XXV was born on a distant planet into an alien society as the child of a Birth Queen and an unknown drone. When examined for his skill set he was found to have reasonable intelligence, above average physical capabilities and a high level of disregard for other life forms. Taking this into consideration, the commanders placed him in the 'harvester' division, a job which involves collecting mammalian samples for scientific analysis, with a Sim being the most highly prized catch.
XXV and his ship were stationed to watch over a largely uninhabited area of SimNation, something which he privately resents a great deal, as until the arrival of Cherry Rose he had very little to do.
