Hal

Hal is a character in the 2008 Disney/Pixar film WALL-E. He also makes a cameo in Wreck-It Ralph.

Role in the film
He is a cockroach that is WALL-E's friend and pet. Hal is extremely resistant: although he gets stepped on by WALL-E and shot by EVE, he suffers no harm.

Hal likes eating Kremies as his food. He stays on Earth when WALL-E leaves the planet because WALL-E orders him to do so.

Trivia

 * Although Hal is never referred to on-screen by name, he is named after producer Hal Roach. This also provides homage to 2001: A Space Odyssey’s HAL 9000.
 * The chirps that Hal makes were created by speeding up sounds made by a raccoon.
 * Hal and the Kremies he sleeps in references the myth that roaches and Twinkies (what inspired Kremies) are the only things that can survive the apocalypse.
 * Hal makes another cameo in Ratatouille.
