Sakura (she is no nothing ninja in part 1, doesn't come from special clan or has special kekkei genkei, but turns it all around it become a tier 1 healer with super strength, enough to support Chiyo in the battle to take down an Akatsuki remember, and her fighting style still resembles how ninja battles use to by, with tactics, using traps and trickery.)
Shikamaru (What a ninja should be, tactic driven battles are awesome, he's style of fighting is just like playing chest, carefully maneuverers intill checkmate)
Gai (his goofiness masks the fact that he's one of the most powerful shinobi on the battlefield, and I love it)
Gaara (Ok, who doesn't like Gaara, thats the question)
Part 1 Lee (Part 2 Lee, hasn't done anything really cool)
