Wirt is one of two main protagonists of the Over the Garden Wall. He views the world in a serious way, unlike
his younger half-brother, Gregory. He is determined and often makes a point of being a contrarian, which
frequently leads the pair into trouble.
Wirt is a pessimistic realist in many ways, but also has a naïve and childish side to him. He is easily
scared and surprised, and even though he is far more perceptive than his brother, he is very much still a
kid. Throughout the storyline of Over the Garden Wall, Wirt has to struggle to remain optimistic against
impossible odds. His tendency to think negatively is what made him an easier target for the Beast to drag
down into despair. Wirt's brother, Gregory, is a parallel of his brother that pulls out the playful, jovial,
childlike side of Wirt. He is also shown to have an interest in poetry, as he is often seen spouting
melancholic verses. Wirt is shown to have low self-esteem and that he perceives himself to be an outcast,
possibly due to his more sensitive interests like poetry and interior design.
Gregory, affectionately nicknamed Greg, is Wirt's younger half-brother. He is a very energetic boy who always
has a smile on his face and very wild ideas on his mind. He's endlessly fascinated by everything, including
things that would normally seem scary. He has a habit of wandering out on his own. He has a pet frog, which
he found before his descent into the Unknown, giving it a different name every chapter (Kitty, Doctor,
George Washington, etc). He also carries a rock, that will randomly make Rock Facts. He is the deuteragonist
of the show.
Greg is the happy-go-lucky optimist of the trio, often remaining positive and unconcerned even in the face
of danger and impossible odds. This is likely due to the fact that being so young, Greg is incapable of
grasping the true nature of his and his brother’s situation and instead views everything that happens to
them with a light-hearted innocence. His outlook remains unaffected even as the Beast tries to tempt him
into despair. He’s a free spirit and is content marching to the beat of his own drum, showing little
inhibition when it comes to expressing himself and often getting sidetracked/wandering away from the group
whenever it suits him. Greg wholeheartedly believes that he can do anything when he sets his mind to it, and
he refuses to give up in even the bleakest of situations.
Beatrice is the tritagonist and the false antagonist of the series. She is a talking bluebird that
accompanies Wirt and Gregory, giving little lines of advice to them every now and then, and is described by
her voice actor to be somewhat of a grumpy bird. Her relationship with the two brothers evolve throughout
the series, even though she isn't very openly caring. Most of the time, Wirt seems to believe that she
doesn't enjoy the company of Gregory and himself.
Beatrice is portrayed as a very clever and headstrong girl. She is emotionally closed off and doesn't easily
convey or show affection. She was, perhaps, a very angry or aggressive child, as she had thrown a rock at a
bluebird, which then cursed her and her whole family. After her transformation, Beatrice was ridden with
guilt and would do anything to transform her family back into humans. She thinks her family resents her
because of her actions, when in reality they miss her and love her dearly. She develops a friendship with
Wirt and Greg, even though she nags them and points out their flaws.
The Woodsman is a supporting character in Over the Garden Wall. He is presumed to be one of the triantagonist of the series but later becomes an ex-follower of the Beast. The Woodsman is tasked to chop Edelwood trees, as the Beast told him to, so that his daughter's soul would remain alive and lit in the Dark Lantern the Woodsman carries throughout the series. Despite Wirt and Greg being wary of him, he often does his best to help the two boys and tries to keep them from succumbing to the Beast.
