Alright I was cently thinking about this, while I've always liked Kakashi I never though of him as the genius he supposedly was. Thinking this over I ralise I couldn't have been more wrong, Kakashi in fact has accomplished quite a bit in such a short amount of time. Let me get one thing straight first this is not about how strong he is or if he's kage worthy, it's about his "genius" as a shinobi and what he's been able to accomplish.
1. Created chidori at a very young age
2. Became jounin at a very young age(this is debatable though because it was a time of war and they were low on ninja)
3. Unlocked mangekyo sharingan even though he's not an uchiha, and even amount uchiha it is very rare to unlock it
4. Nearly took out all of kakuzus hearts without any prior intel(didn't even use his MS, but did have a small bit oh help)
5. Was seen as a threat even by pain(not really an accomplishment but more of an acknowledgment of his ability)
Alright that's all I could come up with for now, now please add and debate, and of course I can probably expect some flaming sprinkled in for flavor
