Nascour is a main antagonist from Pokemon Colosseum. He serves as a high ranking admin within the evil syndicate Cipher whose overall goal is to conquer using manufactured shadow pokemon. His past is unknown but given his position within Cipher, he acts rather as its head while the leader of Orre's branch of the organization remains secretive.

Despite his rather sinister appearance Nascour is still human but its assumed he appears that way as influenced maybe by the same thing affecting shadow pokemon. He is a middle aged man with wavy silver hair and red eyes wearing a purple bodysuit and a tattered long reddish skirt.

As a Pokemon trainer he prefers fighting through battle using rather imposing Pokemon such as his shadow Metagross.
