You, my little Hay Lin, will be free and light as the air!
Hay Lin was born on June 4th and was raised in the town of Heatherfield. She is feisty, confident, protective, full of energy, and very optimistic and determined.
She is one of the five teenage girls who are chosen to be the new Guardians of Kandrakar. Their mission is to protect Kandrakar; the center of the universe and the other planets from evil.
Hay Lin's family is of Chinese origin. She has long blue-black hair which she usually wears in two pigtails and brown eyes. She often wears bright-colored clothes. Partway through the series, she begins to wear dental braces, which she later had removed.
While Taranee's uniform is more fit for mobility (as are most of the Guardian's except for Cornelia's which is very elegant), Hay Lin's seems to put emphasis on grace and freedom. However, it is also the most revealing. It consists of a small, teal, cropped top whose sleeves curls around her shoulders, and a purple, knee-length skirt with slits at the sides, revealing most of her legs. A beaded cord is tied around the waistband, similar to how she decorates her civilian outfits with shoelaces. She sports purple Mary Janes as well as turquoise and green-striped tights.
In the New Power Arc, her uniform seems to be loosely based on a cheongsam. Her top appears to be the upper half of a cheongsam mixed with a halter top. Her skirt has grown long and wispy, and the beaded cords are gone. Instead, they are replaced with matching purple bands that hug her rib area. She also has more bands around her arms, except these are teal-colored, and she wears black, fingerless gloves. Her hair has grown longer and parts of it are styled into traditional Chinese buns.
Hay Lin is something of a free spirit: she's absent-minded, but at the same time extremely creative, talented and insightful when it comes to people around her. She loves to draw, paint, and sketch. It is no surprise that her favorite subject in school is art. She has a sense of humor rivaling that of Irma's. She is a slight comic-alien geek because of her love to collect comics and alien collectibles. She enjoys just about anything related to science fiction, air, or art. Her quirky style spills into dialect as well, with idiosyncratic expressions like "cosmic", "spacious" and "weirdific"(in place of more mainstream options like: "cool"). In the Spanish version of the comic, she often exclaimed: "Yap!" Hay Lin is not superb at Physical Education, as shown when she herself once says she shall need to get into shape after running.
Her family owns a Chinese restaurant called The Silver Dragon where she often works at to help her family out. She has a habit of writing people's names, dates, numbers, and anything else that might come in handy on the back of her hand, or arm so she does not forget anything important during one of her creative brainstorms. She has a huge crush on the new boy in town, Eric Lyndon, who likes her just as much. Hay Lin had her first kiss with Eric.
Hay Lin works at her family's restaurant and goes to school at Sheffield Institute. She would often goof around in her classes. Once, she was assigned the task of making a simple kite for a school project. She decided to make an overly fancy Chinese dragon kite and spent all night working on it. Her teacher failed her before Hay Lin even had a chance to fly it because her teacher assumed it would not fly on its own and that it was far too heavy to even lift off the ground.
Powers and abilities
- Main article: Hay Lin/Power development (TV series)
Hay Lin has the power over air and can manipulate and control various aspects of said element, including wind and clouds, she can even turn her breath into a weapon for both versions. Hay Lin can move objects using her elemental power, and in the comics, she is the only member of the group who can fly until Arc 7: New Power, both in and out of her Guardian form, but can temporarily give others the ability to fly. In the TV series, Hay Lin is the one who can fly the highest and quickest among them. She can conjure clouds and even use her power to soundproof rooms, as she did in the Arc 2: Nerissa's Revenge and Arc 1: The Twelve Portals, respectively. Hay Lin has shown an ability to control the temperature of the air, and often uses this power to freeze enemies. She can also create air bubbles for traveling underwater and can hear things on the wind because of the sound waves that travel through the air.
Advanced elemental abilities
Hay Lin can recall a person's memories by listening to their favorite music and creating sonograms with the sound to show them the images of their past, and also learn the history of an object by the sound it makes. When she does this, she is feeling the atmospheres the object was in and how it was touched. In the TV series, Hay Lin is the only one who can become invisible and make other things invisible. In the comics, all the girls can become invisible. At some point, Hay Lin has managed to do shape shifting. Also in the TV series, she was capable of Empathic Precognition; if she's thinking strongly of someone before she sleeps, she can see what will happen to them in the future, like she did with Elyon before her coronation.
When she becomes one with the air dragons in "Z Is For Zenith", she becomes an air-like being with her pigtails swirling around her like a cyclone.

The Star of Threbe: Hay Lin as well as the rest of the Guardians was rendered powerless due to the power of the Star of Threbe, used to find Elyon. The star renders powerless anyone who might prevent her from returning home. Ironically the star was created with the Heart of Kandrakar.
Hay Lin experienced her first love when Eric Lyndon comes to town, though their initial meeting differs between the TV series and the comics. In the TV series, she saw him out on the street and became enchanted with him at first sight. As Eric was immediately popular in school, Hay Lin hesitated to approach him and doubted that she had a chance to catch his attention even as he showed a great interest in her. This changed when he was endangered by Nerissa and Hay Lin finally conquered her fears by kissing him, starting the relationship.
In the comics, the two met during a near collision between his motorbike and her roller-skating, though neither was hurt. He came to visit her at The Silver Dragon and they continued to grow closer to one another.
Their time together was cut short when Eric moved to Open Hill with his parents and though the separation was hard for Hay Lin, they continued on a long-distance relationship, but Eric began to fade into the background of Hay Lin's life. Eventually, he stoppws appearing all together and Hay Lin moved on to a new crush implying the two have grown apart completely. In the New Power arc, Eric is given a passing mention but later, Hay Lin is said to have not yet fallen in love, effectively writing Eric out of her past.
In the Teach 2b W.I.T.C.H. arc, Hay Lin became acquainted with Liam who secretly stayed in her home. Hay Lin admitted to her grandmother that the boy is handsome and she was the most upset when Liam betrayed them, going so far as to slap him when he turned to her for help.
Hay Lin fell for rising rockstar Vincent Cohen, changing herself to fit the image of the girl he actually likes, Airin. This caused strain with her friends and her mother as Hay Lin threw away her previous interests and neglected her other responsibilities while in pursuit of Vincent's affections. Eventually, after sneaking out to his birthday party, she watched him and Airin kiss and was forced to accept that he doesn't love her. She continued to be friends with them both and later, seems to have caught the eye of another boy while studying in the library.
Hay Lin began a new long-term relationship with flute player Wesley Hampstead. Their relationship progressed smoothly and after a small time apart while Wesley left to tour with his uncle's orchestra, he returned and the two became an official couple.
