Angelina Johnson is quite a popular choice. Since they already have a connection through Quidditch in the original series, it's easy to imagine their relationship developing into something more romantic in fanfiction. They understand each other's love for the sport and share a lot of common experiences within Hogwarts.
Luna Lovegood is another character that is sometimes paired with George. Their personalities are both quite unique. Luna's dreamy and eccentric nature could complement George's fun - loving and mischievous side. Maybe they meet at a magical creature - related event, and their shared love for the strange and wonderful in the wizarding world draws them together.
Some fanfictions also pair Luffy with Hancock. Given Hancock's infatuation with Luffy in the original series, it's not a stretch to develop a full - blown love story. Her powerful status as a pirate empress and Luffy's carefree nature can create an interesting dynamic, with Hancock trying to win Luffy's heart while he is mostly oblivious to her romantic intentions.
Albedo from Overlord and Sasuke Uchiha could also be a popular pairing. Albedo is a very loyal and somewhat possessive character, while Sasuke has his own complex motives and a dark side. Their relationship in fanfiction could explore themes of loyalty, power, and redemption. Albedo might be drawn to Sasuke's power and brooding nature, while Sasuke could be intrigued by Albedo's unwavering loyalty.
Naruto and Alex Mercer are often popularly paired. Naruto's positive attitude and strong will, combined with Mercer's raw power, make for an interesting dynamic. They can learn a lot from each other, like Naruto can teach Mercer about the importance of friendship, while Mercer can show Naruto some new ways to use power.
One popular character paired with Yami Yugi is Tea Gardner. In fanfiction, they often have a deep connection that goes beyond friendship. Their shared experiences in the world of Duel Monsters can form the basis of a romantic relationship.
One of the most popular themes is the idea of redemption for Draco. Many fanfictions explore how George could play a role in helping Draco move away from his family's dark and prejudiced views. Another theme is friendship against all odds. Given their different backgrounds and the animosity between Slytherin and Gryffindor in general, it's interesting to see how they could form a friendship. There's also the theme of rivalry turned partnership. They are both quite competitive in their own ways, and fanfictions often play with the idea of them competing at first and then realizing they are better off working together.
One popular theme is friendship. Many fanfictions explore how George and Harry's friendship develops over time, especially considering the age gap and their different personalities. It's interesting to see how they support each other through difficult times like the war against Voldemort.
One character that's frequently paired with Sebastian is Grell Sutcliff. Their interactions in the original work are complex, and in fanfiction, it can be turned into a love - hate relationship with a romantic undertone. Also, Mey - Rin is sometimes paired with Sebastian. Her clumsy yet endearing nature can make for an interesting dynamic in a love story where Sebastian might be both exasperated and charmed by her.
Definitely Tony Stark and Tyrion Lannister. They are both intelligent, witty, and a bit of an outcast in their own worlds. Fans love to imagine them coming together, sharing their knowledge and maybe even coming up with some grand plans to either take over Westeros or save the world from some new threat.
Vanya from The Umbrella Academy and Simon from Misfits are also popularly paired. Vanya's quiet and often overlooked nature in her own show, and Simon's somewhat awkward but kind - hearted character in Misfits can create a really sweet and emotional relationship in fan - created stories. The contrast between Vanya's powerful but suppressed abilities and Simon's more normal, relatable self can be a great source of story development.
Obviously, Ladybug and Chat Noir are the most popular pairing. Their dynamic in the show, with Chat Noir's flirty nature and Ladybug's more reserved attitude, makes for a great basis for a romantic relationship in fanfiction. However, some fanfictions also pair Marinette with other characters like Luka. Their relationship in the show was quite sweet, and in fanfiction, it can be explored further in a dating context. There are also fanfictions that pair Adrien with other characters aside from Ladybug, although this is less common.
