Perhaps in this fanfiction, Ash's transformation into a Zoroark is a result of a wish gone wrong. He made a wish at a mysterious Pokémon shrine, not realizing the consequences. As he turns into a Zoroark, he meets a group of wild Zoroark who are initially hostile but then sense that he's different. They take him in and teach him their ways. Ash uses his new - found Zoroark abilities and his knowledge of Pokémon battles to help the Zoroark group against a common enemy, all while trying to find a way to reverse the transformation.
One possible plot could be that Ash is in a strange, enchanted forest. He somehow gets caught in a magical spell that starts to transform him into a Zoroark. As he changes, he begins to experience the world from a Zoroark's perspective. He discovers new powers and instincts, like the ability to create illusions to protect his friends from approaching danger in the forest. His Pokémon friends are initially confused but then realize it's still Ash inside.
His other Pokémon like Bulbasaur and Charmander would also be startled. They might gather around Ash - Zoroark and sniff him out to make sure it's still him. They could be a bit hesitant to follow his commands at first because they're not used to his new form. However, as they see that Ash's spirit is still there, they would gradually start to trust and follow him again, and they would work together to figure out how to turn him back.
One possible plot could be that Ash is on a journey in a mysterious forest. He stumbles upon an ancient and powerful crystal. When he touches it, a strange energy envelops him and he starts to transform into Mew. As Mew, he has to adapt to his new form. He discovers he can fly and communicate with other Pokémon in a different way. He then uses his new abilities to help his Pokémon friends who are in trouble in a nearby cave, fighting off a group of powerful rogue Pokémon.
One possible plot could be that Ash is transformed into a rare and powerful Pokemon like Mewtwo. He then has to navigate the Pokemon world from a different perspective. He discovers new abilities and strengths he didn't know about before. And he uses his knowledge of being a trainer to communicate with other Pokemon and form alliances to face the challenges that come his way.
The character development of both Ash and Zoroark is also a big part. Ash may learn new ways of training and understanding Pokémon from Zoroark, while Zoroark might become more open and friendly under Ash's influence. In some fanfictions, Zoroark's backstory is explored in depth, which gives more depth to their relationship with Ash and the overall story.
One plot idea could be that Ash discovers a Zoroark that has been separated from its pack. He decides to help it find its way back home while facing various obstacles along the way, like other Pokemon who are territorial. Another could be that a Zoroark, in its disguised form, befriends Ash without him knowing it's a Zoroark at first. Then when he discovers the truth, they have to work together to save a forest from a group of poachers.
One possible plot could be that Ash is hit by a strange new type of Poké - ball created by a mad scientist. This ball has the power to transform trainers into Pokémon. Ash wakes up to find himself in the body of Pikachu. At first, he's disoriented but then realizes he can communicate with his other Pokémon in a new way. He teams up with Pikachu (who is now acting a bit like Ash) and they go on an adventure to find the scientist and reverse the transformation.
A new, powerful and evil Pokemon trainer could be the antagonist. This trainer might be jealous of Ash's new form and powers as a Pokemon and wants to capture him to use his powers for his own gain. He could set up various traps and battles to try and subdue Ash.
If we assume that the 'lemon' aspect is not about adult content but rather some sort of unique or tangy element in the story. It could be that the fanfiction gives a very different take on Ash and Zoroark's relationship. Maybe Zoroark has some special abilities that help Ash in a way that is not shown in the original Pokémon series. The story could be about how they overcome difficulties together, with Zoroark's mysterious nature adding an extra layer of intrigue to their interactions.
Yes, there could be. Many fanfiction writers might be interested in creating stories centered around Ash within the context of the Zoroark world. It could explore their relationship, adventures they might have together, or how Ash might interact with a Zoroark in unique ways.
One idea could be that Ash catches Zoroark in a unique way. Maybe Zoroark is disguised as a Pokémon that Ash has been longing to catch for a long time. When Ash discovers the truth, instead of being angry, he is intrigued by Zoroark's intelligence and uses his own skills and the bond with his other Pokémon to earn Zoroark's trust and catch it.
