Delia Ketchum is Ash's mother.
Being strict sometimes, during Pokémon: Indigo League she constantly reminds Ash to change his underwear every day. She is also a good cook and can cook anything. She also helped Brock after Professor Ivy rejected him. She has a Mr. Mime nicknamed Mimey and she has him clean the house for her while she makes breakfast or does the dishes. One of her most famous dishes that is favored by Ash is her "Double deep dish pizza pot pie".
Her most notable appearance is Pokémon 3: The Spell of the Unown, in which she is kidnapped by an Entei to be Molly Hale's mother. It is unknown to who her husband is, though one of the designers of the Pokémon anime say that Ash's father is a trainer on his own journey. Delia went with Ash on a trip to the Unova Region.
