A plot twist could be that the main villain in the fanfiction is actually a character from one universe who has been corrupted by the power of the other. For example, a Naruto character who becomes evil after getting a hold of some Ninja Steel power. Or vice versa, a Power Ranger who is influenced by the dark chakra in the Naruto world.
Maybe the two worlds start to merge in an unexpected way. Things that were separate, like the jutsus and the Ninja Steel powers, start to blend. So a character might find that they can perform a Power Rangers' attack using chakra, or a Naruto technique with the help of Ninja Steel. This would completely change the power dynamics and relationships in the story.
