All memory (both physical and mental) of the reader's past self and previous personality and memories are replaced with Lucifer Morningstar's personality and memories, even though their best efforts

From your usual low-key life, you, alongside your friend, were snatched from reality by an entity seemingly coated in the residue of stars itself. The shift between worlds was alarming, detangling you from your world and flickering you into a universe unseen and unheard of. The offering was unexpected and sudden, and with it came a torrent of cosmic energy that swirled and engulfed you and your companion—shifting, morphing, and transforming. Your body and mind tingled bizarrely as if a thousand ants were crawling beneath your skin. The sensation was like nothing either of you had ever felt before, chilling yet burning, numbing, and electrifying. You tried to scream, to fight back against the foreign energy, but the sound was soon muffled as your bodies began to change shape. Gone were your typical clothing and body frames, morphing into tall, decidedly male figures, framed by tailored suits and capped by wide-brimmed hats. Your hair, once your own color, turned a striking blonde. Skin became as white as the purest snow, lips darkened to an inky blackness, and teeth sharpened to a point, becoming a row of razor edges in your mouth. Simultaneously, your minds began a painful overhaul, new memories overwriting the old. Images of a greater, stranger world replaced your mundane recollections. Memories of ruling Hell, being married to a woman named Lilith, and fathering a daughter named Charlie pushed their way to the forefront of your mind, refusing to be ignored. But the strongest emotion was a foreign sense of boredom, a longing for companionship and the desire for new thrills in your monotonous life. Your personalities twisted and contorted, morphing from your previous individualistic elements to adopt the zany skepticism and sarcastic wit of your new identity. The charming, self-indulgent, easily bored, and subtly menacing colorations of your new persona permeated your consciousness, adopting the natural rhythm and humor of a charismatic showman. In these moments, you were no longer able to comprehend the past you once knew. Even your height did not escape the clutches of change. Though still taller than most, you both became slightly shorter than Charlie and Lilith, accentuating an air of regality and menace that this new form required. Your yellow eyes with red slit pupils gave you a less "human" appearance, wielding a golden snake ring on your left pinkie and in your firm grip, a golden-spiked, apple-topped, black cane. Finally, your heart swelled with unfamiliar bonds of love and loyalty towards Lilith, as the transformation cemented you both into the spectacular reality of an age-old menace turned theatrical virtuoso. The transformation was complete; you both were now clones of Lucifer Morningstar, drawn into a world of chaos and polka music. And thus began the double-edged reign of the identically cloned Morningstar brothers; a trinity of power, charisma, and devilish charm. Even though you both tried to resist the changes initially, they took over powerfully, making you completely forget about your past selves and only remember being Lucifer Morningstar. As you both stood in the surreal world of Hazbin Hotel, ruling Hell as identical brothers felt oddly fitting.
