He/She is the ultimate defence when it comes to protecting the Ninja Village..
When the opposition is super strong and cannot be stopped by ordianry ninja or one that will cause huge casualties if fought the Jounins..The hokage comes in and saves the day..
One might say..but she's excellent in Judgement..blah blah...cmon the fact is Hokages arent there for the administration..if it was then the brainiest of the village should be village head..
Hokage is the symbol of the village and the knight in shining armour..he/she is stronger than all if not most and will guarentee the defence of the village..
Shodaime,Hashirama Senju..Inhumanly strong..stronger than Madara..
Nidaime..Mastery over Suuiton based techniques is unmatched till date..
Sandaime,Sarutobi..Knowledge of almost all known jutsu..and at his age to be named hokage..unmatched in his younger days
Yondaime,Minato Namikaze..The ultimate..He stopped the Kyuubi..the unthinkable feat..and was the model Hokage..
Great chakra control..Greatest Medical Nin..Inhuman strength in hand to hand combat..
Now lets look at her enemies..
Madara:has she got a chance in protecting the village against his space time jutsu?
Pein:Jiraiya couldnt do much....
So,is Tsunade below par for the position of Hokage??
