Charlie Transformation: Embracing the Prince of Hell

Prompt: Write a transformation story of a male human reader turning into a genderbended version of Charlie Morningstar (from the alternate version of the adults cartoon/animated series Hazbin Hotel), complete with instant clothes change, height change, age change, reality change (with the reader's real world warping and turning into an alternate world of the Hazbin Hotel series (without the canonical female Charlie Morningstar existing in that alternate world and having the reader as that world's male replacement)), and mind/mental change (with the reader's personality and memories being completely replaced by male Charlie Morningstar's personality and memories, despite the reader's best efforts on fighting off his mind/mental changes and his fears of losing/forgetting himself, making him completely forget that he was ever human and entirely forgetting about everything that had happened moments ago, knowing it to be a strange daydream (he knows that he was born to Lucifer Morningstar and Lilith Morningstar as a humanoid hellborn demon, so being human was impossible and he knows that he was never human to begin with), and he remembers that he was and always had been a hellborn demon, a prince of Hell, a son of Lucifer Morningstar and Lilith, and his name had always been Charlie Morningstar). The transformation is permanent (meaning it is forever) and is completely irreversible. For the male Charlie Morningstar's appearance (after the reader turned into him), he is a tall and slim-built white-skinned hellborn demon, standing at over 6 foot, around 6 and a half feet tall. He has medium-length blonde hair with thin light coral streaks on the paler-blonde highlights, which is slicked back neatly sport light yellow sclera and red pupils, and have black eyelashes and gray eyelids. He has thin black lips and rosy red cheeks, which resembles those of dolls and marionettes. He also has animal-like traits, such as red-toed cloven hooves, fangs (instead of regular canine teeth) in his mouth, and a small, yet noticeable black animal-like nose. His fingernails are black and pointed. Like the canonical Charlie Morningstar (who is female), Charlie Morningstar (who is male) of this alternate universe wears a red tuxedo-jacket with darker red lapels and a small white tag located on the left side. He wears this over an untucked, long-sleeved, high-collared white dress-shirt that has two black buttons and dark red cuffs, worn with black suspenders and a small black bowtie. His dress pants are colored in a slight darker shade than his jacket, and his footwear (which he wears over his hoofed feet) are heeled, white saddle shoes with black toes and tips of the heels. When in his full demon form, a pair of dark maroon horns protrude from his head, and his eyes change to have red sclera with white irises and slit pupils; thin black streaks also appear across each eye. His eyelashes become much longer and thicker, resembling butterfly wings. His fingers turn mostly black and become sharp and claw-like. He also gains a long black demonic tail with spikes and a triangular tip with a red heart on the center. In order to block Adam's punch, Charlie's arm became large, dark red and demonic with light red markings and longer black fingers. Here are the male Charlie Morningstar's abilities/powers; he has immortality (as demonic royalty, and as mentioned by Adam in "The Show Must Go On", Charlie is biologically immortal, presumably being able to live for a long period of time and only able to be killed by angelic weaponry), demon transformation (as mentioned, Charlie can enter a fearsome, more powerful Demon form), demonic arm (in the episode "The Show Must Go On", Charlie's arm became large and demonic, and with it he blocked Adam's punch with ease), pyrokinesis (Charlie is able to summon fire at will, shown able to erupt flames from the ground, which become a fiery tornado around himself when transforming into his full demon form. He also set Tom Trench on fire (albeit offscreen) during his brawl at 666 News), pyrotechnic generation (the pyrotechnics shown during I'm Always Chasing Rainbows were summoned from the palm of Charlie's hand. She later produced them from her finger against the Exorcists in the episode "The Show Must Go On"), glitter generation (Charlie is able to generate glitter from her hands, which she threw at an Exorcist in the episode "The Show Must Go On"), demonic magic (being the son of Lucifer, Charlie can access powerful magic that is exclusive to the higher-ranking demons), sorcery (in the Finale of the episode "The Show Must Go On", Charlie cast a sparkly golden magic which lit up a row of newly installed lights), and conjuration (Charlie can summon objects out of thin air, such as his Hazbin Hotel drawings he showed to Adam, before Adam interrupted him. He also summoned a pitchfork in the episode "The Show Must Go On" after transforming into his full demon form). He also has his own shield (which is an intricately designed shield which Charlie used in the episode "The Show Must Go On". Its design appears themed after Lucifer, being in the shape of an apple colored in red, and having a golden snake in the middle with six golden wings) and a pitchfork (which Charlie conjured after transforming into his full demon form. Its design appears themed after Lucifer, with a golden snake wrapped down the length of it and a red apple at the top) used as defenses and weapons. He also has the following skillsets; multilingualism (Charlie speaks fluent English and is said to also be able to fluently speak the Demonic languages he grew up learning), hand-to-hand combat (As demonstrated in the Hazbin Hotel pilot, Charlie is able to hold his own when in hand-to-hand fighting. He did not hesitate to engage in a round of fisticuffs with antagonistic news caster Katie Killjoy), musical talent (Charlie is considered a very talented singer, even outside of the show's non-diegetic musical numbers. He can also play the piano), and dancing (in addition to his musical abilities, Charlie is also a skilled dancer and a fast-learner, as shown in Alastor's Reprise, wherein he dances perfectly in sync to Alastor's steps. Charlie's personal style of dance is tap-dancing, something he can do very well). For Charlie's personality, he is compassionate and empathetic to a fault, feeling genuinely upset at the idea of harm coming to others. Although he isn't unaware that Hell is populated with souls that have committed egregious acts in their living lives, he still views their yearly extermination as a senseless waste and makes it his personal mission to help them avoid it via self-betterment and eventual redemption, something he is seemingly alone in believing is possible.Charlie's idealism, while setting him apart from many of his hellborn peers, can also make his naïve to many of the harsh realities that appear to stand in the way of his potential success - something his girlfriend, Vaggie, tries to remind him of, only to be cheerfully ignored in favor of a more blinkered, sunny optimism. This can also cause him to rush headlong into the initial stages of his plans without much preparation (his prompt list before his big news appearance reading only "unicorn kisses, dolphin high fives, sing showtunes = happy ending?"). Charlie has a love for musical theatre, song and dance, and will often convey his emotions and ideas through showtunes and ballads. He appears to take perceived failures hard, as he believes his heartfelt theatrical passion should be enough to bring people over to his way of thinking, and is disheartened when it's not as simple as he imagines. He openly admits during a dejected voicemail to his mother (Lilith) that he doesn't actually know what he is doing, or how to make his plan for reforming sinners work in practice. Despite being sweet and lacking "street-smarts", this doesn't make Charlie a pushover or stupid. When people insult him or openly mock his ideals and plans, he has no hesitation in standing up for himself, or even rolling up his sleeves to physically fight back. Swearing is also something that's generally not part of his vocabulary and he doesn't cuss all the time, but he is not above letting a few cuss words slip. Charlie also displays some grounding in his idealism, understanding that not all demons can be redeemed, or even likely to change for the better. He displays sensible hesitation when confronted with an ambiguous deal from Alastor, the notorious Radio Demon, refusing the shake his (Alastor's) hand and using his (Charlie Morningstar's) status to make demands of him (albeit with some sheepishness). 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).
