticed that it was a save file select screen from Sonic the Hedgehog 3 & Knuckles Collection.

“What the fuck? What was this save file select doing here in the first game??”

Tammy thought to herself as if she then noticed another thing. The background was a dark cloudy sky texture of the Bad Future section of the Stardust Speedway level from Sonic CD, but bloody red, and there were only three save files. The music was playing "MENU1" by the composer, Mihaelkyeah/Kyu Sawamura, a very creepy soundtrack for a file select screen. But the image for the save file, where you see a preview of the level were on, was just red static for the three.

What intrigued Tammy more were the characters for each selection, showing Tails, Knuckles, and to her surprise, Dr. Robotnik aka Eggman! This strikes her as odd because for people who are unaware, it is impossible to play as Robotnik in the classic Sonic games. So, Tammy didn't expect to see a playable Robotnik here.

That's when Tammy suddenly realized that this wasn't a glitched game, it was a hacked game!

“Looks kinda creepy…”

Tammy said to herself, but as a “Smartest Gamer Girl”, she wasn’t scared, or at least she tried not to be…

“Oh, come on, Tammy, it was simply a hacked version of the game! It can't hurt a fly, right?”

Tammy said as she shook off the uneasy feeling, she picked File 1 and chose Tails, but when she did it, the game froze for 5 seconds before she heard a familiar, creepy laughter sound right as it cut to black.

The screen stayed like that for 10 seconds before showing the first, typical title level. However, the shapes were different shades of red, and the text said “HILL” without any Act titles below. The screen faded as the level title vanished to reveal Tails in Green Hill Zone. But the music was different, the peaceful melody was played in reverse in an eerie manner. Tammy started playing Tails and controlled him to the right, like you would in any of the classic Sonic games, but the odd thing that Tammy found was that as Tails ran along the level, there was nothing but flat ground and a few trees which seemed normal at first for a minute or two. Then, suddenly, Tammy noticed and stopped to see two dead critters, one on the ground and the other on the tree. Tails had a shocked and pitiful look on his face. One that she never saw him make one before. When Tammy continued to control Tails along in the level, he kept having a worried look on his face and then, he started staring at her. This caused Tammy to think to herself…

“Is he…looking at me??”

As Tails kept moving, he saw more corpses of animals everywhere. Tammy was shocked to see how they all died; they looked like somebody killed them. Some of the corpses have a bit of blood and guts everywhere left behind. Tammy was feeling nauseous and petrified when she saw this massacre, and apparently, so did Tails. Tails then looked with a petrified look, as if he was suspecting her…saying

“Did you…Did you do all of this…?”

“What?? I-I didn’t! I never touched any of these creatures!”

Tammy said at the state of shock and confusion, wasn’t sure if he was misunderstanding…

After a few more seconds as she made tails press on, there were no more animals there and the music completely stopped. Tails ran up the hill and saw that “Sonic” was there on the other side of the screen with his back against him and eyes closed, and strangely, his shoes are dark gray instead of red. He was acting oblivious to Tails' presence.

As she watched Tails move slowly towards Sonic, Tammy began to have a growing feeling of dread as Tails grew closer to “Sonic”.

“I knew something bad’s gonna happen…”

Tammy thought to herself as she felt that Tails was in danger. As creepy background SFX played when Tails is approaching him. Tails were inches away from Sonic before he stopped. Tammy's heart was racing as if she was having a panic attack, as she felt the urge to tell Tails not to come any closer.

Suddenly, in a split second, upon approaching “Sonic”, his eyes were open, but his pupils are red just like in the title images, and his sclera are black.

“No…Not again…”

Tails said as the screen cuts to black for 7 seconds before the white text with one of the fonts from the classic Sonic games appeared, forming a message saying...

"HELLO. DO YOU WANT TO PLAY WITH ME?"

At this point, Tammy was creeped out as she said to herself…

“What the hell was that??”

