Doreen is very caring, especially as a mother. She worries about Lucas constantly and babies him, much to his dismay. She is very sensitive and loves her family very much. She also seems to be the only member of the nickle family to have sympathy for the ants as she tells lucas to come inside upon seeing him attack the hill and nearly squish zoc and hova she also did not appear to know her husband had contacted a exterminator to gas their yard
Doreen is a pretty, middle-aged woman. She is pear-shaped with a large butt. She has light reddish hair and dresses the way an older mother would.
