Allen Walker

About
Allen Walker is also one of the exorcists who work at the Black Order since the beginning of the story. His has a Cursed Left Eye which was made when Mana was turned into an Akuma. His Innocence is his Left Arm which he can turn into a claw. His biological parents had abandoned him because of his left arm. Whenever his left arm is not activated, it would be red and wrinkly with the Innocence Cross embedded into his arm. Allen is a parasitic-type exorcist. He was also only 15 years old when he joined the Black Order. Both his Innocence and his left eye evolve. His Cursed Eye evolved into a Level 2, but in the Manga, it evolved all the way to Level 3. His left arm changed appearance and he also had another type of Innocence which was called Crown Clown. It looked sort of like a white cape with a mask behind. His left arm can changed into a sword called Sword of Exorcism. He also went up to the point breaker in one of the episodes. Komui explains that this meant that someone was gonna become a General.

Relationships
Mana was Allen's adoptive father and his brother was Nea Walker who was a Noah killed by the Earl a possible 35 years ago. Mana was a circus clown and had picked up the abandoned Allen. He was turned into an Akuma by Allen. He told Allen to destroy him, but after a few times, Allen would always say ' Run Mana!' Mana then later on make Allen's left eye cursed by cutting it and it bled. Mana was then destroyed by Allen after his left arm Innocence had activated. Lenalee was considered as one of Allen's best friends. She is also his team mate fighting Akuma. she also works at the order, but she is a different type of exorcist. Both Allen and Yu are rivals as shown in every episode. Kanda would always call Allen 'Moyashi' meaning beansprout in Japanese. Anyways, they're both total rivals. The General was also Allen's Master. He disappeared after Allen was in India. Later on, he shows up and still annoys Allen a bit. He is usually called a 'womanizer' because he always was in pubs with the gals/women.
