In this type of fanfiction, the main characters associated with the 11th Primarch can vary widely. There could be Inquisitors who are either investigating the 11th Primarch or working with him. These Inquisitors could bring their own motives and agendas. Tech - Priests might also be important characters as they could be interested in any new technology or knowledge that the 11th Primarch might possess. And of course, there could be Chaos Lords who see the 11th Primarch as a threat or an opportunity for their own dark purposes.
I'm not entirely sure as I haven't read it in detail. But generally, it might be about the journey, battles, and character development of Alpharius as a primarch.
There are fanfictions that focus on the Primarch Magnus the Red. For example, a story could be set during his time on Prospero, delving into his study of the warp and how his actions were misinterpreted by the Imperium. It could also show his complex personality and his love for knowledge.
One main theme is power. Combining the powerful abilities in Naruto with the might of the Primarchs often leads to exploring different levels and types of power. Another theme is identity. Characters may struggle with their new identities when influenced by Primarch - like qualities.
First, do a lot of research on the existing lore of the primarchs. Know their personalities, their backstories, and their relationships. For example, if you want to write about Vulkan, understand his connection to Nocturne and his forgiving nature.
One possible element could be the power - up. Just as primarchs are often extremely powerful, Percy might gain new powers or enhance his existing ones in this fanfiction. Another element could be the leadership aspect. Primarchs are leaders, and Percy might be put in a position where he has to lead in a more primarch - like way, perhaps leading a group of demigods in a more structured and strategic manner.
Well, it depends on how it's written. If it's a fanfiction, then it's someone's creative take on merging Percy Jackson with the idea of a primarch. Maybe the author saw some similarities between Percy's journey and the grandeur associated with primarchs. However, it could also be a really out - there concept that takes Percy in a completely different direction than his original story.
I'm not sure of the exact title, but there's a 'naruto primarch fanfic' that combines the rich lore of Naruto with the grandeur of the Primarchs. It has detailed descriptions of how the Primarch - like qualities are integrated into the Naruto characters. For example, some characters might show enhanced leadership or combat skills similar to the Primarchs, and the fanfic weaves a story around these changes in a very engaging way.
Since it's about Alpharius, his brothers - the other primarchs - could potentially make appearances. And within his own legion, there may be lieutenants or advisors who are key characters. Additionally, any adversaries that he faces, whether they are from alien races or other parts of the Imperium, could be main characters in the sense that they drive the plot forward through their conflicts with Alpharius.
