I'm incredibly skeptical that series makes it into megaversal lol
It outlines the basic requirements for what a megaverse would be, but also contradicts itself in multiple places. The best I was able to decipher from all the jargon would end up at multiversal+ and I've seen people in SB of all places even argue against that because there are clearly places where the text refers to a finite amount of universes being affected
it's incredibly weird and the series itself loves being blatantly hyperbolic about shit. Like there's one point where they're described as "infinitely faster than infinite speed" and another where Alovenus is said to be able to easily defeat "an omnipotent" lmao
Even the statement about countless realities is contradicted in the same line about millions of worlds. The only reason I got multiversal+ at all was by assuming the infinite 'higher realities' all contained universes, which is the only way you arrive at an endless number of universes with those SB feats
either way this series is actually a textbook example of why Dimensional Tiering can't be used to gauge strength across most fictions.
