Another might be an OC who is from a different background than the main crew, like a civilian scientist who was accidentally brought along. Their different perspective could create a lot of interesting interactions and story developments as they struggle to adapt to life on the Destiny and contribute to the mission.
There are fanfictions that focus on character backstories. Say, a detailed account of Rush's life before the Stargate program. It might include his early academic achievements, his relationships, and what led him to be so obsessed with the Destiny mission. This kind of fanfiction can give a deeper understanding of the complex character that is Rush.
First, study the existing universe. Know the rules of Stargate technology, the different alien races, and how the Destiny operates. Then, give your OC a clear backstory. For example, if they're a military character, explain their training and past missions. If it's a civilian, what led them to be involved with the Stargate in the first place.
One good stargate oc fanfic could be those that focus on creating unique adventures for the original characters. For example, a story where an OC discovers a long - lost Goa'uld technology. Another might be about an OC's journey to become a part of the Stargate team and how they adapt to the challenges.
A possible storyline is that the Marvel OC is a scientist who has created a device that can nullify superpowers. The OC believes Wonder Woman's powers are too dangerous and decides to use the device on her. Wonder Woman, of course, sees this as a threat and fights back. During the battle, the OC discovers that Wonder Woman's powers are more than just physical strength and magic, but also her unwavering will. Or perhaps the OC is a magical being from Marvel who mistakes Wonder Woman for an enemy due to a misunderstanding. Their battle then becomes a journey of discovery as they learn about each other's true natures.
An interesting Steven Universe OC fanfic could focus on an OC who is a healer Gem. This OC could have the power to heal not only physical wounds but also emotional traumas. In the fanfic, they could travel around the universe, helping Gems and humans alike. They might face challenges like being drained of their energy when they heal too many at once, or they could encounter Gems who don't believe in their powers. Maybe they join Steven and the Crystal Gems on their adventures and use their healing skills to mend relationships within the group.
Another storyline could be an OC who is a park ranger with a mysterious past. This ranger discovers a hidden part of the island that has dinosaurs not previously known to the park. They then have to figure out how to keep this discovery safe from those who might want to exploit it for profit or use the dinosaurs for illegal activities. This could lead to a race against time to protect these new dinosaurs and their habitat.
There is a fanfic called 'Beyond the Stars of Destiny' which is really good. It takes the crew on an unexpected journey to a parallel universe where they find a different version of the Destiny. This fanfic is full of action and some really thought - provoking moments as the characters have to deal with their doppelgangers and new threats in this strange new world.
One idea could be to cross Stargate Universe with Stargate SG - 1. Maybe the Destiny crew discovers an ancient technology that was originally developed by the SG - 1 team on Earth. This could lead to a joint mission where both crews have to work together to unlock the secrets of the technology and use it to save both their ships and Earth from a new threat.
The Stargate was a classic science fiction novel. It described how humans would enter interstellar space through a huge stargate in the future to explore unknown planets and civilizations. The movie was full of imagination and technology. In the movie, humans crossed the universe and entered a brand new world by building a huge stargate. This new world had countless mysterious planets and unknown civilizations. Humans needed to constantly explore and take risks in order to survive. The scene design and special effects in the movie were very exquisite, making people feel as if they were there. In addition, the Stargate also discussed some important scientific and philosophical issues. For example, how could humans survive and develop in such a vast universe? How do time and space affect human life and actions? These questions were deeply explored and pondered in the novel, which benefited the audience a lot. All in all, Stargate was a sci-fi movie that was worth watching. It showed the infinite possibilities of science fiction movies and also triggered people's thinking and discussion about the universe and life.
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.
