Not exactly.

You're still new here, right? It's sounds like you kind of understand how different worlds work. Back in my home, there's a lot of techniques people can use to do a bunch of things called jutsu. And one jutsu lets a person make clones of themselves. There are no eggs or anything; they just appear in a puff of smoke. They can move and fight, but if they get hit hard enough, they'll disappear again. Or the one who made them can make them go away when they're done too.
