The security officers on the Enterprise during the events of The Alternative Factor are often overlooked. In fan fiction, you could give them more backstory and more significant roles. Maybe one of them has a personal vendetta against the alien entity because it reminds him of a threat from his past. Another could be a science officer who was overshadowed by the main characters in the original but has some unique insights about the alternative factor.
There's that one engineer who only had a couple of lines in The Alternative Factor. In fan fiction, this character could be given a major role. He could be the one who comes up with a creative solution to the power drain that the Enterprise is experiencing due to the alternative factor. Maybe he has a personal struggle as well, like trying to prove himself to his superiors after a previous mistake, and this situation gives him the chance to shine.
A great plot for a fanfic could be what if the main character from The Alternative Factor had a different motivation. Instead of the somewhat ambiguous reasons in the original, he could be trying to save his home planet which is being affected by the space - time rift. This would add a new layer of depth and emotional connection to the story. Also, we could see how the Federation reacts differently to this new information.
Molly is often overlooked but has great potential. In fanfiction, we could explore more of her relationship with her father and how that affects her role as a Starcatcher. We could also see her develop her own unique magical abilities beyond what's shown in the original story.
Donkey's dragon girlfriend could be more prominent. In fan fiction, she could have her own set of challenges that Shrek and Fiona help her with. For example, she might be having trouble fitting into the ogre - friendly world, and Shrek and Fiona could offer their support and advice.
Commander Bly. He doesn't get as much spotlight as some other clone commanders, but he has a lot of potential. His relationship with Aayla Secura could be explored more in fan fiction. Another is Barriss Offee. Before her fall, she had a lot of untapped storylines. And then there's Tiplee. She was a strong female clone commander who could be the center of some great fan - made stories.
I think Wylie could be one. He has so much potential but often gets overshadowed by the main characters. In fan fiction, his relationship with other characters, like his family ties, could be explored more, and he could be given his own adventures that showcase his unique skills and personality.
Well, the traveller is likely to be one of the main characters. They would be the central figure around which the story revolves.
Data is also a favorite. His quest to understand humanity and his unique abilities provide rich material for fan stories. Writers might explore his experiences in new and different ways, like his reactions to unusual situations that don't occur in the main series.
Lady Laena Velaryon is another one. A fan fiction could explore her life more in - depth. Her relationship with her dragon, Vhagar, could be a central point. Also, her marriage to Daemon Targaryen and how she really felt about it. Maybe she had her own ambitions that were overshadowed by the events around her.
Captain Kirk is often popular. His leadership skills and charisma can be a great asset in the chaos of WW3 scenarios in fan fictions.
Luna Lovegood is a great choice. She has such a unique personality and view of the wizarding world. There's so much more that could be explored about her family, her beliefs, and her adventures outside of what we saw in the books. Another is Kreacher. His loyalty to the Black family and his complex relationship with Sirius could be delved into deeper.
