3. Cartman from South Park
South Park’s Eric Cartman is a shining example of American alpha males in the early 21st century.
Here’s what Wikipedia has to say about the character:
Cartman has been portrayed as aggressive, prejudiced, arrogant, and narcissistic since his character’s inception; Stone and Parker describe the character as “a little Archie Bunker”. These traits are significantly augmented in later seasons as his character evolves, and he begins to exhibit extremely psychopathic, sociopathic and manipulative behavior, and also be depicted as highly intelligent, able to execute morally appalling plans and business ideas with success.
