Pretty Cure Scaling Part 6 (DokiDoki):
10x is the number important for scaling the Cures up (only 2x for Ace since she was already so far above them).
Speed: Going to go off of the lightning feats, this increase would make them
Sub-Relativistic. In Resolved form, they should reach
Sub-Relativistic+. Higher in Engaged and Parthenon.
Lifting Strength: Ace and Heart hold up King Selfish's foot when he tries to crush them. Using the square-cubed law, King Selfish should be about 1.655284725x10^10kg. They didn't lift him off the ground, just stopped themselves from getting crushed. So, the Cures are possibly
Class G.
AP: Would only get 2x off of Regina's feat since the Cures (sans Ace) needed to reach that point in the first place. That said, since Resolved is 5x, that means even the base Cures back than would be
8-B, than 8-A once they get the 5x boost and they stay in
8-A after the 2x (all this not counting Melan's feat). For Resolved form, they would be
low 7-C.
And now for the Big Bang Statement. "Any girl with a powerful enough emotion to protect others can become a Precure!
And that power can rival even our universe's Big Bang!". This was spoken by Jonathan in the last episode. So, this could have two meanings:
1) the cures individually rival the big bang (unlikely that's what he meant give we see Parthenon mode, though thanks to All Stars this would be true).
2) Parthenon Heart who absorbed all the other Cures powers and was curbstomping Proto-Selfish.
So, what do we know? Well, we know that Proto-Selfish conquered the universe, which while that fact alone wouldn't make a character universal, it does give the context of it being possible. While Jonathan could know the actual power of the big bang (same way we do), it could also just be hyperbole. I lean more towards probably just hyperbole, but what do you think.
