Sunsa manga, version 1.0
Minoru Nonaka’s adaptation of the Sunsa arc was the shortest, occupying just two issues of Comic BomBom with a total of 62 pages. It began exactly in sync with the TV broadcast, but finished well over a month before Episode 39 was aired.
The Woodo paperback edition was published during this stretch, which meant Nonaka would have been working on the expanded version while still continuing his monthly serialization (a grueling schedule, to be sure).
Paperback editions
Since the Sunsa adaptation was the shortest in Comic BomBom, it got the most expansion when it was reworked for the paperback edition, published by Kodansha February 18, 1984. Nonaka tripled its length from 62 to 187 pages, which meant a LOT of lost scenes were added back in.
Sunrise Super Robot Series edition
