Drillbuster is an Autobot Micromaster from the Zone portion of the Generation One continuity family.

Drillbuster is the Micromaster partner to the Autobot Road Fire, and helps him fend off the Nine Great Demon Generals.



  • Road Fire (Autobot, 1990)
Japanese ID number: C-349
Drillbuster transforms into a Cybertronic drill tank. He was only available with his larger partner Road Fire, whose "base" mode has a ramp mechanism to launch the tiny Transformer.
  • Big Powered (Multi-pack, 1990)
Japanese ID number: C-353
All three Powered Masters (Sonic Bomber, Dai Atlas and Road Fire) as well as their Micromaster partners were also available in a great big gift set.


  • Drillbuster is unique among the Powered Master Micromaster partners in that he does not transform into a real sports car (or a close-enough approximation).
