Hay Lin

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 can be considered a slight comic-alien geek at heart because of her love to collect comics and alien collectables. 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" (in place of more mainstream options like "cool") and "weirdific". 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.

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 comic book, she is the only member of the group who can fly both in and out of her Guardian form, but can temporarily give others the ability to fly. In the TV show, all the Guardians can fly, but still, 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 Nerissa and Phobos Arcs, respectively. She can also create windstorms and tornadoes. 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 soundwaves that travel through the air. When she's excited, she involutary flies up. It should also be noted that Hay Lin has been known to talk to the Air and that it has even responded, in a sense.
