Just to clarify, I didn't make this calculation. This was all calculated by KanaNotBonnie and this is the original post. All the credit goes to them.

In the FNAF books, Nole's post-nut clarity causes the manifestation of his sorrow to create a storm 35 miles long that gets dispersed when he feels the touch of a woman.
As this is a dispersion feat, I will use height and distance.
It is 35 miles wide, along with being described as a dark black storm that blocks out the sun, which obviously implies a thunderstorm with that description, I will use cumulonimbus clouds.
Plugging this into a Cylinder Calculator, we get 79739.538679102 km^3, or 79739538679102 m^3.
Density of cloud air is 1.003 kg/m^3.
79739538679102 x 1.003 = 79978757000000 kg
Using this speech calculator to calculate the speed of the exact same words in the last scan above, I get a nine-second timeframe.
56327/9 = 6258.55555556 m/s
This gives us 1566364666649600000000 joules, or 374.37014021261950347 gigatons of TNT. High 6-C, Large Island Scale (or Large Island level, on VS Battle Wiki)
This should obviously scale to anyone with more post-nut clarity (guilt) than this random guy, so Afton definitely scales far above him, among many others.
