First ep of S.P.D., Emperor Gruumm blows up a planet for kicks. I can't find the episode online, but have a gif.
Let it be known that I used every other frame of the scene because I wanted the gif to be small. I'm not manipulating the feat or anything
Anyway, it's pretty obvious that the mass was scattered rather fast. Much of the expansion (that we can see, anyway) was finished within just 7 frames. 29fps is this episode's frame-rate, making the time-frame 7/29ths of a second. Now it looks like much of the mass was scattered at least maybe twice the radius of the planet itself in that time-frame. Somewhat arbitrary, but I didn't feel like meticulously scaling anything. And, I mean...look at that explosion. (Also, the next paragraph will further corroborate a larger distance.)
How big is the planet? Well Mora, 10-year-old Satan that she is, asks why Gruumm is even bothering to attack Earth because it's so comparatively minuscule to their normal targets. So as a major low-end, the radius would be Earth's. Twice that would be the diameter, which is 12742km on average.
12742000/(7/29)=52788285.7m/s
That's relativistic right there. So let's bust out the relativistic KE equation.
E=(mc^2/sqrt(1-(v^2/c^2)))-mc^2
Mass of Earth is 5.972E24kg.
(5.972E24*299792458^2/sqrt(1-(52788285.7^2/299792458^2))-(5.972E24*299792458^2)=8.5e39J
or about 2 tenatons.
Gruumm didn't personally do this, but he ordered his subordinates to do it on a whim, meaning there was no prep for it. Dunno what it does for S.P.D. as of now, but it seems the least it would scale to is Astronema's highly-prepped Dark Specter-busting missile, especially considering Dark Specter's armada will have had superior tech.
