Demonic Descent: Dylan's Lost Salvation and the Terrifying Reign of Lucifer

Question: Write the sad, creepy, and scary alternate ending/take to this story: https://www.theinternet.io/articles/ask-ai/dylan-the-dylanus-melodies-of-power-in-a-world-where-music-is-magic-dylan-black-and-emma-find-themselves-on-an-extraordinary-adventure-as-the-chosen-protectors-of-their-homeland-they-harness-th/ , where Dylan encounters Lucifer Morningstar (the king of Hell from the adult animated series Hazbin Hotel), who arrived from the underworld, and Lucifer quickly influences Dylan's mind (against Dylan's will and his best efforts to fight off those influences) before Dylan gave in and completely forgotten his old life (despite his previous fears of becoming a demon before his influence), thus making him want to take over the world and leading Dylan to (wrongly) believe that he is and always has been the son of Lucifer himself (and Dylan loves that idea and is happy about that) and no longer remembers Black, Emma, nor being a mortal and savior of his homeland, being given a new male name that starts with "D" (not Dylan anymore). After being given every same demonic and angelic powers as well as immortality (unable to age and now stays young forever) that Lucifer has, he kidnaps Emma to make her his queen (using his new supernatural powers onto Emma to instantly change her outfit into a queen outfit and make her forget her past self as well as remembering that she is Dylan's wife/queen) as well as terrorizes and takes over Earth as the world's king alongside Lucifer Morningstar, thus turning Dylan into a villain like Lucifer Morningstar himself, who also now rules Earth (in addition to Hell). For Dylan the Dylanus's appearance, he is a 4.9 foot tall, 15 year old boy who has a lean build for his size, tan skin, medium-length brown hair (that reaches his chin, although not covering his face at all), and has green irises. He wears a dark blue hoodie, a lighter blue t-shirt underneath, and cyan wear jeans. He also has white socks underneath his black tennis shoes, which have an x-shaped gray marking on each of his shoes' tongue. Before Lucifer's influence, Dylan was a kind, considerate, smart, and understanding character, who was a love interest to Emma (his girlfriend) and was playful around his slightly older, smarter brother Black. Before his influence and despite his small frame and being a teen, he goes in the way to protect his homeland against various villains and monsters (always successful, even if some were more difficult than others). Despite these traits, he did have some flaws before his influence, such as his intolerance to swearing (which aren't present in his homeland), being quite weak naturally without superpowers (which he actually did not have and only obtained them when using special devices), and once had fear of vampires and demons alike since he previously viewed them as nothing more than pure evil monsters. After being completely and permanently influenced by Lucifer Morningstar, he now wears a white high collar tailcoat suit, long white poofy pants, a black bowtie, a pair of black gloves, black knee-high heeled boots, and a red undershirt with white stripes. He also now wears a wide-brimmed white top hat, with a golden snake and red apple over golden spikes reminiscent a crown. On his left pinkie, he now wears a golden ring. Dylan in Lucifer's influence carries an apple-topped black cane that matches his hat. Dylan in this state has pure white skin, red cheeks, purple eyelids, yellow iris-less sclerae & red slit-shaped pupils, and blonde hair, unlike his previous self. Dylan in his influence no longer has any known weaknesses and has every supernatural angelic and demonic powers that Lucifer has. Like Lucifer, the hell-influenced Dylan is never short of puns, quips, or jokes, and he is zany, self-indulgent, easily bored, and jaunty, a witty and charismatic showman with a goofy and silly charm (emphasizing his love of polka music), while simultaneously maintaining an air of regality and menace to avoid making others feel too comfortable around him. Due to being influenced, Dylan now cares for Lucifer Morningstar and sees him as Dylan's father. For Lucifer Morningstar's appearance, he has pure white skin, blonde hair, thick black eyebrows, black lips and a mouth full of sharp white teeth, with a biologically mid-to-late 20s aged body (despite being thousands of years old and being immortal). He has no visible ears or nostrils, giving him a less "human" appearance. His eyes (which don't have irises) are yellow with red slit pupils resembling those of a snake. He, like his daughter (Charlie Morningstar), has red cheeks. His eyelids are purple which give the appearance of eyeshadow. He wears a white high collar tailcoat suit, long white poofy pants, a black bowtie, a pair of black gloves, black knee-high heeled boots, and a red undershirt with white stripes. He also wears a wide-brimmed white top hat, with a golden snake and red apple over golden spikes reminiscent a crown. On his left pinkie, he wears a golden ring. Lucifer carries an apple-topped black cane that matches his hat. He has a very thin body (but is still powerful due to supernatural angelic and demonic powers) and he is slightly shorter than his daughter, Charlie, and his wife, Lilith, but he is still quite tall. Never short of puns, quips, or jokes, Lucifer Morningstar is zany, self-indulgent, easily bored, and jaunty, a witty and charismatic showman with a goofy and silly charm (emphasizing his love of polka music), while simultaneously maintaining an air of regality and menace to avoid making others feel too comfortable around him. Lucifer is a husband to Lilith Morningstar, and they both love each other very much, being described as "passionate, cheesy lovers" by some other demons. For Black the Dylanus's appearance, he is a 5 foot tall, 16 year old boy who has a lean build for his size, tan skin, medium-length black hair (that reaches his chin, although not covering his face at all) with red streaks running down, and has dark gray, almost black irises. He wears a black hoodie, a dark gray t-shirt, and pale gray jeans gray. He also wears white socks underneath his black tennis shoes with golden ankle-bracelets. In addition, Black's jacket has light gray artificial fur on the top and on the ends of the sleeves, where they are outlined by the golden bracelets on top. Black is a serious, smart, considerate, and understanding character, who is a slightly older brother to Dylan, who is more playful and kind. Despite his small frame and being a teen, he, along with his brother Dylan, goes in the way to protect his homeland against various villains and monsters (always successful, even if some are more difficult than others). Despite these traits, he does have some flaws, such as his occasional annoyance to Dylan's playful demeanor, being quite weak without superpowers (which he actually does not have and only obtains them when using special devices), and has fear and demons alike since he views them as nothing more than pure evil monsters. For Emma the Dylanus's appearance, she is a 4.7 foot tall, 15 year old girl who has a lean build for her size, tan skin, long blonde hair (that reaches the back of her neck), and has deep chestnut brown irises. She wears a pink jacket, a lighter pink shirt, gray bra, short, small dark red skirt, dark purple leggings underneath her lighter purple shorts, a pair of pink socks and light gray tennis shoes with a pink heart on each of the shoes' tongues. Emma is a somewhat serious, very considerate, and kindly character, who is the same age as her boyfriend Dylan. Despite her small frame and being a teen, she, along with his boyfriend Dylan, goes in the way to protect her homeland against various villains and monsters (always successful, even if some are more difficult than others). Despite these traits, she does have some flaws, such as her occasional annoyance to Black's technology-making habits that causes problems (for Emma, Dylan, and others), being quite weak without superpowers (which she actually does not have and only obtains them when using special devices), and has fear and demons alike since she views them as nothing more than pure evil monsters. There should be quotes for this alternate ending story so we would know what the characters are saying.
