Naruto and Sasuke are the most common pair, no doubt. Their story arc in the official Naruto plot has so many layers that can be re - imagined in a slash relationship. But we also see pairings like Gaara and Naruto in some naruto slash fanfiction. Gaara's initially dark nature and Naruto's ability to reach out to him can be an interesting basis for a relationship in these stories.
Harry Potter and Sirius Black are also paired quite often. Sirius was a very important figure in Harry's life. In slash fanfiction, with Harry being dark and powerful, their relationship can take on a different meaning. Sirius's wild and rebellious nature can be paired well with Harry's new - found power and darker side, creating a relationship that is full of passion and a sense of freedom.
Cory Matthews is one of the most commonly written characters. Since he's the central character in 'boy meets world', he naturally becomes a focal point in fanfiction. Shawn Hunter is also very popular. His complex backstory and his relationship with Cory make him an interesting character to write about. Topanga Lawrence is another one. Her strong personality and her relationship with Cory provide a lot of material for fanfiction writers.
One of the most commonly paired characters with Romeo is Natsu. Natsu is a very popular character in Fairy Tail, and some fanfiction writers like to explore a yaoi relationship between him and Romeo. Their different personalities, with Natsu being more hot - headed and Romeo being a bit more level - headed at times, can create an interesting dynamic.
Definitely Asta. His underdog story and his never - give - up attitude make him a favorite for many readers to be paired with. Then there's Yami. His rough - around - the - edges personality can lead to some exciting and sometimes comical interactions with the reader. And Fuegoleon is also paired quite often.

Sasuke is very commonly paired with 'Naruto as a girl' in fanfiction. Their relationship has a lot of potential for romantic development when Naruto is a girl. There's the whole dynamic of their rivalry and the underlying feelings that could be explored in a different way. Another common pairing is with Kakashi. Kakashi could be a mentor figure but also potentially have a different kind of relationship with a female Naruto, perhaps more protective or having a special bond.
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.
