Ashlyn Banner is a short girl, standing at 4'11. She has pale skin, freckled most around her face, shoulders, neck, chest, and knees. She has hip-length ginger hair with bangs and sidepieces that frame her face, and she has slate green eyes with prominent eyelashes. Alongside this, she has thin black eyebrows. Her hair is usually in two braids that crown her head, and when her hair's down it's shown to be unruly and wavy. In the phantom dimension, her hair is chin-length and fluffs out in the back. In the middle of Season One, she cuts off her braids, leaving her shadow in the real world braidless, although she still visibally has them in the real world. She's usually wearing clothing with army representation, and she has a black backpack. She can usually be seen wearing ear plugs or headphones due to her Tinnitus and Hyperacusis. In the phantom dimension, she can be seen wearing the black protective suit that was purchased for the group by Aiden. Ashlyn Banner is an introverted girl. She finds socializing exhausting, similar to her mother. She seems to dislike conversating with anyone outside of her family, and it's noted specifically by her father and Taylor that she's never had a friend. She's also quite blunt, as when she's telling Tyler off, she's not seen tip-toeing over her words at all. She loves dance, as she has a DDR (Dance Dance Revolution) mat in her room, and practices ballet. She was taught kickboxing by her parents at a young age, and she only agreed to it due to the fact it could help her in dance. She refused to try when her parents attempted to teach her any other form of self-defense. She is a natural leader, as the moment she and her groupmates ended up in a dangerous situation, she took the reins almost instantly, feeling obligated to take responsibility.
