Well, a key element would be the exploration aspect. Newt was always out in the wild, looking for new creatures or trying to help the ones in need. So in the fanfiction, the main character could be exploring places like the Forbidden Forest or the mountains around Hogwarts. Another important part is the way the character deals with the challenges of taking care of the creatures. There might be a situation where a creature is sick, and the character has to find a cure using their limited resources, just like Newt did so many times. And of course, the character's unique relationship with each creature, showing that they see them as more than just beasts but as friends with their own personalities.
First, the love for magical creatures is essential. Just like Newt, the character in the fanfiction should have a deep understanding and respect for all kinds of beasts. Second, a magical suitcase or some kind of container to hold the creatures would be a great addition. Also, interactions with other characters from the Harry Potter world where the protagonist shares their knowledge about the creatures. For example, having a conversation with Hagrid about a new type of dragon he's never seen before.
