Fiction
Cybertron cartoon
Drill Bit was working with Metroplex at Gigantion's main construction site when Optimus Prime and his team arrived from Cybertron. He detached from Metroplex to greet Six-Speed and the other returning Mini-Cons from the Autobots, and even threw in a few good hugs for their human friends as well. He's a happy guy, that Drill Bit. Giant After Metroplex joined the Autobots, Drill Bit and his partner teamed with Optimus Prime, Vector Prime and the Mini-Cons in taking one of four possible paths deep underground to find the Cyber Planet Key of Giant Planet. City
While exploring the ruins of Gigantian, Drill Bit, Bud Hansen and the other Mini-Cons uncovered a lost Mini-Con city. They also ran into Scourge, who attended Bud's "leadership seminar" with them. Scourge After reaching the Lemuria at the core of Giant Planet, Metroplex was forced to fight the renegade Gigantian Menasor. Their battle ended when Drill Bit and Menasor's Mini-Con Heavy Load lept in the way, forcing their bosses to reach a peaceful resolution. Their efforts were successful, and so Menasor and Heavy Load joined the Autobot effort. Optimus
After the black hole was closed and Galvatron was defeated, Optimus Prime proposed the Transformer worlds restart the Space Bridge project which their ancestors attempted so many millennia ago. The construction conscious denizens of Gigantion were quick to jump on-board the project. Metroplex and Drill Bit assumed command of the starship Lemuria alongside Brimstone, Undermine and Signal Lancer. Drill Bit and the Gigantian Mini-Cons had a brief teary good-bye with Jolt and the Recon Team, who had chosen to remain behind on Earth. Beginning
