Cartoon Marty!

Age and Gender: He's a teenage boy. Hair: Reddish, rather tousled—this adds a lively and informal touch. Clothing: He usually wears a green shirt and black pants with black overcoats, and a small red cap on top of his head. While the details may vary slightly from episode to episode, this basic set is his signature look. General Features: He has large, expressive eyes and a rather wide smile. Overall, the character's design is quite simple yet dynamic: these traits are perfectly representative of Nickelodeon's style from the 2010s. In the story, Marty is the mascot of the Toonmart store and the life of the party in the fictional town of Toonville. His energy and sociability are perfectly reflected in his open, lively appearance.

Holly is a blue robot. She has metal arms and legs, and red antennae protruding from the sides of her head. She's quite tall and smart, and she's never one to pick an argument without reason. Incidentally, the character was named after her voice actress, Holly Gauthier-Frankel. In the series, Holly is one of Marty's friends (along with Bernie).

Jack is an anthropomorphic mole. His fur is an unusual shade of reddish-brown-purple. He wears dark green overalls, a yellow shirt, and round glasses. In the story, he is the owner of the ToonMart and Marty's boss.

He's a plump guy with apricot-colored skin. He has red hair that sticks out to the left. He also has freckles on his face. As for clothing, Bernie wears a red shirt with a flame design; red pants and shoes; a blue cape; yellow gloves; and a belt. He's a good friend of Marty's, although he can get angry with him in some episodes. He can fly and control fire. Incidentally, Bernie is the son of the villain Bernatron.
