There could be many interpretations if this is a fictional or fan - created story. Maybe 'kakyoin' is a character in a particular universe, like a game or a comic, and the idea of laying an egg is some sort of strange or magical event within that context. But without more information, it's hard to say for sure.
The concept of a'superior' Pokemon laying an egg in fanfiction could be related to a unique power - up or transformation. Maybe the act of laying the egg is not a normal reproductive process but a way for the Pokemon to transfer its power or knowledge. For example, the egg could contain the essence of the superior Pokemon's abilities and when it hatches, it gives rise to a new entity with combined powers. This would add an interesting twist to the Pokemon fanfiction story.
Others could be excited. They might see it as an opportunity for a new and powerful Pokemon to join their team or be part of their world. They would likely start making plans to protect the egg and ensure its safe hatching, perhaps even researching about it to find out what kind of Pokemon it might become.
One common theme is friendship. Since Kakyoin is part of the JoJo's crew, fanfiction might explore her friendships with other characters like Jotaro, in a more in - depth way. Another theme could be her abilities. Writers may focus on how she uses her Hierophant Green in different situations.
A common theme could be the exploration of an unlikely relationship. Since they are from the same universe but not the most obvious pairing, it makes for an interesting dynamic. Another theme might be the characters' growth within the relationship, as they come to understand each other better.
To be honest, I haven't come across a 'Harry Potter lays eggs' fanfiction myself. Fanfiction writers often come up with some really unique ideas, but this seems like a very odd and perhaps not very likely concept. It could potentially exist in the far reaches of the Internet where the most unusual fanfictions are found, but I can't say for sure without a more extensive search.
It's hard to say. There are so many Pokemon fanfics out there. This one, with its rather unorthodox idea of Ash laying Pokemon eggs, may not be mainstream popular. However, within certain circles of very creative and adventurous Pokemon fans who enjoy exploring unusual storylines, it could have some popularity.
Sure. You can also check out fanfiction.net. There may be some stories there that feature a female Kakyoin. However, you might need to do a bit of searching and filtering as the site has a large volume of content. Look for tags related to Kakyoin and female characters to narrow down the results.
