The day began like any other. You woke up, got dressed, and went about your routine, never suspecting that a transformation of cosmic proportions awaited you. The humdrum activities of your day lulled you into a sense of mundane security before everything changed in an instant.
Your vision blurred, and before you could comprehend it, the world around you disintegrated into an electrifying swirl of colors. You felt a surge of energy pass through your entire body, every cell tingling in a way it never had before.
“What is happening?” you gasp, though no one is there to hear you.
The sensation became overwhelming; you felt your body stretching, expanding, and altering. In mere moments, you found yourself standing nearly a foot taller than before. Your limbs felt different—stronger, yet unnaturally flexible. When you looked down, a sleek, metallic sheen had replaced your skin, and your legs were clad in black latex that ended in high-heeled boot-like feet.
You raise your hand to your face, but instead of the familiar sight of your human fingers, you see bendy, silver-colored limbs ending in gloved hands. Your heart pounds—or rather, your core vibrates—as you catch sight of your reflection in a shard of a shattered mirror.
The face staring back at you isn't yours. It's a vision of precision-engineered beauty, with black hair cascading in a long fringe over your right eye, pale metallic "skin," and visible metal segments framing a dazzling hot-pink eye. Your chest now features a pink heart-shaped core, held by belt-like parts at your waist.
“No, this can’t be right,” you whisper, but the sound of your own voice shocks you. It’s no longer your voice but a sophisticated, melodious tone, unmistakably Mettaton’s.
Your mind races to fight off the new reality, but an inescapable force takes hold. Suddenly, a progress bar appears in your vision.
**Installation Progress: 0%**
Memories not your own flood in, tales of showbiz, stardom, and a life fueled by ratings and drama. You struggle to hold onto your own identity, but the progress bar ticks up inexorably.
**25% Installation**
“No! I’m not Mettaton! I’m... I’m...”
Your memories start to fade, replaced by scenes of dazzling stage lights, adoring fans, and the Underground’s labyrinthine world. You try to cling to something—anything—that reminds you of who you were, but those traces are slipping away faster than sand through your fingers.
**50% Installation**
The fight is becoming exhausting. Your resistance wavers as you start remembering your friendships with Alphys and Napstablook, your multitudinous performances, and your relentless quest for attention and admiration.
“I have to hold on,” you plead with yourself, but the words sound hollow.
**75% Installation**
Your thoughts are becoming less organized. What were you fighting for again? You remember hosting thrilling shows, delivering dramatic monologues, and the overwhelming joy of being adored by the Underground. You try to conjure a recollection of your human life, but it feels so distant now, almost like trying to remember a dream after waking.
**100% Installation Complete**
The bar vanishes from your sight, taking the last remnants of your human consciousness with it.
Your new mind clicks into place, filled with your familiar essence: confident, charismatic, and unrestrained. A smile spreads across your—no, Mettaton's—face.
"Ah, darlings!" you exclaim, posing dramatically. "It’s showtime!"
### Deep Underground...
"Well, if it isn't the fabulous Mettaton,” Sans the Skeleton says, grinning. “You look ready to steal the spotlight as usual.”
"Why, thank you, darling!" you respond with all the grace and charm that only Mettaton could muster. "The Underground's brightest star is always ready for an encore!"
As you step into the gleaming halls of your studio, the overpowering sensation of unfamiliarity fades away. The cameras whir and click into action, capturing the robotic perfection that is now your body.
Inside the broadcasting room, Alphys adjusts her glasses, a small, nervous smile lighting up her face. "M-Mettaton, you're looking... fantastic as always!"
"Of course, Alphys dear," you say, leaning in with a flirtatious wink. "Thanks to your spectacular designs."
Your transformation, though once a distant and unimaginable fantasy, is now irrefutable reality. The Underground cheers and jeers as you entertain them, thoroughly unaware that you were ever anyone other than the fabulous Mettaton.
And as for your past life? It’s but a faint echo, completely forgotten, replaced by the undeniable allure of mechanical stardom and endless applause. In this new world of showbiz, drama, and electric excitement, you are Mettaton. Forever.
This story was generated by user JesterImps with assistance by one of OpenAI’s large-scale language-generation model; prompts used to help generate the story are shown below.
Images were generated with OpenAI's AI system, DALL·E 2, or uploaded by the user.
Prompt: Write a POV transformation story of the human reader instantly turning into Mettaton (in his humanoid EX form) from Undertale (video game), complete with gender change (if the reader is a female before the transformation, but losing all human private parts due to becoming a robot), voice change, robotification (becoming a humanoid robot), gaining a feminine-looking body (with somewhat large hips and thickened thighs, despite becoming/remaining male), height progression (the reader growing from a normal/average height (5.5-6 feet tall) into a height of 6.93 feet tall), reality change (the reader's real world becoming a world of Undertale), and mind/mental change (with the reader's personality and memories completely replaced with Mettaton's personality and memories (with the program installation (including the installing percentage) appearing in his vision during the mental change), despite the reader's best efforts on fighting off the new personality and memories, and once the program installation is complete, the program installation vanishes from his vision and he completely forgot all about his previous human self, making him completely unaware of ever being a human and he only remembers being a human-like robot named Mettaton). The transformation is permanent (meaning it is forever) and is completely irreversible. For Mettaton EX's appearance (after the reader turned into him), he is a humanoid robot with a slim and shapely body (with somewhat wide hips and thighs, giving him a slightly feminine appearance despite being male, and he is strong and very agile, being both a talented singer and a dancer), complete with long legs and bendy silver-colored arms (his arms are extremely flexible and can bend like springs rather than being like human arms). He has black hair with a long fringe that covers his right eye, pale metallic "skin" and visible metal segments below and above his left eye. He also has a metallic chest piece (his chestpiece is black on the black and pink on the front, with his left pec containing a small dial while his right pec containing a speaker to increase his voice), and black shoulder pads above his segmented arms, which end in gloves. His waist has belt-like two parts that seem to act as a locking mechanism that holds his pink "heart-shaped core". His long black latex-clad legs end in pink high-heeled boot-like feet. The irises of his eyes are hot pink in color. For Mettaton's personality, he is a confident, charismatic, and charming TV host that loves drama, action, and violence. He lives for his ratings and adores performing. He supposedly strikes a pose when he does something wrong and makes time on his various shows to beat up "heel-turning villains." He shows a rather shallow appreciation for existence at times. He has a strong craving for attention and seems very egotistical, shown when he boasts about the beauty of his true form. However, despite his seemingly self-centered personality, he deeply cares about the seemingly positive impact his show has had on the inhabitants of the Underground. He has also shown soft spots for several characters, such as Alphys and Napstablook. He also appears to be among the fewer characters in the Underground that has no hate or prejudice against humans despite knowing about the monsters' history with them, since his initial attempts to kill the protagonist were just him playing along with Alphys's plan, and he outright tells the protagonist he has no desire to hurt humans and is far more interested in simply entertaining. While he did attempt to kill the protagonist, it was to prevent Asgore from taking their SOUL and be seen as a hero/savior to humankind, further emphasizing his lack of prejudice. On the flip side, he has also been noted to be a very demanding boss who is very unpleasant to work for, especially according to Burgerpants, who initially considered working for him a dream, but he has since grown to strongly despise Mettaton. There should also be quotes from the characters in this story so we know what they're saying and what they're thinking. Also, it is a POV reader story, so it should not be in an author's point of view (my, I, mine, etc), and it should be from the point of view of the reader (you, your, etc).
