A Toon is a character whose personality (and usually appearance) is greatly exaggerated. Even for the The Comically Serious, comedy colors everything the character does and he is often unable to complete the most basic tasks without falling victim to a number of improbable variables. A probable reason is that many thrive on a consistent, tolerated kind of chaos. The whole idea is often clearly represented by having the characters acknowledge themselves as Toons and Breaking the Fourth Wall.
