One interesting concept could be alternate endings. Maybe in the fanfiction, the main character finds a different solution to the problems in the original story. Another concept might be character relationships. Fanfiction could explore deeper friendships or rivalries between the characters that weren't fully developed in the original.
In Project Hail Mary fanfiction, a common concept could be the exploration of different planets. Instead of the ones visited in the original story, the fanfiction could take the characters to a whole new and strange planet with unique ecosystems and challenges. This would add a new dimension to the adventure and the overall story.