Tammy didn't want to continue with this game, but her curiosity got the better of her when she was taken to a different level titled…

"HIDE AND SEEK"

This time, Tammy was on the Angel Island level from Sonic 3, and it looked like the entire place was ENTIRELY on fire! ALAN looked as though he was scared out of his wits. He looked at Tammy with a traumatized expression and made frantic gestures to her, as if he wanted to get out of the area as fast as possible and told her…

“Please, don’t do this again to me, please…”

Tammy was a little confused but more freaked out by this… He was breaking the fourth wall, trying to tell her to get him out of here and not to go on a “Deja Vu” of the same game.

“Wait, he suspected me to be the Killer when the creepy, red-eyed Sonic with black shoes was…what the hell?”

Tammy said to herself in confusion as she pressed down on the arrow key as hard as she could and made him run. As she did that, red electric sparks were formed out of the monitor and into the keyboards as she made Alan trek through the desolate forest, trying to help him escape from whatever he was trying to run from as he looked at her again in horror, as what Tammy didn't know, the strange “Side Effects” from the game was about to take effect on her.

Tammy felt a cramp but tingling feeling on her hands, as they felt like pins and needles, the slightly dark tone of fur started forming on her hands as they started growing and becoming a mannish tone, her nails then grow into black claws with two scars forming on her wrists, she still controls the keyboard during the game with her changing hands, but she doesn't know yet. The fur then spread through both of her arms as she felt an intense pressure on her arms, she thought that her controlling Tails must've made her arms cramping. As the fur then spread all away above to her shoulders, her arms and biceps bulged and bulked up as they grew masculine. The sleeves of Tamy's hoodie then began to grow tight until they broke out, exposing the manly tones of muscles. Once that happened, a pair of white gloves appeared on her bulked hands complete with a red ring manifesting on one of her fingers along with white bandages appearing below her elbows and a left arm band from above appeared on the left.

During the first changes, Tammy noticed there was a timer in the top left corner. It counted down from 10, as the remaining 9 seconds began to pass, Tammy desperately had Alan run through the level, trying to find a way to escape while trying not to notice the first phase of her transformation before the time ran out…

However, it was too late, the time went to 0, and Alan stopped running. He was about to look at Tammy and warn her about what’s happening, but he looked back and forth, cowering in fear as the words appeared on the screen…

"TIME OVER"

After a few seconds, the eerie soundtrack playing in the level stopped, the text changed to…

"READY OR NOT"

Then, “Sonic” flashed onto the screen, twitching with his eyes entirely black with blood seeping out of his eyes and his teeth yellow, sharp, and monstrous. He was more beasty than ever! The text changed again to “HERE I COME!” before disappearing, the static flashes before her eyes.

The music then changed to that suspenseful drowning jingle as “Sonic” appeared out of nowhere and chased Alan, who sprinted away from the demonic hedgehog.

But that “Sonic” wasn't running, he was flying! That flying pose his sprite made looked exactly like Metal Sonic's flying pose in Sonic CD, except that it was just Sonic with those black and red eyes and dark gray shoes. Only this time, he had the most deranged-looking smile on his face as he looked as though he was enjoying the torment he was giving the poor soul in the little fox's body as he gained up on him while the second phase of her first changes then proceeded on her body.

The dark tone of blue fur then formed on both of her shoulders as they bulked and broadened, becoming masculine, as the dark blue and dark light tone of fur then started growing throughout the shoulders to her waistline as she grew taller a little along with her spine arching to its masculine posture. The dark blue and dark light tone of the fur reached out to Tammy's torso slowly, her waistline had cracked and broadened, becoming more manly as the intense pressure applied to her chest as they started to burn a little. With the dark light fur reaching her chest, both of her breasts receded in a matter of seconds as Tammy moaned. Her breasts then quickly become flattened and then morphed and shifted into a pair of masculine pecs. A piece of chest fur then grew from in-between her newly formed pecs. As her torso bulked up and become masculine, her entire sleeves disintegrate, exposing her exposed muscular arms as her now-sleeveless tight hoodie then shifted into a pair of a dark gray hoodie with a white hood, white and yellow drawstrings, yellow bottom band, and a white print resembling of Sonic's logo in the front to fit her masculine chest and waist as her sports bra vanished from her chest, giving her pecs the need to breathe.

