^ Meet Kakko. A Rock Village ninja who may have very well doomed the entire Narutoverse.
Doesn't ring a bell?
^ Kakko is the guy who caused that cave in that trapped Obito under that huge boulder. Plus, he kidnapped Rin.
If it weren't for Kakko....
- Obito would of never met Madara Uchiha or Zetsu, and turned evil.
- Obito probably would of been assassinated by Itachi during the Uchiha massacre seeing how he would not have the "disguise" of Tobi.
- Obito would of never fought Minato Namikaze his sensei.
- Sasuke would not of discovered the Truth about Itachi Uchiha, and probably would of come back to the village after he killed Itachi.
- Obito would not of swayed Nagato to form the Akatsuki into a group of mercenary missing nin.
- Obito would not become the Juubi's Jinchuriki.
^ Kakko really is the undisputed douchebag of the Narutoverse.
Who knew a fodder ninja could bring such misfortune.
