Michael and Lucifer - Two By Two (Good Omens Lucifer Crossover, partially AI)

The ending is inspired by AshleighGates' fanfictions, especially "Shine, angel, shine" (https://archiveofourown.org/works/744...) PLOT: Michael and Lucifer are created from the same piece of matter, making them twins (only the Archangels are actual siblings in this head-canon, so Crowley and Aziraphale are not related like all of the angels in "Lucifer"). Though they both tend to get annoyed with Michael being serious and Lucifer more fun-loving, they are there for each other. Michael even gives him her Blessed Coin for protection against miracle blockers. Over time, Lucifer gets annoyed with the plans for the humans and confronts his mother, but Michael doesn't take his concerns seriously, eventually leading to his Rebellion. Michael immediately chooses Heaven and the Great Plan and fights against Lucifer and he Falls. Only after he is gone from Heaven for good, does Michael truly realize the consequences of her actions and the sadness surfaces before her emotional mask slips back on. The two sides grow into a bigger and bigger rivalry over the centuries. Lucifer stays in his demon form longer to be feared and respected in Hell. Both he and Michael grow lonely as leaders who still follow the Plan. But when the stress of Aziraphale getting the promotion as Supreme Archangel (a job that Michael craved and Aziraphale never truly wanted) gets too much, Lucifer feels his twin's emotional turmoil. Michael is surprised to find that Lucifer has kept her Coin for all those millennia and he can snap her out of her precarious mental state. In the end, everyone gets what they want: Aziraphale goes back to Earth, rekindles his love with Crowley and they move in together, away from Heaven and Hell, on their own side for humanity. Michael and Dagon are together in secret (Heaven and Hell are still officially enemies) and they both care a lot about their respective jobs and each other. Michael finally gets to be the new Supreme Archangel and Lucifer watches her promotion ceremony from his office, since he is now allowed to attend, proud of his sister. Now they can go back to goodheartedly annoying each other as leased of their offices. I used AI tools for the masking, removing the background voices in the music, parts of the backgrounds, Michael's gala ceremony, the fight scene and the wings and the kiss between Michael and Dagon.
