Author Hiromu Arakawa integrated several social problems into the plot, such as the way Edward and Alphonse live as brothers after the death of their mother, Trisha. She also looks at how the brothers help people all over the country to gain an understanding of the meaning of family. When describing the character's personality, Arakawa comments that after his father's departure from home and his mother's death, Edward tried to replace the role of the man for the Elric family. As a result, Van Hohenheim's reappearance caused a shocking and terrified reaction in the character. Arakawa has noted that Edward is one of her favorite characters from the series, although she denied having the same personality as him when one of her assistants mentioned it.
