Pi Patel
The narrator and protagonist. Pi is curious, devout, and more resourceful than he looks. His zoo upbringing gives him practical knowledge about animal behavior that keeps him alive. His religious faith gives him a framework for enduring what he cannot control.
Richard Parker
A 450-pound Bengal tiger who ends up on the lifeboat with Pi. Richard Parker is a constant threat and, paradoxically, the reason Pi stays focused and alive. His departure at the end of the novel hits Pi harder than almost anything else that happened at sea.
Pi's Father
The zoo director in Pondicherry. He is pragmatic and skeptical of Pi's religious enthusiasm. His lesson about tigers, showing his sons what a tiger actually does to prey, is the most important thing he teaches Pi, even if neither of them knows it at the time.
Pi's Mother
Quietly supportive of Pi's curiosity. In the alternate human story Pi tells the investigators, she appears as a character who is killed on the lifeboat. Her presence in that version suggests she may be the orangutan Orange Juice in the animal version.
The Japanese Investigators
Two insurance officials who interview Pi after his rescue. They push Pi for a believable story and end up receiving two. Their decision to report the animal version because it is the better story mirrors the choice the novel asks every reader to make.
Orange Juice
An orangutan who ends up on the lifeboat. She is gentle and maternal. In the animal story, she is killed by the hyena. In the human story, she likely corresponds to Pi's mother. Her death early in the voyage signals that the lifeboat will not be a safe place for anything gentle.
