Marc Anciel

Marc is a fairly tall and slender teenage boy with a somewhat feminine appearance, with messy rock-style black hair with blues reflections, vivid green eyes with visible lashes, thick eyebrows, pink lips, and a slender face with a pointed chin. He also has tan skin.

He wears a V-neck rainbow tie-dye t-shirt which displays the colors in a ripple pattern originating from the center. Over his t-shirt, he wears a bright red jacket with hood and white drawstrings, and pink lining on the inside. He wears moderate azure jeans with the bottoms rolled up and a number of horizontal rips around his knees. He wears a pair of black boots with faint "oil slick" rainbow blotches. He also wears a pair of black leather fingerless gloves, a black leather collar around his neck, and a square-nails belt with a square silver buckle. Hanging from his belt are a pair of square-nails chains that hang around his thighs. His nails are painted black.

Marc is very shy, quiet and nervous around others. This is shown when Marinette pulls Marc into the art room to introduce him to everyone. He is also quite shy in front of his first friend at the school, Marinette, refusing to show her his stories. He likes to write stories (particularly about Ladybug and Nathaniel) but is sheepish and self-conscious when people read them. When he runs away in embarrassment out of the art room, he runs into a pillar and drops his notebook and Marinette picks it up and reads it. When she hands the notebook back to him later on, Marc immediately turns red. Like Marinette, he is sweet and he is very kind but also quite clumsy, especially when he’s around someone he has feelings for.

Marc is an excellent creative story writer. His Ladybug stories, based on Nathaniel's drawings, impress Marinette (the real Ladybug) so much that she pushes him to work with Nathaniel to make the Ladybug/Mighty Illustrator comic. Since the two of them complete the comic, it is implied that Marc's writing skills are strong enough for him to write well in script style as well as in short story style. He is also shown to be quite good at soccer.
