Jester has long deep violet hair that reaches his waist. His face is obscured by a white mask with upturned eyeholes. The left side of his mask has an angular purple reversed heart over the eye, while the right has a small purple astroid under the eye. Additionally, two thin purple lines run down from his smile, giving his mouth a "nutcracker-esque" aesthetic. His mask always depicts a sinister sharp-toothed smile, though it may slightly widen or narrow. Strangely, his mask extends upward, giving the impression of horns. His eyes are bright purple. They are always slits. Jester wears a violet and black jester's cap with four liripipes that have different designs that reach his hips. Three out of four liripipes are violet with black accents, the left most having a row of black astroids running along the inside, while the rightmost has a row of black astroids running along the outside. The second from the right liripipe is violet with a black stripe running along its length, while the second from the left is black with a violet stripe running along its length. All ends are tipped with a bell each. He wears a golden jester collar with a large, black astroid in the centre of the front point. Jester wears a violet garment that resembles the bastard child of a waistcoat, tailcoat, turtleneck shirt, and a princess dress. It has gold and black accents, as well as a golden inner lining. The thing has a golden panel in the centre with black lining on both sides. It was two black stripes running from the armholes near the centre. The back and sides of the garment split into two long, almond-shaped tails. The item is likely worn over a black turtleneck shirt. He has violet puff sleeves with large black astroid on the outsides and golden hems. He wears clawed black opera gloves with golden astroids decoration the outside of his hands, as well as golden streaks that run the length of the inner and outer sides of the gloves. Jester wears loose trousers that are black with two pinstripes running down the centre of the legs, until the mid-thigh, where the pattern changes to purple a with black astroids along the inner leg. He wears golden, astroid-shaped poleyns. He wears knee-high black boots with kitten heels and curved points, reminiscent of poulaines. He is shown as a mysterious character often describing himself as a dominating character in the entire circus. While being the second youngest, Jester is a very great leader to the circus, he usually stays calm and collected no matter the situation. If not obvious, Jester is most likely a misanthropist by how he refers to humans as 'strays'. His taste in music is varied, but he enjoys pop, electronic, rock, and dark synthwave music. Jester implied himself, that he despises if anyone pets him. Jester sleeps on his side or on his back. Jester's special ticket is reserved for the useful and the interesting ones. Jester's current favorite books are "The Art of War" and "O Cobrador." The chaos that would have to be created to impress Jester would involve burning the city down. Jester is usually very gentle. Many visitors return to Jester's tent, so if a frequent visitor went to the circus just to see his show, this wouldn't catch his attention. Jester's preferred position is dominant. Jester's love language is Acts of service. Jester possesses hypnotic/mind-control abilities, activated by looking at the target in the eyes. Jester has a long inhuman purple tongue. Jester gets very possessive once he had decided to make someone his and possibly make them wear a collar and a leash in his color, purple. If Jester likes someone, he would try to make an approach first, then leaving them with a tease then watch them from afar for a VERY long time until he had learnt everything about them, then if the liking escalates, he would somehow sneak into your house and watch you sleep and he would probably kidnap them to the circus once he finally couldn't hold in his liking.
