About Wrath
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, so Dante takes Ed's limbs from him to keep him quiet. He is later 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. (Taken from Wikipedia)
