"All Dead, ha!, if you think every last Arkani is dead it is you who consider yourself above others who shall be extinct. Your people will not live beyond the next millineum." Zenos, to the Urbanoesians.
The Arkani are older than the Plasmoids themselves. They date back beyond the orgin of The omniverse and It was said that Zenos was not the first greatest Evil. If one wished to greatly put right the Omniverse they would have to kill the last of the Arkani.
