Dezalk

Dezalk was a Ta-Matoran living on the Southern Continent. After the floating island later known as Voya Nui rocketed up to the surface, Dezalk the other Matoran struggled to stay alive. When the Piraka posing as Toa invaded, he was the first Matoran to be infected by the Piraka's Antidermis. Zaktan then ordered him to round up the other Voya Nui Matoran so the Piraka could infect them all with Antidermis as well. After the Piraka were defeated by the Toa Inika, Dezalk was freed from the Antidermis, and is currently back on the Mainland, as Voya Nui has returned to it.

Trivia
Dezalk is the only other Voya Nui Matoran whose name is known besides the Matoran Resistance group.
