Chelsea was a huge fan of Sonic the Hedgehog franchise, her favorite character from the game was Knuckles the Echidna. Chelsea relates to Knuckles a lot because of his brawn skills, the red colors, and how not only he defends the Emeralds, but his friends too, not to mention, her favorite game when she was a kid was Knuckles Chaotix. All Chelsea wanted to do, like Knuckles, was to protect those she cared for, including her friends. She wishes she could also let them stand up for themselves.

One day, Chelsea had grabbed a game from the attic, Knuckles Chaotix, for the SEGA 32X and inserted it into her old console, to reminisce her childhood days. She was wondering what happened to her friends, even her old friend, Cora, whom she hadn’t even seen in a month. Chelsea was one of Cora's friends she got who was helping her journey to transition, helping with her communication issues, and accepted her as a Transgender Man, while trying her best to deal with her bullies. She had to play her worries away, though still cared deeply about her friends like her especially when she used to play Knuckles Chaotix with them through playtime. But what she didn't notice was that she was being watched by a surveillance cam nearby, as a blue-haired woman with glasses was watching over her…

“Well, well, well. You’ve done it again, Sapphire, you done it again.”

Sapphire gloated to herself as picks up a USB Flash Drive with the word “CHAOTIX” written in sharpie on the masking tape labeled in the front.

“With this bug that only works on Mega Drives, let’s start phase one by plugging this baby in and see what happens.”

Sapphire said as she then inserted the usb flash drive in her computer hardware, as the Mega Drive-exclusive virus was ready to send. The message on the computer said…

"Are you sure you wanted to transfer "CHAOTIX.32X" to Chelsea's 32X?"

Sapphire smirked, knowing this was finally going to happen on a victim she’s spying on, as she clicked on yes, the virus is transferred from her hard drive, blue sparks flying from the inside of her cord.

“Go, my little virus. First, corrupt that console, and then Chelsea herself…”

Sapphire said as she chuckled deviously, preparing for phase one…

Meanwhile, Chelsea was in the middle of playing Isolated Island, just as she was about to complete the level, the game started to corrupt in a matter of seconds.

“Huh?? What the hell??”

Chelsea flinched in shock as she then reached for the Mega Drive and the 32X to see if it overheated…however, just as she was about to check on it. A powerful surge resulted in the Mega Drive and 32X dragging in Chelsea as she tried to run…but to no avail, as Chelsea gets sucked inside of the console.

A few moments later after this happened, Chelsea then woke up the inside of the console, the Isolated Island level that she was playing.

“Huh…Wuh…Where am I??”

Chelsea said to herself as she got up from being blacked out on the ground, as she then takes the look at the entire Isolated Island, it felt so real-looking…just like the game.

“Did that console sent me here inside the Game??”

Chelsea said to herself as she started to investigate through the Isolated Island while in the game, as she started thinking about finding a way out while wondering about her old friend that she would be looking for. Meanwhile again, Sapphire was surveilling the game with Chelsea investigating the inside of it, as she lets out a smirk.

“And now…for phase 2.”

Sapphire said to herself as she uses her hacking skills to manifest two corrupted amalgamated codes resembling of an Echidna and a Fox as the two conjoined codes then located to where Chelsea was at.

“There she is. Fly my little code, and overtake her, soon, this will be your new body and once you’ll take over hers, you’ll change her by body, mind, and soul into what truly fits you as a glitched Fox and Echidna hybrid. See you after the possession, little code~”

Sapphire giggled as the code then flies into the Knuckles Chaotix, looking for Chelsea anywhere…upon finding her location where she was trying to search for her old friend while investigating the island. The code spoke…

“TARGET SPOTTED!”

“Huh?? Do I hear…noises??”

Chelsea said in a surprised tone of voice as she felt a corrupted presence behind her. When she turned back, the fox-echidna amalgamated code then sprints closer to Chelsea and went inside her body.

“AGH!! W-What the hell!?”

