Well, 'sga crossover fanfiction' typically involves taking the Stargate Atlantis (SGA) universe and crossing it over with elements from other shows, movies, or even books. It's a creative way for fans to blend different fictional worlds together. For example, someone might write a story where the characters from SGA meet characters from Star Trek. It can lead to really interesting and unique storylines.
One common theme is the clash of different cultures. The Sentinel has its own set of norms and the SGA universe has a whole different set with the various alien cultures in the Pegasus Galaxy. Another theme is the exploration of new powers. The Sentinel's powers in the context of SGA's advanced technology and alien threats can lead to some interesting storylines.
Maybe there's a situation where an alien artifact is found on Earth that has a connection to Atlantis. The NCIS team starts investigating it, not fully understanding what it is at first. Then the SGA team gets involved because they recognize the technology. They work together to keep the artifact safe from various threats, both Earth - based and alien.
One good piece of 'sga crossover fanfiction' is the one where SGA characters cross over with the Mass Effect universe. It's really interesting to see how the different species and technologies interact. Another is the crossover with Firefly. The cultural differences between the two universes make for a great story.
One idea could be to have a character from SG1 accidentally end up in the SGA universe and have to adapt to the new technology and threats there. For example, Jack O'Neill could find himself on Atlantis and his military tactics and dry humor would create interesting interactions with the Atlantis team.
Another way is to join fanfiction communities or forums dedicated to either SGA or NCIS. Ask the members if they know of any good SGA NCIS crossover stories. They might be able to recommend some hidden gems that you wouldn't find through a simple search. Sometimes these communities also have their own collections or libraries of recommended fanfics.
Well, I'm not an expert on every single 'The Sentinel Crossover SGA' fanfiction out there. However, you can start by looking at the reviews and ratings of the stories. High - rated ones usually have engaging plots. For example, some might focus on how the characters from both universes interact in a new and exciting situation, like a joint mission to save a planet that's on the verge of destruction. This can make for a really thrilling read.
Combine the best traits of characters from both. For example, take Sheppard's leadership and piloting skills from SGA and mix them with Daniel Jackson's knowledge and curiosity from SG1. This creates a new and interesting character dynamic.
One interesting story could be 'The Lost Magic in Hogwarts and Atlantis'. It combines the magic of Harry Potter's world with the mystery of the Atlantis from SGA. Another might be 'Harry Potter's Adventure in the Pegasus Galaxy' where Harry somehow ends up in the Stargate Atlantis universe and has to use his magic skills to survive and help the Atlantis team.
Harry Potter himself is often very popular. He brings his magical skills and heroic nature into the crossovers. Another popular character is Hermione Granger. Her intelligence and knowledge of magic can be really interesting when combined with the SGA elements. Ron Weasley also shows up a lot, with his loyalty and sometimes comical nature.
