Hal is a supporting character in Disney•Pixar's 2008 animated feature film WALL-E. He is WALL-E's pet cockroach and only friend and companion before EVE's arrival to Earth. Hal is extremely resistant, as he manages to not only survive the devastated near-lifeless Earth, but also getting stepped on by WALL-E and shot by EVE without suffering 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. After the Axiom landed on Earth, Hal quickly approached the broken WALL-E and EVE, and returned to WALL-E's transport vehicle.
Hal makes a cameo in Ratatouille in Linguini's Apartment.
Hal also makes a cameo in Wreck-It Ralph, when Ralph looks for a medal in Tapper's washroom.
