Delia is the mother of Ash Ketchum and she resides in Pallet town with a Mr. Mime she befriended. It is unknown who fathered her child Ash as she lives at her home without any other humans and there has been no indication that she has been married to anyone. Delia seems to work at home doing gardening, house work and cooking. She is also very good at sewing and making clothes as she makes her sons clothing.
She is always happy to hear from her son as he travels to become a Pokémon Master. She always reminds him to be good and to change his underwear. She is always striving to be the best mother that she can be.
Her good friend Professor Oak lives nearby and she often visits him to drop off cooking and to be a bit of company for him. Their relationship seems to be a bit more than friends as they have gone on a few trips together: to Aopulco and also to the Isshu region where they dropped off Ash together.
