Dean's robot companion.
Created by Dean as his first creation out of the army, Mia was named after going M.I.A when it wandered off for a day due to an error later corrected in its creation process. Programmed with a complex response system but not quite self aware yet. Dutiful and loyal to the last.
Mia is fully equipped for combat, its mobile form protected by simple but effective armour an implemented with a neutral female voice node. Dean put everything the army had taught him into making it capable of holding her own in a fight. The lack of need for sleep or nourishment, in addition to being completely immune to poisons and diseases makes for a tremendously useful companion when scouting and scavenging, also letting Dean sleep peacefully at night knowing the never faltering robot watches over him.
