I don't think they are overly popular. Most Pokémon fans are interested in the positive aspects of the Pokémon relationships, like friendship and cooperation. Lemon fanfics, which often involve inappropriate content, are not something that the majority of the community would support or promote.
I'm not really into lemon fanfics as they often contain inappropriate content. However, if you're looking for regular latias x latios fanfics, you can check out some Pokémon fanfic websites like FanFiction.net or Archive of Our Own. There might be some well - written stories about their relationship there.
Latios and Latias are very interesting Pokémon in fanfiction. In lemon fanfiction, often their unique psychic and flying abilities might be incorporated in creative ways. For example, they could use their powers to create a special, dream - like setting for a story. However, such fanfictions also need to be in line with the general lore of the Pokémon world to seem believable.
For writing Latios and Latias' characters effectively, think about their unique abilities. Latios' speed and intelligence can be reflected in his decision - making. He could be the one to quickly come up with plans. Latias, with her camouflage ability, might be more elusive and secretive in character. In your fanfic, make their actions and dialogue consistent with these aspects. For instance, Latios could use his speed to quickly scout an area and report back to Latias. And when they interact with other Pokémon, their personalities should shine through. Latios might be more assertive, while Latias is more gentle in her approach.
Common themes in a Pokemon Latios x Latias fanfic include adventure, of course. They are powerful and fast Pokemon, so they can go on all sorts of exciting adventures. Another theme is mystery. Their psychic abilities and their somewhat elusive nature can be used to create a sense of mystery in the story. Also, the theme of friendship might be present, not just between them but also with other Pokemon they meet during their travels. For example, they might befriend a small group of Pokemon that are in trouble and help them out.
One common theme is the exploration of their unique bond. Since they are siblings in the Pokémon world, fanfictions might delve into how this bond can be both platonic and have hints of something more in a romantic or emotional sense.
Well, a good plot could be that Latios gets injured and Latias has to go on a quest to find a special healing item for him. Along the way, she meets other Pokémon who either help or hinder her. Or, they could be caught in the middle of a battle between two different Pokémon factions and have to use their unique abilities to bring peace. Also, a plot where they explore a new, uncharted region together and encounter strange new Pokémon and phenomena.
Well, in a Pokemon Latios x Latias fanfic, you can expect a story full of adventure. It might focus on their unique bond as siblings or their powers. Maybe it'll have them teaming up against a common enemy in the Pokemon world, like a powerful villainous team. It could also explore their relationship with trainers or other Pokemon in their environment.
There is a fanfiction called 'Latias and Latios: Twin Souls'. In this story, it focuses on their origin as twins. It details how they communicate without words and how their powers complement each other. It's really interesting to see their relationship unfold in different adventures.
One common theme is adventure. They might go on a journey together, facing various challenges in the Pokemon world. Another theme could be friendship, showing how their unique bond as siblings or partners helps them through tough situations.
