Mrs. Tucker

Once an ordinary human woman living in modest comfort, Mrs. Tucker is shown with blonde hair in a family portrait Nina drew. Her final form, however, is that of a human-based chimera, her body fused with an unknown creature into something able to speak yet longing only for death.

In her human years she stood by Shou Tucker through his repeated failures to earn State Alchemist standing. As his desperation deepened, the marriage soured into constant bickering within a few years of the wedding, and her patience finally gave way to grief once her husband's ambition turned monstrous.

Tucker's mounting obsession drove him to a horrific act: he used his own wife as the subject of an illegal chimera experiment, fusing her with another creature to produce a beast capable of human speech. He then spread a lie that she had walked out on the family for a better life while parading the talking chimera as proof of his brilliance, earning his certification. The single sentence the creature ever uttered was a plea to die.

Broken by what had been done to her and wracked with constant pain, Mrs. Tucker never spoke again and soon starved herself to death. Her fate went unavenged until Tucker repeated the atrocity on their daughter Nina, a discovery that nearly drove Edward Elric to kill him. She was glimpsed only in passing in the main story and received no proper introduction until Hiromu Arakawa's 2017 prequel gaiden, released to mark the live-action film.
