Hermione Granger is often a popular character. She can use her intelligence to figure out the implications of time travel and help Harry or deal with Tom Riddle in some way. For instance, she might research spells to counteract any dark magic that Riddle tries to use during their time - traveling encounters.
One character that would be great to pair with Harry and Tom is Remus Lupin. His kindness and understanding, as well as his own struggle with his werewolf side, could provide a different angle on dealing with Tom's darkness and Harry's heroism. Another good character is Bellatrix Lestrange. Although she was on Voldemort's side, her fanatical loyalty and powerful magic could make for an interesting dynamic in a fanfic where she might have to interact with Harry and a redeemed or different Tom. And of course, Ron Weasley. His friendship with Harry is well - known, and his reactions to Tom Riddle and the situations involving him could add humor and a down - to - earth element to the fanfiction.
In addition to them, there could be other characters from the original 'Harry Potter' series who play important roles. For instance, Dumbledore might still be a guiding figure in Harry's life. He could be suspicious of this new friendship between Harry and Tom and try to keep an eye on them. Hermione and Ron could also be part of the story, either supporting or being skeptical of Harry's new friendship with Tom.
One great 'Harry Potter Tom Riddle Fanfiction' is 'The Heir of Slytherin's Redemption'. It shows a different side of Tom Riddle, exploring what could have happened if he had been given a chance at a different path. It has a really interesting plot that keeps you hooked from start to finish.
A fanfic might explore how Harry Potter and Tom Riddle discover they are soulmates. It could start with strange dreams or premonitions that Harry has about Tom. As they get closer, they realize that their destinies are intertwined. This could lead to a conflict within the wizarding world as many would be against their union, seeing Tom as the future Voldemort, but Harry believes in the power of their soulmate bond to change Tom for the better.
One popular idea in such fanfiction could be that Harry, through some magical time - turning or alternate reality scenario, discovers Tom Riddle before he fully becomes Voldemort. Harry might see the good in Tom that was lost over time and tries to prevent his fall to the dark side. Their soulmate connection could be a powerful force that draws them together, even as their destinies seem so opposed.
One great 'Harry Potter' Tom Riddle slash fanfiction is 'The Heir of Slytherin's Heart'. It delves deep into the complex relationship between Harry and Tom Riddle. The author does an amazing job of exploring their characters in a new light, with a plot that keeps you on the edge of your seat.
I'm not sure if it's popular. It's a rather niche and unusual concept, so it might not have a wide following. But in the world of fanfiction, there are always small groups of people interested in unique and out - of - the - ordinary ideas.
One popular type of fanfiction in this vein could be about Tom Riddle's interaction with magical creatures during his time at Hogwarts. Maybe he discovers a creature that has some connection to the dark arts and tries to use it for his own gain. For example, he might come across a basilisk in the Chamber of Secrets earlier than in the original story and attempt to control it to intimidate other students.
No, it's not common. Tom Riddle is a very complex and dark character. His main focus in the original story is on power, domination, and his own dark magic. Fanfiction is usually a creation of fans for fun and exploration, and it's hard to imagine the cold - hearted Tom Riddle having an affinity for it. However, in some very creative fanfictions, this could be a really different and thought - provoking take.
