Units are mechanically engineered suits that when worn, give abilities that rival the speed and strength of an Exceed. They artificially increase the agility, strength, and damage immunity of the wearer, and different Unit suit versions have various other abilities. Created by the Equipment Smith, they are his answer to the ≪Blaze≫ and the goal to achieve Absolute Duo.
Units also seem to have minor ≪Blaze≫ immunity, as demonstrated when Lilith shot a soldier wearing a Unit, but taking no damage from her attack. Unit users uses conventional weapons such as guns, that can cause bodily harm and even death, as the Unit does not usually come with its own weapons.
