Hello, everyone! I am here to bring you all yet another Mega Man calculation. This time, I'll be revisiting a feat that I previously calced on this website which I'm not too proud of all things considered: Wily Star fuckery!
Premise[]
So as we know, these calculations are what's being used for the Wily Star's feats. However, these 2 have a common problem: it is assuming that the Wily Star is across an asteroid belt. The problem with this is that nothing really claims this to be the case, and unfortunately is deconfirmed by one of Mega Man V's guidebooks which says he's just flying through a Meteorite Zone.
With all this said, I thankfully found 2 other ways of calculating this feat. The following are those methods:
- The Mega Man & Mega Man X Encyclopedia seem to imply that the Wily Star is a planet here. Note that the context surrounding this comment is how the Wily Star was going to have the ability to use fists to fight (which are one of the bosses inside of it) and not about the skill of the mechs. This would also be consistent with Rock confusing the Wily Star for a planet.
- The same guidebook + the Mega Man V guidebook consistently call the Skull Blazer's cannon that shoots that huge laser an Ion Cannon, which according to Wikipedia is one of the many names of particle beam weapons which travel at near-lightspeed.
So! With these 2 points, I shall assume a low-end and high-end for all components of the whole series of events for this blog: a low-end assuming it is the size of the Earth with Point 1 being the main justification, and the high-end will be assuming the laser is a particle beam and then using that to find the size of the Wily Star using Point 2 as main justification. Should not be complicated.
Wily Star Size & Mass[]
Low-End[]
The diameter of the Wily Star will simply be 12,742,000 meters across, which is... planet-sized. As for the mass? I shall assume that the Wily Star is made of aluminum due to how abundant this material is and a standard hollowness of 80%
Volume: 1.08320692e+21 m3
Mass: (2710 kg/m3) * (1.08320692e+21 m3) * (0.2) = 587,098,150,640,000,000,000,000 kg
High-End[]
This is when angular sizing will be used finally. It will be assumed that the near-lightspeed ion cannon beam (assumed to be around 99% c) took 1 second to reach where Rock was.

Distance of Wily Star from planet: 2.9679e+8 m/s * 1 second = 2.9679e+8 meters
Diameter of Wily Star: 2*tan(40deg/2) * 2.9679e+8 meters * 3234px/3603px = 193,919,231.378 meters
Volume: 3.81822279E+24 m3
Mass: 3.81822279E+24 m3 * 2710 kg/m3 * 0.2 = 2069476752180000000000000000 kg
Rock's Reaction Speed & Rush Space Travel Speed[]
I shall calculate the speed of the beam using the same instance where we found the distance of Rock to the Wily Star and using the same timeframe, and then we can find the speed of Rock's reactions to the lasers.
Low-End[]
Distance: 12,742,000 meters * 3603px/[3234*2*tan(70/2)] = 10,136,898 meters
Speed: 10,136,898 / 1 second = 10,136,898 m/s or 0.0338c (Sub-Relativistic)
Space Rush took 75 around seconds, so...
Space Rush Speed: 10,136,898 meters / 75 seconds = 135,158.64 m/s or Mach 394 (Massively Hypersonic)
Now with that, one can calculate Rock's reactions

Rock's height: 1.32 meters
Head height: 0.165 meters
438px = 0.165 meters
57px = 0.0214726 meters
Speed: 0.0214726 meters / 10136898 m/s = 0.0000000021182614 seconds (FTL Reactions)
This ain't calc-stacking since the laser's speed never changes in-game.
High-end[]
This high-end will be much easier to make. Just divide that calculated distance by the speed of the 0.99c laser. Using the same pixelscaled distance above...
Speed: 0.0214726 meters / 2.9679e+8 m/s = 0.0000000000723495 seconds (FTL+ Reactions)
Rush Space Speed: 2.9679e+8 meters / 75 seconds = 3,957,200 m/s or 0.0132c (Sub-Relativistic)
Missiles KE[]
So... this should be straightforward! Just finding the KE of these missiles! Doing both low-ends and high-ends.
I shall first find the mass of these missiles and then assume they move at comparable speeds to that of Rock throughout this series of events.
Low-end[]

Skull Size: 2*tan(40deg/2)*(10,136,898 meters)*807px/3603px = 1,652,761.6 meters
I shall use this official artwork of the Skull Blazer to use Square-Cube Law to find the mass of the missile (using this missile for reference). The missile's diameter is portrayed as more or less the same as the cannon barrel there, so...

