|“||This is what happens when there's seven kids and you're stuck in the middle. If my family was a week, I'd be Wednesday... I'm the day people muddle through as the best as they can. Hump day. I'm Hump Day Harley.||”|
Harley Diaz is a main character and the main protagonist of Stuck in the Middle. She is the middle child in the Diaz family of seven kids. She is known for her creativity and inventions.
Harley is portrayed by Jenna Ortega.
Harley is an inventive, caring, and smart girl with a sense of humor. She stands out for her creative inventions. She is an extremely intelligent and observant person as seen as when she invented a roller coaster when Daphne threw Georgie's bobbleheads out the window. Despite being very intelligent, Harley is still social and enjoys spending time with others. She is also very kind as seen when she was willing to help Rachel with her social life and help Georgie with golf.
Harley is strong, confident and is always persistent to get what she wants no matter the cost. As a result, she is a bit pushy and bossy especially when it comes to her inventions and other circumstances. Ethan has called her out for being pushy in multiple occasions. She is manipulative as seen in the way she often manipulates and uses her siblings for her own benefits. She uses Georgie, Lewie and Beast as test subjects in her inventions, some of which turn out to be dangerous. She often uses blackmail and lies to get her siblings including Rachel to do what she wants. She once manipulated Lewie and Beast to make slushies to make her money which resulted in them separating and hating each other. This implies that Harley sometimes doesn't think things through but she is willing to make things right when things go wrong.
Harley also has a temper and can hold a grudge as seen when she was visibly angered when Cuff threw a chicken bone in her invention bag; blasted Rachel with snow when she didn't invite her to a party; held a tight grudge to get Cuff out of the house.
Despite her overconfidence and pride, Harley comes off as the smartest and the most rational of the Diaz kids. She is passionate about her family and will do anything for them. Even when she feels left out and underappreciated, she works hard to keep the family together. She is the one who rallies and leads the other Diaz kids into doing activities that they didn't think they could. Ethan describes her as the glue of the family. And she even wins a special Diaz of the Year Award because of how much she cares about her family.
Harley Diaz is the fourth-born (middle child) of Tom and Suzy Diaz. She is the younger sister of Rachel, Georgie and Ethan. She is the older sister to Lewie, Beast and Daphne. Being the middle kid makes Harley feel unnoticed and underappreciated. She even calls herself Hump Day Harley because she thinks of herself as the Wednesday of the family.
Harley is currently a student at Marshport High School along with her older siblings. When she's not at school, she spends most of her time inventing things, hoping that one day she will make a breakout invention. She hopes that she will get recognized and eventually become the first girl to go to Mars. In Stuck in the Middle, Harley is recognized by her invention of a conveyor-belt table that has a lot of cool features and is also large enough to accommodate a large family like the Diazes.
In Stuck in the Sweet Seat, Harley turns thirteen years old but her family forgets her birthday. She plans to keep them distracted hoping to use it to score some guilt points to convince her parents to give her Rachel's sweet seat. Georgie helps her realize that it's better to celebrate with her family.
As part of family tradition, after turning 13, Harley starts working in her dad's store in Stuck in the Slushinator. She invents a slushy machine powered by Lewie and Beast to prove to her dad that she can do it. Tom is impressed by Harley's work ethic and buys her an actual machine. Since then, Harley has been running the slushy machine section in the special counter called Harley's Slushy Shack. As the owner of the Slushy Shack, she has had to deal with the pressure of hiring and firing people including Cuff in Stuck with My Sister's Boyfriend and Phil in Stuck in a Slushy War.
In Stuck in the Diaz of Our Lives, Harley is cast into a reality show called Girl Power to showcase her inventions. However, after realizing that the producers are more interested in family drama than her inventions, she gets the entire family to quit the show. She eventually gets to appear on another favorite show of hers, "Dancing With My Dad" in Stuck Dancing with My Dad.
To help fund for her inventions and raise money for other things, Harley often runs schemes to raise money. In Stuck with a Guy on the Couch, she secretly rents their living room to an exchange student to make money for a new tablet. She rents their entire house to Colt Bailey in Stuck with a Hook, Line and Sinker. In Stuck without a Ride and in Stuck Dancing with My Dad, she goes to great lengths to convince Rachel to drive her so that she can meet rich people to invest in her inventions. In Stuck in the Harley Car, she starts Harley Care babysitting business to raise money to fix the Slushy Shack. However, she gets carried away and secretly takes over Ethan's Star Tour business so that she can make money by making Ethan take her babysitting charges on tours. Ethan helps her realize that she went too far, trying to make money.
Harley goes to her first school dance in Stuck with a Boy Genius. After being convinced by Rachel and Georgie to invite her internet friend, Josh to be her date to the dance, she does it. Unfortunately, it turns out that Josh is a nine year old. Harley spends most of the night being humiliated and laughed at by other students. When they nominate her and Josh as formal queen and king, she uses the opportunity to show off her invention and put on an amazing dance show.
In Stuck with a Bad Influence, Harley is heartbroken when her best friend, Ellie Peters leaves town for a boarding school. Harley and Ellie would do anything for each other despite the rivalry between the Diazes and Ellie's mom, Bethany Peters. Harley is left without a best friend until a new girl, Sophie Adams joins Marshport High School.
