Perhaps there's a plotline where her half - alien nature makes her the key to a major intergalactic conflict. She could have knowledge or abilities that both sides are vying for. For example, she might be able to communicate with an ancient alien race that holds the secrets to a powerful energy source. This would put her in a dangerous position as she tries to navigate between the different factions without getting caught or killed.
There might be a villain who is either a human supremacist trying to eliminate her because of her alien blood, or an alien warlord who wants to use her for his own gain. This villain would constantly be a threat to her and her friends, creating a lot of conflict and drama in the story.
A third plotline could be centered around a misunderstanding. Suppose Shepard overhears something about Ashley that she misinterprets. This causes a rift between them for a while. But as they both realize that they can't be without each other, they work through the misunderstanding, and their relationship becomes even stronger as a result.
One interesting aspect could be the exploration of unique cultural blends. Since Shepard is part Asari, there might be a combination of human and Asari values, traditions, and ways of thinking. For example, the Asari are known for their long lifespans and strong biotic abilities. In the fanfiction, Fem Shepard might have a different perspective on life and combat due to her Asari heritage.
One interesting aspect is the new abilities she might have. For example, she could have some alien - like senses or physical strength. Another is the different relationships she could form. Alien species might see her as one of their own to some extent.
There are also fics that focus on what happens after the main events of the Mass Effect games. Maybe they retire together or continue to fight for galactic peace in a different way. One long - form fanfiction delved into their post - war life, where they had to deal with the aftermath of the Reaper destruction and rebuild a new society while also maintaining their relationship.
One possible plotline could be Naruto discovering his half - dragon heritage and struggling to control the new powers that come with it. For example, he might accidentally set things on fire with his dragon breath when he gets angry.
Another interesting plot could be Bella falling in love with someone who is completely unaware of her half - demon status. This would create a lot of tension as she tries to keep her true nature a secret from her love interest. At the same time, she might also have to protect her loved one from the darker elements of the demon world that are attracted to her because of her heritage.
One idea could be exploring how her half - Asari heritage affects her biotic abilities. Maybe she has a unique way of using biotics that combines both human and Asari techniques. For example, she could be able to create biotic shields with a different appearance or strength compared to a full - human or full - Asari. This could lead to interesting scenarios in combat where she surprises her enemies with her unorthodox biotic skills.
One interesting plotline could be Hermione's discovery of new spells related to the Half - Blood Prince's notes that she uses to outwit the Death Eaters. For example, she might find a unique defensive spell that saves her friends during a battle.
One interesting plotline could be Hermione struggling to control her new vampire instincts while still trying to be the top student at Hogwarts. For example, she might have a hard time resisting the urge to drink blood during her classes or exams, adding a whole new layer of difficulty to her academic life.