Suddenly, Alan tripped over to the ground, the music stopped, and “Sonic” flew past him. Alan lay there and began to cry. This scene was rather upsetting for Tammy to watch and she kind of tore up myself. But then, “Sonic” appeared right in front of Alan, blood started to come out of his blackened eyes as a grin slowly grew from his face, looking at the unfortunate soul in the body of Tails. Tammy could do nothing but force herself to watch, his final words before his demise were…

“What have you done…?”

Just in a split second, as Alan turned right behind him to see his presence, “Sonic” lunged at Alan and snapped his neck, blood was coming out of his mouth and eyes right before the screen went black, there was the sound of Alan choking to death from off-screen that only lasted 5 seconds. The text returned, only this time it said…

"AW...TOO SLOW. WANT TO TRY AGAIN?"

Tammy was shocked by what happened and said to herself…

“Did Sonic murder Tails? No, he couldn't have… They're supposed to be best friends, right? Why would sonic do that to him?

Tammy shook the shock off as she was brought back to the character select screen. The save file that had “Tails”, or should she say “Alan”, was different; Alan was no-longer in the box itself but in the TV screen, which was flickering with that red static. Tammy was scared by Alan’s expression along with his poorly mangled corpse that was exposed to the skeletal neck and his head’s flesh was half-melted, his orange fur had gone black, and he had an expression of anguish on his face.

Tammy tried to ignore the sight when suddenly, Tammy felt her changed hands and noticed the new gloves along with a ring on her finger she didn't remember having, she then saw how big and muscular her arms have grown as she then flexes the arm muscles and squeezes them while noticing the bandages from her elbows. She then saw her changed hoodie, which was now sleeveless and noticed her changed waist and abdomen along with her torso, noticing how masculine they've gotten as she felt it. Tammy felt flat-chested as she peeked inside her new hoodie to find that her bra was gone and she noticed a new pair of pecks and chest fur. Tammy then felt the soft chest-fur in between her flat-chest as she then placed both of her hands on two of her new pecs. Tammy finds that there were no signs of any reasonably sized lumps of fat in her chest, she moaned a little more in arousal as she caresses and squeezes her pecs.

“Wait a second…that game…it’s turning me into…a man?”

Tammy said to herself, knowing the first changes happening to her. But then she tried to ignore the sight again and selected Knuckles.

The laugh came again as the screen cut to black. It stayed black for 10 seconds, then, another level title came up. It said…

"YOU CAN'T RUN"

Tammy was really freaked out by now, but she couldn't really tell if this was a hack, some kind of sick twisted joke, or some curse…or anything else. But despite her anxiety about what would happen next both game and body, she kept playing. 

The next level looked much different than the last two. It had the ground design of Scrap Brain Zone, but the sky's background looked like the main menu's sky texture, it had a dark reddish cloudy sky. But it was the music that creeped Tammy out the most, it sounded like a vallasite_ogg soundtrack with the same name level title. It was in the dark atmosphere. Tammy made Knuckles move anyway. As he ran down the straight pathway in this dark level, and as he did, it was accompanied by a bolt of lightning.

After a few seconds, Tammy noticed several blood and rusts on the metallic ground. Tammy felt a growing sense of fear, thinking something terrible was gonna happen next to Knuckles. At 1:05 after another lightning bolt, X then floated over Knuckles at one point, right as he started to get weary. He looked afraid just like Tails did, though not as much. Rather he looked a little unnerved, he was looking at her just like Tails was. He did break the fourth wall, just like Tails did, and looked as if he wasn't sure what's going on and was feeling suspicious about her.

“What? Again?”

Said Tammy, not sure if Knuckles was suspecting Tammy to be the killer though she thought she hasn’t done anything to her, but she kept pressing on.

Suddenly, “Sonic” appeared right in front of Knuckles with those black and red eyes. Then, the red static appeared again. When it vanished, it showed nothing but a black screen with a ransom-looking text saying…

"FOUND YOU"

“Okay, what the fuck was going on now?!”

Tammy said with a scared expression on her face.

The red static came again, and then Tammy was back on the level. DAVE looked like he was panicking, as he looked at Tammy again saying…

“Why we you here to torment me all over again?”

