Based on what you said the same could be said for Mitsuki just a couple of key differences
1. Both born out of tubes Mitsuki being the sixth attempt while Yamato was the 100th attempt
2.Orochimaru being alive telling Mitsuki he is his parent while Hashi who is obviously dead cant tell Yamato the same thing let alone knew of his existence or experiments conducted with his DNA
Other than that Mitsuki and Yamato have similar backgrounds
Nice theory.
You cannot compare Mitsuki and Yamato. Two different cases. Mitsuki was born in an artificial womb, fertilized(supposedly) by orochimarus sperm. And Yamato...was already born through his natural birth parents, before he was experimented on. Cannot compare.
He already had a father and a mother, before someone elses DNA was "added" through experimentation.Nothing legitimate. As far as mistuki, sure orochimaru is his legitimate father...that is IF he was produced by his
natural sperm.
