[Victim of Fate]

1.Ninja theory

as you commonly see in movies, a large force of ninjas is often defeated by a small, unskilled, pitiful force of "good guys". While contrary to modern military tactics, the large ninja task force is almost always routed. but, if a single ninja attcks, then the the "good guys" usually have a hard time defeating it.

this has prompted "inverse ninja theory"

basicaly the theory stetes that the effectiveness of ninja(s) is an inverse proportion to the number of ninjas present. some sort of mystical ninja "force" that all ninjas can tap into. and, like any power source , energy is going to be strained depending on the number of souces draining off of it.

therefore the ninja "force" is devided equally between all ninjas
this is also accountable for the phenomenon of ninjas getting harder and harder to kill as the battle wears on(less ninjas to drain "force")

2.Naruto is awesome
