The weakened Gatekeeper uses all the rest of her power to dissipates morticon's dark clouds
Feat (15:20)
Clouds extend all the way to the horizon and It looks like they're Nimbostratus clouds(2000m)
Calculations[]
Water content
Says here it's nearly 1gram per cubic meter for nimbostratus clouds so I'll use 0.75g/m^3 for its density
V = pi(20000)^2(2000)
=2,513,274,122,871.8m^3
Density= 0.00075kg/m^3
Mass of clouds
= 2,513,274,122,871.8m^3*0.00075kg/m^3
= 1,884,955,592.1539kg
Energy needed to dissipate the clouds
Multiply the Mass by 2264705j/kg
1,884,955,592.1539*2264705j/kg
= 4.26886835E+15
