Introduction and Feat[]
In an attempt to quickly get Doomsday off of Bizzaro Earth, he slams the monster into another planet, destroying it in the process. But wait, he hits what looks like the Moon, (albeit square), which would explain why the odd-looking inhabitants of the world are gazing up at it. They wouldn't see the destruction of another, far-off planet, but they would see the destruction of their Moon. Also RIP those guys; have fun with no tides and the inevitable rain of Moon-bits.
For posterity's sake I'll be doing two versions of the calc, one treating it as the Moon and the other treating it as another Earth-like planet.

The Calculation[]
I forgot to increase the width of my paintbrush, sorry! This is a bigger picture than I originally thought. If you zoom in you WILL see the blue and red lines for the planet edge and the green and purple for the debris movement distance, though.
Earth-like Planet Version
The planet edge height is 345 pixels and the planet edge length is 142 pixels. Taking the hypotenuse of both of these values gives us the true edge distance of 373.08 pixels. The Earth has a diameter of 12742 kilometers, so when we divide that by 373.08 we find that each pixel is 34.15 kilometers.
The debris traveled downward 183 pixels and to the right 155 pixels. Getting the hypotenuse of these two distances allows us to find that the debris moved 239.82 pixels, or 8189.853 km, away from the starting point.
- Note: I used the piece of debris that I did because it is hard to tell where the planet used to be. That piece seems to come from a place where the cloud is close to the original edge, which is the best way I can tell to see where it originally was. That is why I chose to piece I did.
Assuming that the time it took for the debris to reach that point was 10 seconds, the speed would be 818,985.3 meters per second. If we high ball it to a single second planet bust, this would end up being a speed of 8,189,853 m/s. Keep in mind that this isn't likely, as the Moon is 1.3 light seconds away from Earth, and the population of the planet seem to be reacting to it. But that panel is already weird since it has the planet in-tact and destroyed in the same shot with no dividers, so nothing is out of the question.
For Kinetic Energy we need Speed and mass, and even though we have speed, we need mass. I will not just use the mass of the Earth, as a cube has more volume than a sphere given equal diameters. In fact, the volume of a cubic planet assuming each edge is 12742 kilometers is 2.07x10^12 cubic km, as opposed to Earth's normal 1.08x10^12 cubic km. This volume is 1.917 times more than normal, so it is safe to assume the mass is proportionately more. So we multiply 1.917 by 5.972x10^24 kg (Earth's mass) to get 1.145x10^25 kg.
Now that we have both mass and speed, we can find the result.
Using a fast timeframe of 1 second for the bust, we get the yield of 3.840x10^38 joules.
Using the slower timeframe of 10 seconds, the result is 3.834x10^36 joules.
Moon Version
As stated above, it looks like they crash into the Moon, not another planet, so I will be giving a Moon result as well. This follows the exact same rules as above, just with different numbers plugged in, so buckle up and use the above values to follow along.
This time we have a diameter of 3474 kilometers, so each pixel is only 9.312 km this time. This indicates that the distance traveled by the debris is 2233.204 km this time around. That would make the speed for 10 seconds and 1 second 223,320.4 m/s and 2,233,204 m/s, respectively.
The volume of a cubic Moon would be 4.19x10^10 cubic km given an edge of 3474 km, and that is 1.905 times more volume than the Moon's true 2.2x10^10 cubic km. This would indicate that the total mass of the square Moon is 1.400x10^23 kg, using the value of 7.348x10^22 kg of the normal Moon.
I know that was fast, but I already explained where the numbers came from before; I am just adjusting the inputs. Now for the high and low end.
Time of 1 second KE: 3.491x10^35 joules
Time of 10 second KE: 3.491x10^33 joules
