Another interesting fanfic could be about Voight forming an unexpected alliance with a character from another unit. They might start off on the wrong foot but gradually learn to respect and rely on each other, all while solving a complex case that spans across different departments.
A fanfic could focus on Voight's backstory. Maybe he has an old case that resurfaces, and he has to deal with the ghosts of his past while still leading his team. It could show his vulnerability and determination in the face of personal and professional difficulties.
There are quite a few fanfics out there. One good place to start looking is on fanfiction.net. You might find some stories that really explore the relationship between Voight and his daughter in unique ways, like dealing with the challenges of his job and how it affects their family dynamic.
He has a sense of justice that can be a bit unorthodox at times. In fanfic, this might lead to him bending the rules a little to get the bad guys. But he always has the greater good in mind. He also has a lot of emotional depth, which can be explored when he's dealing with personal losses or when his past traumas are brought to the surface.
It's interesting because it gives a different view of the Chicago PD world. We see the cases and the police work, but when you focus on Voight's daughter, you get to see how the events in the show impact a family member. It could be about her dealing with the secrecy of her father's job or the loyalty within the police force that her father is a part of. There are so many angles to explore.
One great 'chicago pd fanfic' is 'The Blue Line Bonds'. It delves deep into the relationships between the characters outside of their regular work scenarios. The character development is on point and it gives a fresh perspective on the show's dynamics.
A third fanfic to check out is 'Hailey's Hidden Past'. This one delves into her past experiences that made her who she is today. It reveals some secrets she has been keeping and how they start to surface during a particularly difficult case. It's a great read for those who want to understand her character more deeply.
One idea could be a joint emergency situation where a building fire is also a crime scene. Maybe the arsonist is still on the premises and the teams from both Chicago PD and Chicago Fire have to work together. The PD has to search for the suspect among the chaos and the firemen have to put out the fire while also trying not to destroy evidence.
One idea is that Lindsay gets hurt by a booby - trap. She's exploring a crime scene and accidentally triggers a hidden trap. It injures her leg badly. She then has to rely on her colleagues to carry on the investigation while she recovers. This could also lead to some interesting character development as she has to deal with being incapacitated for a while.
You can start by looking on fanfiction.net. It has a large collection of 'chicago pd fanfic' with different themes and writing styles.
Another idea is that Erin is hurt during a hostage situation. She might be trying to negotiate with the hostage - taker when things go wrong. The hostage - taker could attack her, leaving her with some serious wounds. Her colleagues would then have to take over the negotiation and also ensure Erin gets medical help as soon as possible.
One common theme is family. Since the OC is a sister, there's often a focus on family dynamics, like loyalty and protection. Another theme is fitting in. The sister OC has to find her place in the Chicago PD environment which can be tough.
