This is a OC SI/Self Insert where the person is not in fact reborn as some random side character; open to be preyed upon by outside evil forces; but as one of the potentially evil forces right from the get go: Orochimaru. Naori Uchiha is one of the pairing but isn't available in characters. Orochimaru/Naori/Tsunade/Mei only.

What happens when a skilled man is reborn in konoha? Will he be named a prodigy and savior, or will he be shunned for his ability? Will his actions help or harm the timeline? Only one thing is for certain; That things in konoha will never be the same... OC SI

What happens when someone destined for death is instead given a second chance? What happens when a thinker is thrown into a world of violence? What happens when hatred isn't just a temporary and petty feeling, but an inevitable destiny? It's time to make ripples, whether I want to... or not. OC Male Self-insert

Being Re-posted under new name : A World Full Of Monsters

I'm Kiyoshi Yukimura, jounin of Konohagakure, except I'm not. I'm Katsu Yoshida, high school second year, except I'm not. I'm kind of both. It gets a little complicated then. Maybe I should explain. (OC-reincarnates-as-OC!fic. Male!OC.)

Imagine dying then not remembering it, waking up in a cold dark prison and not having a clue what is going on... You have a weird unexplained power that gives you control over your own bones and then you are introduced into the world of ninjas, wars and elemental nations. Then to top it off you meet a pale creepy man that offers to help you get stronger... Self-insert OC.

Orochimaru finds a different way to gain a body with the Sharingan. It doesn't turn out the way he expected. [Self-Insert fic, cross-posted from AO3.]

SI/OC with 'Gamer' powers. Kensuke was sold to Konoha to become a ninja in the aftermath of the Kyuubi attack. He doesn't want to be a ninja, he has dreams of a far more peaceful life in his past, but failing the Academy has dire consequences. It doesn't help that Uzumaki keeps humiliating him with pranks to lighten him up. If only the Sandaime's pet would leave him alone...

"Mako was born a coward, bathed in the blood of another, and yet still wanting to run forwards." A boy finds himself reborn in a doomed village, half-brother and protector of Kushina Uzumaki. He must find out what to do next, in order to survive. Male SI-OC.

Fleeting memories and static interference. Familiar and completely foreign experiences. Why do some things feel so right and others so wrong? Who was I? And who am I going to be? I'm not sure, and hopefully this crazy place doesn't kill me before I find out. Rated T Self-Insert

I wasn't some ditzy prepubescent fan girl whining over an Uchiha, or interested in cozying up with the blond brat. I was a boxer, a guy who liked a cold one and played in snooker tournaments, who briefly got stuck watching some anime with my friend's little girl. Couple months later, I miss my step and become KIA. Guess where I get reborn? Wait, where the hell did my dick go!

They say that the type of Ninja that's fighting style focus' almost only on punching things in the face isn't very lady like. The reason I don't care very much, is that I was not always a 'girl'. SI OC self-gender bent.

Being reborn into the world of Naruto was not how I imagined to spend my afterlife. Though I knew that everything would end with a happy ending, I was worried if I would live long enough to see that happy ending. When your best friends are Itachi and Shisui, you have quite a lot of reasons to doubt. Rated T for language and violence.

I did not die, just to be reborn as a pink little menace whose job is to fangirl over some emo what's-his-name unable pull himself together. (OC-reincarnates-as-Sakura, gender dysphoria)

Reincarnation would be infinitely easier…If he wasn't one of the largest villains in the universe he'd been reborn into. Now, all Madara has is his future knowledge, and stupid pinwheel eyes. Oh, and genetic insanity from his bloodline. Wonderful. (Male Self Insert as Madara Uchiha, slow build).

I died, but I didn't exactly expect to get reincarnated. Especially not as a fictional character who dies younger than I did in my past life. That needs to change. And it will. I'll make sure of it. SIOC Hiatus until I figure out where the heck I'm taking this...

THE REMASTERED VERSION IS UP! GO CHECK IT OUT YOU LITTLE READER YOU!

When I was first reincarnated I did the very first thing any self-respecting man in my place would do. Check to see if I still had my balls. I did. The next thing I did was try to get my hands on some power. True Power. I chose the Rinnegan. And if I had to kill a few people along the way to get it, well, there was a war going on. No one will notice an extra body or two turning up.

In his past life, he was an army man. Even after the war ended, he still craved that rush, the adrenaline. He craved it. In his final breaths, he prayed to what ever God that chose to listen to his pleas. His prayers were answered. He was reborn in Naruto, but not in Konoha. Kirigakure. He could only hope for the best. It didn't help that he had what they hated. A Kekkei Genkai.

A perfectly reasonable man negotiates with god to get reincarnated into the Naruto universe. Not. Male SI, slightly insane SI, Gary-Stu-Wannabe SI.
