A time travel fanfiction could also focus on a member of SG1 getting stuck in the past. For example, Daniel Jackson could be trapped in ancient Egypt. He would have to use his knowledge of the Goa'uld and the Stargate to try and find a way back while also influencing the course of history in small ways, like helping the locals resist Goa'uld oppression without changing history too much.
Another great plot could be time travel that accidentally creates an alternate timeline. The SG1 team then has to find a way to fix it. They might face different versions of themselves or find that their relationships with allies and enemies have changed drastically, which would make for a really exciting story.
There's also 'A Time - Twisted Journey'. This fanfic focuses on an OC who travels through time to prevent a major disaster in the Stargate SG1 timeline. It's full of action and mystery, with the OC having to team up with the regular SG1 characters in unexpected ways. The author does a great job of keeping the tension high throughout the story.
One interesting story could be about a new alien race that the SG1 team discovers. This race has a unique culture and technology that challenges the team's understanding. For example, they might have a way of traveling through time, which leads to all sorts of adventures as SG1 tries to figure out how it works and how it could be used or stopped if it's dangerous.
There are fanfictions that deal with time - travel in the Stargate SG - 1 universe. The team might go back in time to prevent a major disaster from happening, like stopping the Goa'uld from ever rising to power. Some fanfictions also focus on the Asgard, exploring their culture and technology more deeply. And then there are those that introduce new alien races that the team has to interact with, which can lead to all sorts of interesting plot twists.
Well, for one thing, it gives fans a chance to be creative. They can create an OC with unique abilities or a special backstory. And when you combine that with time travel, you can have the OC interact with different versions of the Stargate SG1 characters. For example, they could meet a younger or older version of Jack O'Neill. It's like opening a whole new set of doors in the Stargate world.
One of the most interesting storylines could be a situation where the technology from Stargate SG1 somehow finds its way into the NCIS world. For example, a Goa'uld symbiote might be discovered during an NCIS investigation on a military base. The NCIS agents, being used to normal criminal investigations, would be completely out of their depth dealing with alien technology and the threat of a parasitic alien life form. This would force them to team up with the Stargate SG1 team who have the expertise in dealing with such threats.
One interesting Stargate SG1 fanfic could be a story that focuses on an alternate timeline where the Goa'uld manage to take over Earth. It could explore how the remaining humans fight back underground. Another might be a fanfic that delves into the backstories of minor characters, like the technicians at the SGC. There are also fanfics that involve crossovers, for example, with other sci - fi universes.
Daniel Jackson, on the other hand, would be fascinated. His love for history and knowledge would make him eager to explore different time periods. However, he would also be very aware of the potential consequences of changing history and would struggle between his curiosity and his sense of responsibility. Time travel could also bring out a more protective side in him as he tries to preserve the past as it should be. Sam Carter might see time travel as a scientific challenge. She would be eager to understand the mechanics behind it, like how the Stargate manages to open a wormhole not just in space but also in time. This could lead her to some dangerous experiments as she tries to figure it all out, and she might also use her knowledge of future technology to try and improve the past, especially when it comes to fighting the Goa'uld.
One interesting concept is alternative timelines. Fan fiction often explores what would happen if certain events in the Stargate SG1 series occurred differently. For example, if Daniel Jackson hadn't ascended the first time. Another concept is character crossovers, like bringing in characters from other science - fiction universes and seeing how they interact with the Stargate SG1 crew. Also, there are fictions that focus on the backstories of minor characters, giving them more depth and development.
A possible plot could involve an immortal villain from the Highlander world using the Stargate network to spread chaos across different planets. The SG1 team, with the help of some friendly Highlander characters, has to track him down and stop him before he causes too much destruction.
There are some fanfictions where a character in Stargate SG1 has a baby unexpectedly. For example, a story might focus on how Sam Carter manages her duties as a scientist and a new mother, and how her team members support her. These types of stories often explore the more human side of the characters.
