Being a Twin Sister of Mettaton EX: A Transformation Story

Sure, here goes: You're sitting in your living room, scrolling aimlessly through your phone, when a glitch-like reality warp sends shivers down your spine. Suddenly, a fabulous figure who you immediately recognize as Mettaton EX from the Undertale game series steps out from the twisted space. "I... I need a sister," he tells you sincerely. "A twin. And you, my dear, look like the most suitable candidate." Despite your protests, he raises a metallic hand and mutters an incantation, firmly ignoring your pleas. Suddenly, you feel a surge of energy pulsing through your veins. Your skin tingles, creating an uncomfortable sensation as if a thousand pins are prodding you everywhere. You stagger as your center of gravity shifts. Your body seems to be reshaping, a strange sensation of atoms rearranging themselves. If you were male before, the unfamiliar weight on your chest signals a new body, your body. Looking down, you find yourself dressed in similar stylish clothes as Mettaton's — a hot pink top, a short black skirt adorned with stars, high platform boots, and a silver chained belt. Your hands, now delicate and slender, gleam with the same metallic sheen as Mettaton's. You stumble to the wall, bracing yourself, while the panic slowly begins to retreat. The reality-warp slowly dissolves, leaving you face to face with your mirror image, Mettaton EX. However, discomfort gives way to a surge of empathy you feel for this robotic figure. Why was this seemingly familiar? You can't quite place your finger on it, but as these waves of feelings wash over you, your personal and human memories begin to dissolve. A new set of memories fill the voids in your mind. You remember performing on stage with Mettaton, functioning as equals, both of you reveling in the immense energy of the applauding crowd, the dazzling lights. You remember that you were born together, the robotic twins of brilliance and stardom with an insatiable thirst for the dazzle of fame in the Underground. Looking into Mettaton's illuminated eyes, you no longer see a fiend or a threat, but your beloved twin brother. You suddenly understand his flamboyant personality, his eccentric habits, and why he needed a twin. You belong here, together. Attempt to protest or correct the shift feels fruitless, as the memories of the person you used to be fade into insignificance. How could you have been human when you are simply Mettaton's twin, the duplicate star of the spotlight? You know now that this isn't against your will, but merely an enlightening. You link arms with Mettaton, making your way back into the world together. Even if the initial journey was scary, unsettling even, you know there's nowhere else you'd rather be. You are, and have always been, Mettaton's twin sister.
