Nathaniel Kurtzberg

, also called Nathan or Nath, is a student in Miss Bustier's class at Collège Françoise Dupont. In "The Evillustrator", when Chloé mocks his art and his crush on Marinette, he is infected with an akuma by Hawk Moth and becomes the Evillustrator, an artist supervillain whose tablet drawings come to life.

Appearance
Nathanaël is fairly short with turquoise eyes and messy red orange hair. He has long bangs that are brushed to the left side of his face. He wears a red t-shirt with a black design on the front. Over his shirt, he wears a gray dress jacket with folded sleeves and side pockets. He wears purple jeans that are rolled up at the bottom, and his shoes are gray with white lace and a white section where his toes would be.

As the Evillustrator, his skin is light purple, and his hair is brushed back while colored orange with purple tips. On his head he has a black beret, and on his face, he has a black butterfly-shaped mask. He wears a white suit with black stripes and solid black legs that become red halfway down his lower legs. On his chest, there is a black circle with smaller red, yellow, and blue circles inside. His collar is swan-necked, with a red collar underneath. A black drawing tablet is attached to the back of his right forearm. His pen is silver towards the tip, with the end being black with a red stripe in the middle.

Personality
Nathanaël is imaginative and artistic. He is quiet and shy in class, and seems to be quite easily lost in his fantasies, like when he is daydreaming about his crush, Marinette. Afraid of being judged, he prefers to be secretive about his art, and if he is accused of something, he is nervous, and, if the accusations are true, deeply embarrassed.

As the Evillustrator, he becomes more confident and direct, literally walking into Marinette's bedroom to ask her out and celebrate his birthday with him. Even akumatized, he still genuinely cares for her, promising her that he'll stop attacking Chloé and even defying Hawk Moth for a while for the sake of his date. However, he is furious at being humiliated or tricked, and he can be short-tempered and reckless. His response to Marinette betraying him is to yell that she is just like Chloé, and he tries to trap her and Cat Noir on a boat with a huge leak before taking off to continue attacking Chloé.

Marinette Dupain-Cheng
Nathanaël has a secret crush on Marinette, drawing comics in his sketchbook of him saving her from villains. When he becomes the Evillustrator, he has the confidence to act on his feelings, asking Marinette if she would go out on a date with him for his birthday. When Marinette betrays him by leading Cat Noir to him, this hurts him deeply, and he angrily announces she is just like Chloé. It is not explicitly stated, but rather implied by the crossed-out image of his comic featuring Marinette that by the end of the episode, Nathanaël no longer has romantic feelings for her. Nathanaël is relieved to know that Ladybug is around to save the day. After his time as the Evillustrator, in his sketchbook, he has drawn a comic book cover that features Ladybug with hearts drawn in red at the bottom of the page, possibly implying romantic feelings for her.

Chloé Bourgeois
Like most people, Nathanaël dislikes Chloé for being a self absorbed person. He is horrified when she grabs his sketchbook from the floor, seeing his drawing of him and Marinette, and making fun of him for it. He also doesn't like it how Chloé bothers Marinette, so as Evillustrator, he draws a giant hairdryer to blow her away. At first promising Marinette that he wouldn't attack Chloé again, he changes his mind after Marinette breaks his heart and goes to destroy her.

Abilities
Nathanaël is an artist, skilled in drawing pictures with pencil, pen, and marker.

As a villain
As the Evillustrator, he is supernaturally agile and has the power to sketch whatever he wants onto his drawing tablet to make it exist in real life. The objects he creates can levitate and move freely in the air. He can also erase things from real life. However, in order to draw, the Evillustrator needs light, so in darkness he is unable to use his powers.

Trivia

 * Nathanaël's name is an homage to Nathanaël Bronn, the chief art director of the show.
 * In the French dub of the show, the Evillustrator's name is Le Dessinateur, meaning "the illustrator", "the cartoonist", or "the designer."
 * The Evillustrator tries to avoid following Hawk Moth's orders to get the Miraculouses. As punishment, Hawk Moth briefly controls his body and almost prevents him from preparing for his date with Marinette.
 * He is left handed, as when he's the Evillustrator, his drawing pad is on his right arm and he draws with his left hand.
 * However, when he wakes up at the beginning of "The Evillustrator", he is holding a pencil with his right hand, so he may be ambidextrous to some extent.
 * His shirt symbol is based on the French rock band Magma.
 * Nathanaël sits behind Ivan Bruel in class to draw without being noticed.
 * He and Ivan are the only students in the class to not share their desks with other students.
