Naruto
I just re-watched Rock Lee vs. Gaara fight. It´s still my favorite fight in Naruto.
the best fight in naruto are
Rock lee vs gaara(still the best fight in the series)
shikamaru vs temari
shikamaru vs hidan(by far the best thing to happen in shippuden plus the anime team went all out and made it better)
shikamaru vs curse seal girl
not much variety in characters
3rd hokage vs orichimaru would be on there if you ignore the multiple episode of sword tug of war
naruto vs sasuke didn't make the list cause of the fight was like 5 episode with the first 3 episode being made up of badly paced crap, retcon flash backs,some long emo/homo conversation with the 4th episode containing the stuff happening.
worst fights in naruto
naruto vs neji(if i had to vote for the worst fight of the entire naruto this would have my vote, get destroyed by genius dude for multiple episode only to make a come back by beating the guy who can see through anything with a single punch from the ground)
naruto vs kakuza(when naruto caught wind of a good arc might actually happen in shippuden, he made haste to show up and ruin it cause he won't allow good arc to happen on his watch)
jiraya vs orachimaru vs tsundae vs kabuto vs naruto also that other useless woman thats with tsunda with pig(don't even remind of that arc dear god it was fucken awful every single thing it was terrible all the fights, also thanks to this arc
I will never be able to take kabuto seriously his a joke that got one hit K.O by kid naruto
