Another great fanfic is 'In the Shadows with Harry and Rodolphus'. In this story, they are both on a secret mission in the wizarding underworld. The author does a wonderful job of building tension and exploring their characters as they face various challenges together. It's a real page - turner with lots of plot twists.
One good one might be 'Rodolphus' Redemption' where Rodolphus starts to question his Death Eater ways after meeting Hermione. It shows a different side of him and how their interactions could lead to a change in the wizarding world's power dynamics.
Well, there's 'Rodolphus Lestrange: The Unseen Side'. This fanfic delves deep into his psyche, revealing aspects of his character that were not shown in the original books. It's really interesting to see how the author portrays his relationship with Bellatrix in a new light. Also, 'In the Shadow of Rodolphus' is a good read. It shows his life during the rise of Voldemort and his inner conflicts. Then there's 'Rodolphus' Reckoning' which focuses on his journey after Voldemort's fall.
There's also 'A Different Path'. This fanfiction takes a unique approach to the relationship. It shows how the two characters could have interacted in a more positive way than in the original books, with interesting plot twists and character developments. It's really a great read for those interested in this pairing.
I'm not sure if there is such a specific fanfiction. It's a rather unusual and dark concept considering Bellatrix's loyalty to Voldemort and her actions in the original story. Fanfiction can be very diverse, but this would likely be a very niche and perhaps controversial take on the Harry Potter universe.
One popular 'Rodolphus Lestrange x Harry Potter' fanfiction is 'The Unlikely Bond'. It explores a rather unique relationship between them where they are forced to work together in a situation against a common enemy. This fic delves deep into their characters, showing how they overcome their initial hatred and distrust.
One common theme is redemption. Many fanfictions explore whether Rodolphus can be redeemed for his actions as a Death Eater. Another theme is his relationship with Bellatrix. Writers often delve into the complex nature of their marriage. Also, his role in the wizarding war and how he might have influenced certain events is a common theme.
I'm not sure if there is such a specific fanfiction. Fanfiction can cover a vast range of wild and creative ideas, but this one seems rather unusual. It goes against the original lore in many ways. In the original 'Harry Potter' series, Harry is James and Lily's son, and Bellatrix is a Death Eater who has a completely different story arc.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfics from various fandoms, including Harry Potter, and you're likely to find some great Harry and Rodolphus ones there.
A possible plot could be that Rodolphus Lestrange, having some remorse after Voldemort's defeat, tries to make amends by approaching Harry Potter. Harry is initially skeptical but then realizes that Rodolphus has some valuable knowledge about dark magic artifacts that could be a threat if they fall into the wrong hands. So they form an uneasy alliance. Also, there could be a plot where a spell gone wrong during a fight between Harry and Rodolphus causes them to swap minds for a short time, leading to humorous and also tense situations as they have to navigate each other's lives.
It would be extremely strange. Harry is known for his connection to the light side, while Bellatrix is one of the darkest characters. If he were their son, perhaps he would struggle with his own identity. He might have been raised in a very different environment, surrounded by Death Eaters, but still have some innate goodness in him that would cause internal conflict.
