Turtles are stronger than the fandom thinks
Screenshots of a moment when each turtle proved to be stronger than it looks, even without taking their power-up weapons into account.
He can carry Raph on his shoulders, which would mean lifting between 198 and 220 pounds (my estimate of Raph's weight).
He is the one who displays the least amount of strength in the series, since almost all of it is attributed to his weapon.
He can pick up a disc weighing probably between 33 and 44 pounds and throw it like a boomerang, with such force that it reaches the other side of the train car.
There are more scenes in the series that showcase his strength, but like Mikey, he pales in comparison when using his technology.
In this scene, he manages to send the entire league of mutants flying—six in total. I can't calculate exactly how much they weigh, but it's more than in the cases I mentioned earlier.
He's the brother who displays the most strength throughout the entire series.
He manages to dodge an attack without even flinching or bracing himself for it. He also lands blows so powerful that they generate shockwaves, knocking the mutant unconscious.
While he doesn't display his strength as often as Raph, his displays of power are surprisingly unexpected when they do occur.
Usually, in a series dominated by magic, we tend to overlook these moments. Spider-Man has super strength, but this is overlooked in a world with so many superhumans—the same thing happens here.
Interestingly, there are moments when it seems like the turtles aren’t capable of these feats. My guess is that when they’re under pressure, that’s when they tap into that inner strength they possess—probably from their Lou Jitsu DNA. This is something that happens with Splinter, too.
