One common theme is the relationship between the female Shepard and the geth. It could be about building trust and understanding, as the geth are an alien species in the Mass Effect universe. For example, the story might focus on how Shepard helps the geth to rebuild and in the process, they form a unique bond.
The theme of self - discovery for the female Shepard can also be present. As she is involved in the geth rebuild, she may learn more about herself, her values, and her place in the universe. This could be intertwined with her relationship with the geth, as she sees her own journey reflected in their struggle to rebuild and find a new place in the galaxy after all the conflicts they have been through.
Another theme could be the challenges faced during the rebuild process. This might include dealing with other factions in the game's universe who may not be in favor of the geth's rebuilding. The female Shepard may have to use her diplomatic skills or combat abilities to protect the geth while they are in the process of rebuilding. In some fanfictions, this could lead to political intrigue and action - packed scenes.
You can start by searching on popular fanfiction websites such as Archive of Our Own (AO3) or FanFiction.net. Use the search terms 'geth rebuild' and 'female Shepard' on their search bars to see if there are any relevant stories available.
In a fanfiction like this, the story could focus on Female Shepard's struggle to balance her Geth - influenced upbringing with the expectations of the rest of the galaxy. For example, she may face challenges when dealing with the Alliance, which has a history of conflict with the Geth. Her loyalty could be constantly tested as she tries to bridge the gap between two very different worlds.
One possible plotline could be that the Geth see Female Shepard as a key figure in the fight against a common enemy, like the Reapers. So they use their advanced technology to resurrect her to help in the battle.
In this fanfiction, Female Shepard's appearance and combat style could also be influenced by the Geth. Maybe she has some Geth - inspired augmentations that make her more formidable in battle. Her backstory would be a fascinating exploration of how a human can be raised by an alien race of machines, and how that shapes her into the hero (or anti - hero) she becomes in the story.
A plot twist could be that the Geth resurrected Shepard not fully as herself. There are hidden memories or abilities that start to surface as she goes through various challenges. These could be related to an ancient prophecy or a long - forgotten experiment.
One idea could be that the resurrected Female Shepard has to deal with a new threat that emerged during her time of 'death' and the Geth play a crucial role in helping her understand this new enemy. Maybe some of the Geth have developed new abilities during this time as well.
One common theme is her relationships, like her romantic relationships with other characters in the Mass Effect universe such as Garrus or Kaidan. Another theme is her leadership during difficult missions, showing her strength and decision - making skills.
Love and friendship are very common themes. Since they are comrades in the Mass Effect universe, many fanfictions explore how their initial friendship blossoms into something more. For example, how they support each other during tough battles.
Overcoming differences is also prevalent. Tali being a quarian and Shepard having her own human background, they have to work through various misunderstandings and prejudices. Adventure is another common theme, as they usually embark on exciting missions together in these fanfictions.
One common theme is the power of friendship that turns into love. They start as comrades in arms and gradually develop deeper feelings. Another theme is sacrifice. They are often in situations where they have to make sacrifices for each other or for the greater good of the galaxy.
