Sheila Broflovski

Sheila Broflovski is Kyle's mother and a regular antagonist (albeit not by choice) in the comedy series "South Park". However, she is the tertiary antagonist in the movie.

Although she means well Sheila is a shameless control freak and morality-obsessed madwoman who constantly interferes with the town in ways that are often disasterous and detrimental, she views children as innocent and vulnerable (despite the children of South Park often being smarter than the adults) and thinks that the slightest bit of controversial content will corrupt them.

To this end she has staged a number of crazy stunts to "protect" the youth of South Park or force tolerance, often taking it to the extremes - she has even tried to declare all-out war on Canada (with the now famous song "Blame Canada").

Sheila's constant ability to vex others and interfere has earned her much hatred from Eric Cartman, who inventively created a song to mock her entitled "Kyle's Mom's A Big Fat B*tch" (unfortunately for Cartman Sheila's ability to interfere went beyond even his knowledge and she caught him singing the song).
