==== Luna Wolves/Sons of Horus (XVI Legion) ====
{{Main|Black Legion}}
* Implicitly defective Ossmodula, causing increased cosmetic similarity to their Primarch.
* Implicitly defective Biscopea, causing increased cosmetic similarity to their Primarch.

No real defects, but the tendency for members to look more like their [[Horus|Primarch]] is more pronounced (and possibly more frequent) than it is for members of other legions to resemble their own respective Primarchs. [[Horus Aximand|"Little Horus" Aximand]] was the most notable example of this, but by no means the only one. This gives extra meaning to the "Sons of Horus" thing. In fact, before the Luna Wolves were renamed the Sons of Horus, Luna Wolves that resembled Horus in appearance were known as "Sons of Horus". Ten thousand years in the Eye of Terror has left the Legion's gene-seed more unstable. However, we do know that new Black Legionaries are inducted constantly (seeing as they are the primary generic Chaos Space Marines faction), so its a good bet a large part of theirs is still usable [[grimdark|and that generations of children for millennia to come will be torn away from their parents and families, unfortunate enough to live in the Eye Of Terror, to be inducted into the Legion.]] Furthermore, given that they frequently "recruit" from other chapters and legions with the only real requirement being loyalty to [[Abbadon]], it's not always easy to tell which Black Legionnaires are descended from Horus and which are from other Primarchs, outside of the aforementioned lookalike business.
