Pain had just finished blowing up the Hidden Leaf Village, Naruto had come back but was immediately raped.
It seemed as though the village was doomed, until suddenly...A GENERIC NINJA BURST OUT OF THE FILLER USING SHEER CONFIDENCE!
"I will defeat you with all my ninja skills!" yelled the Generic Ninja.
"All I know is pain, get out of my way, I need to get to hot topic before the sale ends." retorted Pain seemingly frustratedly.
They immediately had an epic clash that I will now detail for you.
The Generic Ninja threw a kunai.
Pain noticed the kunai was somehow too fast, but it was too late, and it ripped through all of his bodies.
The Generic Ninja used his ninja info cards he had acquired by wrecking Kabuto, to discern the location of Nagato.
Nagato was so scared by the might of the Generic Ninja that he kirred himself, because it's the only thing he know how to do.
The entire village celebrated the Generic Ninja as their savior.
The tales of the Generic Ninja did not stop there however, his kunai murdered the crap out of Sasuke, thus putting an end to his unlimited edge, and he fucked Sakura endlessly.
The Generic Ninja eventually met his end to a leaf that fell too hard from a tree and hit his shoe, which made him explode into pieces.
After such events everyone forgot about him because he was too generic, so people just made up some story about a guy named Naruto.
Hail Generic Ninja!
