Summary

Here I am talking on some calculations, cosmologies and other stuffs related to the Gridman franchise - SSSS.Gridman in particular.

Spoiler alert: Covers core story information.

Episode 1: Ghoulghilas fires a fire ball

SSSS.Gridman - 01 - fireball1calc

Roughly half a school building is being destroyed.
This site says the minimum space area for a secondary school is 3500 sqm.
I see that the hieght of the school is roughly 4 storeys at ~4.42 m per storey. (Since the minimum area refers to the whole school premise, we should not divide it by 4 actually.
Volume of school destroyed = 3500 sqm * 50% * 4.42m * 4 / 4 = 30940 m^3 = 7,735,000,000 cc
90% hollowness assumption means volume of building material destroyed = 773,500,000 cc
Assume reinforced concrete at shear strength 28 J/cc
Energy used = 773,500,000 cc * 28 J/cc = 21,658,000,000 J = 5.1763862332696 ton TNT (Large Building level)

Bear in mind this is one attack from an Episode 1 monster.

Episode 1: Gridman Runs

Gridman runs like a normal human. Except with proportional gigantic size.

By Wikipedia, the average US human stands at 1.6875 m (rounded to 1.69 m) and weights 82.6 kg.

Also, our site says the average "average human" here runs at (5+7.7)/2 = 6.35 m/s, dead lifts an object at (50+800)/2 = 65 kg, has a striking strength of (100+40)/2 = 70 J, but has a running energy of 0.5 * (82.6 kg) * (6.35 m/s)^2 = 1,665.31925 J and combat speed of ~10 m/s.

Using the Ugarik model of fictional giant, our Gridman rising to 70 m tall (this is the official maximum height he can theoretically reach) should be...



Travel speed = 263.4074074 m/s (Subsonic+) (Speed2 = Speed1 * (Height2/Height1))
Attack speed and reactions = 414.8148148 m/s (Supersonic) (Speed2 = Speed1 * (Height2/Height1))

Lifting strength = 192455528.3 kg = 1.924555283 * 10^8 kg (Class M) (LS2 = LS1 * (Height2/Height1)^4)
Striking Strength (standing) = 8597443542 J = 2.054838323 tons of TNT (Large Building level) (Striking Strength 2 = Striking Strength 1 * (Height2/Height1)^5)
Attack Potency with running acceleration = 2.04536E+11 J = 48.88516878 tons of TNT (City Block level) (Running Energy 2 = Running Energy 1 * (Height2/Height1)^5)
Okay we know by now why tokusatsu giants love running around before attacking enemies.

Again this is the lower limit. And applies to all ~70-m tall characters.

Episode 12: True Form Gridman plays Legendary Spyro

Spoilers:
This is the real shown part of the Cyber World, which Alexis Kerib previously destroyed. This Gridman fought with Alexis Kerib right after Alexis Kerib destroyed this Cyber World at the very beginning of Ep 1. And Gridman lost first.

Yep. The "Grid Fixer Punch" caused a cleansing shockwave that recovers the Earth in 5 seconds.

Earth radius = 6371 km = 6371000 m
Half Earth circumference = 2 * pi() * r / 2 km = 20015086.8 m
Shockwave covers Earth in 5 seconds = 4003017.359 m/s = Mach 11773.58047 (~1% Sol, Sub-relativisatic)

Attack Potency ~= Durability ~= 183242.63 Teratons of TNT (Multi-Continent level)

This only applies to True Form Gridman and Full Power Alexis Kerib.
