Q. What was with the power multipliers?
A. To put it in layman's terms Beerus’s universal feats came from fighting Goku when he first attained the God form. He’s still stronger than Goku after gaining the Super Saiyan Blue x10 Kaioken form. So how do we break down the power multipliers?
Super Saiyan Blue is literally the Super Saiyan form of the normal God form, which we know has a 50x multiplier. Then Kioken is another 10x since it's a literal multiplier in power.
So that’s a total of 500x. This was more than the unofficial “multiplier” for Galaxia. Which was basically an 8x multiplier based on Sailor moon defeating 8 of Galaxia’s minions at once.
Now we did toy with a few other ideas for higher multipliers for Galxia, given we’ve seen others take multipliers a bit higher
. I think at most we’ve seen claims she could be tens of thousands of times universal based on some comparisons to her Silver Crystal and the Tairon Crystal. Though it’s worth noting this "tens of thousands" of times stronger statement was comparing the Tairon Crystal to a past version of the Silver Crystal, not Usagi’s power during the Stars arc. (Peep how it says a “Long Time Ago”).
That said this statement was made when Usagi jumped from her “normal” Sailor form to her “Super Sailor” form. Let’s roll with the fact despite it likely being hyperbole (it probably was) and the number being different in other translations for a second. There are some arguments that Usagi in her normal form could be as strong as her eternal form, so I guess the idea is that if her human form is eternal level in stars, her strongest forms could be at least 10,000 stronger. This is a whole other argument altogether, but let’s run with it.
It’s pretty likely that Beerus isn’t much weaker than
Vegito Blue or
Broly since it’s generally only proposed that they “might” be stronger than him. Vegito in his base form is typically shown to be stronger than Goku’s strongest blue variant. Broly also fought Gogeta , who’s base form is similarly stronger than Goku.
So let’s break it down.
Assuming Goku and Vegeta fusing is a 2x power increase from Goku’s bluex10 form at least.
Base to SS is 50x
SS to SS2 is 2x
SS3 is 4x
So even without entering the god forms Vegito is another 400,000x
And of course the god forms for Vegito would increase that even farther.
Even speculating the original god form required power from 5 saiyans so we could lowball a 5x multiplier.
The another 50x for Blue
That’s 100 million x and you can add another 3-9x cause of the size of the Dragon Ball universe(or high end was about 100x). There's also likely other increases in power you can extrapolate onto that if you want(like Goku's increase of power in base form). Finally, as a last resort, you could probably make a multiplier based on the power of feats between SS forms themselves the biggest of which is the jump from SS3 to SSG(Galaxy at most to universe is about a multiple of 2.6e26x)
Even if we start stacking this 10,000x claim with the multipliers already used for Galaxia in the ep, she would likely still come up short. The whole multiplier fight is a fight Galaxia really doesn’t want to start.
On a whole given benefit of the doubt, it's pretty easy to extrapolate power levels in Beerus’s favor if you want to go the whole power level multiplier route. Of course, we know not everyone likes to do this, so it was more of a side point. It’s also a bit too complicated to go into within the span of a single episode.
