Sigh, just wait. From what I get, we are going to see a younger Nawaki very soon. I doubt he is an Oro experiment, since there's already Mitsuki walking around. But I'm almost certain that his hair is purposely like that to look like a mix of Naruto and Sasuke. Also, there is artwork showing Boruto with Kurama Chakra Mode and I'm certain it's going to be that way. If Naruto is dead in the future, someone gotta be the next jinchuuriki and who else would be a more fitting candidate than Naruto's son. EDIT: Sarada is also seemingly shown with Mangekyou Sharingan, I take that to mean that Sasuke/Sakura's deaths will trigger that.

So Nawaki is someone strong enough to kill Naruto and Sasuke (possibly Sakura too) and since parents of two members of the team will get killed, I wouldn't be surprised if Kawaki killed Oro too.
