Delia Ketchum

Delia Ketchum is Ash's mother, and a very good friend to Sam Oak.

Delia once dated Giovanni, from whom she got pregnant. Sam Oak, having met Ash during his childhood, helped Delia get away from team rocket, knowing how great of a person she would bring into this world. Eventually, Delia moved to Pallet and raised her son there.

Before the start of this story, Delia was delighted with Ash's and Misty's relationship. When their relationship fell apart, Delia had a fight with Ash and Ash left after having a fight with her and everyone else, on a quest to rid the world of the darkness and bring back the time sof innocence.

Delia keeps in touch with Misty until she gets paralyzed, in which case it is difficult for her to travel often.

When Articuno attacks Pallet, Delia is seriously injured but survives, and as a result she cannot walk anymore. She is saved due to being aided by team rocket, due to Giovanni actually being a past relationship and Ash's father. While treated, Delia is recruited to the dark side and accepts the darkness within her, same as Giovanni.

Over time, she manages to recruit Ash in the dark side as well, ensuring him that accepting the darkness is the way to return to the age of innocence, and that there are no negative emotions for someone who has given in.

After that, during the second attack on Pallet, she is captured by Team Cipher. Cipher don't know that she has aligned with the darkness, but use her as hostage to force Sam Oak to work for them. She is rescued and continues living close to Sam Oak, and reunites with Ash and her grandson Vergil.

Before the battle fo Saffron, she tries to recruit Sam Oak to the darkness too, but he doesn't give in and she poisons and kills him.

After it, she is brought to the new Capital by Ash, and serves as an ambassador for people who wish to accept the darkness. She continues to live there until the end of the story, where she is returned to normal after the sealing of the pokemon world from the multiverse.