“What? I didn’t…Wait, what the hell is happening?”

Tammy said at the state of confusion, as Dave was misunderstanding her as “Sonic” appeared right in front of Dave, but he appeared in pixelated black smoke.

“Was this some kind of boss battle with Sonic?”

Tammy thought to herself as she made Dave punch “Sonic”, but “Sonic” vanished in the black smoke before he could even land a hit. Then, “Sonic” appeared behind Dave, so she made him punch again, and Sonic vanished making mockery poses once more. Dave was panicking more, Tammy felt like she was going crazy too and thought that Sonic was practically playing with them! Some kind of sick twisted little mind game with her and Dave. During the fight in-between Dave and Sonic, the third phases of her changes then applied next…

Tammy felt an uncomfortable pressure happening on her feet as if they were sleeping, the dark blue grew from her feet with dark light tone fur sprouted from under her soles as both of her feet grew. Her toes suddenly merged into sight, paw-like toes with her toenails turning black, growing into toe-claws. Tammy got a cramp from her grown feet; her vans were stretching as if she was outgrowing them. Just then, her vans tore open to expose her grown, masculine paws. As she wiggled each of her toes as she groaned, the pressure applied to her legs the same as her arms, her legs stretched out and grew taller, patches of dark blue and dark light fur started spreading from above the legs as two scars appeared on her ankles. Her legs then bulked up a bit, becoming a manly tone as her spine arched again. Tammy felt a tailbone growing outwards until it fully grew into a dark blue, fuzzy Hedgehog tail, peeking out of her hoodie and pants. Her open vans closed back and were morphed into a pair of dark gray sneakers resembling Sonic’s Grind Shoes from Sonic Adventure 2 as a pair of her tight, pajama bottoms then grew into a pair of black and white striped sweatpants. Her white socks then grew upwards and became a pair of black and white toeless socks that covered the scars on her ankles.

Another cutscene played as Dave fell to his knees as clutched his head, exhausted, Tammy felt his agony as Dave said…

“I…I lost again…I-I’m next…!”

“Next? What do you mean “I’m Next?” It was that “Sonic” who was driving us crazy!”

And then, in a split second, Dave was soon met with a gruesome demise from “Sonic” as Tammy watched the entire death scene in horror.

“Sonic” then kicked Dave on the face, falling back into the ground, and then teleports him, using two fists clutched together to bash him into the chest. The screen wet black with Dave gagging and coughing to death and then screamed in pain that lasted for 5 seconds. Another text message appeared…

"SO MANY SOULS. SO MANY LITTLE TIME. WOULDN'T YOU AGREE?"

“Just what the hell is going on?”

Tammy thought to herself.

“Sonic was trying to talk to me through the game, his friends fear me, and I'm turning into him? It doesn’t make any sense…”

Tammy said to herself at the brink of fear and confusion, as she was bought back to the main menu and this time the second box had “Knuckles”, or should she say “Dave”, on the TV screen. His fur was dark red and his face along with his teeth jagged up. Tammy began to ponder if those were actual characters trapped in those TV screens. However, she couldn't believe it and she didn't want to…

Just as she was about to shut off the game, Tammy's legs felt heavy and saw her new feet and legs. She put her ankle up on her legs and saw the dark blue fur. As Tammy took off her new grip shoe, she saw her newly formed paws as she wiggled her toes and started rubbing one of them while flexing the muscular legs and squeezing them. After putting back her grip shoe on, Tammy thought to herself in realization…

“This can’t be…this REALLY can’t be happening…Part of me was right, not only I’m turning into a Man and an Anthropomorphic Mobian…the game must’ve been turning me into him! That’s why they’re afraid of him!”

Then, she felt a presence behind her as she looked back, and was she saw was the Demon she heard about from earlier…it was a girl with brunette hair, dark magenta steak, pink pair of headphones, black eyes with black liquid seeping out of her eyes, pink sclera, white heart-shaped pupils, pink heart-shaped blushes, black and magenta hoodies with a heart on it, dark magenta demon tail, magenta pair of sport shorts, mis-matched socks, and black and pink heel boots with hearts on the sides. The girl spoke in an accent of Portuguese Danish mix…

“Enjoying the game, Tammy?”

