Editing Gene-seed (section)

==== White Scars (V Legion) ====
{{Main|White Scars}}
* Tendency to do whatever they fancy.
* Unrestrained love towards doing [[PROMOTIONS|strange things]] to engines buffing their bikes and battleships to ride into battle while riding into battle.
* A defect called "Chogorian Savagery". Basically it's diet Black Rage, born from when Mortarion almost killed their primarch during the Siege of Terra. This flaw appears in 2 stages:
** Stage 1 - A Moment Unrestrained: The Battle-Brother starts [[RAGE|flipping out mid-battle]] for brief periods, often without realising he's doing so until one of his brothers tells him to take a chill pill.
** Stage 2 - Suppressed Rage: The Battle-Brother becomes extremely prone to outbursts of temper and quick to anger.

===== Mantis Warriors =====
{{Main|Mantis Warriors}}
* Possibly Melanchromic Organ as all have green eyes and black hair of their Primarch.
* Malfunctioning Preomnor gland (possible explaining the cause of the gene-flaw of the other White Scars chapters)

Their mutation called "Battle Haze" causes their Preomnor gland to secrete a potent neuro-toxin that permanently changes the Astartes' physiology; the Space Marine is overcome by a feeling of the need for forgiveness for his many sins and shortcomings and a dramatically increased reverence for the Emperor; and increases his neurological reaction rate to that only achieved in near-precognitive states by most psykers and increases his already superhuman strength to a great extent. However, this physiological change is irreversible and the Astartes' sight becomes tunnelised to the point of no longer being able to notice anything in his field of view that is not a target or a foe. Much like the [[Death Company]] of the Blood Angels, the Mantis Warriors organize Battle-Brothers who have been lost to the Battle Haze into specialized units called "Mantis Religiosa".

===== Destroyers =====

* "Chogorian Savagery" turned up to 11. To the point even other White Scars question the stability of the Destroyer's geneseed. More evidence that the flaw stems for the gene-seed of the White Scars, and not from what population they are pulled from. Probably at least a bit psychological and genetic memory related, what with the most psychotic Scars forming this Chapter in the Second Founding.
