The Gen'Dai were a seemingly immortal species with distributed nervous and vascular systems. Lacking the vulnerable vital organs of most races, including brains, hearts, and lungs, Gen'Dai could take extreme injuries and even complete dismemberment, and survive. However, if a Gen'Dai took too many injuries, they underwent an extended period of hibernation, during which they could regenerate. However, they could be permanently killed when vaporized or completely destroyed.
