Yes, there might be some fanfictions that handle this in a very innocent and non - inappropriate way. For example, it could be a magical, allegorical kind of story where the 'having a baby' is more about a special bond or creation in a very fantastical sense rather than anything improper.
One possible plotline could be that Harry discovers a magical animal that is in danger. He forms such a strong bond with it that it's like they are family. Through some magical event, they create something together that is like a 'baby' in the sense of a new magical entity that they both care for and protect.
There are various ways hunting animals can be incorporated into Harry Potter fanfiction. It could be part of a quest where the characters need to hunt a specific animal for a potion ingredient or a magical artifact. For example, a fanfic could depict Harry and his friends on a hunt for a rare unicorn, which would not only involve the physical act of hunting but also deal with the moral implications since unicorns are considered sacred in the wizarding world.
Often, in Harry Potter fanfiction, animals are hunted using magic. For example, spells might be used to track and capture them. Wizards could use the 'Revelio' spell to find hidden animals. Then, they might use a binding spell like 'Incarcerous' to trap the animal before taking it for whatever purpose they need it for, whether it's for study or for a potion ingredient.
Well, in some fanfictions, Harry Potter is good with animals because of his connection to the magical world on a deeper level. His experiences with dangerous creatures like the Basilisk might have given him an edge in understanding animals. Fanfic authors often write him as being able to sense what animals need or want. So he can help injured magical beasts or even befriend those that are usually hostile.
One interesting fanfiction could be about baby Harry's first magical experiences even before he went to Hogwarts. Maybe he unknowingly made his toys levitate when he was really young, and his aunt Petunia was terrified but couldn't figure out what was really going on.
Hermione could be a main character. She would probably be very involved in helping Harry with the baby, using her vast knowledge of magic to ensure the baby's well - being.
One possible storyline could be how Harry Potter's friends react to the news of him having a baby. They might be overjoyed and start planning all kinds of things for the baby's future.
Maybe the baby dragon is a rare species. This would attract the attention of magical zoologists and collectors. Harry would then have to deal with the ethical issues of keeping the dragon or giving it to those who claim to study it properly. He would also need to consider the dragon's own well - being and freedom.
Well, it could be that the baby dragon has some special powers. Maybe it can communicate with Harry telepathically. This would lead to some really interesting adventures as they bond and learn from each other.
