Zia Eliza Simpson-Van Houten is the future daughter
|Hair||Blonde, blue single lock|
|Relatives||Father: Milhouse Van Houten|
Mother: Lisa Simpson
Zia looks near identical to her mother, Lisa, due to apparently only having her genes. Zia's hair is similar to Lisa's, except it is rounded instead of pointed, and she has a longer lock of blue hair, which may have come from Milhouse's genes, although due to apparently not having any of his genetic material it could have been inherited from her maternal grandmother, Marge, or she dyed it. She has a changing tattoo on her left arm, one of which is the Taoist symbol the Yin Yang, a peace sign, and a biohazard sign.
She wears a purple crop top, a magenta skirt with a dark grey belt and purple straps on the side, dark magenta boots with magenta soles and straps , and a magenta bracelet on her left arm.
Personality and traits
Zia spends much of her time plugged into the Ultranet, and in doing so somewhat annoys and worries her mother. When she is not plugged in, she is shown to be sarcastic and arrogant around Lisa, shooting down her mother's attempt to connect with her. Her rebellious nature leads Lisa to think that Zia doesn't respect her, stating that Zia thinks she's a "ruthless tyrant", and questioning how her daughter turned her brother, where ironically she acted no different as a child towards Marge, her own mother. Lisa brings Zia with her to her parent's home for Christmas while Milhouse nurses his seasonal allergies, but Zia plugs herself into the internet for almost the entire time.
Worried, Lisa enters the Ultranet to check up on Zia despite her own feelings and Marge's advice.
Lisa finds Zia's Ultranet Room to be filled with things dealing with science and other studies, and there are posters in her wall of women such as Joan of Arc, Marie Curie, and Lisa herself.
Zia appears and then questions what Lisa is doing there, Lisa tells Zia that she's sorry for invading her privacy, and that she only did it out of concern, but she's glad because she learned that her daughter looks up to her. Zia replies that she looks up to both of her parents, but she especially looks up to her mother, and they both hug. As they do this, a door to another room, a dance club, opens slightly behind them. Zia closes the door before her mom notices.
Zia appears with the rest of her family at the end of the episode, at the Simpson's house on Christmas Day. After Maggie arrives home with her baby girl, Zia and everyone else gather around for a Christmas photo.
- Zia's last name is highly disputable. It is implied that Milhouse took Lisa's surname, as their Christmas card reads Simpson-Van Houten-Simpsons-Simpsons, and due to Lisa's nature she likely would have wanted to keep her last name. However, Zia's Ultranet Room reads on the front "Zia Simpson". One reason could be because Zia has a better relationship with her mother (Lisa Simpson) than her father (Milhouse Van Houten). In The Simpsons: Tapped Out, her name is listed as “Zia Simpson”.
- Zia has a tattoo on her upper left arm that is evidently a hologram or some other similar device, since it changes into several different designs. These designs include:
- A plain circle.
- A peace symbol.
- A biohazard symbol.
- A yin and yang symbol.
- Abraham Simpson I is a presumed great-great-great-grandfather of Lisa, Bart and Maggie and a great-great-great-great-great-granduncle of Milhouse. Milhouse and Simpson kids are distantly related through Abraham and Eliza's mother Mabel so it will make them distant cousins. This fact means that Abraham will be both 6x granduncle and great-great-great-great-grandfather to Zia.
