Heave is, at his core, a mild-mannered astronomer, but he has sworn an oath to use his talents to fight the Decepticons. Nevertheless, he's a reluctant fighter at best, and always tries to temper the brash battle plans of his combiner partner, Barrage.
He's a member of the Astro Squad.
And, his name is really unfortunate.
- French name (Canada): Oh-Hisse
- Astro Squad (Micromaster Combiner Squad, 1990)
- Heave transforms into a gray radar trailer that is intended to be the rear half of a lunar exploration vehicle that he forms with his combiner partner Barrage. As a Micromaster Combiner, he can of course combine with any other Micromaster Combiner or Micromaster Combiner Transport to form new vehicles. He was only available in a six-pack with his fellow Astro Squad members Barrage, Blast Master, Missile Master, Moonrock and Phaser.
