What does being amped 1000x scale a characters attack potency specifically?

Being amped 1000x would significantly increase a character's attack potency by a factor of 1000. This means that their attacks would be 1000 times more powerful than they were before being amped. This would make them capable of delivering devastating blows and causing massive destruction with their attacks.

Where would they scale specifically? Star level, planetary, universal?

The specific scale at which a character's attack potency would increase when being amped 1000x would depend on their baseline power level before the amp. If a character's baseline power level was at a city level, being amped 1000x would likely elevate them to at least a country or continental level of attack potency. If they were already at a planetary level of attack potency, being amped 1000x could potentially elevate them to a star level or even universal level of attack potency.

Ultimately, the exact scale at which a character's attack potency would increase would depend on their individual power level before being amped and the capabilities of the specific character in question.

Ok, so if an above average human got amped 1000x where would that specifically scale their attack potency? Planetary? Universal? Star level?

If an above-average human were to be amped 1000x, their attack potency would likely scale to a planetary level. This means that their attacks would have the destructive capability to cause damage on the scale of entire planets. It would be highly unlikely for an above-average human, even with a 1000x power boost, to reach the levels of attack potency associated with universal or star-level power.

Therefore, in this scenario, the amped above-average human would most likely be at a planetary level of attack potency.
