Huskisson

Young yet swollen with pride in his own genius, Huskisson lives in a castle-like complex that floats on water southwest of Amestris, raised over the uranium mine he runs. The lethal work has scarred him: the skin around his eyes is heavily damaged, and he keeps it hidden behind a metal mask.

Brilliant and insufferably arrogant, Huskisson treats human lives as acceptable fuel for advancement, insisting that progress demands sacrifice. He openly scorns alchemy while quietly studying it himself, and he turns violent the moment his brilliance goes unrecognized, lashing out at anyone who refuses to bow to his vision of science.

Around 1914 he completes a powerful uranium-fueled bomb and loudly publicizes it, hoping to win the State Military's backing, which draws the Elric brothers to his door. Mistaking the armored Alphonse for the Fullmetal Alchemist, he lectures the boy on the technological surge he claims to lead and shows off the weapon, only for Al to reject it as one more instrument of destruction. Enraged, Huskisson traps the armor and attacks with mechanical drills hidden under his clothes, then reels when he finds the suit empty.

Edward arrives and reveals the brothers never meant to help, having come only to investigate the dark rumors around the facility. Huskisson flees to the mine and fights them with a massive drilling rig, but their alchemy overwhelms it. Cornered, he threatens to detonate the bomb and unveils a plan to transmute a pile of dead miners into soldiers who are part man and part machine, then to seize control of Amestris. He activates a transmutation circle drawn on cloth, and the attempt at human transmutation drags him before the Gate, where the Gate Children pull his whole body into the void. Edward's rigged explosions sink the facility, but the uranium bomb slips into the real world and falls to the Thule Society.
