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