Allen Walker Bio

Allen is a very polite, friendly, and well-mannered person, however he does not back down from a challenge. This is evident in his many confrontations with fellow Exorcist, Yu Kanda, who is the polar opposite of the friendly and social Walker. Because of his "parasitic type" Innocence he must keep his energy up and thus he possesses a voracious appetite and can eat massive amounts of food in a single meal. His mind is often on food even in serious situations.
He is a very loyal and protective person and has come to the aid of his friends on several occasions. He mostly remains optimistic regardless of what his situation is because of his vow to Mana Walker to keep moving forward and not give up. Allen Walker is kindhearted and treasures all life - vowing to save both humans and Akuma as long as he lives. He also has a "black" personality - deceptive, arrogant, and no mercy - which is usually shown when he is playing card-games or remembers about the debts left by Cross. This personality, a polar contrast to his usual behaviors, led many to wonder what Cross had done to him.
