Actually its not a blood line its simply a unique ability that he had. A blood line is a technique that can be passed on to your descendants which is where the term blood line comes in. Its hereditary and can be passed on to anyone in your lineage.
@ DarthEnder: Its really sad that you watch the show yet you understand nothing. The sand village elders said that they made Gaara the kazekage solely because that allowed them to monitor him and control and limit his activities.
Like I said before other things affect the position of hakage such as the availability of ninja or their willingness to become hokage. Despite what you think of Jiraiya and the guise he operates under we've seen that he is a very capable ninja and has excellent leadership abilities, all the sannin do because they all lead ninjas or squads before they left the village. Don't forget that Jiraiya is the one who trained and taught the fourth hokage in the first place so despite his appearance, you shouldn't underestimate him. Anyway to my point they asked Jiraiya to be the hokage because at that point there was no one else in the village they felt could adequately fill the position.
If Tsunade was there I'm sure they would have asked her instead of Jiraiya that doesn't mean that she is stronger than Jiraiya. Two, the hokage doesn't have to be the strongest ninja in the village simply because that ninja such as in Oro's case could be deemed unfit to fill the position or in Jiraiya's case is not willing to accept the position because as we've seen with Tsunade being Hokage although it gives you some power it severely limits your activities and what you can and can't do. For example because Tsunade is hokage she has to remain in the village at all times except for a few special situations and she can't or atleast she shouldn't engage in activities like drinking and gambling.
As it was mentioned above the previous hokages usually choose who the next hokage will be not solely because of their strength but because of who they feel will be best fit for the position and who will guide the leaf in the direction they want it to go. Like when the first and second decided Sarutobi would be the third hokage, he certainly wasn't the strongest ninja then but they saw qualities in him that they admired and felt would allow him to become a great hokage, much like Tsunade presently sees Naruto.
@ Yukimura as I've said before I try to reiterate myself as much as possible in my posts just for those people who have difficulty understanding me. Yet no matter how many times I repeat myself or rephrase my statements some people still don't understand.
I love you guys, my big unhappy, dysfunctional Naruto family.![]()
Typing that felt disgusting.
