Well, for Battlestar Galactica 2003 fanfic, Roslin is a great character to write about. She's the president and has to deal with political intrigue, as well as the survival of the human race. Her terminal illness also adds a layer of complexity to her character. Saul Tigh is also quite interesting. His loyalty, his drinking problem, and his relationship with his wife all provide rich material. And let's not forget about Boomer, the Cylon sleeper agent. The conflict within her, between her human side and her Cylon programming, is a goldmine for fanfic writers.
Definitely Kara 'Starbuck' Thrace. She's a complex character with a tough exterior but many internal struggles. Her skills as a pilot and her rebellious nature make her a great subject for fanfic. Another is Gaius Baltar. His moral ambiguity and his relationship with the Cylons offer a lot of material for writers to explore.
In my opinion, Admiral Adama is really interesting to write about in Battlestar Galactica 2003 fanfic. He has the weight of leadership on his shoulders, making tough decisions that can mean life or death for his people. Also, Six, the Cylon, is fascinating. Her different versions and her influence on Baltar and the overall story arc give a lot of scope for creative writing. And then there's Lee 'Apollo' Adama, with his own set of values and his relationship with his father and the rest of the crew, which can be explored in many ways in fanfic.
Admiral Adama is a very popular character to write about. His leadership and the tough decisions he has to make provide a lot of material. Starbuck is also popular. Her rebellious nature and piloting skills are great for creating exciting stories. And Baltar, with his complex relationship with the Cylons and his own moral ambiguity, is often a focus in fanfiction.
One of the most popular themes is survival. Given the constant threat from the Cylons, stories often revolve around how the characters find ways to survive in a hostile universe. Another is exploration, like exploring new planets and encountering new species. And of course, there's the theme of heroism, with characters like Apollo and Starbuck showing great courage in the face of danger.
Admiral Adama is often a popular character in these fanfictions. His leadership qualities and strategic mind make him a key figure in any time - travel related plot. He could be the one making decisions about how to use time travel to the advantage of the fleet.
The Cylon characters can be quite popular too. Fan fiction might delve into their inner workings and motives. For example, a story could be about a Cylon who begins to question its programming and tries to find a way to coexist with the humans, which is very different from their typical role in the original series.
Often, characters who are strong leaders or have special skills are popular self - inserts. For instance, a character with military leadership experience from another universe might be a popular choice. They can step in and offer different battle strategies to the Galactica's crew.
From Battlestar Galactica, Commander Adama is a likely candidate. His strong leadership and strategic mind could be very useful in the Destiny universe. He might be able to lead groups of Guardians in important battles or missions. Also, Starbuck's piloting skills could be transferred into Destiny's space battles, making her a fan - favorite in the crossover fanfiction.
Master Chief from Halo and Apollo from Battlestar Galactica could be an interesting pair. Master Chief is a super - soldier with incredible combat skills, and Apollo is a skilled pilot and military leader. Their different skillsets could lead to some great teamwork in a crossover story. Another possible pair could be Cortana and Starbuck. Cortana is an AI with vast knowledge, and Starbuck is a brash but talented pilot. They could have some really interesting exchanges, with Cortana providing strategic advice to Starbuck.
One interesting concept could be the different alien cultures and their hierarchies. For example, some fanfics might explore an alien species where females are the dominant gender in their society, which is a contrast to the human culture in Battlestar Galactica. Another concept could be the unique technologies of the aliens. Maybe they have a way of traveling through space that is far more advanced than the humans', like being able to open portals instead of using traditional FTL drives.
Some of the main characters are Admiral Adama and Captain Apollo.
First, know both universes well. For 'battlestar galactica', understand its characters like Adama and Starbuck, their relationships, and the overall plot of the show. If you're crossing it with, say, 'Mass Effect', study the races, cultures, and technology in 'Mass Effect'. Then, find a unique concept for the crossover. Maybe it's a shared threat that both universes have to face together. Keep the characters in - character and use their voices correctly. For example, if you have Commander Shepard from 'Mass Effect' interacting with Adama, they should each act as they do in their original stories while also reacting to the new situation.
