Properties
Dezrum 569 is a deadly poison to humanoid spiecies and a favourite weapon of many races for eliminating their enemies. When inhaled it quickly attacks the victim's red blood vesells disruptting their abbility to hold and transfer oxygen in the body. The victim is therfore quickly and painfully suffocated from the inside out.

However it was discovered by the 456 that the chemical is only 99.9% affective in the field. The other 0.1% had a diffrent reaction to the chemical wich altered them on the genetic level when they were exposed.

Hours after apparent death the victim would revive with little or memory of who they are with a radically altered personality. They also posessed enhanced strength and agility and regenrative abbilities that nearly rivaled those of Jack Harkness as a result of genetic alteration.

In light of this the 456 were always carfull not to use the chemical on a large area when making threats.
