Articuno, Zapdos, and Moltres are quite common. Their elemental powers and the mystery surrounding them make for great fanfiction material. Ash might encounter them during his travels and have to either help them or face off against them in some way.
One of the Legendary Pokemon could be Giratina. Despite its somewhat dark and otherworldly nature, Giratina might be intrigued by Ash's light - heartedness and his ability to make friends with all kinds of Pokemon. Dialga and Palkia could also be part of the harem. Dialga, with its control over time, might see Ash as an important factor in the future of the Pokemon world. Palkia, in charge of space, could be interested in how Ash navigates different regions and spaces in his journey. And don't forget about Ho - Oh. Ho - Oh is a symbol of hope and might see Ash as a bringer of hope in the Pokemon world, thus joining his harem.
Arceus is quite popular. Given that it's considered the creator of the Pokemon universe in the official lore, it often has a significant role in fanfictions. Mewtwo is also very common. Its powerful psychic abilities and complex backstory make it a favorite for fanfic writers to explore. Another popular one is Lugia. With its majestic appearance and its connection to the sea, it's often a central figure in many stories.
Mewtwo is also very popular. Given its origin as a genetically - engineered Pokemon, a human could interact with it in many ways. Maybe a human scientist wants to study Mewtwo further, or a young trainer tries to befriend Mewtwo and help it come to terms with its existence and powers.
If Pokemon teleported to real life, it would be chaos at first. People would be both excited and scared. Some might try to catch them like in the games, but without Pokeballs, it'd be difficult. There could be problems with wild Pokemon causing damage to the environment or attacking people if they felt threatened.
A Pokemon scientist in real life might study real - world animals that share characteristics with Pokemon. For example, they could research electric eels as inspiration for Pikachu's electric abilities. They might also try to understand the concept of evolution in nature and how it could be related to Pokemon evolution. Additionally, they could work on creating technologies similar to Pokeballs for capturing and studying small animals safely.
There are also fanfictions where Ash catches Rayquaza. This could be set during a time when the sky is in chaos due to some dark energy. Rayquaza is drawn to Ash because of his pure heart and determination. Ash, with his usual courage, teams up with his pokemon to assist Rayquaza in restoring balance. As a result, Rayquaza allows Ash to catch it.
In real - life, pokemon scientists might be similar to zoologists or geneticists. They would study the unique characteristics of pokemon, like their abilities and evolutionary patterns. Just as zoologists study animals in our world, these pokemon scientists would need to understand pokemon habitats, diets, and social behaviors. Maybe they would work in special research facilities with high - tech equipment to analyze pokemon DNA or study their energy forms.
When Pokemon teleport to real life in a fanfic - like situation, humans would have diverse reactions. There would be those who see it as an opportunity for adventure and exploration. They would set out to discover new Pokemon species in the real world. However, many would also be worried about the potential danger. Governments would need to step in to ensure public safety, and there would be a lot of public debate about how to co - exist with these new arrivals from the Pokemon world.
A Pokemon scientist could contribute to society by inspiring new forms of conservation. If they study Pokemon - like traits in animals, they can raise awareness about protecting those species. For example, if a certain animal has a special ability similar to a Pokemon, it might draw more attention to its conservation needs.
