Gene Forrester
Gene is the narrator and the character whose inner life drives the plot. He's academically gifted but emotionally insecure. His jealousy of Finny leads to the accident, and his inability to fully confess or accept responsibility shapes everything that follows. The adult Gene narrating the story is still trying to make sense of who he was.
Phineas (Finny)
Finny is Gene's best friend and the novel's moral center. He's naturally athletic, genuinely generous, and almost entirely without malice. He breaks rules without guilt and inspires loyalty without trying. His refusal to believe Gene hurt him on purpose is both his defining trait and the thing that leaves him unprotected.
Leper Lepellier
Leper is a quiet, nature-loving classmate who enlists in the army and comes back psychologically shattered. His breakdown is the novel's clearest evidence that the war is real and destructive. He also serves as the witness at the tribunal whose testimony helps expose what Gene did.
Brinker Hadley
Brinker is Gene's classmate, confident and politically minded. He suspects Gene caused Finny's fall and eventually organizes the tribunal that forces the truth into the open. He represents the part of the Devon world that insists on accountability, even when that insistence causes harm.
Mr. Ludsbury and Dr. Stanpole
Mr. Ludsbury is a strict Devon master who represents the school's formal, rule-enforcing side. Dr. Stanpole is the physician who treats Finny both times and delivers the news of his death. Neither is a major character, but both mark the boundary between the boys' world and adult authority.
