@Joshless Actually wait, where are you getting the idea/metric that it took the Genesis Frog "billions/millions of years" to be destroyed from? That's contradicted a bunch in the comic itself. For example, the Tumor exploded within a few minutes of it being activated, and what we see on screen during the actual act of destruction is extremely quick. We even see the destruction around where Earth is starts at a relative point in both iterations of the universe (Around 400 years after Entry, when the Exiles and Dirk and Roxy are present.)

I think it's just because the attack was literally sent from outside of time AND it's meant to be affecting multiple timelines at once (since it's destroying a Genesis Frog which contains multiple timelines), that it FEELS like it takes longer than it does. Either way, Bec just scales to Multiversal+ even without that feat lol.
