He has also demonstrated himself to be extremely intelligent and skilled in military weapons.As a Homunculus, Bradley possesses a special kind of power in his left eye, giving him sight abilities that far exceed a regular human's eyesight; allowing him to read an opponent in battle and avoid oncoming attacks with little to no effort. This ability is known as the "Ultimate Eye".
