This is kinda farfetched, but what if Black Zetsu made Kawaki. Before Naruto chucked him into the Devastation, he said something along the lines of I will get revenge. If he was serious about this, he could've found a way to get back to their universe. Black Zetsu is pretty powerful and resourceful, so he might've made him from DNA of powerful ninjas. He has been shown to manipulate powerful ninjas before, so he could manipulate a ninja like Kabuto.

This is just something that I thought sounded good.