549px = 1,652,761.6 meters
84px = 252881.556 meters
Square-Cube Law: (252881.556 meters / 0.52 meters)^3 *1450 kg = 1.667e20 kg
Kinetic Energy: 9.5290784500839E+30 Joules or 363.9 Exatons of TNT (Moon level+)
High-end[]
Same angsizing and pixelscaling...
Skull Size: 2*tan(40deg/2)*(2.9679e+8 meters)*807px/3603px = 48,389,864 meters
549px = 48,389,864 meters
84px = 7,403,914 meters
(7,403,914 meters / 0.52 meters)^3 *1450 kg = 4.185e24 kg
Kinetic Energy: 3.27673611252E+37 Joules or 7.8315 Ronnatons of TNT (Large Planet level)
Rock would scale to these results since he can harm people that can scale to Rush.
Wily Star Shaking[]
I shall now calculate the shaking of the entire Wily Star. To explain what I'm about to do here: as we can see, the distance the battle planet moves relative to its rest position varies quite a bit with its shaking. So what I'm gonna do is find the average distance the Wily Star moved during every motion and then using the average time of each interval, divide the average distance to find average speed. Mass used for both KE is the mass of the entire Wily Star.
Low-end[]

Here is a video showing all the distances moved in a GIF. You can pause it so you can see every single pixelscaling movement.
975px = 1,652,761.6 meters
102px = 172,904.3 meters
102px = 172,904.3 meters
81px = 137,306.3 meters
78px = 132,209.3 meters
57px = 96,623 meters
54px = 91,537.57 meters
Average: 114,082.7 meters
It took 1 whole second for these 6 relevant intervals to happen. So the speed is just this average divided by 1/6 of a second.
Speed: 114,082.7 meters / (1/6) seconds = 684496.2 m/s
Mass: 5.871e23 kg
RKE: 1.3753854647256E+35 Joules or 32.873 Yottatons of TNT (Large Planet level)
High-end[]
Using the same pixelscaling but the high-end dimensions.
975px = 48,389,864 meters
102px = 5,062,324 meters
102px = 5,062,324 meters
81px = 4,020,081 meters
78px = 3,871,189 meters
57px = 2,828,946 meters
54px = 2,680,054 meters
Average: 3,920,820 meters
It took 1 whole second for these 6 relevant intervals to happen. So the speed is just this average divided by 1/6 of a second.
Speed: 3,920,820 meters / (1/6) seconds = 23,524,920 m/s
Mass: 2.0412e27 kg
RKE: 567444197065904668907340056555192075032000 Joules or 135.62 Quettatons of TNT (Small Star level+)
We currently scale people to the shaking in VSBW since this is Sunstar's death throes that are causing this. So...
Wily Star Destruction[]
I shall calculate this by using KE for when the Wily Star explodes and the halves move away from one another. It took at least 1 second for all the material to travel at least the latter distance pixelscaled (logically it would but it's not depicted as such due to graphical limitations).
Low-end[]

459px = 12,742,000 meters
519px = 14,407,620.9 meters
Speed: (14,407,620.9 meters / 2) / 1 second = 7,203,810.45 m/s
RKE: 15240343736910365407200410650978117471 Joules or 3.6425 Ronnatons of TNT (Large Planet level)
High-end[]
Same thing but with high-end measurements...
459px = 193,919,231.378 meters
519px = 219,268,150.512 meters
Speed: (219,268,150.512meters / 2) / 1 second = 109,634,075.256 m/s
RKE: 13653043384500368637103380455699958003015429 Joules or 0.1365 FOE (Large Star level)
BRILLIANT! Gentle reminder that no one scales to these results and only Sunstar with the self-destruct bomb would.
