Wrath (2003 anime)

Wrath (Japanese:ラース, Rāsu) is a young Homunculus created by Izumi Curtis in an attempt to revive her son. He is a character exclusive to the first anime, named after another Homunculus from the manga.

Anime
In the anime, Wrath is Izumi's son, who died before or a little after he was born. She tried to resurrect him and failed. Wrath spent much time in the Gate, waiting and wanting to go out. The Gate opened while the Elric Brothers were trying to resurrect their mother. It was then when Wrath gained Edward's arm and leg.

Long after, he says, he opened the Gate himself and then lived on the same island where the Elric Brothers spent one month. After that, Wrath joined other Homunculi. As time went on, Wrath began to think of Sloth as his mother.

When Sloth was being repeatedly slashed by Lust as a distraction so Ed could get his mother's body part, Wrath appeared and took the body part before Ed, fusing it with himself. Then, Wrath went back inside and stopped Lust from attacking 'mommy'. Sloth tried to run away, but Ed followed her. Wrath was about to follow them, but Lust stopped him. They fought until Wrath found the locket with the hair of the person Lust looked like, and then sealed her.

After that, he went to "save" his mother. But in doing so, he fused himself with her, to "be closer to her". However, because he still had Trisha's (Ed's mother) bone fused with him, being so close to Sloth paralyzed her. Ed took that chance, and used alchemy to make Sloth evaporate.

Later, Izumi appeared and tried to convince Wrath to come with her. Wrath, insisting that Sloth was his real mother, didn't believe Izumi and ran off. He didn't appear again until he, Dante, and Envy were inside that strange palace building. He ran to Dante and Envy, clinging to Envy while begging "Please!! Please bring Mommy back!!". Envy kicked him off and Dante opened the gate with Rose's baby. The gate was opened, and black tentacles took Wrath's right arm and left leg, originally being Ed's arm and leg.

After that, he was left on the floor, until Ed was brought back to life after being killed by Envy. He and Rose talked and right before she was about to leave, Ed asked her to take Wrath with her. In the last episode, he was seen in the Rockbell resident, with an automail for his arm and leg and was living with Winry and her grandmother.

Conqueror of Shamballa
Later on, he appeared in Fullmetal Alchemist: The Conqueror of Shamballa. There, he was seen in the forest at first, where Winry found him and took him back "home". Then, when Alphonse came back after finding out that his brother was alive, Wrath anticipated what his intentions were. He led Alphonse to the Underground City, where they were attacked by a transformed Gluttony.

Wrath and Gluttony battled for a long time, until Wrath made it to a Transmutation Circle, where he intentionally let himself be bitten by Gluttony. Then, he told Alphonse that he knew he was planning to sacrifice himself to bring his brother back, claiming that he never wanted to see anything like that ever again. Alphonse tried to argue, but Wrath told him that he wanted to go to his real home, where "mommy" was. Alphonse went through with the transmutation, and Wrath was seen on one side of the Gate, and on the other side was Izumi. He was last seen, walking to her, and getting hugged by her, before the gate closed.

Powers and Abilities
Wrath is a homunculus, and thus has amazing powers of recuperation, strength, speed, and unaging longetivity. Futhermore, while in possession of Edward's lost limbs, Wrath displays the ability to perform Alchemy without a transmutation circle - something which is unique to both Alchemists and Homunculi. But his particular homunculus power is the ability to merge and fuse his body with virtually any matter, both living and inanimate, organic and inorganic, and can even accelerate the sped in which he merges through the Alchemy he uses. He also has the ability to morph his Homunculi limbs into pale white tentacle-like appendages to ensnare targets from afar.

Trivia

 * Wrath is the only Homunculus in the Fullmetal Alchemist continuity capable of using Alchemy, due to his right arm and left leg originally belonging to Edward Elric.
