As mentioned before, the TV version looks very similar to Super Giant, in that both wear cowled costumes and capes. Each character also has super powers and flies. The movie version (produced by Toei) is different, as Prince of Space wears a streamlined costume, cape and helmet. He has no superpowers other than the invulnerability of his costume. He uses weapons (a wand-like laser gun) and flies a small spaceship.
Why should he have darkvision and be able to cast starfires.. this seems to say he just needs high protection

(I've got a bit of a problem with giving Jomon astral to be honest, but with a good reason a hero could get it if needed)
Why a second form?
