Who is the static character in the story the scarlet ibis?

In "The Scarlet Ibis" by James Hurst, the static character is the narrator's brother, Doodle. Unlike Doodle, who undergoes significant changes and development throughout the story, the narrator remains largely unchanged in his pride and ambition. This contrast highlights the themes of growth and the burdens of familial expectations, ultimately leading to the tragic outcome. Doodle's steadfast innocence and vulnerability serve as a poignant backdrop to the narrator's evolving character.
