Another popular interpretation is that the lost primarchs were secretly working against the Imperium all along. This could involve them allying with chaos or other enemies of the Imperium, and their disappearance was part of a long - term plan to undermine the Imperium from within. Fanfictions based on this idea often involve complex plots and political intrigue within the Warhammer 40k setting.
Horus is often very popular in fanfiction. His fall from grace is a major event in the Warhammer 40k lore, and many fanfiction writers like to explore the reasons behind it more deeply. They might create alternate timelines where he doesn't fall or explore his relationships with other Primarchs in more detail.
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.
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.

Some of the Warhammer 40k characters might also be popular in these crossovers. For instance, the Ultramarines are well - known and could be paired up with Naruto characters. Their sense of honor and combat prowess can create interesting interactions. The way they would view Naruto's powers and vice - versa can lead to some really engaging storylines.
In Warhammer 50k fanfiction, characters like the Sisters of Battle are quite popular. They are strong, devout warriors, and their stories of faith and combat can be really inspiring.
