One challenge could be distance. Since Ash is often on his journey traveling from region to region, being away from Alola Lily for long periods might put a strain on their relationship. For example, he might miss important events in her life or she might feel lonely without him.
In the fanfiction, Alola Lily could be a Pokémon researcher. Ash visits her research center and they start working on a project together, like studying the evolution of a certain Alola Pokémon. As they spend long hours observing and documenting, they start to have deeper conversations. They discover they both have a passion for understanding Pokémon better, and this common ground leads to a romantic relationship. Their love might be tested when Ash has to leave for another region for a Pokémon tournament, but they find ways to stay connected.
One way to develop their characters further is through a story arc where they are separated from their Pokemon for a while. Ash, who is so used to having his Pokemon by his side, would have to rely on his own wits and survival skills. He might discover new strengths within himself. Lily, too, would be in a similar situation. When they reunite, they could share their experiences and have a newfound respect for each other. Also, they could get involved in a diplomatic mission in the Pokemon world, representing different regions. This would require them to be more diplomatic and understanding of different cultures, which would add new layers to their characters.
One idea could be that Ash and Lily team up to explore a new, uncharted region in the Pokemon world. They encounter rare Pokemon and have to figure out how to catch them together. Another plot could involve them facing a powerful villain who is threatening to destroy a Pokemon sanctuary, and they must use their combined skills and the help of their Pokemon to stop the villain. Maybe they also discover a new type of Pokemon evolution that has never been seen before during their adventures.
Another one is 'Snape and Lily: A Different Path'. In this story, it takes a different turn from the canon. It explores a world where they are more open about their feelings and how it could have changed the whole wizarding world's dynamic. It's a really interesting read for those who love exploring this relationship.
Well, a lot of fanfictions depict Snape's love for Lily as a silent, internal struggle. He doesn't always show it outwardly, but it's always there, burning inside him. Some stories show how his love for her makes him protect Harry, not because he likes Harry, but because Harry is a part of Lily. This love is also sometimes shown as a complex emotion that is intertwined with his sense of self - worth. He feels unworthy of her love, but still can't let go of his feelings, and this internal conflict is explored in great detail in many fanfictions.
One common theme is redemption. Severus has made some mistakes in his life, and in these fanfictions, Lily's love can be seen as a way to redeem him. Another theme is the power of unrequited love turned into something more. For a long time, Severus loves Lily from afar, and when she falls for him, it's like a transformation of that love.
A great fanfiction could be about their courtship. James could write her love letters filled with his thoughts and feelings. Lily would keep these letters hidden away, reading them when she was alone and slowly falling more in love with him through his written words.
One common theme is unrequited love. Since in the original story, their relationship was complicated, fanfictions often play with the idea of Snape's love being unreturned for a long time. Another theme is redemption. Snape's actions are sometimes seen as a way to redeem himself in Lily's eyes.
Well, I've come across a few. Some are really creative, imagining unique relationships between Ash and Giratina. However, the quality can vary a great deal. Some might focus more on the adventure aspect with a touch of their relationship, while others are more centered on the romantic side.