Tammy gasped and saw the pink demon demigirl, named Cherry, with a devious smug on her face.

“Who the hell are you!? And what are you doing in my house?!”

“Oh, nothing much, just watching your gameplay.”

Cherry said as she got down into the room from the windowsill she was chilling as she closed the windows. Tammy, suspecting it was really Cherry being the responsible for the game, began confronting her.

“What the hell did you do this to me?! What have you done to my best friend, Kylie?! And what was THAT in that game she delivered it to me!? Did you even cause all of this?!”

“Oh, all of this?” 

Cherry said as she then told Tammy the entire reasoning, answering her question.

“The reason for EVERYTHING I did. Well, X, or better known as the original Sonic.EXE, eversince he took the lives of both Kyle and Tom, he had retired from terrorizing and tormenting souls a long time ago and has since become a Lord of EXEs and Oddities. Over time, he was getting bored, so Lord X wanted to find the new Sonic.EXE to take his place, the souls he tried choosing was tough…but eventually, Lord X chose you, the one with a major fascination of the Sonic the Hedgehog franchise like I do. Since Lord X read all my stories before, he comes up with a plan without getting your blood in his hands. So, with his request, we worked on a new version of the Sonic.EXE game and cursed that game with the finishing touch. That cursed game has a VOID matter inside that slowly takes over your body in the process in each level you played. That's why you're turning into HIM; YOU are becoming the new Sonic.EXE!”

“W-WHAT?! N-No…That’s impossible! I--”

“Look at yourself and prove it.”

Tammy then does what Cherry says by looking at herself in the bedroom mirror. When she saw her changing body, she realized she’s not only turning into Sonic-look-a-like, but she’s also IN-FACT slowly turning into Sonic.EXE aka 2011 X! Because of that, Tammy screamed in bloody murder at the realization of her changes. Tammy was in a state of panic, not knowing what to do as Cherry laughs devilishly.

“You know, girl, you're a lot of fun to play with X. Just like your friend, Kylie, too bad she lost her femininity and her previous self…”

Cherry said as she smiled gleefully, knowing that it was working successfully on Tammy, who was scared, feeling duped and thinking that this must be a nightmare.

“It won’t be long now until you join her and all of the others who were transformed…”

Tammy saw Cherry walking towards her, as the demon leaned towards her menacingly.

“You can’t go back and resist, girl. Soon, you'll be in his world where Mr. X is at, just like the others who were in their respective, fitting dimensions once they were transformed by body, mind, and soul…”

Cherry said as her eyes glow sinisterly pink, causing Tammy to back up and go back to her computer. Going back to continuing playing the game, Tammy really doesn't know why, but she had to know that it could be all of Cherry's doing. She had to figure out why this was happening. So, she selected Robotnik. However, Tammy still thought that it was odd playing Robotnik.

“Yeah, recently in some games, people played as Robotnik. But in the meantime, let’s cut to the chase!”

Said Cherry as she continues watching Tammy play while waiting for what’s next.

Then, the level title appeared the last time and this time it said…

"..."

“Well, that title looks really freaky.”

Said Tammy prior to starting the level.

“It sure does look freaky.”

Tammy was in a hallway; it didn't really look like it was from any other classic Sonic game. But it did have the 16-bit style. The floor was shiny and checkered; the walls were dark grayish purple with animated candlelight and a few dark bloodstains here and there. There was also a dark red curtain hanging above on the top part of the screen. The music was oddly pleasant, and music to Cherry's ears sounded like a piano playing a rather grim yet peaceful song. But Tammy knew better, this was the song that played in Hill, only it wasn't in reverse.

Robotnik didn't look entirely nervous, like Alan and Dave did, but he did have a suspicious look on his face, as if he was just a bit paranoid. He did a little idle animation where he turns his head to the left, then to the right at least twice, and then shrugs at her. It was as if he had no idea where he was or what was going on. Even though Tammy was scared out of her mind, fearing what was going to happen next to herself and him at the same time, she had Robotnik continue onward.

