Naruto: Fan Girl Apocalypse
It is bright day in konoha, where everyone in the village was minding their own business, when suddenly they felt tremors. They feel it getting stronger and stronger, until they hear a certain snake pedo say "BWAHAHAHAHA FINALLY I WILL DESTROY THE LEAF VILLAGE WITH THE ULTIMATE WEAPON: FAN GIRLS/BOYS!"
During this announcement all ninjas/kuniochi who had fangirls/boys visibly paled (especially Sasuke, kakashi and kurinai) and started running saying "everyone run for your lives!" At the hokage tower, Tsunade told every able ninja to repel the invaders, but they couldn't hear her over the horde of fans saying "HAVE MY BABIES, MARRY ME, LET ME TOUCH YOU". Slowly but surly Konoha fell to the horde of fangirls, the defenders were overwhelmed, they used every jutsu they knew, but it wasn't working, there seemed to be an infinite amount of fans. Later on the news spread like wildfire saying that Konoha fell to an infinite number of fangirls.
Epilogue
After a few months everybody got defeated including the akatsuki, juubi, and even the snake pedo who unleashed this horror onto the elemental countries in the first place. The moral of the story is "never tickle a sleeping dragon"
