No, their powers are from Devil fruits, they're similar because it's based on some traditional japanese mith or creature with a power like that and since they're Samurais from Wano ("Japan") it only makes more sense for it to be like that with themes.

The tin can soldiers were what had me thinking more than anything I really want to know more about them other than they're powered by spining keys on their back. I wonder if Doffy can make them spin with strings from far away.

Zoro just seems he is stronger than we think (at least it is what the manga is making us think).

It's one of the best chaps since Oda's operation, really like the fact that Kanjuro's drawing skills sucks and they're needed to be good for using the max potential of its power.
