Naruto gets his hands on the key to his seal too early, and the yang and yin chakra of Kyuubi are freed. As in, now there are three Narutos.

“Oh my god, Obito, I don’t care that you keep turning our roommates into mindless zombies devoted to serving your will, but in the name of everything holy, at least stop putting them in thrall when you're singing Taylor Swift songs in the shower.”

For an anon prompt on my Tumblr that I kind of hijacked: gai/obito tho, kakashi's utterly terrified of the two ever coming together. "I've met Gai, Kakashi, and guess what? I'm going /to befriend him/." "You wouldn't DARE, Obito." "Oh, I would. We're going to be best friends." Obito and Gai hit it off instantly, and it all goes downhill from there. Kakashi finds them making out once and it's so horrible. He's never going to get that image out of his mind.

“It was science,” Tobirama huffs, turning his glare on Madara. “You left your DNA all over me, Uchiha. I was hardly about to pass up the opportunity.” Obito debates clamping his hands over his ears and humming loudly. He did not need to know that in any shape or form, oh god.

Aka everyone is a superhero or a sidekick or a damsel in distress in true comic style. Includes terrible hero names, almost everyone wearing spandex (Sakumo why must you be sensible and break the mold you nerd), ridiculousness, secret identity fails, and all of my favorite crack pairings. I would be sorry, but that would require a sense of shame and I misplaced mine long ago.

The best revenge is living well. And maybe also spitefully staging a minor political coup to take over Konoha as payback for getting stuck in an arranged marriage.
