A great concept for a sentinel stargate crossover fanfiction could be that a Sentinel is recruited into the Stargate program because of their unique abilities. Their ability to 'see' things on a different level could help in deciphering the complex symbols and technology related to the Stargate. For instance, they might be able to sense the correct dialing sequence for a previously unvisited planet just by being near the DHD. Their enhanced physical abilities would also come in handy during off - world missions, like being able to fight off alien creatures more effectively than the regular team members.
One idea could be that a Sentinel's enhanced senses are used to detect a hidden Goa'uld base that the Stargate team has been searching for. The Sentinel could sense the unique energy signatures or the presence of the symbiotes in a way the normal technology couldn't. Another idea is to have a Sentinel character be accidentally transported through the Stargate to a different planet. There, they have to use their Sentinel abilities to survive and team up with the Stargate team members who are also on a mission there.
One idea could be that the Stargate team discovers a world where the Sentinel abilities are a natural part of the population. The Sentinels' powers could be used to help the Stargate team in their exploration and battles against alien threats. For example, their enhanced senses could detect hidden Goa'uld symbiotes or hidden traps in ancient ruins.
The main characters are likely to be a mix of the well - known figures from both the Sentinel and Stargate franchises. In the Sentinel side, Blair Sandburg might be there, given his importance in that universe. From Stargate, Teal'c could be one of the main characters. The fanfiction might also focus on some secondary characters from both universes and give them more prominence as they navigate the challenges of this crossover, like how they deal with the differences in technology and power systems.
One interesting concept could be the combination of the Sentinel's unique abilities with the technology and settings of Stargate. For example, how the Sentinel's heightened senses might interact with the alien technologies in the Stargate universe. Another could be the character crossovers, like how the Sentinel characters might fit into the existing Stargate teams and their dynamics.
A Sentinel and Daniel Jackson could have some interesting interactions. The Sentinel's intuitive understanding could complement Daniel's academic knowledge. For example, when exploring an ancient ruin, the Sentinel might sense a hidden danger that Daniel's research misses. Another good interaction could be between a Sentinel and Teal'c. Teal'c's warrior skills and the Sentinel's enhanced combat abilities could lead to some intense training or fight scenes together.
A possible fanfiction could revolve around a joint mission. The races from Babylon 5 and the teams in the Stargate universe come together to face a common threat. Maybe an ancient evil that has the power to destroy both their worlds. They would have to combine their knowledge and resources, like the Psi Corps abilities from Babylon 5 and the Ancient technology in Stargate.
For starters, you can focus on their skills. For instance, the Stargate characters' knowledge of different cultures and advanced technology can be paired with the Sentinels' unique abilities like their enhanced senses. Daniel Jackson from Stargate could study Sentinel culture, while a Sentinel could use their senses to help Jack O'Neill in combat situations.
One idea could be a crossover with a superhero universe. The Sentinel could team up with well - known superheroes to fight a common enemy. For example, joining forces with Superman to stop an alien invasion that threatens both their worlds.
Well, in Roswell Stargate crossover fanfiction, there might be a plot where the characters from Roswell get involved in Stargate missions. Imagine the Roswell gang having to deal with the Goa'uld or the Replicators. It could also be about how the technology from Stargate affects the lives of the Roswell aliens. For instance, the Stargate could be a way for them to find a cure for their alien - related problems or a means to enhance their powers.
One idea could be that the Spartans from Halo are sent through a Stargate to an unknown planet in the Stargate universe. They have to team up with the SG teams to fight off a common enemy like the Flood that has somehow spread to that planet. Another could be a scenario where the technology from both universes is combined. For example, the Covenant's energy shields are integrated with the Stargate's shield technology.
In a Stargate Babylon 5 crossover fanfiction, a possible plot could revolve around a mysterious energy source. This energy source could be something that is of great interest to both universes. Scientists from Stargate and Babylon 5 could team up to study it. However, different factions within each universe may have different ideas about how to use this energy. This could lead to internal conflicts as well as conflicts between the two universes. It would be a story full of political intrigue, scientific discovery, and adventure.
