Original script production line of Gatchaman II

While the sequel of Gatchaman II had a smaller episode count than the original series and it is less analyzed by fans in comparison, it can be witnessed that some scenarios would also bear much different titles and placement than the finalized episode order.

Different copies of some scenarios can also show that certain episodes could be moved up or down in placement through production, and some early write-ups in Animage also show different intended airdates for some plots that would later be rescheduled and pushed back.

Since a complete listing of scripts has not yet been ascertained, it is unknown if the amount of scenarios exceed the amount of approved broadcast scripts as with the original series (or if numbers had accidentally been skipped), or if some scenario numbers were duplicated by mistake. The below listing attempts to reconstruct the production line and early titles where known, with many exact placements still unconfirmed and any preliminary titles for certain episodes also uncertain.
