So let’s start with the most popular

EXHIBIT A: Dumbbell (Insane In The Mama Train)

He pulls it off with ease (relaxed pose, no real effort exerted until he makes the effort of hefting it and throwing it). Going off the size of these dumbbells, they are either 45lbs or 100lbs. This is a big gap! But seeing as the yokai falls over as soon as its removed, we can assume that Donnie is AT MOST tossing a 100lb weight with little to no effort.

UNFORTUNATELY this doesn’t tell us much else since we don’t see the weight hitting anyone/anything other than the traincar door before it teleports away.

So! We must delve further

EXHIBIT B: Donnie’s Equipment

We know Donnie’s tech bō is made from high grade titanium.

TITANIUM IS A LIGHT METAL! Revered for being light weight, flexible, and rust-proof. Used to make medical tools! This make perfect sense as 1) ninjas need maximum mobility and heavy equipment is counter intuitive, 2) melee weapons are supposed to be LIGHT (see reason 1).

However! This does not stop me from calculating the weight of Donnie’s tech bō regardless.

TO DO THAT, i must first calculate the length of his staff (operating under the assumption that both the ninpo staff and the tech bō are the same in size).

BŌ STAFFS ideally are the same height as the wielder. We are going to use this image (cannot find source) as reference, just like i did w Raph (give or take any growth between season 3 finale and movie)

Donnie is 5’3”, and while i’m here, weighs ~140lbs give or take after plastron, muscle mass, and Bones

The average bō staff has a circumference of about 1-1 1/8th of an inch depending on the length. I’m leaning more towards the larger because of the tech bōs gadgetry and hammerspace.

NOW to calculate how heavy a 5’3” metal pole that’s 1 1/8 inch in width of titanium.

Thankfully the internet is Insane and literally has a calculator that calculates this exact thing.

I was able to come to the conclusion that his tech bō probably weighs no more than approximately 1 pound.

Not very heavy!

What about his battle shell?

WELL it depends! For ease, I’m going to calculate it like a backpack.

The average public school backpack is 12-20 lbs full (heavy and 5-20% heavier than a child SHOULD be carrying to avoid back and neck strain).

I’m going to use measurements from this Random Backpack Website I Found and calculate it as a Medium Backpack (larger than standard) with a laptop pouch, and some minor adjustments since his shell covers him from neck to ass (roughly 24 inches, his height is in his legs)

It’s harder to calculate the shell because he has Different kinds and they’re made of different materials.

I am going to give all of these a base of 66lbs + whatever equipment they have

His Mango shell is probably largely padding with minimal titanium lining

Ice Maker shell is probably heavier. Spider Shell, Drone Shell, are all made w titanium so. Assuming Donnie makes EVERYTHING out of titanium

TECH BŌ: 5’3”, ~1 lb

BATTLE SHELLS:

- Mango: ~66lbs

- Drone: ~150 lbs (including whatever is powering it)

- Ice Maker: ~200 lbs (including ice)

- Spider Shell: ~150lbs

New approach!

EXHIBIT C: APRIL

WE SEE DONNIE CARRYING/SUPPORTING APRIL A NUMBER OF TIMES. A majority of them i am writing off because he is using his tech to assist.

HE IS just holding her up easily in this shot. After some cursory google searches i determined April O’neil to be ~110lbs soaking wet because she’s 4’8”, petite, and the boys fling her around like she’s made of craft foam.

Conclusion: Donnie can lift/throw a fairly decent 110 pounds, and carry approximately 200lbs

This is a small number after raph’s 20,000 lbs, and i can barely lift an 84lbs dog so I’m not gonna sneeze at it. It does however check out for someone who is physically fit and active (and does backflips and parkour and fights enemies four times his bodyweight)

BUT WAIT!!! PINE!!! WHAT ABOUT…

EXHIBIT D: SUBWAY KRANG (The Movie)

Donnie DOES get bonked pretty hard by a subway car and doesn’t Immediately Die. To determine this I had to calculate the Weight Of A Subway Car and the Breaking Point of Titanium.

Subway car: 82,000lbs empty

119,000lbs full

Because the subway car looks like this

I’m gonna call it full.

Titanium has a tensile strength of 63,000 pounds per square inch.

After determining the size of Donnie’s shell off his body, and how much titanium was used, i cam to the conclusion that…

I CAN’T ACTUALLY CALCULATE it because the shell he was wearing was actually mystic/ninpo made and therefore NOT SOMETHING I CAN CALCULATE! It does explain why Donnie wasn’t Rapidly Dispersed upon being bonked by an INSANE AMOUNT OF FORCE.

This very issue crops up again with the other example of Donnie lifting and slapping down the drill on Shredder in the season finale. That was aided ENTIRELY by ninpo/mystic abilities and therefore incalculable.

My counter to the argument that “their ninpo is gone, it’s not mystic anymore” is that Yes They Could Not Access Their Ninpo, but their ninpo-made weapons were still fully intact, and TECHNICALLY still working, the ability to use them had just been locked away

i also humbly believe that Draxum’s Ooze made the boys’ bones EXTREMELY resilient and capable of absorbing force the same way Captain America’s shield absorbs vibrations — my way of explaining why they sustain little to no injury throughout the series.

That being said, it makes the fact that Donnie couldn’t break open a watermelon AND sprains his ankle pretty badly tripping on a fruit EXTREMELY FUCKING FUNNY TO ME.

TL;DR: Donnie can throw ~110lbs give or take, with a lift/carry of maximum 200lb (maybe a bit more before it hinders his movement speed!)
