Wrath (ラース, Rāsu) differs greatly between the anime and the manga. In the manga, Wrath is the true identity of King Bradley, the "Ultimate Eye". His eye, usually covered by an eyepatch, gives him the foresight to see all possible outcomes of a given situation, allowing him to predict the moves of any opponent before they happen. His favored mode of attack is with his sword, which he wields with great proficiency. Before becoming a homunculus Bradley was trained with a group of others to become the leader of the country. Once they were old enough, a Philosopher's Stone was inserted into their blood system, a process only Bradley was able to survive. Having once been a human, Wrath ages with time, a trait that irritates him since his body can't keep up with his eye's predictions. Because homunculi cannot reproduce he was given a family to keep up appearances: his "son", Pride, and a wife he chose himself.
In the anime, Wrath was created when Izumi Curtis tried to revive her infant child. Her attempt failed, and the infant's body was taken beyond the Gate of Truth. There the child, Wrath, grew up. When Edward Elric later lost his arm and leg while trying to revive his mother, Wrath took both for himself, allowing him to use alchemy and escape to Amestris. In addition to performing alchemy Wrath can merge with any object. Because he is the remains of his former body, he cannot be weakened like the other homunculi, though the cries of a child have a similar effect. After joining the homunculi, Wrath develops a mother-son relationship with Sloth. When he unknowingly helps to kill her (having merged with the remains of her original body) he becomes distraught and tries to revive her with human transmutation. He loses the limbs gained from Edward Elric, and is given automail replacements by Winry Rockbell. He appears again in Conqueror of Shamballa, doing constant battle with Gluttony. With Gluttony distracted, Wrath tells Alphonse Elric to use them both as sacrifices to open the Gate of Truth. Al does so and is able to reunite with Ed, while Wrath is able to reunite with the spirit of Izumi.