Chelsea shouted as she jolted. Just then in a matter of seconds, Chelsea then felt a shock in her body as she clutched her stomach in pain.

“Ooooooh! What’s going on??”

Chelsea groaned in pain, feeling a transformation about to start.

Chelsea first felt the black hex-pattern-like engravings form all over her tingling hands as they started growing and becoming masculine, her fingers grow into sharp claws. The engravings then spread from her wrists while the gray fur spread to her arms, the hex-pattern-like engravings then formed on both of her shoulders. Her arms elongate outwardly as they bulk up into a masculine frame. Both yellow and red gloves with code engravings on the tips then manifested on her masculine hands, her shoulders broadened as the gray fur sprouted all over to her waistline as her height grew a bit taller, her spine arched to its masculine state. The gray fur along with the hex engravings then reached her torso slowly as her hips and waist then broadened to its mannish frame. Chelsea felt a tingling sensation from her chest, as gray and hex-engraved chest fur then grew outwards, her breasts then become flattened and hardened into masculine pectorals. Her shirt and bra were dissipated to expose her Mobian-esque pecs and waist.

The pressure then applied to Chelsea's feet, once the gray and hex-engraved patches of fur formed on them, her feet then grew bigger with her toes becoming six and paw-like. Her toenails become black claws. Chelsea's shoes and socks teared out to reveal her masculine paws, her legs stretched outwards, becoming taller with them bulking up a bit as the fur and engravings spread from her legs to above her thighs. A gray and hex-like-engraving fox and echidna-hybrid tail grew out, but it didn't grow outwards slowly a bit, it just immediately popped out. As Chelsea felt her new, fuzzy tail, her shoes closed back and shifted into a pair of red shoes with green cuffs and gray soles with black engravings on them.

Chelsea's ears then grew pointy, gray patches of fur along with hex-pattern-like engravings formed on them as they moved upwards, becoming a pair of fox ears, the gray fur and code engravings spread throughout her red hair as they grew longer, becoming spines resembling of Knuckles the Echidna's with two hairlocks resembling of Miles “Tails” Prower’s.

“Hey, wait a minute, WHAT THE FU--?!”

Chelsea said in a shock just as her line was suddenly interrupted by the gray fur forming on her face and whiskers growing from two sides. The hex engravings formed from her eyes as her entire blue eyes turned entirely red with her pupils becoming entirely black, though it remained in shape since she was already diagnosed with polycoria. Her nose turned entirely black as her face elongates. During that, her mouth turned entirely black with her teeth turned entirely red and exposed with engravings forming from her lips and mouth. Chelsea's face finally grew into the muzzle of a Masculine Mobian Echidna.

The gray fur then reached into her hips, thighs, and in between her legs, Chelsea's hips and thighs receded as her feminine structure turned masculine. Chelsea's crotch, along with her chromosomes, reproductive system, and hormones were shifted into the opposite gender, rendered her as him. The gray fur reached for his neck as it arched, with an Adam’s apple forming from the inside of his throat, giving him a deep, masculine, but glitched, distorted, and corrupt tone of voice. His pants and panties were dissipated the same as his former top, exposing the lower part of his fur.

Chelsea's painful transformation was over physically, but not fully done yet... Chelsea's mind was corrupted and fuzzing out, his mind and personality were reprogramming from a tough-as-nails girls who is protective of those she cared for and wishes that she could let them stand up for themselves to nothing but broken remnants of leftover codes meant for Tails from the prototype version of Knuckles' Chaotix called "Sonic Crackers". Having been abandoned in the game for years, he desperately searches for the other leftover remnants of Tails to become whole once more and fix himself, not realizing that he himself is Knuckles fused together with Tails by a horrible glitch and the other remnant doesn't exist. He's no-longer Chelsea anymore...but Chaotix.

“MUST…FIND…TAILS’ CODE!!”

Chaotix said in his new tone of his masculine, glitched voice, surrounded by Glitch effects as he runs wild throughout the Isolated Island to continue to search for what remains of Tails code…

“My work here is done!”

