"Metamorphosis of Alastor: From Radio Demon to Hell's Forgotten Fly"

Prompt: Write the transformation story of Alastor (from an adults cartoon/animated series Hazbin Hotel) turning into a common green bottle fly (Lucilia sericata) female from real life, complete with gender change (turning from male into female instantly), shrinking, body changes (his toothy jaw turning into an insect proboscis, losing vocal cords (making him unable to talk or make other sounds), his sides growing an extra pair of insect limbs (his arms and legs becoming identical insect legs), his back growing a pair of insect wings, his eyes turn into larger pure red insect eyes, his body becoming a segmented insect body, his posture completely shifting and falling from his previously bipedal posture to a six-legged posture, a segmented insect body, his rear end (aka a butt or ass) and male genitals merging together and inflating into a huge insect abdomen (being filled with fly eggs to help her species by laying eggs, and Alastor starts laying eggs during the mind/mental changes), etc), age change, and mind/mental change (with Alastor's personalities and memories being being replaced with a female green bottle fly's personality and memories, with the voice inside his head telling him that he was never Alastor and never a demon to begin with and tells the newly-transformed being that he (now she) was always a common green bottle fly and that she was born a larva after hatching from an egg with her siblings just 24 hours after her egg was laid by her mother before the fly (formerly Alastor) started to eat dead organic tissue from a carcass and she later had formed a cocoon around herself a few days later, and the voice tells her that she had just emerged as an adult fly about an hour ago after emerging from her pupa between 6 to 14 days, despite Alastor's understanding of her language and words dimming/shrinking to nothingness, making her completely unable to understand languages or words, making words and language just vibrations/noises to her, and she only knows how to communicate through pheromone and odor sensing, before the voice in her head encourages her to lay her eggs to help birth the clutch and populate her species as her kind always had (even her mother, also a common green bottle fly). Despite her best efforts of holding onto the memories and personality as Alastor, she has lost all of them and has completely turned into a common green bottle fly female). For Alastor's appearance, he is a slim, dapper sinner demon with 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. For the female green bottle fly's appearance (after Alastor turned into her), she is 10–14 mm (0.39–0.55 inches) in length – slightly larger than a house fly – and has brilliant, metallic, blue-green coloration with black markings. She has short, sparse, black bristles (setae) and three cross-grooves on the thorax. The wings are clear with light brown veins, and the legs and antennae are black. The flies are extremely prolific; a single female common green bottle fly typically lays 150−200 eggs per clutch and may produce 2,000 to 3,000 eggs in her lifetime. There should also be quotes from the characters in this story so we know what they're saying and what they're thinking.
