Yōkai

I know this thread has been dead a while but i just wanted to bring up some info. Anbu are selected, they aren't trained you have to have that knack to be one. Sannin is a title given to the 3 shinobi that took on Hanzo the salamander and held their own. Sannin are powerful in their own right but aren't Jounin, they were genin when they became Sannin. Kage doesn't mean your the strongest shinobi it just means you have the leadership qualities, but of course usually are strong in their own right. Anbu can be genin, jounin, or chunin. They're basically scouts. trackers, assassins. Of course a lot of em die, thats because they aren't major characters in the series. Only time Gai can take Kakashi and win would be if he opened up to maybe 3rd+ lotus gate. In fact i think its been said that hes actually never beaten him in a actual fight and lost to Kakashi twice when they were younger. Every other "fight" has been rock paper scissors, races and the likes. As for Konahamaru being the grandson of the 3rd Hokage doesn't mean much, the 3rd wasn't exceptionally strong but he was really smart and just knew a ton of different jutsu's. For him to take on Itachi would be suicide, he's not as gifted as the rest with the exception of learning the Rasengan at his early age. Remember Itachi was already a ANBU at his age and leader a few years later. Tsunadae is actually a Hokage so shes not Jounin anymore.