Sapphire, who watched the entire transformation the whole time, said as she gave herself a rest on her chair.

 “Have fun glitching around, Chaotix!”


***

Time has passed since Chaotix has forgotten his past as a Human female, but he almost forgot about something, and it was an old friend of his. While searching for the Remnants of Tails’s code, he noticed a presence in front of him at the Isolated Island.

“I’m…I’m so lost…Where is everybody…?”

A masculine tone of voice said in desperation as Chaotix started to recognize that familiar voice but a changed appearance, resembling of a Transmasc Mobian Hedgehog with a curse…as Chaotix went closer, he saw those tears and that smile, he begin to remember someone…he was best friends with a Dimension Traveling and kindhearted EXE who was a fugitive in the past and spend time with eachother often…It was Curse! He also recognized the last time he saw his forgotten previous self once called “Cora” in about a month prior to his changes body, mind, and soul into what he currently is. If Chaotix and Curse were friends who were once Humans in the past going through the same problems eachother before their changes twice then that means—


“G-GAAAAAH!! W-WHO’S THERE?! S-SHOW YOURSELF!!”

Curse flinched in terror when he saw a glitched presence right behind him as he takes out his time eater scythe, only for him to recognize an old bestie of his.

“W-Wait, C-Chaotix??”

Curse said as Chaotix then started growing passive, His height lengthened down and decreasing, his fur and dreads turned red with some code-pattern engravings and fluff-like balls on the bottom of them, there weren't any more code engravings on his body, except for the sides. He now only has one eye that is a scribble circle and now has an exposed chest-fur. His gloves are now white with a belt-buckle-like strap, red shoes with white cuffs, white soles, and belt buckles. His ears are down, and his tail got a little smaller and red. His face becomes a peach-tone. He was turned into his Faker form, that looked like Knuckles, growing docile and passive when he saw his best friend. 

“No way…It’s you. But how?”

Said Chaotix while in his normal, masculine tone of voice as Curse tells his best friend of what happened.

“Remember that you used to help my journey to my transition, help me with my communication problems, and accept me as a Transgender Man when we were Human. Well, now thanks to my new wardrobe that gave me a new look and a new body, I have finally found myself but now I fully remember that I was Curse, now I have forgotten my past as a Human. As I traveled through dimensions, I've been trying my best to communicate properly and have my fellow EXEs and Oddities accept me of who I am... but as a month passed, I have gotten a bit lonely and wondered if you've been worried about me lately...which made me grow to miss you. But now when I saw you and your newfound form, I've realized something...I recognized the best friend I remembered, and that best friend of yours was you, Chaotix.”

“You mean…you remembered me as a best friend since we’ve forgotten our past selves??”

“Yeah, it’s really you…!”

Curse then tearfully hugged the Echidna-Tails hybrid glitch in an embrace, tar-like tears flow down on Chaotix’s shoulders as he hugged him back in a warm embrace.

“And you know what? It’s nice to see you back again, Chaotix.”

“It sure is too, Curse.”

“But wait! I didn’t even know who that nice, blue-haired girl is, the one who knows of hacking technology including game consoles. She was an acquaintance of mine when I saw her the last time.”

“…You met Sapphire too? Well, not only is she skilled in tech and knows others’ information, but she likes glitched entities and bought me back.”

“Wait, Sapphire? She’s the one who bought you back?”

“Of course, and I’m sure you’ll get to know her outside of the game. She wasn’t home right now, once she’ll return at 8:00 PM. I believe you’ll visit her, and she’ll be your new friend.”

“Okay, Chaotix!”

Curse joyfully said as he started to spend more time closely with his best friend, Chaotix as they waited until the blue hacker gets back. The two best friends were glad to see each other again after one month apart.

“So, Chaotix, can you tell me more about Sapphire?”

“You’ll see when she gets back, now, where were we at the Isolated Island here in my game?”
