For some reason...Lee.
The dawg can't do genjutsu or ninjutsu but despite that...he's always determined to prove people wrong that his taijutsu skills are just as good as those who specialized in genjutsu or ninjutsu.
When he was in the hospital in Part 1 after his battle with Gaara, he didn't rest. He did push ups instead even if the nurses told him otherwise! He's a fighter.
