Their different skills. Tim is very good at detective work and Barbara is a tech - genius. In fanfiction, this allows for a lot of interesting plotlines where they combine their abilities to solve problems.
One great fanfiction could be 'Tim and Barbara's Team - up'. It shows their unique dynamic as they solve a mystery in Gotham together. Their skills complement each other well in this story.
A more comical fanfiction could be set in a world where all the characters from Naruto and DC are in a high school together. Naruto has a huge crush on Barbara Gordon, and he tries all sorts of wacky ways to get her attention, much to the amusement and annoyance of their classmates.
The story where she teams up with other female heroes is also a great Barbara Gordon story. It showcases her ability to work in a team, her leadership skills, and how she can contribute to a group effort. It's inspiring to see her interact with other powerful female characters and make a difference in the DC Universe.
One possible plot twist could be that their secret identities are at risk of being exposed right before the wedding. Maybe a villain discovers their relationship and plans to use it against them, causing chaos and forcing them to make difficult decisions between their love and protecting their loved ones and the city.
One possible scenario could be that in this fanfiction, they meet in a unique situation. Maybe they are both working on a case together in a world where the different superhero universes collide. Their relationship gradually develops, and the pregnancy adds an extra layer of complexity and emotional depth to their story.
I really like the fanfiction 'Male Babs in the Batcave'. It delves into how a male Barbara Gordon would interact with the other members of the Bat - family. It's full of interesting dialogues and a fresh take on the character's relationships within the Gotham universe.
One great 'Batman Barbara Gordon Fanfiction' is 'Oracle Rising'. It really delves into Barbara's transformation into Oracle. It shows her strength and intelligence in a way that's both engaging and true to her character.
One more theme is the exploration of her dual identity. As Barbara Gordon, she is a librarian or a normal citizen, but as Batgirl/Oracle, she is a crime - fighter. Fanfictions play with this duality, showing how she balances her two lives. Sometimes she has to keep secrets from her friends and family, and this creates interesting plot twists and character dynamics.
