Title: "Sinister Transformation: Loona's Descent into Darkness"

Prompt: Write the transformation story of Loona (from an adults cartoon/animated series Helluva Boss) turning into Alastor (from an adults cartoon/animated series Hazbin Hotel), complete with gender change (turning from female to male, her feminine curves vanishing, while her breasts vanishes, and her vagina, ovaries, and uterus invert themselves before pushing out of her nether region as testicles and a penis), age change, height progression, and mind/mental change (with Loona's personality and memories being completely replaced with Alastor's personality and memories, despite her best efforts of fighting these new personality and memories, making her, now him, completely forget that he was ever a female hellhound, a daughter to an imp father Blitzo, and being named Loona, and only remembered being Alastor the Radio Demon). For Loona's appearance, she is a hellhound with a wolf-like appearance (she is bipedal like all hellhounds of the Hazbin Hotel series and Helluva Boss series). She has a pointed, dog-like muzzle with sharp and pointy teeth, and a dark grey nose. Her eyes have red sclera with white irises, and she wears grey eye shadow and black winged eyeliner for makeup. She also has a piercing on her right eyebrow with a black hoop for jewelry. Her fur is white with grey encircling her face, grey patches on her shoulders, and long, voluminous silver hair swept to the side to reveal her dark grey ears - the left of which is pierced with two small, black hoop earrings, while the right is ragged. She has a large, dark grey bushy tail with white on the underside. Her outfit features a large, spiked black choker around her neck. Her tattered grey, off-the-shoulder crop-top is held up at the neckline by a series of crisscross spaghetti-straps that form an inverted pentagram. She wears black shorts that are tattered at the hems, with a white crescent moon detail on the right side. Loona accessorizes with black fingerless gloves and thigh-high black toeless stockings, with her black claws protruding due to her digitigrade stance. Loona is a cynical and choleric young-adult Hellhound, who was adopted from an orphanage by Blitzo when she was nearing eighteen years of age. Loona is lazy and shows little interest in matters that are going on around her. She also has a short-fuse temper and is often rude and apathetic toward her colleagues, particularly Moxxie, though her ire seems otherwise indiscriminate. When not looking at her phone, Loona is usually scowling at anyone in view. For Alastor's appearance (after Loona turned into him), he is a slim, dapper sinner demon with a human-like face, beige-colored skin, and usually has a broad smile full of sharp, yellow teeth. He is approximately 7 feet tall. He sports a pinkish-red cropped, angled bob-cut with black tips at the ends and two large, black tipped tufts of hair extending from the top of his head, evoking the ears of a deer. The style has an undercut at the back, and two small black antlers protruding from the crown, which can grow in size in his full demonic form. Alastor's eyes have dark-red sclerae, bright-red irises and thin black pupils (which can change into the shape of radio dials when shifting into his full demon form). His forearms and lower legs fade to dark grey, and he has red hoofed toes and red fingers. Alastor wears a red pinstripe coat with dark-red lapels piped with white, which is ragged along the bottom hem. Underneath this he wears a bright red dress-shirt with a black cross on the chest, and long black dress pants with matching bright red cuffs. He also wears a dark-red oval-shaped monocle, rimmed with black, over his right eye. He accessorizes with a black knotted bowtie with a bright red center, black gloves with red at the fingertips, and black pointed-toe boots with red deer hoofprints emblazoned on the soles. Alastor also carries a thin cane with a sentient vintage style microphone attached to it, which he uses to play sound effects and broadcast his voice. Alastor stands out from many of the more chaotic residents of hell for his well maintained amiable persona. He gives the first-impression of a good-natured and charming man, wearing a permanently wide grin on his face at all times. Alastor's behavior, mannerisms, and even his voice are similar to an old-fashioned radio announcer and speaks with a transatlantic accent, often using quaint anachronisms such as "the picture show" and refers to Charlie as a "charming demon belle". This playful dandyish exterior, however, obscures a much darker side to him - one with high levels of self-importance - and he will not hesitate to use physical violence when others don't act in line with his very particular values or expectations. There should also be quotes from the characters in this story (including Loona's profanity such as "fuck" and "shit" and so many more, but she would stop swearing once she turns into Alastor, making her, now him more refined and less profane) so we know what they're saying and what they're thinking.
