Xavier (voiced by
Vernon Chatman) is a well-meaning yet naïve and oblivious
faun-like shaman wanderer with
delusions of grandeur. Xavier often brings destruction to his environment and those around him in his attempts to right what he sees as wrong or help others with their problems. Xavier's left hand is a snake from the elbow downwards; it usually acts like an ordinary hand, but in the episodes "The 6th Teat of Good Intentions" and "El Tornadador", it appears to possess its own consciousness and speaks to Xavier directly. Xavier also has brown fur, a bird-like beak in place of a nose, and ocular
heterochromia, having one brown eye and one blue. Xavier's purpose seems to change slightly with each episode, with the initial plot setting him as a wandering
philosopher, aspiring "wise man" or sage of sorts whose intent on
hermitism seems to give references to Native American
vision quests. Of initial importance seems to be Xavier's search for an answer to the abstract question, "What doth life?". Much of the first season focuses on his search for the person who killed his father, while the second season puts focus on his search for his mother, whom he believes to be alive after digging up her grave. In the
series finale, Xavier finds his mother in a
lunatic asylum and has sex with her, which causes Xavier to see himself as the human he apparently always was. •
Chief Master Guru (voiced by
Jim Tozzi) – This supposedly
Indigenous shaman took Xavier in after he was orphaned, and taught him mystical and spiritual practices (one such teaching being the power to heal others with the use of a fictional instrument called a "shakashuri"). The Shaman features frequently in flashbacks, and—despite Xavier's adulation—is shown to be abusive, sadistic, bullying and cruel. • '''Xavier's father''' (voiced by
Jim Tozzi) – Being dead, Xavier's father only appears in flashbacks and visions. Xavier says he wants to avenge his father's death, but in one such flashback his father insists that Xavier himself killed him. In a flashback, however, (one which Xavier later denies as being true), Xavier's father takes Xavier to a remote location and abandons him as a child, only leaving him with a bicycle as a means of compensation, before crashing into a truck and exploding. • '''Xavier's mother''' (voiced by
Alyson Levy) is generally seen in flashbacks as constantly either drunk, drug-addled, or having sex with men or animals. Xavier's mother seems to have hated him for his appearances, calling him a "demon child", among other names. In "Braingeas Final Cranny", it is revealed that Xavier's mother tried to abort Xavier, though she found out that she was too far along into the pregnancy to do so. She instead allowed the doctor to torture Xavier with a cattle prod. •
Computer (portrayed by
John Flansburgh) is a sentient computer used by Xavier for analysis and information. He appears as a jerkily edited live-action actor set in front of a black and white background. ==Creation and contents==
