The Feat[]
In the Season 2 Finale of Helluva Boss, "SINSMAS", Stolas, who just got his demonic power revoked from him, reducing him to but a weak plebeian, goes to his estate to find his long lost daughter, Octavia. However, he is greeted instead by his arch-nemesis, Andre, who taunts him about his lost power, estate, and daughter. This enrages Stolas, provoking him to unleash a brutal beatdown on Andre, culminating in him lifting one of the statues Andre made in the courtyard over his head, before bashing Andre with his own likeness.
The Calculations[]
Part I: Scaling[]
Part I: Statue[]

Behold, the drawings of a madman. As you see, I have tried my best to simplify the statue into calculable shapes, so this is gonna be a very rough approximation. (Also, we're gonna have to divide most of the values to find the radiuses.)
Stolas' height (red line): 550px / 3.34 m
3.34/550 = 0.00607 m/px
Diameter of bottom cone (blue line): 294px
0.00607*294 = 1.785 m
1.785/2 = 0.893 m
Height of bottom cone (green line): 231px
0.00607*231 = 1.402 m
Diameter of top cone (yellow line): 107px
0.00607*107 = 0.649 m
0.649/2 = 0.325 m
Height of top cone (purple line): 108px
0.00607*108 = 0.656 m
Diameter of bottom ellipsoid (orange line): 185px
0.00607*185 = 1.123 m
1.123/2 = 0.562 m
Height of bottom ellipsoid (cyan line): 114px
0.00607*114 = 0.692 m
0.692/2 = 0.346 m
Height of top ellipsoid (magenta line): 61px
0.00607*61 = 0.37 m
0.37/2 = 0.185 m
Diameter of top ellipsoid (lime line): 86px
0.00607*86 = 0.522 m
0.522/2 = 0.261 m
Part II: Andre[]

Since the statues aren't seen from the front, I'm gonna have to get a front-facing picture of this guy and scale from there.
Height of Andre's head (red line): 560px / 0.37 m
0.37/560 = 0.000661 m/px
Width of Andre's head (blue line): 520px
0.000661*520 = 0.344 m
0.344/2 = 0.172 m
Width of Andre's cloak (green line): 996px
0.000661*996 = 0.658 m
0.658/2 = 0.329 m
Part II: Volume[]
pi*(0.893^2)*(1.402/3) = 1.171 cubic meters
pi*(0.325^2)*(0.656/3) = 0.0726 cubic meters
(4/3)*pi*0.562*0.329*0.346 = 0.268 cubic meters
(4/3)*pi*0.261*0.172*0.185 = 0.0348 cubic meters
1.171+0.0726+0.268+0.0348 = 1.546 cubic meters
The density of ice is 0.9167 grams per cubic centimeter, or 916.7 kg per cubic meter.
916.7*1.546 = 1417.218 kilograms (1.417218 metric tons - Class 5)
Part III: Speed[]

Height of Stolas holding the statue: 1126px
0.00607*1126 = 6.835 m
Since he swung it downwards, I'll take this as the radius of a circle, calculate the circumference, and divide it by 4.
2*pi*6.835 = 42.946 m
42.946/4 = 10.737 m
The swing took 13 frames at 60 frames per second.
13/60 = 0.217 sec
10.737/0.217 = 49.476 m/s
Part IV: Final Result (Attack Potency)[]
0.5*1417.218*(49.476)^2 = 1734585.955 joules (1.734585955 megajoules - Wall level)
I'm not gonna be calculating the destruction itself, as that's probably gonna be way lower than the KE, so it'll just be redundant.
Part V: Acceleration[]
The acceleration took 11 frames.
11/60 = 0.183 sec
49.476/0.183 = 270.361 m/s2
Part VI: Final Result (Lifting Strength)[]
1417.218*270.361 = 383160.476 newtons (39.071494955 metric tons - Class 50)
UPDATE: Lifting Strength[]
Just realized I could use centripetal force for the lifting strength, soooo…
(1417.218*(49.476)^2)/6.835 = 507559.899 newtons (51.756705806880007 metric tons-force - Class 100)
Conclusions[]
Somebody really needs to make a Helluva Boss CRT.
