Like Jake, Haley also has dragon powers, although hers are not fully developed yet despite the fact they start developing in an earlier age than Jake's (In "Legend of the Dragon Tooth", Their mother explains that dragon girls develop their powers earlier). She takes pride in exposing Jake's mischievous behavior to their parents, as well as showing off her own "superior" talents. Normally the audience only sees little parts of her dragon form, such as her wings and tail. In "Family Business", her full dragon form is revealed, and she begins her own dragon training under Sun Park's guidance. She has taken many aspects of her training with Sun to be applied in her daily life, which puts her at odds when paired with more "average" kids her age. She also seems to take pleasure in making her brother look bad as a dragon. However, she is starting to show more respect towards Jake. In fact in the episode "Family business" Haley openly admits that Jake is a better dragon than her, and in the episode "Being human" where she take's Jake's place as the American dragon she quickly suffers a breakdown and realizes how hard it is for her brother to balance his human life with his magical duty. It is revealed in "Haley Gone Wild" that she has never gotten in trouble (until the end of the episode) and she says doing something bad is against her nature. She is present in "Homecoming", when Rose betrays her brother before destroying the Huntsclan. She witnessed Jake trying to save her before he destroyed all of the skulls in a furious rage. She also takes part in the final battle with The Dark Dragon rescuing her grandfather, re-capturing Councilor Chang and witnessing Rose's return to help as well as the Dark Dragon being trapped for a thousand years in another dimension. She later cheers for Jake and Rose and returns back to the hotel with her family.
She was named after Haley's Comet because her mother said that she loved the name "Haley" while still dating Jonathan.
Concept sketches show that Haley was originally going to be named Brittany
She somehow knows who Chang is in Season 2 despite not meeting Chang in Season 1.
Not a surprise, she was being trained by Sun Park to be the Substitute American Dragon, so surely her studies explained who Former Councilor Chang was.
In Season 1, Hayley is suggested to be a purple dragon, as she transforms certain parts of her body, which were purple and draconian, but never entirely became a dragon. In Season 2 her full body form was shown to be a pink dragon.
It is unknown if Hayley could fully transform early on. It may have been she was not physically mature enough, or her mother and or grandfather told her not to do so at the house. The latter is supported by Mrs. Long scolding her for changing her hands to claws to chop vegetables.
In the episode "Legend of the Dragon Tooth" Haley changes completely for the first and last time during Season 1. This time we see that she has a long dragon neck, lighter purple underbelly and darker purple spikes on her back as Jake has.
In reality, Haley was named after Eminem's daughter Hailie
