Battlestars: Return Of Convoy

Battlestars depicts Convoy revived by the Destrons after his death in Headmasters initially as the evil False Convoy. He battles the Cybertrons but is defeated and then reborn as the Ultimate Cybertron Commander Star Convoy with Zone Energy. Star Convoy is also reunited with Hot Rodimus (Hot Rod outside of Japan) as his Micromaster partner. Galvatron, thought to be buried alive and trapped forever in the Arctic during Headmasters, is reformed into Super Megatron by Dark Nova and proceeds to battle with Star Convoy and the other Cybertrons, including Grandus, Skygarry, and Sixliner.

After initially defeating the Cybertrons, Super Megatron gets subsequently destroyed by them. Dark Nova then rebuilds him into Ultra Megatron. Despite being even more powerful than before, Ultra Megatron is again defeated by Star Convoy and the Cybertrons, but in near-death, merges with Dark Nova to become Star Giant, a six-armed, tentacled mechanical beast. Star Convoy and the Cybertrons battle and eventually defeat Star Giant, ending the series.

Star Convoy is briefly mentioned in the sequel Operation Combination, as having left Earth to do battle with the mysterious, next Destron Emperor of Destruction Scrash in outer space.
