antidermis

Antidermis was the name which the Piraka gave to the green-black virus they used to enslave the Matoran of Voya Nui. In fact, this "virus" was actually the life essence of Makuta Teridax. Axonn shattered the Piraka's antidermis vat, forcing Makuta to find another host body or risk being permanently dispersed into the atmosphere.1

Notes

The Piraka's zamor spheres contained the antidermis virus, which could enslave others.2
