One common theme is family. Since Andromeda is part of the Black family, these fanfictions often explore how her relationship with Harry affects the family dynamics. Another theme is redemption. Andromeda, having broken away from her dark family roots, can bring a sense of hope and change to Harry's life, which is often explored in the stories.
One great 'Harry Potter x Andromeda Black fanfiction' is 'The Black Family's Redemption' which delves into how Andromeda's relationship with Harry might change the course of the wizarding world. It has an interesting plot that combines family drama and the fight against dark magic.
In the fanfiction, Harry and Andromeda's relationship might start as a practical arrangement. However, as time passes, they begin to understand each other better. Harry sees Andromeda as a mother figure he never really had, and Andromeda sees Harry as a positive male role model for Teddy. They start to rely on each other not just for Teddy's sake but also for their own emotional support. They might have long conversations about their past losses, which deepens their bond.
Well, a 'Harry raised by Andromeda' fanfic can completely transform the original story's plot. Andromeda, being a Black, has her own connections and knowledge of the wizarding world. She can introduce Harry to different aspects of magic and magical families that he might not have known otherwise. His growth as a wizard is different. He may not rely as much on his friends for emotional support as he gets it all at home. This can change the dynamics of his friendships at Hogwarts. Also, in the battle against Voldemort, Harry may have different resources and allies due to Andromeda's influence.
A plot could involve a magical artifact from the Harry Potter universe being found in the Andromeda galaxy. The Initiative team discovers it and has no idea what it is. As they study it, they start to notice strange magical effects. Meanwhile, a group of dark wizards from the past who were banished somehow find their way to Andromeda as well and are after the artifact. The Andromeda crew has to team up with a wizard who has been following the dark wizards to stop them.
Another approach could be to bring a Harry Potter - like character into the Mass Effect Andromeda setting. This character could be a wizard who has to deal with the different species and technology. They might use their magic to solve some of the problems the Andromeda crew faces, like dealing with the Remnant or helping to heal the Initiative members in a way that normal medicine can't. They could also introduce the concept of magic to the Andromeda races, which would cause quite a stir.
The fanfiction could create a whole new plot. Perhaps it examines the consequences of this wrong identification and how it leads to unexpected alliances or conflicts, with Andromeda Potter being at the center of it all, influencing the outcome.
Yes, there are some interesting ones. You can start by looking on popular fanfiction websites like Archive of Our Own. Some stories might explore unique plotlines where Harry marries Andromeda, delving into how the wizarding world would react and how their relationship would develop. It often involves a lot of creativity from the authors, imagining different magical scenarios and character interactions.
Friendship is also a big theme. The relationships between Harry, Amelia and Andromeda are usually depicted in a way that shows how they support each other through difficult times in the wizarding world. They might be facing dark wizards or difficult magical tasks together, and their friendship is what keeps them going.
