It would also be a great opportunity for character development as he learns to be strong without his powers. Additionally, what if the time travel was actually set up by an unknown force within the Naruto universe, and Naruto and Gaara have to figure out who or what is behind it while dealing with the Chunin Exams situation.
A cool plot twist could be that when they travel back, they find out that someone else from the future has also come back and is actually causing more chaos.

This would make their mission to stop Orochimaru or any other threats much more difficult as they have to adapt to this new and unfamiliar situation.
The plot could focus on Naruto's growth. He might enter the fight with Gaara with a newfound confidence. Since he's faced many challenges leading up to the Chunin Exams, he could use his experiences to outwit Gaara. For instance, he could use his quick thinking and agility to dodge Gaara's sand attacks and find an opening to strike.
Well, a great plot twist might be if the Chunin Exams were revealed to be a front for something else entirely. Like, the real purpose was to test the loyalty of the villages to the Hidden Leaf.

Or perhaps a character who was thought to be weak turns out to be a super - powerful ninja in disguise, and they start to turn the tables in the exams.
One popular plot twist could be Gaara suddenly showing mercy during a fight against Naruto in the Chunin Exams. Maybe he realizes they're more alike than he thought.

This would add a whole new layer of complexity to the story as Naruto has to not only deal with his opponents in the exams but also figure out what his Zanpakuto wants.

Along the way, they face many challenges and learn more about each other's families and pasts.
In the fanfiction, a plot twist could be that there is a hidden rule in the Chunin Exams that only Naruto and Tenten figure out.

One possible plot twist could be that Mei is secretly working with an enemy ninja clan during the Chunin Exams. She acts as if she's just a normal participant, but in reality, she's gathering information for the other clan.
