One idea could be exploring the backstories of minor characters in more depth. For example, the lives of the pilots who don't get as much screen time. Another could be a what - if scenario where a different character discovers the Cylons' plan earlier. And a third could be a story about a new colony that is formed during the journey through space.
There are many possibilities. For instance, a fanfiction that focuses on the cultural exchange between different human colonies within the fleet. How they adapt to each other's traditions and beliefs. Or you could write a time - travel story where a character goes back in time to try and prevent the Cylon attack. Another interesting plot could be a story centered around a character who has a special ability that no one else in the fleet has, and how that ability affects the overall situation.
One idea could be the Stargate teams finding a derelict Battlestar and trying to figure out its technology. They might encounter some of the Cylon technology which could pose a new threat or a source of new knowledge for them.
A possible fanfiction plot could involve a character from Battlestar Galactica having some latent magical ability. This person discovers the world of Harry Potter through a strange portal or something. They then have to learn how to use their magic while also trying to bring some of the magical solutions back to help their own people in the fight against the Cylons. And perhaps there could be a conflict between the magic - using wizards and the technology - reliant Galactica crew at first, but then they learn to work together.
They have some similarities and differences. The TV show might focus more on action and drama, while the comic could offer a different visual take and storylines.
One interesting storyline could be a self - insert character who has unique knowledge about the Cylons' weaknesses and uses it to help the Galactica crew. For example, they might know a way to disrupt the Cylons' communication network that was never discovered in the original series.
The secrets of the Battlestar Galactica shipyards in fanfiction can be quite diverse. It could be that the shipyards are actually a front for something else entirely. Maybe they are secretly researching ways to communicate with other civilizations that are not supposed to be known. There could also be a hidden level in the shipyards where captured enemy technology is being reverse - engineered. Also, there might be a select group of people who know about a special power source that is being harnessed in the shipyards, which could potentially change the balance of power in the Galactica world.
One great 'Battlestar Galactica Crossover Fanfiction' is the one that crosses it with 'Star Trek'. It imagines how the different technologies and cultures from both universes would interact. For example, the warp drive of 'Star Trek' and the FTL jumps of 'Battlestar Galactica' could lead to some really interesting scenarios in terms of space travel and exploration. The characters from both series also have different moral compasses, which makes for some great conflict and character development when they meet in this fan - made crossover universe.
There's this amazing 'Battlestar Galactica 2003 Crossover Fanfiction' that combines it with the world of 'Firefly'. The space cowboy aesthetic of 'Firefly' meshes well with the more militaristic feel of 'Battlestar Galactica'. The fanfic focuses on the crews of both shows coming together to face a common threat in space. It has some great character moments and the action scenes are really well - written.
Some interesting concepts would be related to the cultures. The Spartan culture in Halo with its focus on combat and loyalty could interact in an exciting way with the more democratic and diverse culture of the colonies in Battlestar Galactica. Then there's the idea of the Halo's Forerunners' technology falling into the hands of the characters in Battlestar Galactica. It could change the power dynamics completely. Also, the Cylons' ability to infiltrate and the Covenant's religious fanaticism could create some really complex and engaging storylines when combined.
One interesting crossover could be the use of Destiny's weaponry in the Battlestar Galactica universe. For example, Guardians from Destiny could bring their advanced energy guns to help the crew of the Galactica in their fight against the Cylons. This would change the power dynamics in the BSG battles.
One interesting concept is the idea of changing key events in the original Battlestar Galactica storyline. For example, a character might travel back in time to prevent a certain battle from happening, which could have huge ramifications for the future of the human race in that fictional universe. Another concept could be characters from different time periods within the Battlestar Galactica world interacting in unexpected ways. It could lead to new alliances or rivalries that were not part of the original narrative.
