Which battles did you want to see in the manga but never happened or were never shown?
Sasuke vs Neji - Rookies of the Year, geniuses and doujutsu wielders. The possibility was hinted at during the Chuunin Exams but never came about.
Team Kakashi vs Team Gai - An alternativee to the above. These two teams are like reflections of each other and their teachers are eternal rivals. Maybe it could have gone down in the Forest of Death in Part 1, or a sparring match in Part 2. Bonus points if Kakashi and Gai fought one another too.
Sakura vs Kabuto - Medic vs medic. Something for her to do during the Sasuke and Sai Arc.
Haku vs Sasuke - Wind against lightning, water against fire and bloodline limit against bloodline limit. Godly potential for both. Why'd you have to die, man?
Team Seven vs Team Taka - Hinted at during the Itachi Pursuit Arc but never came about and is another example of two teams mirroring one another.
Konan vs Sakura, Ino & Hinata - I think this was in an anime opening. It would have been nice for Konan to have a fight before getting murdered by Obito.
Tsunade vs Pain - Because what actually happened was kind of sad.
Kakashi & Gai vs Seven Swordsmen - Just to see it all go down.
Kakashi vs Edo Sakumo - If only they hadn't had the talk during the Invasion of Pain Arc that made this unnecessary.
Naruto vs Edo Jiraiya - Just 'cause.
Konoha 12 (w/o Naruto) vs Sasuke - Considering these guys had all decided to off Sasuke themselves for the greater good, it would have been nice if they've done something about it instead of Sakura by herself. Or if Sasuke hadn't swapped sides during the Fourth Shinobi War and fought them before Naruto.
