Editing Negators (section)

=Gene-seed=
For much of the Great Crusade, the Negators' gene-seed remained relatively pure. Reflecting their Primarch's prodigious height, there is a trend towards a taller average height and leaner build among the Negators. Other than this, Aodhán's gene-seed was mostly unremarkable until his Legion's entry into the Heresy.

===Warp-Spasm===
With time, a specific flaw has appeared in the Negators' gene-seed. A select few of their number, when in the height of rage or excitement, can experience a burst of uncontrollable, intense mutation. The agony of the change sends them into a ferocious berserker state known as the warp-spasm. When the spasm subsides, most outward mutations gradually normalize, but each time a Legionnaire enters the rage they retain some sign of it - jagged fangs, a distended jaw, scythelike talons, etc. Over time, some Negators can become more akin to the monsters they hunt than their fellow brothers.
