One common element is the adaptation of Jungle Book characters as Pokemon or Pokemon trainers. For example, Mowgli could be a trainer with unique Pokemon. Another element is the jungle setting, which is often a key part of the story, with Pokemon interacting in a jungle environment much like in the Jungle Book. Also, themes of friendship and survival are common, as Pokemon and their trainers or just Pokemon among themselves have to work together to survive in the jungle, just like in the Jungle Book.
Well, one aspect of the secrets could be about the unique powers the Aura Guardian Pokemon possess. Maybe they have some hidden abilities that are only revealed in special situations within the fanfiction.
A simple fanfiction could be about a young journalist who is trying to expose Team Galactic's secrets. They follow the team around discreetly and document their actions, all while trying to avoid getting caught by the team's security.
Some fanfics might explore the painful secret of a Pokemon's origin. For example, a Pokemon that was created through an unethical experiment. It has to live with the knowledge that it was not born in a natural way, which can be a very heavy burden for it. This kind of secret can add a lot of depth to the story.
Perhaps the secrets lie in the training methods of the Aura Guardian Pokemon. They might have a unique way of training that is different from other Pokemon, which could be a big secret.
I'm not sure specifically as it depends on the particular fanfic. But it could be a well - known Pokemon trainer like Ash, who discovers some painful secrets about the Pokemon world. Or it might be an original character created by the fanfic writer.
Some fanfictions suggest that the gym leaders are part of a conspiracy. They might be working together to keep certain trainers from advancing too quickly in the league. They use their battles not just to test the trainers' skills, but also to weed out those who might pose a threat to their hidden plans.
One great Pokemon Jungle Book fanfiction is 'The Jungle Adventures of Pikachu'. In this story, Pikachu finds itself in a jungle much like the one in the Jungle Book and has to learn to survive among the wild Pokemon. It's a really fun read as it combines the charm of Pokemon with the exciting jungle setting.
Perhaps the 'painful secrets' involve the relationships between trainers and Pokemon. It could be that a trainer has a hidden agenda that is causing distress to their Pokemon, like using them for some not - so - noble experiments. This would add a dark and mysterious layer to the fanfic.
Painful secrets can make the characters more relatable. Just like in real life, when Pokemon have secrets they're hiding, readers can empathize with them. It adds an emotional layer to the story.
