Metamorphosis of Alastor: Symphony of the Monarch Butterfly

Prompt: Write a transformation story of Alastor (from an adult cartoon/animated series Hazbin Hotel) turning into a monarch butterfly (scientifically named "Danaus plexippus") female from real life, complete with gender change (turning from male into female instantly), shrinking, body changes (his smiling toothy jaw turning into a butterfly proboscis, his back growing a pair of butterfly wings, his sides growing an extra pair of insect limbs (his arms and legs becoming identical insect legs), his eyes turn into larger pure black insect eyes, his posture completely shifting and falling from his previously bipedal posture to a six-legged posture, his torso body becoming a segmented insect body, his rear end inflating into an insect abdomen, etc), age change, and mind/mental change (with Alastor's personalities and memories being replaced with a female monarch butterfly'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 monarch butterfly female and that she has arrived to her nesting site filled with milkweed plants (the voice in her head urges her to lay eggs on the leaves of those milkweed plants to help populate her species), despite her quickly losing her understanding of words or languages due to becoming a simple insect, and despite Alastor's best efforts of holding onto her memories/personality of Alastor, turning her into a female monarch butterfly). 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 monarch butterfly's appearance (after Alastor turned into her), she has a deep black body with a few white spots on the front half of her body, and her wings feature an easily recognizable black, orange, and white pattern, with a wingspan of 8.9–10.2 centimeters (3.5–4.0 inches). Like all Lepidopterans (moths and butterflies), monarch butterflies (including the female monarch butterfly in this story) undergo complete metamorphosis; their life cycle has four phases: egg, larva, pupa, and adult. Female monarchs lay eggs singly, most often on the underside of a young leaf of a milkweed plant during the spring and summer. Females secrete a small amount of glue to attach their eggs directly to the plant. They typically lay 300 to 500 eggs over a two- to five-week period. There should also be quotes from the characters in this story so we know what they're saying and what they're thinking.
