Name given by the PIRAKA to the green-black virus they used to enslave the MATORAN of VOYA NUI. In fact, the “virus” was actually the life essence of the MAKUTA of METRU NUI. The vat containing the antidermis was shattered by AXONN, forcing Makuta to search for another vessel to house his energy or risk being permanently dispersed into the atmosphere.
