Zobae Disease

The Zobae Disease also called "The Immortal Sickness", is a mysterious disease and one of the Five Great Calamities that humanity met in the Dark Continent.

Background
When the kingdom of Kukanyu did an expedition to the Dark Continent searching for the achemical plant known as "Metallion" with the help of a group of hunter guided by Beyond Netero they succeeded in retriving it but on their way back they lost their way, took the wrong route and some of them ended up contracting the tremendous Zombae Disease. Of the entire expedition team, Hunters included, only Beyond and other 5 survived along with a Hunter infected by the disease, and as if that was not enough at the end of the expedition the plant whithered and died.

Effect
Not much is known about the Zobae Disease, but it allowed an infected Hunter to survive entirely self-sufficently and without sustinence as a human does for many years, making the host practically immune to death. According to Ging Freecss the level threat of the Zobae Diseae is B+, like that of the other Five Great Calamities, this is even greater of that of the Chimera Ants.
