Most Royal Guard Dragons have what RGDS researchers describe as leather like skin.
Although Royal Guard Dragons are warm-blooded, their skin has no pores or sweat glands.
Studies performed with the Royal Guard Dragons’ permission have shown their skin to be impervious to any known chemical or mechanical assault including attempts to breach it using high-powered lasers.
In addition, Royal Guard Dragon skin appears to provide the dragons complete shielding from all known forms of radiation.
