One interesting aspect could be seeing how Tom Riddle's character develops differently. Maybe he gains new knowledge from the books that alters his path towards becoming Voldemort. For example, if he reads about friendship and loyalty in the books, it might make him question his own dark tendencies.
He might become more empathetic. Fanfiction often shows different perspectives of characters, and this could make him see things from other's points of view, though it's a long shot considering his nature.
One great fanfiction could be 'A Different Path'. It explores what would happen if a female Harry Potter had a more complex relationship with Tom Riddle. In this story, the author delves deep into their interactions, with the female Harry being more empathetic yet still strong - willed. It changes the dynamic of their encounters compared to the original series.
Well, 'Bound by Fate: Tom and the OC' is a popular one. The OC in this story is a transfer student from a different wizarding school. When she arrives at Hogwarts, she immediately feels a strange connection to Tom. The story follows their journey as they come to terms with their soulmate bond. It has a lot of character development for both Tom and the OC, and the author's writing style is quite engaging.
The fanfiction likely deviates from the original in terms of character development. In the main story, Tom Riddle's path to becoming Voldemort is more about his own inherent darkness and experiences at Hogwarts. But in this fanfiction, the books he reads could potentially lead him down a different path. Maybe he becomes more empathetic if he reads certain books, which is completely different from his cold and power - hungry self in the original. It also might change the relationships he has with other characters as he has new ideas from the books.
You could also create a fanfiction where a new character, an orphan just like Tom, arrives at the orphanage. This new character could either be a positive influence on Tom, trying to show him kindness and friendship, or they could be in competition with him for the limited resources or attention in the orphanage. This would add a new dynamic to the story of Tom Riddle in the orphanage.
One great 'Akuma no Riddle Fanfiction' is 'The Unspoken Bond'. It delves deep into the complex relationships between the characters. The author does an amazing job of exploring the emotional depth that the original series only hinted at.
Maybe it's a group of future Ministry of Magic officials who have become corrupted by power. They view Tom Riddle as an anomaly from the past and fear that his knowledge of old magic could disrupt their control over the wizarding world, so they become the main antagonists in his journey.
Tom's character could become more vengeful. Meeting his father, who may have abandoned him, could make him more determined to prove his worth and power. He might see his father as a symbol of all those who have wronged him, and this could lead to a more rapid descent into darkness.
The 'lemon' in a Tom Riddle and Hermione fanfiction could be a metaphor for the unexpected. For instance, Hermione might find a lemon - like a magical object - that has some connection to Tom Riddle's past. This object could hold secrets that bring them closer in an unforeseen way. It could start as a simple mystery but turn into a more complex relationship as they explore the significance of this lemon - related item.
