Aren't the Turtles kinda weak?

[Coola Yagami]

Y'know, it seems every other mutant animal, either because the animal is already viscous as is, or in Bebop and Rocksteady's case, they were fighters as humans beforehand, but it always seems most mutants are already dangerous powerhouses, other than the Turtles themselves.

There are so many animals that when mutated use their animalistic abilities, like having sharp claws, sharp teeth, in the case of mutant birds, the ability to fly, and so forth. But the Turtles themselves are basically just green humans with shells. I guess the only 'extra powers' they get is their shell can protect them from impact that would normally break an ordinary person's back. Though I guess they'd also be natural born swimmers.

Like for example, Groundchuck and Dirtbag can already mess ish up, hell, Slash, a fellow turtle is a lethal powerhouse... but the Turtles ONLY get by because they were trained in Ninjitsu. Like if the Turtles belonged to some ordinary guy that did not happen to be a ninja master... they'd be weak as all hell.

It just seemed the Turtles had to train for years to learn to fight while someone like Leatherhead was already a threat since day one.
