|“||Well, yes, I'm a hypnotist. But, uh, I don't use my skills to get anything.||”|
—Simon, "Simon Says"
Simon Grimault is a hypnotist. In "Simon Says", after Gabriel Agreste gets him disqualified for The Challenge because he doesn't accept the challenge, he is infected with an akuma by Hawk Moth and becomes the supervillain Simon Says.
Simon is tall, having very wavy brown hair and pale grayish-blue eyes.
He wears a high-collared white dress shirt underneath a dark gray vest with black buttons, along with a black bow around the collar. On top, he wears a dress jacket that's lavender with fuscia circles with red swirled lines inside as a pattern, along with a black collar, black cuffs, and coattails. He also wears dark black slacks and black shoes.
As Simon Says
Simon Says is bald, his eyes are dark gray, and his skin is pale periwinkle. He wears a bright green top hat with the bottom of the bill being black and a purple ribbon around the crown. A black mask is over his eyes, and the area close to the eyes is colored indigo. He wears a body suit below the head with a light gray high collar and front, with a large black bow pattern on the front below the collar. The left side of the top of the suit is green with a purple left glove and butterfly sleeve edge, and the right side and bottom of the suit are purple with a green right glove, green butterfly sleeve edge, a green left leg that starts in the middle of the upper leg, and a green right leg that starts below the knee.
Simon is soft-spoken, nice, and nervous. He likes his work, but he doesn't lie about his skills. However, he is upset if he feels wronged, bothered that he is kicked off The Challenge despite it being Gabriel's fault that he failed his task.
As Simon Says, he is outspoken, eccentric, commanding, and overconfident. He thinks fast and uses his cards wisely to get people to do what he wants them to. He is persistent in succeeding to get revenge on Gabriel and get Ladybug and Cat Noir's Miraculouses for Hawk Moth.
As a civilian
Simon is a skilled hypnotist and magician, using cards to hypnotize people.
As Simon Says
Simon Says uses his cards to control people and make them do his bidding. When he draws a card, he says "Simon Says", and then makes a command. A black and white silhouette picture relating to the command appears on the card. For example, when he makes Alec Cataldi act like a duck with one of his cards, an image of a duck appears on the card. Simon Says then throws the card at the person, and it fades into their body, causing the person to do whatever he has commanded them to do. He can give a person more than one command, like making Adrien's bodyguard act like a gorilla with and then making him attack Cat Noir with a second card. He is also able to throw his cards like knives with incredible accuracy. It doesn't matter if the target can't hear him, as long as he gives a command, the person is controlled.
