One interesting idea could be the unique leadership styles of female primarchs. They might bring a more collaborative and empathetic approach compared to their male counterparts in the fanfiction. For example, they could focus on building stronger communities within their legions rather than just military might.
Some fanfictions might explore the cultural impact of female primarchs. They could introduce new values and traditions to the Imperium. For instance, they might promote art and knowledge preservation more than the war - focused male primarchs, thus changing the overall face of the Imperium in the fictional world.
Perhaps a key idea in this fanfic is the mystery surrounding the lost primarchs. Their very existence being a secret could be used to create a sense of intrigue. The fanfic might explore how rumors and half - truths about them spread among different factions, and how these rumors influenced the actions and beliefs of various characters.
Some fanfictions might center around the battles between different Primarchs. For instance, the confrontation between Horus and Sanguinius. In these stories, the authors often delve into the tactical aspects of their warfare as well as the emotional turmoil of the Primarchs. Additionally, there are fanfictions that show the Primarchs interacting with normal Space Marines in unique ways, perhaps mentoring them or learning from them in some cases.
Another concept is the potential power they might have had. Given that the known primarchs were incredibly powerful, the lost primarchs could have had unique abilities that would have changed the course of the Warhammer 40k universe. For example, they might have had a different approach to dealing with the xenos threats, which could have led to a very different state of the galaxy.
There's a fan - created female primarch called Selene. The writer has given her a complex personality. She is both a fierce warrior and a diplomat, which makes her character very appealing in the fanfiction world.
Ava is also quite popular. She is usually written as a brilliant strategist. Her fanfiction stories often involve outsmarting her enemies through complex and innovative battle plans. She is seen as a symbol of female intellect in the world of the primarchs.
Well, perhaps in this fanfiction, the female is the only one who can hear a special sound from the Toothcup when she hiccups. This sound could be a call for help from an ancient spirit trapped within the Toothcup. She then embarks on a journey to free the spirit, facing various challenges along the way. The hiccup becomes a key element in her communication with the Toothcup and the spirit.
One idea could be exploring the relationship between the female character and SCP 1471 from a psychological perspective. How does she deal with the constant presence of this entity? Another could be a story where she tries to find a way to communicate with SCP 1471 in a non - threatening way. Maybe she discovers some hidden abilities or motives of SCP 1471 that no one else has.
One interesting idea could be a story where female Goku and Broly have to team up against a common enemy that neither could defeat alone. Their different fighting styles, Goku's more agile and Broly's brute strength, would create an interesting dynamic in combat.
One idea could be a story about a female Enderman who is different from the others. She might befriend a player and help them navigate the End dimension in a unique way. Another could be a fanfiction centered around a female Villager who has special powers and uses them to protect her village from raiders. Maybe a story about a female Witch who decides to use her magic for good instead of her usual mischievous ways.
One idea could be exploring her relationships with the other characters in more depth. For example, how she bonds with Yosuke, Chie, and Yukiko outside of the main plot. Another idea is to create an alternate universe where she has different Persona abilities or a different backstory that changes the way she approaches the Midnight Channel mystery.
