Calculating Flashy Flash’s kick’s striking strength based off the kinetic energy formula. This is using Flashy at lightspeed (although he is at least this fast).
Kinetic energy formula- mass x veloticty squared x 0.5
Firstly mass. Google says that the average male leg is 16.68% of a person’s mass, and that the average person weighs 62 kg. As far as I can tell that’s male and female, but Flashy is pretty slim so it should be roughly even.
62 x 0.1668= 10.3416
10.3416kg is the rough weight of Flashy’s leg.
SoL is 299792458 m/s
10.3416 x 299792458 x 299792458 x 0.5=4.647283278x10 to the 17.
That’s a large number of joules.
In fact, it’s 464.7283278 petajoules
Thats multi-continental as defined by Vs Battle wiki.
Each one of his Flashy Kicks being multi-continental also scales Hellfire and Gale to that, and possibly Child Emperor (I can never remember which redraws are canon for Brave Giant).
It has come to my attention that I misread, and by VS battle wiki definitions this is only barely mountain level. Which is still very high.
This is something I think should be discarded.
