Douglas was born to Walter McNoggin and his wife in the year X14. It is unknown whether he and his family lived on their homeworld of Cerebellia or Intrepidville when Douglas was born. In the year X21 Douglas met his three closest friends Eddie, Lloyd and Kurt; the latter of whom would become his best friend for years to come. He was one of the only three kids who did not laugh at Lloyd when he made a fool of himself on his first day.
Douglas is an intelligent and intellectual boy, possessing knowledge so vast that it leaves his friends baffled most of the time. However, because of his love for science he has been labelled a "dork" and a "nerd" by many of the kids at Luna Vista. Douglas is in some ways Kurt's polar opposite: while Kurt is big, strong and quite dim; Douglas is small, scrawny and sharp-tounged. Douglas seems to be the voice of reason for the group as he believes that he and his friends should keep their noses out of trouble. Of course it doesn't take much from Eddie to convince him to join in on their schemes.
