One example could be Danny suddenly losing his powers in a fanfiction. This would completely change the dynamic of his battles and how he interacts with the ghosts. It's an unexpected turn that can lead to new storylines like him having to rely on his friends and human skills more.
They can also introduce new themes. Say, an unexpected time - travel event occurs in the fanfiction. Danny could end up in the past or future of the Danny Phantom world. This would allow the exploration of different eras of the story's setting, different versions of characters, and how Danny's actions in this new time affect the overall timeline.
One unexpected situation could be Danny revealing his identity to the whole town not by accident but on purpose to gain their trust in a time of great danger. For example, a powerful ghost is threatening to destroy the town and Danny thinks that if the people know who he is, they can work together better to fight the threat.
One aspect that could make it unique is the way it blends different genres. Perhaps it combines horror elements from the Danny Phantom universe with some comical situations in an unexpected way. Also, the fanfiction might introduce new settings or backstories for the characters that are not in the original, making it stand out.
They can also introduce new plot twists. Say Danny finds out he has a long - lost sibling who is also a half - ghost. This completely changes the family dynamic and the story's direction. It allows for exploring new relationships and character growth that might not have been possible without this unexpected situation.

The Box Ghost could be really unexpected. He's usually so focused on his boxes that seeing him at a party would be a shock.
