One of the most common tropes is the 'fish - out - of - water' story. For example, when a character from Earth is suddenly thrust into the strange and often dangerous world of the Stargate planets. It creates a lot of opportunity for character growth and discovery.
The 'team - in - peril' trope is also popular. In many fanfics, the Stargate team gets into situations where they are surrounded by enemies or in a life - threatening situation. This adds a lot of tension and action to the story. A good example would be a fanfic where they are trapped in a Goa'uld stronghold with no way out.
One popular trope is the 'fish out of water' situation. For instance, a Hogwarts student suddenly finding themselves in the middle of a Stargate base surrounded by Goa'uld threats. Another is the power exchange trope, like a Goa'uld getting access to magic and how that changes the power dynamics.
I think 'Stargate SG - 1: A Matter of Honor' is quite popular. It likely has engaging storylines that fans of the Stargate franchise love. It probably has a good mix of action, adventure and character development.
The trope of alternate universes is also quite popular. In these fanfics, the world of the Stormlight Archive could be completely different. Maybe the Voidbringers are the heroes and the Knights Radiant are the villains. It gives a fresh perspective on the existing characters and the overall lore of the series. It also allows for a great deal of creativity on the part of the fanfic authors.
One popular trope is 'Ahsoka as a Mentor'. In many fanfics, she takes on the role of guiding a young, inexperienced character. It's a great way to show her growth and wisdom.
A common trope in 'Konan Naruto Fanfic' is the 'Power - Up' trope. For example, Konan might gain new abilities or Naruto might learn to use his powers in a new way because of their interaction. There's also the 'Alliance Against a Greater Evil' trope. They join forces to fight a powerful enemy that neither could face alone. And the 'Character Exploration' trope is popular. Fanfics use their relationship to explore the deeper aspects of Konan and Naruto's characters, like Konan's loyalty and Naruto's determination.
One common trope is the 'Forced Proximity'. This is where Hermione and Bellatrix are put in a situation where they have to be close to each other, like when Hermione is captured by Bellatrix. It creates a lot of tension and interesting dynamics between the two characters.
One popular trope is the 'enemies - to - friends' or 'enemies - to - lovers' trope. Since they come from different backgrounds and might initially have different goals, this transformation in their relationship can be really engaging.
One popular trope is the 'Power Struggle' trope. In many Hope Mikaelson fanfics, Hope is often in the middle of a power struggle, either within her family or against external forces. This adds a lot of drama and action to the story.
The 'Search for the Vanished' is also a common trope. Characters in the fanfics try to find a way to reverse the Snap and bring back their vanished friends and loved ones. This often leads to epic adventures and new alliances. It gives the writers a chance to explore different magical or scientific solutions.
One popular trope is the 'lost heir' trope. In many fanfics, a character is revealed to be the long - lost heir to a great house or even the Iron Throne. This adds an element of mystery and drama. Another is the 'undercover hero' trope, where a character pretends to be someone they're not in order to achieve a greater good. For example, a spy within a rival house.
