A plotline could revolve around the female Nidus trying to understand her own identity. As an Infested Warframe, she struggles with whether she is still the person she was before or if she has become something entirely new. She could embark on a journey of self - discovery, meeting different characters from the Warframe universe who either help or hinder her in this process. This could involve her visiting different planets and encountering various cultures within the game's lore.
The female Nidus might also be part of a prophecy in a fanfiction. It could be foretold that she will either bring about the end of the Infestation or cause it to spread uncontrollably. This leads to different factions within the game trying to either protect or kill her. She has to navigate through this web of politics and power struggles while also coming to terms with her own role in the fate of the Infestation.
One possible plotline could be that the female Nidus is on a quest to find a cure for the Infestation. She believes that there is a way to reverse the process that turned her into what she is. Along the way, she has to face off against other Warframes who fear her and the power she wields. Another plotline could be her being hunted by the Corpus or the Grineer who want to use her unique abilities for their own evil purposes.
There could be many interesting aspects in a female Nidus fanfiction. Maybe it could explore her origin story. Since Nidus is a unique and somewhat grotesque yet fascinating Warframe, a female version might have a different backstory related to the Infestation. For example, she could have been a female Orokin scientist who was accidentally infected and instead of succumbing to it, she learned to control the Infestation in a way that no one else could, leading to her becoming the female Nidus.
The fanfic could be set in a post - war scenario. Nidus and Saryn are part of a group trying to rebuild the war - torn areas of the Origin System. Nidus is using his powers to purify and transform the infested areas into something more habitable, while Saryn is using her toxins to destroy any remaining harmful substances. At first, the other members of the group are a bit wary of their powers. But Nidus and Saryn prove their worth. They also start to develop a special connection as they work side by side, with Nidus being intrigued by Saryn's scientific approach to her powers and Saryn being fascinated by Nidus's biological mutations.
A possible plotline could be the Warframe human trying to adapt to the different species and cultures in Mass Effect. They might struggle with the galactic politics and the various factions.
To write a great Warframe Nidus x Saryn fanfic, start with a strong opening. Maybe describe a battle scene where they first meet in the middle of chaos. Then, develop their relationship gradually. Have them exchange banter about their different ways of fighting. For example, Nidus could tease Saryn about her 'slow - spreading' toxins compared to his fast - acting infestation. In terms of setting, use the rich lore of Warframe. You could set it in the Void, where strange things happen to their powers. Also, don't forget about the other characters in the Warframe universe. Maybe they have to interact with Teshin or the Lotus at some point, which adds more depth to the story.
A good female nidus fanfiction could be centered around her relationship with other characters in the original story's universe. For instance, how she interacts with a mentor figure and how that relationship helps her grow. It could explore her emotions and development in a more in - depth way compared to the original work.
Maybe a story where female Gaara decides to participate in the Chunin Exams in Konoha. Naruto, being a veteran of the exams, offers to help her train. As they train, they get to know each other better. Naruto helps Gaara overcome her insecurities, and Gaara helps Naruto understand the pain of being an outcast in a different way. This mutual understanding blossoms into love.
One idea could be a story where Nidus and Stalker team up to face a common enemy. They could start off as reluctant allies, gradually learning to trust and respect each other's skills.
One interesting story could be about an operator who forms a deep bond with their Warframe during a difficult mission. The operator discovers new abilities of the Warframe that were previously unknown, and together they overcome a powerful enemy. For example, the operator might find that their Rhino Warframe can perform a special charge move in a particular situation that saves them from a horde of enemies.
In another scenario, the fanfiction could be set in a post - apocalyptic world. Shirou and the female archer are part of different survivor groups. They meet during a scouting mission. At first, there is tension between them due to the rivalry between their groups. However, as they realize that they share a common love for archery and a desire to rebuild the world, they decide to work together to bring peace and restore the art of archery in the new world.
One possible plotline could be Cell adjusting to his new female form. He might face different reactions from the other Z - fighters. For example, some might be more sympathetic while others are more suspicious.
