There are. A lot of fanfiction writers like to play with the idea of family bonds in the wizarding world. In the case of Harry and Tom as brothers, it can create a whole new set of stories. For example, how would Dumbledore react to this new relationship? And how would it affect the prophecy? These are the kinds of things that make these fanfictions so fascinating.
Well, a big theme is the power struggle. Harry is seen as the 'good' and Tom as the 'evil', but being brothers adds a new dimension. Also, the theme of identity. How does being brothers change who they are? It's complex and often explored in these fanfictions. They also might explore the theme of how their upbringing could have been different if they knew they were brothers from the start.
One common theme is the struggle between good and evil. Since Tom Riddle becomes Voldemort, his brother is often portrayed as having a battle within himself about whether to follow Tom into darkness or oppose him. For example, in many fics, the brother might initially be tempted by Tom's power but then realizes the true nature of his actions.
A lesser - known but really good one is 'The Riddle Brothers' Bond'. It focuses on the relationship between Tom and his brother. The author creates a complex dynamic where they both influence each other in unexpected ways, with some really cool plot twists along the way.
Sure. There are fanfics that play with this idea. They often create an alternate universe where their brotherhood changes the whole Hogwarts story. For instance, Tom might not become as evil as in the original story because of Harry's influence, or they could team up against other dark forces in the wizarding world.
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.
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.
