Jevil is a short, pudgy imp with a round gray face, elven ears, clown-like eyes with small yellow pupils and black sclerae, and a large smiling mouth with yellow, sharp teeth. He has a long, purple tongue which can be seen either when he laughs, or during some of his attacks. He has a purple tail shaped like a capital letter J. He is dressed in a purple shirt, black trousers, a black cape, green slippers, black socks, purple mittens, and a lime green and yellow jester's collar. He wears a purple and black harlequin jester hat with two small yellow bells. His head appears to be connected to his body via a coil spring (akin to that found in a jack-in-the-box), which is only exposed when attacked.

Personality

Jevil is described as mad since he met a "strange someone..." Prior to losing his mind, he was a jester with a presumed jokey attitude and a friend of Seam.

Now insane, Jevil is still portrayed as an eccentric individual. His dialogue is rife with maniacal laughter, repeated words, rambling puns, and strange sentences, and he has a sadistic sense of entertainment, considering battle with the party to be a "GAME." He has a very cynical view of the world around him and considers everyone around him to be trapped while he is the only one truly free, despite ironically being jailed from the world. Seam however finds some sense in the words of Jevil, indicating that his insanity might be a form of awareness.

Jevil, like other Card Kingdom denizens, is implied to be a playing card. Specifically
