Steve Williams (voiced by David Herman) -- Steve is an overconfident, bumbling park ranger who takes himself and his job way too seriously. Even though he has been "Ranger of the Month" at Brickleberry for several years, he does not appear to display good skills or even common sense. Steve's "Ranger of the Month" title means everything to him and he will do anything to keep it. Despite his extreme lack of intelligence, he knows the Brickleberry park very well because his father was also a Brickleberry ranger, so Steve was raised in the park. He dreamed of working at Brickleberry since he was a child in order to follow in his father's footsteps. He is shown to have a man crush on Viggo Mortensen. Woodrow "Woody" Johnson (voiced by Tom Kenny) -- Woody is a 55-year-old, abrasive ranger with a military background. In the "Crippleberry" episode, he mentions to Steve that he is technically a war criminal. He worked his way up to head ranger over his 30-year career at Brickleberry. He worked alongside Steve's father, but never searched for him when Jonah went missing. He always has the park's best interest in mind and struggles to boost the dwindling tourism numbers by any means. In "2 Weeks Notice", he accidentally confesses to Malloy that when his mother died, his father forced him to dress up in her lingerie, implying that he may have been sexually abused by his father. It is also revealed in season 2 that Woody was a former porn star named Rex Erection. Ethel Anderson (voiced by Kaitlin Olson in season 1, Natasha Leggero in season 2 and 3) -- Ethel is an attractive, 25-year-old female ranger. She was the top ranger at Yellowstone and was transferred to Brickleberry in an effort to get the park back on track (and because she was fired from Yellowstone for being drunk on the job). She is passionate for animals and nature and does her best to treat her co-workers kindly. Steve sees Ethel as a threat to his Ranger of the Month title, while Ethel sees Steve as a bumbling idiot. Ethel possesses extraordinary ranger skills, but is much more humble than Steve. Denzel Jackson (voiced by Jerry Minor) -- Denzel is a black ranger who is horrible at his job, but ca n't be fired because he works for a government agency. Denzel is a gerontophile, which occasionally gets him into hot water. Denzel finds his job challenging because he's afraid of bugs, snakes, and pretty much anything else that inhabits the woods. It was revealed in the first season that his father and father's father and grandfather's father were undercover cops, but Denzel has no interest in following in their footsteps. For the rest of the series it is not mentioned again. Connie Cunaman (voiced by Roger Black) -- Connie is a lesbian female ranger who has a large body, immense strength, and a deep voice that is often mistaken for a male. In "Gay Bomb", Connie admits she is a lesbian and it is revealed to the viewers that her strength is dubbed by her as "lesbian strength". Connie is capable of lifting massive objects, such as trees, bears, and even a real bomb. She is obsessed with Ethel and was turned away by her Evangelical parents for being a homosexual. On a side note, when Connie gets excited, her vagina makes growling noises similar to that of a stomach, requiring her to talk it down like a wild animal. Malloy (voiced by Daniel Tosh) -- Malloy is the last surviving member of his species Ursus loquacious that Woody has taken in and spoiled after Steve accidentally ran over and shot his parents, telling him a tourist did it. Woody lets him play video games all day and eat junk food. Malloy is very crude, racist, sexist, has a superiority complex, and in some ways is a narcissist. He openly hates the rangers and in addition, he enjoys putting them down and messing with them on a daily basis, especially Steve.
