Battlestars: The Return of Convoy

Battlestars was a Japanese-exclusive series during Generation 1.

The Battlestars storyline began in February, 1991 and finished on November, 1991.

Story
Battlestars continued the storyline of the animated continuity, picking up where Zone left off, but was never actually animated. Instead, the story was told through a single issue of manga (which was a mail-away offer, no less) and "story pages" (story pages are two-page montage art spreads with narrative text smattered all over).

The Battlestars storyline revolved around the return of Optimus Prime as Star Convoy and his battle against Dark Nova and the resurrected Super Megatron.

Battlestars, story-wise, takes place at the same time as Operation Combination.
