The idea of growth and development is very common. Terry starts as a bit of an outsider but grows into a full - fledged member of the Bat family. Loyalty is another theme. He has to prove his loyalty to the family and they have to show their loyalty to him. And of course, the theme of justice, as they all fight crime together in the Gotham city setting.
A prevalent theme is the struggle between Terry's normal life and his life as part of the Bat family. It's about how he balances school, friends, and being a hero. Also, the theme of legacy comes up a lot. He has to deal with the huge legacy of Batman and the Bat family. There are also fanfics that explore his relationships with other young heroes in the Bat family, which is also a recurring theme.
Identity is a big theme. Nightwing has his own identity separate from being Robin or part of the Bat family, and fanfics often explore how he balances that. Also, redemption can be a theme in some cases, especially when dealing with his past mistakes or the mistakes of the Bat family as a whole. It's about making things right and growing as a character.
Growth and development. School is a place for learning and growing. In these fanfics, the Bat family members might learn new skills, not just academic ones but also social and emotional skills. For example, Tim Drake might learn how to make more friends at school, which in turn helps him in his crime - fighting as he can gather more information from different sources.
Well, I know a fanfic where Terry gets involved in a mystery-solving adventure with the Bat family. It shows his growth and how he fits into the family's world of vigilante justice. Another one might be about Terry training with different members of the Bat family and the challenges he faces during that process.
One common theme is friendship. Many fanfics explore how Candy and Terry support and care for each other as friends.
Love or romance is also likely to be a common theme. The relationship between Candy and Terry, whether it's a budding romance or a long - standing love, might be central to many fanfics. Another possible theme could be growth. They could be growing as individuals while being in each other's lives, learning from their experiences together.
One common theme is empowerment. Since Terry is a girl in these fanfics, she often has to overcome gender - based obstacles. Another theme could be friendship, especially with other characters who support her in her heroics. For example, her relationship with her sidekick or mentor.
One common theme is romance. It could be a love story between Terry and another female character, exploring their relationship and the emotions involved.
One common theme is moral ambiguity. Since it's about a 'criminal' bat clan, the line between right and wrong for the characters becomes blurred. Another theme is power struggles. Within the clan, different members may vie for power using criminal means. And secrecy is also a big theme, as they often have to keep their criminal activities hidden.
Another theme is discovery. Bat ponies may discover new powers or parts of the Equestrian world. In some fanfics, they might find hidden caves or ancient magic that only they can access because of their unique nature as bat ponies. This makes for exciting adventures.
One common theme is the clash of different power sets. Danny has his ghost powers while the Bat Family has their own set of skills and gadgets.
