Light speed and country level DC are handed out like candy by powerscalers of all communities, though OP fanboys are particularly bad about it. I don’t think people realize just how fucking fast light is, or how big your average country is.
Even as a big OPM fan, I wouldn’t put someone like Flashy Flash or even Monster Garou and Platinum Sperm at light speed. Also, even if a mangaka explicitly calls their characters “light speed,” it really doesn’t matter if the feats don’t back it up, because most mangaka probably don’t understand how fast light truly is and are just being hyperbolic to hype up their characters. A mangaka’s opinion holds no weight in crossverse battles. To call a character light speed, you need a feat of them traveling from point A to point B in an amount of time (if not explicitly stated) that can be reasonably assumed to be short enough that they’re moving at light speed. For example, a character going from Earth to the Moon in an amount of time that is clearly no more than a few seconds would be a light speed feat
