Karen

Karen (Karen Katphish) from the web series SMG4 is an anthropomorphic cat who works as a shop assistant and cashier at various establishments in the Mushroom Kingdom and is also a single mother of three. Her coat and hair: She has white fur and white hair with turquoise streaks underneath and inside her ears.
Tail: Long, fluffy tail (white with a turquoise tint), decorated with a red bow.
​Clothing: Karen's casual outfit consists of a light green t-shirt, tight black leggings, and black boots.
Additional Notes: Due to her unique design, she sometimes attracts fans' attention with her style, reminiscent of classic animation or game characters. Karen from SMG4's personality, character, and communication style make her one of the show's most recognizable and hilarious supporting characters. Her design is built on the contrast between her cute cat appearance and her harsh, stressed-out life as an adult. In the current SMG4 universe, Karen doesn't have a fixed job title—her workplace changes depending on the needs of the story. She works a variety of low-paying service and retail jobs throughout the Mushroom Kingdom. Salesperson, Cashier, and Barista: She has worked as a barista at a local Starbucks, a cashier at supermarkets (such as Walmart and 7/11), and an employee at fast food restaurants (including McDonald's).
Service Worker: She can also be seen working as a laundrywoman (lined-aid), airport cleaner, landfill worker, and other similar jobs. Her main "job" in life is as a single mother of three, for whom she must take on any part-time job to provide for them, while fending off the crazy antics of Mario and other characters with her trusty shotgun. She has left her past as a professional hitman behind.

Constant fatigue and burnout: Karen is a classic example of a service industry worker, dead tired of her job, her clients, and her routine. She views the madness of the Mushroom Kingdom around her not with surprise, but with a deep existential stoicism.
Single mother: She has three boisterous kittens, whom she raises alone. This has left its mark on her character: she is incredibly practical, somewhat tough, and used to dealing with any difficulties on her own.
Indifference to Chaos: While the protagonists of SMG4 constantly cause explosions, destruction, and disasters, Karen maintains an Olympian calm. If an apocalypse were to unfold right in front of her counter, she'd likely simply roll her eyes and continue scanning her merchandise (or demand that store property not be damaged).
Hidden Toughness: Beneath the guise of a harried cashier lies a person with nerves of steel. When necessary, she can stand up to troublemakers or solve a problem in the most radical and pragmatic way. Dry, cynical, and sarcastic humor: Karen almost never shouts unnecessarily or displays strong emotions (except irritation). Her remarks are full of dry sarcasm and caustic remarks directed at customers or the absurdity of the situation.
Deadpan Delivery: She speaks in a monotone, tired voice, no matter how strange or dangerous the situation around her is.
Directness: Karen doesn't waste time on polite bows. If someone is being stupid or holding up a line, she'll point it out directly and without censorship.
Ultimately, Karen is the perfect embodiment of the "tired worker" who is stuck in the middle of a crazy cartoon world and just wants everyone to finally stop ruining her work shift.

Karen's past and personal life are full of unexpected twists and turns that reveal a completely different side of her—from a tired cashier, she turns into a character with a dramatic background.
Past and previous work
A difficult childhood: Karen grew up on the streets as a stray cat (presumably abandoned by her parents). Because of this, she had to learn to survive on her own early on.
Professional Hitman: In her youth, under the name Katana, she worked as an assassin for the shadowy organization "Hitman, Incorporated." She has dangerous missions under her belt, combat experience, and excellent firearms skills (which explains her incredible hidden strength and composure in emergency situations).
New life: Over time, she became disillusioned with her criminal past, left the organization, and decided to live a quiet civilian life, raising children.
Ex-husband
Karen's ex-husband is Mr. WPNZ (they previously worked together as assassin partners in "Hitman, Incorporated"). He's incredibly chaotic, reckless, views children as tools for survival, and strives to train them into ruthless fighters. Why did they split?
​Different views on life and family: Their romantic relationship and work together began in dangerous circumstances, but after the birth of their children, Karen longed for a quiet, safe, and stable family environment. Her husband, however, remained committed to a criminal and dangerous lifestyle.
Disappearance: When the children were young, he effectively disappeared from their lives, leaving Karen to cope with motherhood alone.
Conflict and divorce: Years later, he resurfaced. A bitter conflict erupted between them over parenting methods: Karen advocated for the care and safety of the children, while he tried to drag them into dangerous adventures. After Karen finally stood up to him and defended the family, she ended their relationship by officially announcing their divorce.
