There are some great Torchwood fanfictions out there with this unique concept. One place to start looking could be Archive of Our Own (AO3). It has a large collection of Torchwood fanfics, and you can search specifically for ones where Ianto is pregnant. You might find some that explore the emotional and physical aspects of his situation in really interesting ways.
Relationships are also a big theme. As I mentioned before, how his relationship with Jack changes is often explored. But also, his relationships with the other Torchwood members. They might be supportive, or there could be some jealousy or confusion among them. And of course, there's the theme of the pregnancy itself - the physical and emotional changes he goes through, like morning sickness, mood swings, and the anticipation of becoming a parent.
Definitely Jack Harkness. Given their close relationship in Torchwood, Jack would be one of the first to notice any changes in Ianto if he becomes a Time Lord. Gwen would also be involved. She might be suspicious at first or might be the one Ianto confides in. And of course, the other Torchwood members like Owen and Tosh would interact with him. Owen might be a bit jealous or intrigued by Ianto's new powers, while Tosh could be more understanding and help Ianto figure out how to use his Time Lord abilities.
Another popular one is 'Slow Decay'. It explores the darker side of Torchwood and the moral dilemmas the team often faces. The complex characters and the engaging storyline make it a favorite among many Torchwood fans.
One characteristic is the exploration of their complex relationship. They often have a deep, unspoken bond that fanfiction writers like to expand on. Another is the use of the unique setting from their original story. Writers will incorporate the sci - fi elements and the team dynamics into the fanfiction. Also, the emotional depth is a big part. There's usually a lot of angst, love, and loyalty portrayed in these fanfictions.
One of the top Torchwood novels is 'Long Time Dead'. It provides an interesting exploration of the afterlife in the context of the Torchwood world. The story is engaging and keeps you on the edge of your seat as the team tries to figure out what's really going on. Also, 'Risk Assessment' is a great novel. It shows the team in a different light, facing a threat that challenges them both personally and as a group.
There are quite a few interesting fanfictions on this topic. One popular one explores how Gwen's pregnancy affects her role within Torchwood. It delves into the challenges she faces, both physically and emotionally, while still trying to keep up with the alien - related tasks at Torchwood. Another fanfic takes a more light - hearted approach, focusing on the comical side of her pregnancy, like her cravings for alien - inspired foods that the team tries to find for her.
Character relationships are a key element. Ianto's interactions with the Companions, whether it's friendship, loyalty, or love, drive the story. For example, in many fanfics, his unwavering loyalty to a particular Companion is a central theme.
A common theme is his upbringing. It could be about his family values, how he was taught certain things as a child. Another theme might be his first adventures or experiences that set the stage for his future. For example, his first encounter with something mysterious in his hometown as a child.
