In chapter 158, Sage Centipede goes after Garou and Metal Bat with everything.

Calc[]
Pixels[]
- Crater = 117 px = 2315 m
- 2315/117 = 19.7863247863 m/px
- Sage diameter = 78.5 px = 1553.22 m
- Sage height = 46.7 px = 924.02 m

As mentioned in the chapter, Sage Centipede has 6666 legs, that is, 3333 legs on each side.
- L = (924.02) * (3333)
- L= 3079758.66m
Mass[]
- M = ((1553.22/0.008)^2 * (3079758.66/0.2)) * 0.003
- M = 1.7413815e+15 kg (Class P)
Using this method:

The cross-sectional area of the Millipede is an ellipse.
- I = 0.25(a^2+b^2)m, where a and b are half the axes;
- I = 0.25(((1553.22/2)^2+(924.02/2)^2) * 1.7413815e+15 = 3.5549273e+20
Each rotation = 2 * 3.14 radians;
Angular velocity (w) = 66,6 * 2 * 3,14 = 418,248 R/S;
- E = (3.5549273e+20 * 418.248^2)/2 = 3.1093419e+25 Joules
Final Result[]
- Sage Centipede AP: 7.42 Petatons of TNT (High 6-A, Multi-Continent level)
