Pitou Blasts Off
Pitou uses En, then blasts off to reach Meruem and Komugi. What’s impressive about this feat is that Pitou covers a long distance in a short amount of time. What is the time frame? That’s where it gets complicated. See, the manga gives time frames every once in while during the infiltration of the palace. However, it’s not all in perfect order. Certain events happen at the same time, in particular, Youpi’s encounter with everyone and Pitou falling from the sky. What we know for absolute certain is that this:
Happens as the last of the dragons are striking the palace. When did that happen?
We see that the dragons have officially stopped at 3.28 seconds. This is also stated to be the same time that Pitou reached Meruem.
3.01 seconds is the time frame that comes before, and this is also when the dragons are still raining in throughout the palace. The only time that comes before that is .98 seconds, and that was before the dragons hit the palace.
Therefore, our best lead into the time it took Pitou to jump is .27 seconds.
Alright, well how far did he jump?
Pitou’s En has a range of 2,000 m. It measures 589 pixels here compared to 418 as distance from Pitou to Meruem’s location, 216 for length of the palace and 149 for width. The last two measurements are for a later calculation.
418 / 589 = .71 * 2,000 = 1,420 m, distance traveled by Pitou.
216 / 589 = .367 * 2,000 = 734 m, length of palace.
149 / 589 = .253 * 2,000 = 506 m, width of palace.
1,420 / .27 = 5,259.259 m, or Mach 15.47
Youpi Destroys a Staircase
Youpi smashes a large stone staircase. As we can see below, only 7 stairs remain after the destruction:
Gon is 1.54 m tall. He’s 36 pixels tall here compared to individual stair height of 25 pixels and stairs width of 489.
25 / 36 = .694 * 1.54 = 1.069 m, height of individual stair.
489 / 36 = 13.583 * 1.54 = 20.918 m, width of stairs.
As mentioned earlier, Youpi destroyed the staircase at the 7th stair from the top. From the height of the next stair down, it’s 140 pixels compared to depth of stairs at 147, height of single stair at 11, and depth of single stair at 11.
140 / 11 = 12.727 * 1.069 = 13.605 m, height of destroyed staircase.
147 / 11 = 13.364 * 1.069 = 14.286 m, depth of destroyed staircase.
Depth of a single stair is equal to height, so it’s also 1.069 m.
Treating the staircase as the basic shape of right triangular prism, the volume comes to 2,032.822 m^3. However, we have to account for each stair as well. There are 20 stairs at 23.904 m^3, so it comes to 478.08 m^3.
2,032.822 + 478.08 = 2,510.902 m^3, full volume of destroyed staircase.
2,510.902 m^3 =2,510,902,000 cm^3
There is some debris that shoots away, but at least half of it remains after the initial attack. We’ll do the lower end of explosive fragmentation, 15 J/cc.
2,510,902,000 * 15 = 37,663,530,000 J, or 9.002 Tons of TNT.
Youpi’s Crater
Youpi takes a page out of twitter’s playbook and uses some fake rage to make a large crater in the ground.
As previously established, the width of the palace is 734 m. It measures at 210 pixels here compared to crater diameter at 30.
30 / 210 = .143 * 734 = 104.962 m, diameter of crater.
As a perfect half-sphere, the volume of cratered rock would be 302,736.593 m^3.
302,736.593 m^3 = 302,736,593,000 cm^3.
This is about as obvious as it gets, but I’m using cratering, 87 J/cc here.
302,736,593,000 * 87 = 26,338,083,591,000 J, or 6.295 Kilotons.
Silva’s Dramatic Entrance
Cheetu is harassing an old man in public, so Silva teaches him a lesson that he’ll only have learned for a fraction of a second before he’s dead. But still… learn your place, little ant! 
Zeno is 1.61 m tall. He measures 59 pixels here compared to 220 for depth of crater and 472 for diameter.
220 / 59 = 3.729 * 1.61 = 6.004 m, depth of crater.
472 / 59 = 8 * 1.61 = 12.88 m, diameter of crater.
Clearly this is not your everyday crater. I’m instead going to treat it as a dome, which would give it a volume of 504.46 m^3.
504.46 m^3 = 504,460,000 cm^3.
87 J/cc as this is clearly cratering once again.
504,460,000 * 87 = 43,888,020,000 J, or 10.49 Tons of TNT.
