Calc Promare - Absolute Zero Heat Death Cannon

Krazor X fires the Absolute Zero Heat Death Cannon and freezes a volcano. Said weapon is also designed to work against solar flares.
Finding the scaling is a bit tricky, but there's a way to get an estimate of the power on display here, as we can scale part of the beam to Lio de Galon's "ear", which in turn we can scale from a sedan it dwarved. The average length of a compact sedan is 177.2 inches, or 4.50088m.
50 pixels = 4.50088m
1 pixel = 4.50088m/50 = 0.0900176m
0.0900176m X 25 = 2.25044m
87 pixels = 2.25044m
1 pixel = 2.25044m/87 = 0.0258671264m
0.0258671264m X 1133 = 29.3074542m

Keep in mind too this isn't even the full beam, just what we can scale from. But it's better than nothing, so let's continue on.
10 pixels = 29.3074542m
1 pixel = 29.3074542m/10 = 2.93074542m

It gets even closer to the volcano, but that's the best scale I have to go with.
2.93074542m X 1228 = 3598.95538m

362 pixels = 3598.95538m
1 pixel = 3598.95538m/362 = 9.94186569m
9.94186569m X 396 = 3936.97881m
3936.97881m/2 = 1968.48941m
9.94186569m X 654 = 6501.98016m
6501.98016m/2 = 3250.99008m

Keep in mind that ultimately the volume would be even higher because of all the spikes pointing out. Anyway, volume as an ellipsoid.

V = 4/3πabc
= 4/3 X π X 1968.48941 X 1968.48941 X 3250.99008
= 5.27679739e10m^3

Ice weighs 919kg/m^3 (the ice is a solid, so it would absolutely weigh a lot more than it would as just gas).

E = 5.27679739e10 X 919
= 4.8493768e13kg

A pyroclastic flow (the ashcloud produced by a volcano) is between 400°C to 800°C, so we'll go with a low end and a high end.

All that ash may sound like more of a mess than a real danger, but just consider the sheer destructive power of a pyroclastic flow. This mass of ash, gas and rock fragments can travel at speeds approaching 125 mph (200 kph). And with internal temperatures of 752 to 1,472 degrees F (400 to 800 degrees C), it can pretty much bake anything in its path.

(Low end)
Specific heat of air is 1.005 kilojoules.

E = 4.8493768e13 X 1.005 X 400
= 1.94944947e16 kilojoules
= 1.94944947e19 joules

We'll also add the heat fusion of air/oxygen, that being 13800 joules/kg.

E = 4.8493768e13 X 13800
= 6.69213998e17 joules

Finally, to add both together.

E = 1.94944947e19 + 6.69213998e17
= 2.01637087e19 joules
= 4.8192420411089873511 gigatons

(High end)

E = 4.8493768e13 X 1.005 X 800
= 3.89889895e16 kilojoules
= 3.89889895e19 joules

The heat fusion is still going to be the same from above, so let's add them together.

E = 3.89889895e19 + 6.69213998e17
= 3.96582035e19 joules
= 9.4785381214149140305 gigatons

Final Results
Absolute Zero Heat Death Canon (low end) = >4.819 gigatons
Absolute Zero Heat Death Cannon (high end) = >9.479 gigatons

This is actually pretty accurate compared with the energy of an average solar flare (around 10^20 joules). Lio de Galon withstands the Absolute Zero Heat Death Cannon for almost a minute, and it's Burnish flames overwhelms and disables Krazor X, though it too is destroyed.
