So you wouldn't want Naruto's kid to inheret the Byakugan because it would make him too powerful? I understand your p.o.v. but it wouldn't make him invincible. If the rinnegan was not unstopable and the sharingan has been defeated, adding the ability to see chakra networks would only be a slight advantage for someone who uses power attacks like Naruto uses the rasengan. imo naruto doesnt have the chakra control to utilize the byakugan, but I also like to fantisize that a naruhina baby would have a completely new and unique kekkei genkai and perhaps a unique dojustu as well. Afterall, how many characters have blue eyes?
