One popular theme is their adventures together while dealing with magical creatures. Since Newt is a magizoologist, they often encounter various beasts in fanfics, and Tina helps him out. Another theme is their relationship development, from their initial meeting in the movies to a deeper emotional connection.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a vast collection of fanfics, and you can simply search for 'Newt Scamander x Tina Goldstein' in the search bar. Another option is Fanfiction.net, although AO3 generally has more diverse and well - organized content for this pairing.
It's a bit tricky to pin down Newt Scamander's exact age in the novel. However, we can make some educated guesses based on his experiences and the time period the story is set in. My estimate would be that he's around 23 or 24 years old.
In a fanfiction, Newt could be called upon by the Ministry of Magic to handle a dragon that has escaped from a wizarding zoo. He would have to track it down in the wild, and when he finds it, he realizes that the dragon is injured. Newt would then have to use his healing skills and his bond with magical creatures to nurse the dragon back to health while also making sure it doesn't cause too much chaos in the non - magical world. This could lead to some interesting encounters with muggles and challenges in keeping the dragon's existence a secret.
One common theme is the exploration of the magical world. Fanfics often describe Newt's adventures in different parts of the wizarding world, uncovering hidden magical places and creatures.
Perhaps there's a prophecy in the wizarding world that only a dragon rider can stop an upcoming war. Newt, being the expert on magical creatures, is sought out to be this dragon rider. He initially resists, but when he realizes the importance of the task, he embarks on a journey to find a suitable dragon. Along the way, he meets other characters who help him in his quest, and he has to learn the ways of dragon riding from scratch, which is full of both comical and dangerous moments.
The theme of friendship is often there at the start. How they become friends before developing deeper feelings. There's also the theme of the wizarding society. Fanfictions may show how their relationship is affected by the rules and expectations of the wizarding community. And of course, the theme of discovery, both in terms of self - discovery and discovery of new magical things as they are together.
One common theme could be love and affection. Since it involves a 'beso' (kiss), the fanfic may focus on the deepening relationship between Ash and Serena.
One common theme is the exploration of Newt's relationship with his magical creatures from a female perspective. For example, how a female Newt might have a different approach to taming or caring for them. Another theme could be her interactions with other characters in the Fantastic Beasts universe, like Tina or Jacob. There might also be themes related to her facing the challenges in the wizarding world as a female magizoologist, which could include discrimination or unique opportunities.
Another characteristic is that it can expand on the wizarding world that Newt is part of. It could introduce new locations or magical concepts related to his work. Also, it should have a good plot, like a mystery he has to solve or a new discovery he makes. This makes the story exciting and keeps the readers interested. For instance, a story where Newt discovers a new type of magical creature and has to figure out how to protect it. It would involve his knowledge, his courage, and his compassion for the magical world.
