Minato might also be a prominent character. As their teacher, he can influence the way Obito and Kakashi interact. In some fan fictions, he could be the one to help them resolve their differences or provide some crucial information about their past that changes their current situation.
Some fanfictions might explore the emotional aspect of their fight. For example, how their past friendship affects the battle. Maybe Kakashi hesitates to strike a fatal blow because of their shared history.
The rivalry is the most key element. It's what drives the plot in most of these fanfics. Their different fighting styles, like Sakura's brute strength combined with medical ninjutsu and Ino's mind - control jutsu, also play a big role.
A common theme is competition. Since they are rivals, many fanfictions focus on them competing in various aspects like ninja skills, popularity, or even in getting a guy's attention.
In some fan fictions, there might be a plot where Obito has a change of heart before a major battle with Kakashi. He could start to question his motives and the path he has chosen, leading to a very intense and emotional confrontation with Kakashi that is more about ideology than pure combat.

Sakura's main strength is her physical power. Thanks to Tsunade's training, she has incredible strength that can shatter the ground. She also has medical ninjutsu skills, which can be useful in both saving lives and in combat. For example, she can heal her own wounds or use chakra - enhanced punches. Ino, in contrast, is strong in mind - control techniques. She can enter someone's mind and manipulate them. This is a very unique ability in the Naruto universe.
One popular sakura vs ino fanfic is 'The Rivalry Renewed'. It focuses on their ongoing competition in a new ninja mission context. The story really delves into their characters, showing Sakura's determination and Ino's strategic thinking.
In my opinion, Sakura would win. Sakura has shown great strength and combat skills. She was trained by Tsunade, one of the Sannin. She has superhuman strength which can cause massive damage. Ino, on the other hand, is mainly a mind - control type ninja. If Sakura can resist Ino's mind - control jutsu, which she likely can with her training, she can easily overpower Ino in a physical fight.
In a fanfiction scenario of Sakura vs Ino in the Chunin Exams, it's really hard to say who would win. Sakura has shown great growth in her skills, especially in her medical ninjutsu and strength. However, Ino is no slouch either with her mind - transfer jutsu. If the fight is more about physical combat, Sakura might have the upper hand with her enhanced strength. But if Ino can get close enough to use her mind - transfer, she could potentially take over Sakura's body and win the fight.
