Maybe there's a plot twist where Rias discovers Naruto has a hidden power that is related to the Rating Game's magic system. This could lead to a whole new level of cooperation and strategy between them and their teams. For example, Naruto's ability to sense chakra could be translated into sensing the magical energy in the Rating Game, giving them an edge in detecting opponents' moves.
A really interesting plot twist could be that the Rating Game is revealed to be part of a larger, more sinister plot that involves both the Naruto universe and the world of High School DxD (where Rias is from). This would force Naruto and Rias to put aside their differences in game strategies and work together to uncover the truth and save both their worlds.
A possible scenario in this fanfic could be that Rias initially underestimates Naruto. But as the fight progresses, she realizes his true power. Naruto, on the other hand, has to adapt to the rules of the Rating Game which are different from his usual battles in the Naruto universe. He might have to learn on the fly how to deal with things like the game's battlefield, which could be magically created and have its own set of rules and obstacles.
Well, one exciting plot twist could be when a character who was thought to be an ally turns out to be working for the enemy. It completely changes the power dynamics and the relationships between the characters. Another could be when a long - lost technique is suddenly revealed and used in a crucial battle, turning the tide in an unexpected way.
One exciting plot twist could be that Naruto's new bloodline gives him the ability to control time. He could then use this power to go back and prevent some of the tragedies in the Naruto world, like the Uchiha massacre. Another possibility is that the bloodline makes him immune to all genjutsu, which would completely change his battles against opponents like Itachi or Madara.
Well, Naruto's Sage Mode gives him enhanced perception and strength. Rias has strong leadership and strategic abilities. In a Rating Game, Rias could use Naruto in Sage Mode to scout out the enemy's positions and movements accurately. Then, based on Naruto's information, she could formulate a strategy that utilizes both her team's magical abilities and Naruto's combat skills to outmaneuver their opponents.
Naruto would likely do well. His vast combat experience and unique abilities like Rasengan and Chakra control would give him an edge. The Rasengan, for example, is a highly concentrated form of chakra that can cause a lot of damage.
A really exciting plot twist can be when Agunimon turns out to be related to some ancient power in the Naruto world. For example, it could be linked to a long - lost clan's forbidden jutsu. This revelation then leads to a whole new set of challenges and adventures as Naruto and Agunimon have to deal with the implications. The story then delves into exploring this new connection, uncovering secrets about the Naruto world that were previously unknown.
Maybe Naruto beats Neji not just physically but also morally. He could start the fight in his usual brash way but then realizes that Neji's anger towards the main family is deeply rooted in a long - standing injustice. Naruto then decides to use his words to try and convince Neji to let go of his hatred. This could lead to a moment where Neji is so distracted by Naruto's words that he makes a crucial mistake in the fight, allowing Naruto to win. It would add a whole new layer to the typical battle - oriented fanfic.
Well, one possible plot twist could be that Rias discovers a hidden power within Naruto that is related to Ophis. Maybe Naruto has some sort of connection to Ophis' power source that no one expected. Another could be that the fanfic throws in a time - travel element where Rias goes back in time and changes something that affects Naruto's hero journey in relation to Ophis.
One exciting plot twist could be Saitama suddenly losing his one - punch power in the Naruto universe. This would force him to adapt to new ways of fighting, like using chakra. Another could be Naruto learning Saitama's training regime and attempting it, only to find it's way beyond his physical limits. And perhaps the villains from both universes team up, making it extremely difficult for the heroes to combat them.
In a Dragon Ball fanfic where you're reborn, a great plot twist could be related to the Dragon Balls themselves. What if you're reborn as the guardian of the Dragon Balls? You could have the power to control who gets to make wishes and how. Another plot twist could be that you're reborn with the knowledge of all the different forms and techniques in the Dragon Ball universe, but you can't use them until you complete certain quests. And finally, it would be interesting if you're reborn as an android, but not like the ones we know. Instead, you have emotions and a conscience, which goes against what androids are supposed to be in the Dragon Ball world.
