Automail

Item from Fullmetal Alchemist by Hiromu Arakawa

Mechanical prosthetic limbs connected directly to the user's nerves — agonizing to install, requiring months of rehabilitation, and granting full functionality to those strong enough to endure the surgery.

Appearance

Gleaming steel and chrome prosthetics of varying designs — from sleek, lightweight models to heavy combat variants with built-in weapons. Visible gears, pistons, and connection ports mark where metal meets flesh. The nerve connection points are surgical scars surrounded by bolts.

Also known as: Automail, Mechanical Prosthetics, Auto-mail
