His tendency to think negatively is what made him an easier target for t he Beast to drag down into despair. In chapter eight, Babes in the Wood, Wirt finally begins to succumb to his hopelessness and gives up on the notion that he and his brother will ever escape the Unknown. Throughout the storyline of Over the Garden Wall, Wirt has to struggle to remain optimistic against impossible odds. He is easily scared and surprised, and even though he is far more perceptive than his brother, he is very much still a kid. Wirt is a pessimistic realist in many ways, but also has a naïve and childish side to him. Without his hat on, Wirt's hair takes on a rather messy appearance. His normal attire consists of an earth-toned sweater that he wears over a collared white shirt and ordinary gray slacks, possibly the same pants that he wore with his costume.
In the episode Into the Unknown, it is revealed that Wirt's outfit is merely a Halloween costume. They are commonly left untied, a noticeable trait throughout the series. He wears two different types of shoes, his left shoe being dark gray/brown and the other being black. He has large ears, a pointy nose and and big, round eyes with black pupils.
His hair is dark brown with pointed bangs that cover the majority of his forehead. His outfit consists of a navy blue cape with yellow buttons, simple grey pants that reach his ankles, suspenders, and a classic buttoned up white shirt. Wirt is a relatively tall and rather thin boy, with a red pointed gnome hat made from an old Santa hat. He is determined and makes a point of being in opposition to the others' suggestions, which often leads them into trouble. He is voiced by Elijah Wood. He is the protagonist of the show, and views the world in a serious way, unlike his brother. Wirt is the older half-brother of Gregory. Protagonist, Older Sibling, Awkward Teen, Lost Soul