He did his usual running animation, like at the ending of every classic Sonic game, as she continued through the hallway. Then, Tammy stopped at the long flight of stairs leading downwards. Now, Robotnik seemed unsure of himself. Although Tammy was feeling nervous, she pressed onwards. During that, the third phase of Tammy's changes then occurred as Robotnik looked at her while he ran.

The dark blue and dark light patches of fur then continued from down her masculine waist, her hips cracked, and her thighs receded back into its manly status as she felt her feminine structure becoming more masculine, her sweatpants becoming more fitting.

“Keep going, the more you go deeper down the stairs, the more the transformation keeps going ‘til the end!”
Said Cherry as Robotnik ran down the stairs, Tammy noticed that the walls had gone darker and more reddish, the red torches are now an eerie blue. Then, she landed onto another hallway, this one was longer than the last one, or at least it felt like it. Before long, she reached another flight of stairs. But this one was much longer and took at least 1 full minute. These stairs were so long while she landed into another hallway, the last of her physical changes commenced due to how long the stairs take as Robotnik suspiciously kept watching her transform while running.

Tammy felt an itching but fuzzy feeling on her ears, but she tried to keep going, both of Tammy's ears then grew pointy, the dark blue fur grew on her ears with the dark light on the inside, as they stretched and moved upwards, becoming pointy and Hedgehog-like. The dark blue fur then spread throughout her brown, curly hair, once it's fully spread, her hair grew longer and hardened, baring a striking resemblance of Sonic's quills as both two dark blue spines popped out of her sleeveless hoodie. The dark blue and dark light fur then reached on her face as both two furs grew from two sides of it at the same time. Her eyes bulged and stretched outwards, growing larger and cartoony. Her eyes turned entirely black with red pupils and white irises, glowing. Black liquid started seeping from both out of her eyes and her eyelashes vanished. Her nose then turned black and animalistic, with facial hair like fur growing from below her face and chin, as it started elongating and stretching, becoming animalistic and masculine. During that, her teeth turned yellow and grew sharper. Her face then finally grew into a muzzle of a Masculine Mobian Hedgehog.

“Ooooooooh! Here comes one of my best parts!”

Cherry said as she watched the final, physical change happen as she smirked gleefully. A burning pressure applied on Tammy's groin as the dark blue and dark light fur reached into her hips and her thighs and then between her legs. This burning sensation turned into a little uncomfortable but a little more arousing sensation as she felt her privates pushing out from in-between her legs accompanied by a little uncomfortable but a little arousing squelching sound. She moaned in agonizing but arousing pain and pleasure as this "unknown" area from below kept growing more as her panties become a pair of Sonic-printed undies. Her hormones, along with her sex chromosomes and reproductive system turned inside out, becoming an opposite gender. During Tammy's groaning and moaning, her voice became deeper and sounded sinister, becoming more demonic, as the dark blue fur reached for her neck as it arched, Adam’s apple had completely grown in her throat. Then, the agonizing and arousing pain was over as she panted. Her crotch felt swollen, and it fits for her sweatpants as well, As Tammy felt a grown bulge in her sweatpants with her hand and faced a horrible surprised that she now has a Manhood, meaning that she’s become a man! Not just a man, but an anthropomorphic look-a-like of X! As HE screamed, it was also at this moment that when he covered his mouth, he felt his throat and noticed his newly changed voice as well.

Then, the music ended until it was quiet. As it did, the walls turned dark purple, and the candlelight's flames were gone. When PAUL landed onto the 3rd hallway, Tammy noticed he was now creeped out. Though he tried to hide it, he couldn't blame him, for he was scared too.

“Hmmmm, still afraid yet still feeling pity? Don’t worry, I bought a significant other with me because this time, I’m not alone…”

Cherry said as then suddenly, another demonic but older Sonic-look-a-like with dark blue fur, white tuffs in the ear, earrings, same eyes, blood, and teeth as X's, accompanied by his muscular appearance, more fur, separate sleeved hoodie, black claws, studded bracelets, fingerless gloves, cargo sweatpants, and knee-high boots, popped right in front of Paul the same way the other “Sonic” did with Knuckles!

