Some of the best Smallville and Stargate SG1 crossovers involve character interactions. For instance, Lex Luthor could get involved with the NID from Stargate SG1. This could create a whole new dynamic of power - hungry characters vying for control over alien technology. It makes for a really exciting read as the two universes collide in unexpected ways.
Another way it blends them is through the use of technology and powers. The advanced tech of Stargate SG1, like the Stargate itself or the zat guns, can be contrasted with Clark's superpowers in Smallville. Maybe Clark has to deal with a situation where the Stargate technology is malfunctioning and his powers are the only way to save the day. It's this kind of mixing of elements that makes the crossover so interesting.
I like 'Buffy in the SGC'. In this fanfic, Buffy is somehow transported to the Stargate Command. The author does a good job of showing how Buffy's slayer skills are both useful and a bit out of place in the military - science - fiction setting of Stargate. There are some really cool fight scenes against Goa'uld with Buffy leading the charge.
One great 'Stargate Atlantis' and 'SG1' crossover fanfiction is 'The Lost City Reunion'. It brings together characters from both series in an exciting adventure. The story focuses on how the teams from SG1 and Atlantis collaborate to face a new and powerful enemy. It has great character interactions and stays true to the spirit of both shows.
I think 'Beyond the Gate' is a must - read. This story takes Jack and Sam on a mission that forces them to rely on each other more than ever. It not only shows their professional relationship but also how their personal feelings start to surface during difficult situations. The plot is engaging and the writing style is very immersive.
Well, in a Stargate SG1 and NCIS crossover fanfiction, there could be a situation where an alien artifact is found at a crime scene that NCIS is investigating. The SG1 team is then called in to figure out what it is. Daniel Jackson could start rambling about the historical and alien significance of the artifact, while Abby from NCIS is trying to analyze it from a forensic perspective. It would be a great mix of science - fiction and crime - solving elements.
Well, character consistency is key. The characters from SG1 should act like they do in the show. Also, a good crossover will blend the different universes or shows' lore smoothly. For example, if it's a crossover with Stargate Atlantis, how the technology and cultures interact is important.
The popularity of Stargate SG - 1 crossover fanfiction lies in the ability to combine different fictional universes. Fans love seeing their favorite SG - 1 characters in new and unexpected situations with characters from other shows.
Well, 'A Matter of Honor' is also a very good one. It expands on the relationships between the characters in the SG1 team. The story is full of action and also explores the moral and ethical dilemmas they face during their missions. It gives a more in - depth look at the personalities of Jack, Sam, Daniel and Teal'c. For example, it shows how they handle difficult decisions when dealing with different alien cultures and their own military protocols.
There are fanfictions where the advanced technology of Stargate is introduced into the Smallville universe. For instance, imagine the Langarans sharing their medical knowledge with the Smallville doctors. This could lead to some interesting character development as the Smallville characters have to adapt to new ways of thinking. Also, a crossover could explore how the alien races from Stargate would react to a being like Clark Kent with his superhuman abilities.
There is also 'Hidden Feelings'. This story is really good as it focuses on the emotional side of Sam and Jack. It shows how they struggle with their feelings in the midst of their military duties. The author does a wonderful job of portraying their internal conflicts and the slow build - up of their relationship.
