A common theme is mentorship. Often, the OC will be someone Giles takes under his wing, teaching them about the world of magic and mystery. For example, in many stories, Giles helps the OC understand their new - found powers.
One popular Giles OC fanfiction is 'Giles and the New Recruit'. It's a great story that shows an interesting relationship between Giles and a new original character. The OC is well - developed and the plot is engaging.
The exploration of their different cultural backgrounds is also a theme. Giles is from England with a very different upbringing compared to Buffy's American experience. Fanfictions might delve into how these differences play out in their relationship, whether it causes misunderstandings or brings them closer together. There are also fics that look at how they might interact in a more modern - day setting outside of the supernatural world, just as two people with a complex history trying to navigate normal life.
Well, his past often comes up as a theme. His time in England, his training, and his early experiences in the world of the supernatural. His loneliness is also a theme sometimes. Despite being part of a group, he can often feel alone in his knowledge and responsibilities. And his struggle with power, both the power he has and the power he has to keep in check, is a common theme in Rupert Giles fanfiction.
One popular Giles fanfiction might be those that explore his early days as a Watcher. For example, stories could focus on his training and the relationships he formed with his mentors during that time.
One common theme is the mentor - mentee relationship. Giles is Buffy's watcher, so a lot of fics explore how he guides her in her slayer duties. Another theme is the idea of family. Since Buffy doesn't have a typical father figure, Giles often fills that role in fanfiction. Also, the theme of sacrifice is there. They both are willing to sacrifice for each other and the greater good, and this is often explored in different ways in the fanfiction.
Well, I really liked 'Giles: The Early Years'. It gives a great backstory to Giles, showing how he got involved with the Council and his first encounters with the supernatural. 'A Day in the Life of Giles' is a charming short fanfic that just follows Giles through an ordinary day in Sunnydale, but with his unique perspective as a Watcher. There's also 'Giles and the Ancient Artifact' which has an exciting plot involving Giles and a mysterious magical item.
It's popular because it offers a different take on the relationship between Buffy and Giles. Their relationship has always been complex and adding a baby into the mix makes it even more so. It gives fans a chance to explore new dynamics and emotions.
One great Buffy Giles fanfiction is 'The Watcher's Daughter'. It explores a different dynamic between them, where Giles has a long - lost daughter who gets involved in the Buffy - verse. Another one could be 'Giles' Redemption', which delves into Giles' past mistakes and how he and Buffy deal with the consequences together. There's also 'Buffy and Giles: The Unspoken Bond' that focuses on the unspoken feelings and deep connection between the two characters.
