The Giant Magnet is a large orange junkyard magnetic attached to the T.C. (Tower Crane), and the climax main antagonist of The Brave Little Toaster.
He is the final antagonist in the film. He appears near the end of the film, when the main characters are sent to Ernie's Disposal, an automotive junkyard. During the song "Worthless", the Giant Magnet mercilessly kills nine of the Junkyard Cars, one by one, picking them up and dropping them onto a conveyor belt leading to a Crusher, which crushes them into tiny cubes, while Toaster and his fellow appliances try to find cover from the Giant Magnet. Unlike the Junkyard Cars, he doesn't have any expressions aside from a permanent scowl (and a confused look, briefly).
Being a cold and uncaring machine created to destroy, the Giant Magnet shows no sympathy for his victims and has no regrets about killing them. Although the Magnet is simply performing its job, like Elmo St. Peters, to destroy the cars, it later chases the appliances, deliberately picking up every object (or more) they hide under. When the Master arrives at Ernie's Disposal to retrieve his appliances, he grabs onto them just as the Magnet picks them up, being lifted into the air and dropped onto the conveyor belt along with them. As they are about to be killed by the crusher, Toaster jumps into the workings of the machine, using his own body to jam its gears. Crusher is disabled just in time, and the Toaster is repaired by the Master.
- The Giant Magnet is often considered the main villain in The Brave Little Toaster. T.C. and Crusher are the other villains. However, Crusher is the secondary villain for the junkyard scene.
