One great Lupin and Tonks fanfiction is 'The Lupin - Tonks Story' on FanFiction.net. It really delves into their relationship, from their initial meetings to the deeper emotional bonds. The writer captures Tonks' free - spirited nature and Lupin's more reserved personality very well, making their interactions seem natural.
Well, first of all, they have very distinct personalities. Tonks is this fun - loving, shape - shifting witch, and Lupin is the more brooding, intelligent wizard. Their contrast makes for an interesting dynamic. Also, their relationship in the canon is somewhat underdeveloped, so fanfiction writers get to fill in the gaps. They can explore how Tonks first fell in love with Lupin, how Lupin overcame his self - doubt to be with her, and all the little moments in between that we didn't get to see in the books. It's like they are a blank canvas waiting to be painted by creative minds.
FanFiction.net also has a lot of Lupin and Tonks fanfiction. Just use the search bar and type in their names. You might find some hidden gems there. Some authors are really dedicated to exploring their relationship in unique ways on this platform.
In many lupin tonks fanfictions, the theme of sacrifice is present. Lupin may sacrifice his own happiness for Tonks' safety or vice versa. Another common theme is the idea of redemption. Lupin, with his werewolf nature which is often seen as a 'flaw', finds redemption through Tonks' love. Also, the theme of friendship within their relationship is important. Their friends play a role in either supporting or challenging their relationship, which is often explored in these fanfictions.
One possible scenario in this fanfiction could be that Teddy shows some unique magical abilities that remind Remus and Tonks of their own magical heritages. Maybe Teddy can transform in a way that combines both werewolf and metamorphmagus traits, which would be a really interesting plot point. It could also explore how Remus and Tonks, who had such a tragic end in the original story, get to experience some happy moments with their son Teddy through the magic of fanfiction.
One possible reason could be his self - loathing due to his werewolf condition. He might think he's not good enough for Tonks and that she'd be better off without him, fearing that his lycanthropy could bring danger or a difficult life to her.
Love against all odds is a very common theme. Given Remus' condition as a werewolf, they face a lot of opposition and prejudice. Fanfictions often explore how their love overcomes these difficulties.
There are also authors who are really good at character development in their fanfictions. Take 'TonksTales' for example. They create stories where Lupin and Tonks' characters are very true to the original books but also have new and interesting facets added. They might explore Lupin's insecurities in a new light or show Tonks' Metamorphmagus abilities in unique situations. Another great author could be 'RemusAndNymphadora' who writes stories that are often set in different time periods of the 'Harry Potter' world related to Lupin and Tonks.
Definitely Harry Potter. He was a good friend of Lupin and Tonks, so he could be like an uncle figure to the baby. He could visit often and share his own experiences growing up in the wizarding world, giving the baby some valuable advice.
