Personality
She can be very shy and nervous. When she has to she is brave, heroic, and will never try, but do to save the day. Even though she is shy, that doesn't mean she doesn't know how to put bad guys in their place.

Karen is always a skilled mathematician and also a computer programmer. She also reacts quite rashly when someone damages her things but is quite friendly. She likes to think quick and solve problems, using her own interests to her advantage. She is helpful, she wants to help the world improve, and likes to work, even when overworking herself at times, she doesn't like getting pulled away from it. She tries to focus and not being clumsy or goof off.

Physical Appearance
Karen is a bit half Mexican (by her father's side) and half Chinese (by her mother's side) slender female, although she more closely resembles a African-American and has hip-length black/dark brown Afro-like hair with bangs (which her bangs references to Luna Loud) that she normally ties into low bun-like pigtails, brown skin and brown eyes.

When she was young, it was shown that she had two circular blue-framed glasses with same color scheme, which are somewhat more oval-shaped and less thick, short hair into a chin-length with purple ribbon in it, and red hoop earrings.

Clothing
Karen is always (except as the Yellow Ninja which allow her to fly as a canary) seen wearing a long-sleeved orange sweater-like jacket underneath a very soft orange sleeveless dress, light black cat-eye glasses with lighter shade lenses that are a translucent blue color (and only her pupils with eyelashes can be seen through them when she is wearing them), black jeans, orange hoop earrings, white circle-like necklace with pale yellow line, and red shoes that are similarly flats. She also wears three black bracelets on each of her wrists.

For nightwear, she wears a short-sleeved light yellow shirt with white sleeve ends and a bumblebee symbol and long-legged light yellow pants. She took her glasses off while she sleeps and also lets her hair down, showing her hair to be hip-length.

When she was young, She wore a pale yellow short-sleeved dress with a single, horizontal, white stripe going down the middle, white socks, and short, red boots.

Quotes

 * Karen: Harley Quinn wants to blow it up so she doesn't have to take a test, which is crazy because why didn't she just study? And Catwoman lost a coin toss, so she's there, too. And so is Giganta, and Livewire, and Star Sapphire, and Poison Ivy. And if they succeed, traffic is going to be nuts, and that's no good for anybody. And I have to cross that bridge to get to piano lessons. And, like, I want to spend that much time in a car listening to my dad talk about the '90s? (Bridge of Doomsday)
