One common theme is redemption. Many fan fictions explore Desiree's journey towards redeeming herself for past actions. Another theme is self - discovery. Since her character has room for growth, writers often focus on her finding out more about herself.

One popular Smallville Desiree fan fiction could be those that explore her backstory in more detail. Maybe it delves into her life before coming to Smallville and how she got her powers if she has any.
One great Smallville Desiree Atkins fan fiction is 'Desiree's New Beginnings'. It explores her character in a new light, showing her growth and development outside of the main show plot. Another is 'Desiree and the Mysterious Force' which delves into her encounter with a strange force in Smallville.
One popular theme is the exploration of Clark Kent's early days in Smallville. Writers often delve into his relationship with his parents, like how they guided him in hiding his powers. Another theme is Clark's friendships, especially his complex relationship with Lex Luthor, which can be portrayed in different ways in fan fiction, such as emphasizing their early camaraderie or the slow build - up of their rivalry. Also, the development of Clark's powers and how he copes with them in a small - town setting is a common theme.
One interesting plotline could be the development of relationships among the characters in the harem. For example, how they handle jealousy and competition. Another might be the introduction of a new character into the harem and how it shakes up the existing dynamics.
In some fan fictions, a plot twist could be that Clark is captured by what he believes is a human organization, but it's actually a front for an alien invasion force that plans to use him as a key to open a portal to Krypton. Another twist could be that the capture is a ruse by the Green Arrow to teach Clark a lesson about being overconfident. And there could be a story where Clark is captured, and during his captivity, he discovers that his captors are actually his future descendants trying to prevent a catastrophic event in the past.
I'm not sure if there is such specific fan fiction available. Fan fiction can cover a wide range of themes and relationships, but this particular one might be quite rare or not in line with the general tone of the 'Smallville' series. It also might not be something that is widely promoted due to its rather inappropriate nature.
Clark Kent is obviously one of the most interesting. He has so many layers to his character, from the shy farm boy to the emerging superhero. His internal struggles with his powers and his moral compass make for great writing. Lex Luthor is another. His complex personality, with his intelligence and his slow descent into darkness, gives a lot of room for creative interpretations in fan fiction.
Clark Kent is often included as he is the central character in Smallville. His superpowers and kind heart make him a popular choice for the harem concept. Lois Lane might also be there as she has a strong connection with Clark.
