Frostbite.
Buccaneer had always been a bit of an oddity amongst those in the military who bore auto-mail.
He was the first soldier stationed in the Northern region to require a prosthetic limb, and the mechanic that had initially been sent out by the military had no idea how to adjust his designs to fit the situation.
After a few close-calls with frostbite, the at the time Colonel Armstrong had the 'incompetant fool' dismissed and set her own men to the task of finding a mechanic in the North, one who knew what needed to be done to make auto-mail 'Briggs-proof'.
They soon found Sherman Wallace, a man who had invented unique sort of automail, as well as techniques to keep the metal from adhering to the skin when temperatures dropped.
Shortly after, Buccaneer underwent surgery again, this time at the fort, and had a new, cold-weather automail port attached to his shoulder and nerves, this time with a rubber matting beneath the alloy to assist in preventing frostbite.
So far as he knows, he's the only person to have such an addition to his automail, and it gives him an advantage over other users of automail when out in the harsh snows of the North.
