Is it appropriate to write 'ash and misty sex fanfic'?

No. Writing sexual fanfics about fictional characters, especially when they are often associated with a younger audience in their original works, is inappropriate and violates ethical and moral standards.

No. Creating fanfic with sexual content involving Pokémon characters is inappropriate. Pokémon is a family - friendly franchise mainly targeted at younger audiences, and such content violates the spirit of the series and ethical standards.

I'm sorry, but creating or promoting fanfics with sexual content is unethical and often violates the terms of use of many platforms. So, I cannot support or recommend such content.

In some fanfics, Misty might be portrayed as betraying Ash for power. For example, if there is a powerful trainer who offers Misty a chance to become an even greater trainer, but at the cost of leaving Ash behind. She could be tempted by the allure of advanced training techniques or rare Pokémon that this new opportunity presents.

One appropriate topic could be their adventures together in different regions. They could face new and powerful Pokémon, and how they strategize and overcome challenges as a team.

It's doubtful that it's a popular fanfic. Popular fanfics usually tend to build on the positive aspects of the source material, like the friendship or adventure between characters. A concept where Ash kills Misty is so out of the ordinary and negative that it probably doesn't appeal to a wide audience. However, there might be a small niche of readers who are interested in very dark and alternative fanfics, but overall it's not likely to be popular.

Well, a fanfic about Ash, Misty and Charizard in Kalos could be really exciting. Maybe it could start with Ash arriving in Kalos with Charizard, and then Misty comes to visit. They could explore the unique Pokémon in Kalos together, and Charizard might have some interesting battles against the local strong Pokémon. It would be a great story to show their friendship and adventures in a new region.

One idea could be that Ash and Misty visit Unova for a Pokemon tournament. They meet new friends and face new challenges together. Misty could use her water - type Pokemon in creative ways against the Unova Pokemon's unique types.

Writing such fanfiction that involves sexual content is inappropriate and goes against ethical and moral standards in most cases. Fanfiction should generally focus on positive, creative, and non - explicit relationships and stories.

It is not acceptable at all. Ash and Misty are iconic characters from a popular franchise that has a global following. The franchise promotes values like friendship, perseverance, and respect. Adult fanfiction about these characters would be inappropriate as it would deviate from the intended values of the Pokémon brand and could also make the franchise less appealing to its core audience, which includes many children and families.
