Duncan is the definition of a bad boy, being a crafty, cool juvenile delinquent who comes from a long line of policemen and policewomen. His dad, mom, uncle, aunt, grandma and cousins are all cops. He knows many tactics from his time spent in juvenile detention centers. He can carve a picture of a skull into a tree trunk and lift great amounts of weight (such as Owen, who is more than three times his size). And He has a brooding, obnoxious, sarcastic and flirtatious personality.
