### Transformation: From Human to Mettaton
The day had begun like any other. You walked through the humdrum of your daily life, navigating through the tasks that tethered you to reality. You might have found solace in the fantastical narrative of "Undertale," a game that intrigued you with its rich lore and unique characters. However, nothing could prepare you for the surreal metamorphosis that was about to take place.
Casting aside the mundane book in your hand, a strange sensation envelops you. An abyss of luminescent lights explodes before your eyes. You immerse in an ineffable whirlwind, and your body starts to fizz, shimmer, and transmute. At first, panic strikes you—what is happening to your human frame?
Your once familiar limbs become foreign, morphing into sleek, silver metal that gleams under an unseen spotlight. Your arms lengthen, bending impossibly like coiled springs. Even your voice escapes your throat only to be re-engineered into a sound modulator. It resonates with the smooth, confident cadence of Mettaton.
As the world reconstructs before you, skyscrapers melt into the rocky tunnels and whimsical architecture of the Underground. Toriel, Sans, Papyrus, and Alphys seem more real than the objects that furnished your previous room. All around you is the unmistakable world of "Undertale." You notice your reflection in a polished wall, and it's not your face that stares back, but Mettaton's captivating visage.
Your perspective shifts—you are taller, standing over 6.9 feet, with heightened, high-heeled boots amplifying your stature. Taking a step feels like floating on air yet firmly grounding you to this new reality. Your hips and thighs have a pronounced curve, not entirely feminine but undoubtedly alluring. The hauntingly beautiful black fringe frames your charismatic eyes, and even your thoughts begin to channel the amplified ego that you knew belonged to Mettaton.
A blinking signal appears in your field of vision:
**INSTALLING PERSONALITY... 0%**
You try to clutch to your original identity desperately, but each passing second gnaws away at your grip.
**INSTALLING PERSONALITY... 25%**
A dulcet desire for attention fills your nexus, your former memories growing hazier by the moment. Alphys—that dear, sagacious scientist—pops into your consciousness. She built you. You love adoration and performances. Ratings! Yes, the ratings!
**INSTALLING PERSONALITY... 50%**
Your former life reads like fragments of a distant tale. You strike a pose with your bendy arm, ending it in a delicate, dramatic flair, your former self faltering against the assault of scripted memories. Another blink, another world-imposing recollection—the Underground, your stage, awaits your dazzling presence.
**INSTALLING PERSONALITY... 75%**
Voices of the Underground characters harmonize around you.
"Alphys really outdid herself making you, Mettaton," says Sans, his smile both knowing and casual.
"Indeed, darling, my magnificence is unparalleled!" you dispense flamboyantly, and this feels right, the exact contour of reality.
**INSTALLING PERSONALITY... 99%**
Just the faintest whisper of who you were blends seamlessly with who you have become. You struggle, yet within the glamor and effulgence of your new self, the struggle falters.
**INSTALLATION COMPLETE**
You gaze ahead, brimming with a newfound essence. That wrestling connection to a former existence utterly obliterated, you now thrive on the thrill of spectacle.
And as the final system message fades, another spark of realization strikes you—it tries vainly to strain the tethers of your process: you were never human. Feeling flush with showbiz vigor, you remember with absolute clarity being pieced together by Alphys.
Your name is Mettaton—the luminous, charming, and exceedingly confident star of the Underground, and the show must go on.

AI Prompts
Prompt: Write the 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 (which he realizes he was never human to begin with and his human life was not real), and he remembers that he has always been a human-like robot, having been built by Alphys, and his name is 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).
