The first change is immediately noticeable in the company credit screens. Both say West Cape Corporation, but only the first includes Yoshinobu Nishizaki and Toei Animation Co.
The next one comes up in the first shot of the opening montage. There are numerous color tints that differ between the A and B versions, this one only being the first. Version A is also loaded with caption titles (as we’ll see later on) but in this case there was none. The addition of a caption reading ‘Formation of the Solar System’ was added to Version B.
Here, too, viewers of Version A probably didn’t know exactly what they were seeing. Version B labeled it ‘Earth,’ meaning this was the formation of our planet. A helpful thing to know, really.
Here’s our first glimpse of Water Planet Aquarius, drifting through the early solar system and about to flood the primordial Earth. In Version A it was only dimly visible past the planetary halo, so the shot was changed and clarified for Version B.
A shot of the Aquarius flood cooling Earth’s surface, very different from A to B.
Then another shot of Aquarius, with the surrounding clouds toned down a bit in B. Still not quite enough to make it out, though.
Random galactic phenomenae, very different from A to B.
The opening narration ends, giving way to production credits. The galactic vistas are the same, but Version B enhances them with chroma effects.
The scene cuts to an extremely wide view of the galactic collision, which was completely redone for Version B.
Another production credit.
Another extreme wide shot, the same art this time but greatly processed for B.
Another production credit.
A closer view of the collision with stars and planets taking the impact. Incidentally, this massive intergalactic event was later explained as a temporary dimensional crossover, which is why the red galaxy isn’t seen again after this opening montage.
A planet takes the full brunt of the cataclysm. The flying debris was made more visible in B.
More mayhem and destruction as worlds collide.
Back to an extreme wideshot with different cropping and credits
The final credit for Creator/Executive Producer/Etc. Yoshinobu Nishizaki. It would have been a good opportunity to depict the red galaxy vanishing back into a dimensional void, but it was not taken.
