Kid is a slim child mamodo who wears a blue jumpsuit with a K on it. He is partly puppet, which is shown in his various spells which involve weapons and changing the size of his body part. Personality-wise, he is childish and cocky, but also very naive, shown very often when Kid explains something with a lie wich Dr. Riddles had previously made up, and is utterly shocked when Dr. Riddles revealed that it had been a lie.
