Raven was a multi-BAFTA-winning BBC Scotland children's adventure game show that aired on CBBC in the United Kingdom and on BBC Kids in Canada from 2002 to 2010 over the course of ten series, with three spin-off series. It was hosted by James Mackenzie in the title role, who conducts a group of children, known as warriors, over five days through a series of tasks and feats. At various stages in the adventure, the group loses the least successful warrior, until two go through to the final week to compete for the title of Ultimate Warrior.
