Kamen

Kamen was a Po-Matoran. Kamen made sure all of the carvings in Po-Koro would not disintegrate or begin to wear away. After ages of display, erosion has its effect from the harsh winds of the desert. He elaborated once to Hahli: ''I am constantly taking care of the sculptures, so that they do not Disintegrate! Time and weather take their toll on our great works, wearing them down into dust. The enemy of Creation is Disintegration!''

Kamen was among the Matoran that were evacuated to Ga-Koro after Tahnok Swarms threatened to overwhelm Po-Koro. After the Pahrak Swarms cornered the Matoran in Ga-Koro, Kamen made a final stand along with all the other Matoran present, before the Bahrag were defeated by the Toa Mata. He later departed back to Po-Koro.

Kamen helped to build Boats to facilitate his and the other Matoran's return to Metru Nui, where he now resides. Kámen means "stone" in Czech and Slovenian language.
