Yes, perhaps Pakura is not actually dead as everyone thought, and she returns when Naruto is in a great crisis, revealing their relationship and using her powers to help him. This would be a huge plot twist as it would change the whole dynamic of Naruto's situation and the relationships he has with other characters.
There could be. Maybe Naruto discovers he's Pakura's son in a very unexpected way, like during a battle when some hidden power emerges and a clue is revealed.
Well, in this fanfiction, a really interesting plot twist could be that Ozai was actually trying to protect Naruto all along, but due to some misunderstandings and the complex politics of the combined universes, it seemed like he was a bad guy. This would completely change the way Naruto views his father - son relationship. Also, it could be that Naruto has the ability to combine his ninja jutsu with Ozai's fire - bending in a way that no one expected, and this new power is the key to saving both the Naruto world and the Avatar world from a greater threat.
Yes, there could be. For example, Naruto might discover his true parentage in a very unexpected way, like during a battle or a dangerous mission.
There might be plot twists like Naruto thinking he is the son of Bane, but then finding out it was all a ruse by an enemy to manipulate him. Another could be that Bane's true identity is not what it seems and his relation to Naruto is part of a much larger conspiracy involving different ninja clans. Also, it could be that Naruto's newfound relation to Bane leads to a split in the ninja village, with some believing he is a threat and others believing he is the key to a new era.

It depends on the specific fanfiction. But it could have a plot twist where Naruto's connection to the Great Red is initially hidden and then suddenly revealed, shocking everyone in the Hidden Leaf Village.
Yes, there could be some interesting plot twists. Maybe the fanfiction has a twist where Kushina was actually being controlled by an ancient evil entity, and Naruto has to find a way to free her.

I'm not sure specifically as there could be many different takes on it. It might be about Naruto having some sort of connection to Pakura, perhaps in an alternate universe where Naruto is her son.

A great plot twist could be that Serafall's enemies target Naruto because of his relation to her.

Another plot twist might be that Naruto discovers some long - hidden secrets about his real father, which could completely change his perception of himself and his place in the world. There could also be a plot twist where Naruto's presence in Serafall's world causes political unrest or changes in the power dynamics of the devil realm.
