Joan Maplewood is a farmer from Dairyville and the mother of Todd Maplewood.
She is a medium-sized person who wears a blue apron and a pink color shirt. She has brown hair, blue eyes and freckles on her face.
Joan is a hard-working person and prefers everyone to be the same. She is very strict and doesn't believe in mummies and other nonsense.
She first appeared in the episode Under Wraps, where she invited Max and his grandchildren to her farm after Max decided to teach them the values of hard-working. She kept giving the children a lot of work to do and was very strict with them. Eventually, the children managed to complete the work by using Ben's Omnitrix to turn into different aliens.
