Death the Kid is known to be a normally calm and mature. Kid also has a great sense of morality and order. However, he believes that everything is about balance instead and strives to keep the balance between "good" and "evil" in equilibrium. Kid also possesses some flaws, most notable him being a perfectionist to the point of having OCD/OD-esque qualities. He is even physically repulsed by asymmetrical arrangements to the point he almost vomited at the sight.
