* Implicitly defective Ossmodula
* Implicitly enhanced Progenoids:
** They have the lowest gene-seed rejection rate, which enables them to replenish their huge number of casualties with an even higher number of recruits.
** Minor Ossmodula mutation ''sometimes'' causes limbs to twist and deform as the marine grows really old (we're talking hundreds of years to millennia) - this is usually dealt with by replacing limbs with bionics, or cutting them off and placing the cripple into a Dreadnought, Helbrute, or some weird custom made dreadnought-esque walker, since due to their specialty and organization only high-ranking officers can survive for so long, and they surely ain't going to suffer from the "Crazed" rule.
** Below average resistance rate to Bionics.

Especially noteworthy for the Iron Warriors considering they reside in the Eye Of Terror, there has been little mutation in their gene-seed as well. Those that do suffer mutation simply replace their mutated limbs with cybernetics. However, there may be some unknown issue which caused them to be afflicted with the [[Obliterators|Obliterator Virus]] (or was it they who made it? It's been confirmed Perturabo and Mortarion worked together on the obliterator virus) More easily - the first ones originated from them.

However, this is rendered null by the fact they are the [[/d/|sick]] [[Honsou|fucks]] behind the [[Daemonculaba]]. Due to its nature, the women themselves may have the gene-seed organs implanted (among other things), or at least the DNA required to be able to quickly grow the organs into a child stuck in their wombs. While the poor, innocent, scared kid inside can become a skinless abomination/mutant, they will normally emerge a genetically stable, gene-seed uncorrupted [[grimdark|skinless adult SPHESS MAHREEN with the mind of that same scared child]]. Suffice to say, this is a sick way of getting to [[Female Space Marines|FEMALE SPHESS MAHREENS]], and is [[Extra Heresy|DOUBLE HERESY]].
