Bronwyn is the crossbreed daughter of Kim Kil Whan and Pat, who is first seen in a picture in "Ocarina." She appears again in "Wheels," where she demonstrates her proficiency and interest in skateboarding.
Bronwyn has yellow-orange fur, similar to that of Jake's, with some of it acting as hair that conceals her right eye. She has her mother's bear nose and snout, but her father's eyes and rainicorn horn, which is shown in "Wheels" to be the main source of her teleportation powers, via lightning.
In "Wheels," Bronwyn dresses in a long green dress with a white collar and buttons that reaches down to her knees. The dress has a lightning bolt motif on the front (likely a reference to her lightning powers). She also wears a skull shaped helmet, and white knee and elbow pads. For footwear, Bronwyn wears light green ankle length sneakers with white socks. Her shoes have white straps (one on each shoe) as fasteners.
Bronwyn can be seen as an average teenager, putting up a cool front in the presence of her like-aged friends, while still being easily embarrassed and frustrated by her grandfather and father. Despite this, she does in fact care for both of them and takes her father's advice seriously. She has a definite interest in skateboarding, spending much of her time at home drawing board designs, and skating with her friends at a skate park in the woods.
Bronwyn is an amazingly skilled skater, and she also is shown to have the ability to teleport herself via lightning using her rainicorn horn.
- "Ocarina" (debut)
- In a Twitter post by Steve Wolfhard, the original ending of "Ocarina" would include that child Bronwyn would appear, and her father not mentioning Jake due to Jake's childishness.
