Full Name: Brielle Cook McKatherine.

Nickname(s): Brian (by everyone) and Bri (by Penis and Duck).

Age: 23

D.O.B: March 4th, 1997

Birth Place: China Town, Acmetropolis.

Heritage: Chinese, Acmetropolan.

Species: anthro lioness.

Gender: female.

Sexuality: bisexual.

Relatives: Jason McKatherine (father), Darcy McKatherine (deceased mother), Martha Shepherd-McKatherine (step mother), and Preston "Penis" Shepherd (step brother).

Love Interest: Danger Duck.

Powers/abilities: cryokinesis is the psychic ability to control and create ice and cold temperatures. Brian also took classes in women's defence class, martial arts, karate, and kung fu.

Personality: honest, temperamental, sarcastic and caring, Brian is an (overall) tough girl with a big heart and cool demeanor. She can also be described as blunt, fowl-mouthed, protective of her step brother (and friends and family) and intelligent. If anyone were to hurt (or insult) her, her friends, or her family, she won't hesitate to either beat you into a pulp or freeze you until your whole body is numb (as she has a short temper).

Family relationships:

Jason McKatherine (father) - Ever since Brian's mom died, her and Jason have gotten closer with each other, having the same agreement of not speaking about Darcy (or her death for that matter). A few days after Darcy's death, Bri came out to her dad about being bi, which he greatly accepts about her.

Martha Shepherd-McKatherine (step-mother) - Martha and Brian don't really see eye-to-eye with each other. The reasoning; Brian doesn't like how Martha tries to be her new mom (as Bri thinks she's trying to replace her biological mother). The other reason is simply because Martha doesn't like how Penis is trans, which makes Brian upset for her younger step brother.

Preston "Penis" McKatherine (step brother) - Brian and Penis have a really great sibling bond, as the two share a lot of things in common (for example, their love for dark chocolate).

Fun Facts:

- While Brian gets her chocolate brown hair and royal blue eyes from Darcy, she gets her cream colored fur from Jason.

- Bri used to be in a relationship with Mallory Casey before she turned into Mastermind and got sent to prison. After the incident, Brian requested a visit to Mallory and broke up with her, then left the prison and never visited her again.

- When Tech and Brian met, it started out as him just being her tutorer (in high school), then they started hanging out more and became best friends after a few years. They also share a common interest in science and technology.

- Bri went to the same college as Tech did (Acmetropolis University) before the meteor hit.

- In battle, Brian puts her hair up in a ponytail so it doesn't put some weight on her shoulders (even though she has shoulder-length short hair).

- As a Loonatic member, she wears a black and white suit like the rest of the team, but without the head-piece.

- Sometimes Brian is labeled as "naturally pretty" by Duck, Penis, Lexi and Slam, as the lioness never wears makeup.

- In their relationship, Brian used to call Mastermind "Mal" as a nickname, the name now being dead to the cream colored lioness.

Friend(s): Ace Bunny (big brother figure), Lexi Bunny (sister figure), Danger Duck (current crush), Tech E. Coyote (best friend), Slam Tasmanian (neutral friend), Rev Runner (neutral friend), Zadavia (mother figure/boss), and Mallory "Mastermind" Casey (ex-lover/rival).

Enemies: basically all the villains from Loonatics Unleashed.

Usual Outfit: when there's no crime for the Loonatics, Brian is usually seen wearing a black long-sleeve shirt, a tight mid-thigh jean skirt, black ankle heel boots, a black hat that says "Boy Bye" on it, and silver hoop earings.

Loonatics Unleashed belongs to Warner Bros.
