I wanted the first sonic-rainboom to be caused by LOVE! (like how its SUPPOSED to be)
I wondered about that; clearly something is wrong in the original E7verse for this to be happening, yeah? I'm 99% sure this is an alternate universe (the giveaway being the un-engraved moon shots in AO).
Also these 'Swells', I don't THINK, have seven rings around them like the original Seven Swell phenomenon should. (So, its incomplete?)
Also, its not necessarily always created 100% from love; remember the first Summer of Love with Adroc and Eureka? That was a forced phenomenon so the Ageha Project could further its research. Eureka didn't love Adroc (well, she didn't have ANY feelings then) so that one was triggered by experimentation between Eureka, the Nirvash, and a human partner.
So... its POSSIBLE these hunks of Scubs dropping from Portals (along with the G-Monsters, lame as their name is) are results of experiments in the original E7verse. If it is, they'd probably need Eureka and someone else (and currently, Eureka, as far as AO is concerned, has disappeared for unknown reasons). Who knows? (Hopefully the audience will eventually. :I)
