Jawbreaker is a character from He-Man and the Masters of the Universe.
Jawbreaker is a hulking robot who works for the Slavemaster. He can transform his clawed hands into many different weapons, including sleeping gas projectors, net launchers, flamethrowers, stun beams, and buzzsaws. However, he is not very intelligent and can easily be fooled.
When the Slavemaster captured Orko, he was displeased with the Trollan's work in the mines and ordered Jawbreaker to capture the strongest man on Eternia. He-Man allowed Jawbreaker to capture him, but broke free of his manacles and beat Jawbreaker into submission when the robot brought him to the mines. Both Jawbreaker and his boss were apprehended and taken to Castle Grayskull, where the Sorceress sent them back to their homeworld to stand trial for their crimes.
