Calc GaoGaiGar - King J-Der destroys Ganymede

King J-Der destroys the Moon Primeval which trapped GGG in a Klein Space, thus freeing everyone. Though we obviously cannot get the energy to destroy the Klein Space, we can infact find the energy to destroy the moon which sustained it. Thanks the the GaoGaiGar Degenki Data Collection, we can confirm that this moon was Ganymede.

31 PRIMEVAL SPECIES
ZX-17 Lung Progenitor
A progenitor that fused with Ganymede, the third moon of Jupiter, and faced the final battle on Jupiter. A curved hyperspace Klein Space was formed, trapping J-Der and the GGG fleet inside it.

The moon has been distorted, but it's 'head' should still be similar in size to how it was originally (it's the only thing we have to scale off). Ganymede has a radius of 2631km (and thus a diameter of 5262km) and a mass of 1.4819e23kg. It cuts away before we can see it fully dispersed, but we can get around this by measuring the time until the Klein Space it was sustaining vanished (and Swan mentions as such).
592 pixels = 5262km
1 pixel = 5262km/592 = 8.88851351km
8.88851351km X 437 = 3884.2804km
Timeframe is 4 seconds and 1 frame (with a framerate of 30 frames per second).

T = 1s/30
= 33.3333333ms + 4s
= 4.03333333s

T = 3884.2804km/4.03333333s
= 963044.728m/s

KE = (0.5)mv^2
= (0.5) X 1.4819e23 X 963044.728^2
= 6.87197892e34 joules
= 16.42442380497131893 yottatons

As it cuts away, let's also get another timeframe of the individual segments scattering.
The timeframe is 1 second and 2 frames.

T = 33.3333333ms X 2
= 66.6666666ms + 1s
= 1.06666667s

592 pixels = 5262km
1 pixel = 5262km/592 = 8.88851351km
8.88851351km X 34 = 302.209459km

T = 302.209459km/1.06666667s
= 283321.367m/s

KE = (0.5)mv^2
= (0.5) X 1.4819e23 X 283321.367^2
= 5.94767952e33 joules
= 1.4215295219885277778 yottatons

To add onto this, I believe I have found another way to directly scale the size of Ganymede from Glorious GaoGaiGar Generation, which has the Earth, Moon and Jupiter to scale with the different Lunar Machine Primevals (which seem to have grown in many cases).
The smallest circle reads 'Moon,' the middle circle reads 'Earth' and the part of the large circle we can see reads 'Jupiter.' The diameter of the Earth is 12756.2km.
102 pixels = 12756.2km
1 pixel = 12756.2km/102 = 125.060784km
125.060784km X 75 = 9379.5588km

Reusing the same scaling as above...

(High end - First method)

592 pixels = 9379.5588km
1 pixel = 9379.5588km/592 = 15.8438493km
15.8438493km X 437 = 6923.76214km

T = 6923.76214km/4.03333333s
= 1716635.24m/s

The mass looks greater, but just to be sure we'll stick with the mass of Ganymede.

KE = (0.5)mv^2
= (0.5) X 1.4819e23 X 1716635.24^2
= 2.18345854e35 joules
= 52.185911567877624861 yottatons

(Low end - Second method)

592 pixels = 9379.5588km
1 pixel = 9379.5588km/592 = 15.8438493km
15.8438493km X 34 = 538.690876km

T = 538.690876km/1.06666667s
= 505022.695m/s

KE = (0.5)mv^2
= (0.5) X 1.4819e23 X 505022.695^2
= 1.88977758e34 joules
= 4.5166768164435948663 yottatons

Final Results
King J-Der destroys Ganymede (low low end) = 1.422 yottatons
King J-Der destroys Ganymede (high low end) = 4.517 yottatons
King J-Der destroys Ganymede (low high end) = 16.424 yottatons
King J-Der destroys Ganymede (high high end) = 52.186 yottatons

This was done without ZA POWAH, so it stands as an important point of scaling, as GaoFighGar with Replica Goldion Hammer (which would be equal to the real deal) was gradually overwhelming J-Quarth, as well as the Replica Brave Robos being able to temporarily block Goldion Hammer (but not as well as J-Quarth did), as well as Replica GaoGaiGar destroying the Goldion Hammer, but loosing the GaoFighGars Hell and Heaven, and Palparepa Plus later matching GaoFighGar's Hell and Heaven...
