The Kratt Brothers

Gourmet has a massive upper body, large, hairy arms, a small English mustache, grayish-green eyes, thick black eyebrows, a shaved head, and an abnormally large, bulbous nose with prominent nostrils. He typically wears a white chef's hat, a white apron, a dishcloth on his belt, hiking pants, and black boots. In the episode "Tropical Fruit Stew," he is also shown wearing red and white striped underwear. He often carries a quiver containing some kitchen utensils. When it's cold outside, he wears a parka, a knit hat, and mittens, but keeps the dishcloth, hiking pants, and black boots. Gourmet is always confident that he will succeed, despite the constant interference of the Wild Kratts. He's clever and cunning, and has managed to outsmart the Wild Kratts on more than one occasion. He often sets up the Kratt brothers, putting them in mortal danger. Paisley is a petite, slender woman of very short stature with a pear-shaped figure, short, chin-length platinum hair, pale, grayish skin, and light green eyes. As a businesswoman, she wears a gray long-sleeved suit and a dark gray knee-length pencil shirt, along with a skirt and black heels. She also wears square, black glasses. Paisley is quite picky, but also very prim and proper. She despises nature, calling it disgusting, panics over such trivial things as stepping on the ground, and generally doesn't care about wildlife. Rex (Paisley's assistant) is a middle-aged man, one of the tallest (he's one of the tallest villains, possibly as tall as Dabio or Donita), but also slightly overweight. He has dark skin, short brown hair cut in a buzz cut, and brown eyes. He wears a gray long-sleeved shirt, a black belt, blue jeans, and brown shoes. This is his uniform: a yellow helmet, an orange vest, and yellow gloves. Unlike other villains, Rex is very energetic, passionate, and hot-tempered.

She usually wears dark purple pointy-toe high-heeled shoes and wears black eyeshadow, black eyeliner, and light brown lipstick. Donita gets angry and loses her temper easily. She is disrespectful to people, especially her henchman, Dabio, to whom she is constantly rude. Although she can handle work herself, she often doesn't do so because she believes it will make her look "unfashionable." Dabio (Donita Donata's assistant) - He has a broad upper body and a slender lower body. He is very muscular, as evidenced by his large arms. He has blond hair. He wears a turquoise T-shirt with a symbol in the middle and white pants. Between the T-shirt and pants is a brown belt. He wears a brown bandage on his right arm and gray dress shoes.
