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.
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.

- In a Twitter post by Steve Wolfhard, Bronwyn's parents tried to keep Jake a secret from her due to his immature behavior.
