Greetings, everybody! Migue79 back again to bring you all yet another Mega Man calculation. Today's feat will be this one... Rock literally shooting Dr. Wily down, and the tiny capsule literally causing a huuuuge explosion that can be seen from outer space just by crashing! Wily was in the middle of this, so there's no reason to say that he wasn't caught up in it. And he survived it since he appears in Mega Man 4.
WARNING: Turn your volume down when opening the video because the music is absolutely awful in this game.
Calculation[]

Perceived diameter of Earth: sqrt(1-(tan(35)*(5970/2259))^2/((tan(35)*(5970/2259))^2+1)) * 12742 km = 6057.82 km
5970px = 6057.82 km
366px = 371.4 km
185,700^3*((27136*1.37895+8649)^(1/2)/13568-93/13568)^2 = 514.66 Gigatons (Large Island level+)
Conclusion[]
Mega Man 1-5 Robot Masters will scale to Large Island level+ through Rock literally being able to damage it in the boss fight and by virtue of being physically superior to Dr. Wily (Wily scales because he was caught up in that explosion point-blank, and given his capsule was exploding due to Rock damaging it, it should be in reason that the capsule was destroyed).
