For those unaware and concerned about accuracy "Primarch" refers to set of 21 in universe characters where being one of these characters is ITSELF the definition of being a primarch. Primarchs that are dead, horribly mutated, essentially a corpse piloted by a demon (all of which happened in lore), drawn as a normal human in some au, turned into an animal by a fanartist, etc are still primarchs because they are that character.
Point being no matter HOW it's depicted, depicting one of these characters is eligible for the primarch tag. It's like saying "if I draw jesus as a normal person should it still be tagged religion?".
Some people in the fandom feel primarchs are massively over saturated and it would be damn near to filter them out when browsing given the tag limit when searching compared to "warhammer_40k -primarch", sure, this could be done via blacklisting but this also makes it harder with no account or those who are looking for primarch pictures without doing a separate search for each of them.
Though I will concede that is also about humanity itself being over saturated to some fans and its various sub factions and how traitor primarchs shouldn't necessarily be tagged "imperium of man" etc. Someone with better lore understanding of xeno factions can explain better than me. Now, two of these characters were "erased from history" in universe to allow fans to make their oc primarchs so with the exception of fanmade version of the two missing primarchs it's essentially a missing tag for posts with the following characters.
So I wanted to do (primarch name) -> primarch (collapsed for readability)
Show
imply Lion_El'jonson -> primarch
imply Fulgrim -> primarch
imply Perturabo -> primarch
imply Jaghatai_Khan -> primarch
imply Leman_Russ -> primarch
imply Rogal_Dorn -> primarch
imply Konrad_Curze -> primarch
imply Sanguinius -> primarch
imply Ferrus_Manus -> primarch
imply Angron -> primarch
imply Roboute_Guilliman -> primarch
imply Mortarion -> primacrh
imply Magnus the Red -> primarch
imply Horus_Lupercal -> primacrh
imply Lorgar_Aurelian -> primarch
imply Vulkan -> primarch
imply Corvus_Corax_(warhammer) -> primarch
imply Alpharius_Omegon -> primarch
But primarch is apperently a general tag so I get an error trying to make the BUR in the first place.
Example: the same primarch before and after being turned into a demon and an anime genderswap. The "primarch" tag is relevant in all three.

Quoting the wiki:
Major characters in the Warhammer 40,000 setting, the Primarchs were 20 beings created from scratch by the Emperor of Mankind and whose genes would be used as the basis for the biological modifications given to each legion of Space Marines. Many would die or vanish following the treason of one of their own, Horus, and the subsequent civil war. Recently, Roboute Guilliman, Primarch of the Ultramarines, has returned to the setting and is now one of its principal characters.

I also wasn't sure if it would be easier on the servers to have (primarch name) imply both primarch and the related copyright or have the name of a primarch imply the primarch tag and have that imply the copyright?
