Her growth from a rookie to a battle - hardened hero is another common thread. Some fanfictions also focus on her interactions with different alien species, exploring cultural differences and how she overcomes barriers to form alliances. There are also fanfictions that delve into her past, uncovering secrets that shape her character and her actions in the present.
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.
