Reverser

Reverser (voiced by Kyle McCarley) is an inverting supervillain. Reverser is in a checkerboard patterned outfit. The left side of the outfit has solid black markings, like on the upper head, arm, fingers, chest, torso, and leg. On the right side, the lower head, palm, teeth and half of a circle on the chest are black. Reverser's weapon is a white and black paper plane that can reverse the abilities or the personality of the person who is hit. He rides on a triangular paper plane-like hover board. As Reverser, Marc is demanding and clever: realizing that Ladybug's graceful agility made her difficult to strike, he endangered civilians in order to make Ladybug an easy target when she went to help the affected cyclist. He is also confident, leaning on a bit overconfident: after he struck Ladybug and Cat Noir with his arrows, he saw them as no threat and believed he had time to obtain his revenge on Nathaniel and Marinette before dealing with them.

Powers and Abilities
Reverser rides on a large paper airplane, which has the ability to fly around at will. He can also make small black and white paper airplane "arrows" with the ability to change a personality trait to its opposite, by calling out what trait he wishes to reverse. Primary examples are when he made Ladybug become extremely clumsy after hitting her with a paper plane, or when he made Cat Noir a coward. This can also affect specific actions, as Reverser was able to make André Bourgeois bring the trash containers in space back to Earth.
