Busou Renkin - Clash at the graveyard

Introduction

Feat in Question.

Calc

Captain Bravo is 1.85 m.

He is 110 px.

1.85/110 = 0.01681818182 m/px.

Diameter of crater = 319 px = 5.365 meters.

Radius of crater = 2.6825 meters.

The crater looks like a half sphere, so by plugging it into this:

Volume of crater = 80.855171238088 m^3 = 80855171.238088 cm^3.

This is obviously fragmentation, so...

E = 80855171.238088*8 = 646841369.9 Joules = 0.1545987977772 (Small Building level)

Conclusion

Clash at the graveyard = 0.1545987977772 (Small Building level)
