*puts on the flame vest*
Firstly, like your choices they make sense.
Secondly...this will be just my opinion...
5. Rock Lee: HARD WORK.....Had no affinity for Shinobi life....sucked it up and became a boss.
4. Jiraiya/Kisame/Shikamaru: Jiraiya put it all on the line just for his student and the world. Jumped right into a hailstorm of OP and honestly dis extremely well. Despite a blown off arm and a pierced throat he gave the hint to defeat Pain. Kisame....a legend. He sacrificed himself just to save Akatsuki's goals and his dream of a world without lies....where he wouldn't have to kill bis Nakama. Shikamaru showed that it isn't always who had the bigger gums, but who's got it up top...until Madara, Pain, Obito....yeahhhh -.-
3. Tobirama/Itachi: Despite a bad choice (killing family) he did it for the village and his Broski. Takes a lot of heart. He even set up bis desth to stone for something he theoretically was in the right for. Tobirams, as we have seen, had SO MANY techniques and a lot of them OP, but he gave it all away to save the next generation.
2. Naruto: Took 12 years of B.S. (though...should've noticed Hinata

), and never gave up on his dreams. Not the brightest, but he's full of confidence and determination.
1. Hinata: *puts on extra flame vest* Firstly, unlike pretty much everyone above...she's not an OP haaxed badass or an extremely smart person. Instead she's got extreme courage. Despite growing up being hated by her father, training hard, but never benefiting, and always failing missions....Hinata still has the courage to fight people leagues ahead of her to protect those around her....willing to sacrifice even her life without hesitation. To be able to do that with courage alone I say bravo.
