Duncan Nelson is a crafty 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 considers himself as being "straight with people", rarely pretending to be what he isn't. As a result, he has been shown to either get along with or make fierce enemies. Duncan also loves to make fun of the others, pull several pranks on them and loves to break rules to better suit himself. Mia-bella Lopez is an angel or at least, that's what everyone calls her. Her Dad died by simply being at the wrong place at the wrong time. Her mom died a few weeks after giving birth to her baby sister but Mia-bella helped her the whole way before she pasted. She and her sister were then taken in by her godparents, Mr and Mrs Nelson. Through all this, Mia-bella remained her helpful and caring self. She is well prepared for anything and ready to help anyone in need. So many wonder how someone so sweet, innocent and kind, could be best friends with a delinquent like Duncan.
