The Sewing-Life Alchemist Shou Tucker committed a mortal sin when he used his daughter Nina and the family dog Alexander to create a talking chimera for the sake of scientific progress, dying not long afterwards. His soul still stating his case as being one of scientific pursuit, a pitying Celestia gives him a second chance at life in Equestria. A tan unicorn named Show Bucker continues his work in Ponyville working with creating chimeras for The Canterlot Institute when he is plagued by horrific images and visions he cannot explain. Perhaps Twilight and others he befriended in Ponyville can help him out?

This is and will be a disturbing story as it develops. Then again, creating a story featuring one of the most evil Fullmetal Alchemist characters reborn within the MLP backdrop will probably merit it as such.