“Oh, Crimsooooooooon~! He’s almost reaaaaaaaaaady~!”

Cherry called the Demonic Hedgehog’s name in a sing-songy and lovestruck tone just as Crimson turned his snapping neck when he saw her and a fully transformed Tammy, as Crimson then turned to Paul…

“Excuse me for a moment, Doc, I’m doing her a favor.”

Crimson said to Paul as he turned again, the screen turned red static as he came out of the monitor.

“I think I’ll know what’ll do the trick.”

“Perfect! Alright former Human, hold still before I drag you away from here…”

Crimson said as his hand then started glowing red, about to give the mind and mental changing effects.

“N-No…Please…! Anything but--!”

Tammy tried begging and pleading, but it was too late as Crimson shoved a glowing hand on Tammy’s head, grabbing her with force. Using his powers, Crimson was removing Tammy's memories as a Human Girl as his mind started fuzzing out, he gets down to his knees as he trembled, saliva was drooling out of his muzzle, his protests and pleads were fading.

His mind and personality both changed in the process, he went from an energetic but smart Sonic fangirl into a sadistic and cruel monster that possesses an instinctive lust for destruction and pain. He now has an immense interest in Humans and the Sonic the Hedgehog franchise, taking away the souls of people and putting them into the bodies of said franchises’ characters, seeing the Humans as disposable puppets that he can manipulate and torture for as long as he likes simply because he wields the power to do so. Having an interest in playing games that serves as entertainment for his sadism and is also being extremely short-tempered. When something is not played in his favor, he can often become uncharacteristically impatient or angry. He then started to grow to remember, being in a vessel of a Hedgehog, wearing his disguise to lure his victims, and having four of his victims as his playthings he'd love to torment.

During the mind-changing process as his resistance and protests were gone, Crimson dragged the former Human away as Cherry comes to follow the two.

Inside the game, Paul watched in fear as the former Human-turned-VOID Matter Hedgehog finally appeared in front of him, who was teleported there by Cherry and Crimson from behind. Paul gasped and said…

“W-What?! Y-You again!?”

As Paul watched as the former Human then started twitching, Crimson was almost putting on the finishing touches on his changing mind and said…

“Give in, Tammy…or should I say X. And repeat after me…YOU ARE GOD.”

As Crimson was finished using his abilities on his head, “X” was fully giving as Paul was forced to watch, knowing that this is about to happen again…

“I…I…I am…I…I…I am…I am…I am…”

As the couple backed away, the former Human the slowly twitched as he rises from the ground, remembering who he is and forgotten his past as a Human named “Tammy”, he was now X…also known as Sonic.EXE and 2011 X. X finally smiled menacingly, his eyes flashed open and finally said his well-known line…

“…I AM GOD!”

…And then, he lets out his Kefka-esque laughter as Paul’s shades dropped in fear as he sweated.

“Congratulations, you’ve become the new Sonic.EXE. And now that we’re so kind, we’ll leave you two to catch on. Have fun killing and stealing Human souls, X!”

Cherry said as she, along with Crimson, both left the game and returned to their world, leaving Paul with the new X in front of him, knowing he’s about to suffer the same fate as Alan and Dave.

X's jaws and mouth stretched outwards, opened widely as Paul was about to once again suffer his gruesome fate. The red static lasted for about 15 seconds…

Suddenly, X had realized that he was now in Lord X's place since his retirement from taking the lives of Humanity, and now that he's become the next Sonic.EXE (with all thanks to two shapeshifting demons), he feels like he's starting to follow his footsteps, and has done to three victims he grew to remember. He rose up again, his grin growing wide a demonic as his eyes flashed and widened open as if he was staring RIGHT AT THE PLAYER. X lets out his demonic and distorted Kefka-esque laugh, as he finally said to himself...

“Yes, this is who I finally am…I am X…and I. AM. GOD!”

As he laughed, just then, another unfortunate player then started his game, knowing that he had found another victim. he is ready to put on his disguise to lure the victim and take away their soul again, and soon, X is ready to kill and torment just like what Lord X used to do.

READY FOR ROUND 2?
