Maybe a plot where Ash's Pikachu gets lost and Gwen, using her magic skills, helps Ash track it down. Along the way, they encounter some new and strange Pokemon species that are attracted to Gwen's magic. They then have to figure out how to get Pikachu back without causing any harm to these new Pokemon.
Well, you could write a fanfiction about Gwen's past. For example, how she felt when she first discovered her powers. Was she scared? Excited? You could also write about her relationships within the family, like her interactions with her parents or other relatives. And don't forget about her friendships. Maybe she has a falling - out with one of her friends and then has to work hard to fix it in the fanfiction.
Maybe there's a situation where the worlds of Greek mythology and the alien species from Ben 10 (where Gwen is from) start to merge. Percy and Gwen have to figure out how to stop it before chaos ensues. They might face challenges like dealing with gods who are intrigued by the alien technology and aliens who want to harness the power of the Greek gods.
Ash is very determined and passionate about Pokemon. Gwen is intelligent and has a strong sense of justice. Their personalities could interact in a way that Ash's enthusiasm rubs off on Gwen when it comes to exploring the world of Pokemon. Gwen's rational thinking could also help Ash make better decisions in his Pokemon battles and adventures.
A possible plot is that there is a threat in both worlds at the same time. Gwen and Harry have to team up, with Gwen using her alien powers and Harry his magic. They travel between the two worlds, trying to find the source of the threat. Gwen's Ghostfreak form could be used to spy on the enemies in the Harry Potter world without being detected easily.
One idea could be a crossover where Naruto and Gwen end up in the same dimension. They might initially be at odds, with Naruto being all about ninjutsu and Gwen having her alien - based powers. But as they face a common enemy, like an evil alien - ninja hybrid, they learn to work together. Their different fighting styles and outlooks on life would make for an interesting dynamic.
Perhaps in the fanfiction, Cynthia could be mentoring Ash in some advanced Pokemon battling techniques. Ash, being eager to learn, follows her guidance and in the process, they develop a deeper bond. This could lead to them exploring new regions together in search of rare Pokemon for training.
One interesting plot idea could be that Ash and Sakura team up to enter a special Pokemon tournament that features rare and powerful Pokemon. They have to train hard together, with Sakura's knowledge of different Pokemon types and Ash's battle experience combining to give them an edge.
Perhaps Daisy discovers a new type of Pokemon that is extremely rare, and she enlists Ash's help to study it. Along the way, they face off against a group who wants to capture the Pokemon for its power. This could lead to many adventures and battles for them.
Perhaps there's a plot where Gardenia challenges Ash to a friendly battle. But during the battle, an unexpected event occurs like a sudden storm or the appearance of a wild, powerful Pokemon. They then have to put their battle on hold and cooperate to deal with the situation. Afterward, they realize that they have a lot more in common than they thought and start to explore a romantic relationship.
Sure. There are many fanfiction writers who create stories centered around Gwen Tennyson that are family - friendly. They might write about her solving mysteries, using her powers for good, or having heartwarming interactions with her family and friends. It's all about expanding on the character in a positive and appropriate manner.
