Liane Cartman is the mother of Eric Cartman. She makes many appearances throughout the series and is considered to be one of the most prominent out of all the South Park parents. She first appears in the Season One episode "Cartman Gets an Anal Probe". Liane is a good-natured individual but with a definite edge to her. Her voice is usually kind and soft (but sounding even more sweet in the 4th through 7th seasons when she was voiced by Eliza Schneider) and her actions are usually to aid others,
