Shikamaru's dad, Ino's dad, and the entire intelligence division as well from the Jyuubi bomb?
Best: Kisame Hoshigaki. It's so mysterious how he's still a shark and he had great commitment to Akatsuki by killing himself.
More: ROOT/Jounin exam and operations.
Worst: Sakura and pretty much every girl in the series was useless to the progression of fights and the story (except for Kaguya, Konan, Tsunade, Naruto's mom, the Third Hokage's wife as a midwife for Naruto's mom, and arguably Karin).
