I thought it would be a cool to expand upon the snake's genetic experiments on people in the village and try to present some further reaching results.

Tenzo/Yamato is the only survivor/success of the Mokuton experiment, but we know he did other experiments on Konoha citizens and prisoners before his defection despite not knowing exactly what said experiments were.

So I figured it be cool to take a few characters in the village with distinct traits and make them survivors or the children of survivors of some of those experiments. Two easy characters I thought of would be the fathers of Kurenai and Sakura, the 2 of them being direct subjects of experiments.

The Yuhi's have their signature permanent red eyes, which could have been an attempt to replicate the Sharingan or just develop a doujutsu in general, that only resulted in the unique eye pigmentation. And with the Harunos...well their pink hair is pretty unique. I've seen many fics point out Sakura's hair with no followthrough, and i can count on one hand the number of fics I've read where Sakura is made interesting by either being a Senju descendant, or has a kekkei genkai. Apart from the pink hair, her 2nd personality is also an interesting subject with plenty of potential.

I've got a few others in mind, but wanted to see if anyone had any other characters in mind that could also be aftermaths of Orochimaru's work in Konoha, and how.
