Missile Master is the leader of the Astro Squad. He's something of a control freak. He chose to be the back of the missile transport he forms (with his combiner partner, Moonrock) because that gives him control of the missile. Fortunately, Moonrock is so mellow, he lets Missile Master handle the driving as well.
- French name (Canada): Missilas
- Astro Squad (Micromaster Combiner Squad, 1990)
- Missile Master transforms into a red missile transport trailer that is intended to be the rear half of a missile transport that he forms with his combiner partner Moonrock. As a Micromaster Combiner he can of course connect to any other Micromaster Combiner or Micromaster Combiner Transport to form new vehicles. He was only available in a six-pack with his squadmates Moonrock, Barrage, Blast Master, Heave and Phaser.
