Title: Eric Cartman
Content:  Eric Theodore Cartman, often referred to just by his surname, is a main character in the adult animated television series South Park, created by Matt Stone and Trey Parker, and is voiced by Parker. He is one of the series' four central characters, along with Stan Marsh, Kyle Broflovski, and Kenny McCormick. A prototypical version of Cartman (called Kenny) first appeared in the 1992 animated short, Jesus vs. Frosty, later appearing in the 1995 animated short Jesus vs. Santa, and first appeared on television in the pilot episode of South Park, "Cartman Gets an Anal Probe", on August 13, 1997. Cartman is an elementary school student who lives with his mother in the fictional town of South Park, Colorado, where he routinely has extraordinary experiences atypical of a small town. Cartman is aggressive, savage, prejudiced, arrogant and narcissistic since his character's inception, being described by Stone and

Content:  Eric Theodore Cartman first appeared in the 1992 short series The Spirit of Christmas and is voiced by Trey Parker. Cartman has been portrayed as aggressive, prejudiced and emotionally unstable since his character's inception. These traits are significantly augmented in later seasons as his character evolves, and he begins to exhibit psychopathic and extremely manipulative behavior. He is depicted as highly intelligent, able to execute morally appalling plans and business ideas with success. His intelligence goes further, as Cartman is shown to be a multi-linguist, able to speak many different foreign languages fluently. Among the show's main child characters, Cartman is

They would naturally reproduce these voices in the initial seasons of South Park. Although he had originally voiced Cartman without any computer manipulation, Parker now does so by speaking within his normal vocal range with a childlike inflection. The recorded audio is then edited with Pro Tools, and the pitch is altered to make the voice sound like that of a fourth grader. Parker says to achieve the effect of Cartman's voice, he simply uses the same technique when voicing Stan while "adding a lot of fat to it".
Title: List of students at South Park Elementary
Content:  Eric Cartman, voiced by Trey Parker, is commonly referred to as just Cartman. He is one of the show's four main characters and one of the most popular and iconic. He is obese, obnoxious, antisemitic, racist, sexist and spectacularly sociopathic in his attitude. Most other pupils are alienated by Cartman's insensitive, often misogynistic, and bigoted behavior, though they are occasionally influenced by his obtrusive, manipulative, and propagandist antics. He often tricks Butters. Cartman's role in the series varies from episode to episode. Eric plays the role of a wizard in South Park: The Stick of Truth and plays the role of his alter-ego the Coon in South Park: The Fractured but Whole.

Content:  Matt Stone, is a common topic throughout the series. Cartman—loud, obnoxious, and obese—is sometimes portrayed as the series' antihero and whose anti-Semitic attitude has resulted in an ever-progressing rivalry with Kyle. Kenny, who comes from a poor family, wears his parka hood so tightly that it covers most of his face and muffles his speech. During the show's first five seasons, Kenny would die in almost every single episode before returning in the next without explanation. Stone and Parker perform the voices of most of the male South Park characters. Mary Kay Bergman voiced the majority of the female characters until her death in 1999. Eliza Schneider (1999–2003), Mona Marshall (2000–present), and April Stewart (2003–present) have voiced most of the female characters since. A few staff members such as Jennifer Howell, Vernon Chatman, John Hansen, and Adrien Beard have voiced the other recurring characters.
Title: List of South Park families
Content:  Liane Marie Cartman, originally voiced by Mary Kay Bergman and later by Eliza J. Schneider and April Stewart, is the generally sweet-natured mother of Eric Cartman; though in later seasons, she is a more proactive mother who does not tolerate his antics or foul language. Her promiscuity, often with total strangers, was a running gag initially. It seemed as though all of the adults in South Park had slept with her (probably the women, too). Although in episode 7, she is indicated to be a "crack whore", she says in "The Poor Kid" that she has not done drugs in some time, and works two jobs, even though she and Eric are the second poorest family in South Park (at least of those whose children attend South Park Elementary) after Kenny McCormick's. It is first revealed that she is a hermaphrodite (and so is Eric's father), though in episode "201" it is revealed that Eric's real father is Jack Tenorman, the father of his nemesis Scott Tenorman a member of the 1991 Denver Broncos, and the ruse about her being a hermaphrodite was made up to maintain the Broncos' reputation since "they were having a good year".

As a joke, Parker and Stone responded by offering low-profile, non-speaking roles, most of which were accepted; George Clooney provided the barks for Stan's dog Sparky in the season one (1997) episode "Big Gay Al's Big Gay Boat Ride", Leno provided the meows for Cartman's cat in the season one finale "Cartman's Mom Is a Dirty Slut", and Henry Winkler voiced the various growls and grunts of a kid-eating monster in the season two (1998) episode "City on the Edge of Forever". Jerry Seinfeld offered to lend his voice for the Thanksgiving episode "Starvin' Marvin", but declined to appear when he was only offered a role as "Turkey #2".

Stewart was originally credited under the name Gracie Lazar,

Throughout the show's run, the voices for toddler and kindergarten characters have been provided by various small children of the show's production staff.