When Rachel leaves the family to go to college in Paris in Stuck with Rachel's Secret, Harley feels responsible to have someone fill in Rachel's shoes. She tries grooming Georgie to be the new Rachel in Stuck with a Diaz Down, but it doesn't work out. She tries taking the Diaz captain role herself but all her pieces of advice end up backfiring. She realizes that no one can replace Rachel. With Rachel out, Harley thinks she's going to have a drama-free life. But then Ellie's cousin, Aidan Peters moves in to live with Bethany next door. In Stuck in Camp Chaos the new neighbors begin a fierce rivalry. To make things worse, Aidan joins Harley's school and attends some of her classes in Stuck with Harley's Bethany. Aidan drives Harley so crazy that Ethan decides to put him in the "Dead to Diaz" list on Harley's behalf.
In Stuck with Horrible Helpers, with the unexpected assistance of her twin brothers, Harley wins the opportunity to compete in the state inventing competition, the Imagination Gladiators. She decides to reward them by letting them join the Slushy Shack staff, but find the Bait N' Bite robbed. In Stuck in a Mysterious Robbery, Harley learns she committed her biggest mistake yet when her dad's Bait & Bite store gets robbed because Harley had left the door unlocked. She is crushed but later realizes that everyone makes mistakes.
Harley has her biggest fight with her BFTF, Ethan in Stuck in a Besties Battle after learning that Ethan went behind her back to hang out with Aidan in Stuck in a Nice Relationship. Despite having put Aidan in the Dead to Diaz list, Ethan had realized how much he and Aidan have in common especially, their shared passion for the same comic books. He had used the opportunity to convince Aidan that Harley is a good person; but in the process he revealed Harley's biggest "Flea-az Diaz" secret. So, when Harley finds out Ethan did, she fights back by embarrassing him in front of Chloe. After the fight, both Harley and Ethan overhear Aidan talking on the phone with his dad. This makes them realize that Aidan is going through a tough time. So, Harley opens up her heart and invites Aidan in to join them for a game night. Harley invites Aidan again in "Stuck with a Non-Diaz" but Aidan ruins her perfectly planned premiere for Ethan's movie. Surprisingly, Aidan saves the day.
In "Stuck Wrestling Feelings," Harley starts to develop feelings for Aidan after spending time together with him and the twins at the wrestling convention. When Georgie points out that Harley and Aidan have a crush on each other, Harley denies it and decides to use science to prove Georgie wrong. Unfortunately, everything adds up to proving that Harley has a crush on Aidan. She tries to suppress her feelings, but Georgie and the twins encourage her to embrace them. So, she asks Aidan out a romantic hang out in the slide.
Harley's relationship with Aidan goes to the next level in "Stuck Without the Perfect Gift" when Aidan gets Harley a very thoughtful gift. Harley gives him a model of the school announcement booth with an audio recording of the time she was yelling at him on live radio. She likes it because it reminds them of how far they've come. But Aidan doesn't like the gift because it reminds him of a moment he would love to forget. So, Harley stages a fake "Who Knows Who Best" game show in order to get to know Aidan better. As Aidan gives his answers, Harley notices that he keeps bringing up his father. So, she concludes that the best gift would be to convince Aidan's dad to come visit him. Aidan had been trying to get his dad to come over but hadn't been successful because he is not good at expressing his feelings. So, he thanks Harley for making it happen.
As Harley approaches fifteen years old, she starts preparing for her quinceañera to celebrate her transition from childhood to womanhood. She wants to have a big science-themed party, using her own chemical element symbol, Hd15 (Harley Diaz). In Stuck in Camp Chaos, she tries to make money for the quinceañera by starting a camp for kids with Ellie. But it turns into chaos when she leads the kids to attack Aidan. In Stuck Without the Perfect Gift, she asks Aidan to escort her to her quinceañera but Aidan turns her down because he has to leave town with his dad. Harley wants the quinceañera to be so perfect that she doesn't even let her best friend, Ellie film it. She goes to such great lengths as doing a terrible fake quinceañera just to push Ellie to quit in Stuck in a Fake Out. This jeopardizes their friendship but they eventually make up.
On the day of Harley's quinceañera, the Diaz family takes over the final action items so that Harley can just relax and have fun. They find Harley's "Buck-Kid List" of things that Harley wanted to do before she became an adult. So, Harley enlists the littles to help her finish the list. Unfortunately, the day goes horribly wrong, with everyone - including Harley herself - messing up. Harley blames herself for ceding control to her family. Luckily, Rachel comes in as a surprise and gets things back on track. Despite many other ups and downs leading up to the quinceañera, it turns out to be better than she imagined. She makes an epic "dancing in the cloud" entrance into the room. She then dances with her family, friends and her surprise guest her boyfriend - Aidan Peters.
After the quinceañera, Harley realizes that her family really cares for her. She says that she used to complain about being the Wednesday of the family, the forgotten kid; but now she admits that being stuck in the middle is not a bad thing. It means you get love and support from both sides.
