American Scream is a DC comics super-villain and malevolent cosmic-entity, the evil side of Uncle Sam it personifies all that is wrong in American culture just as Uncle Sam embodies all that is pure in said culture - while obviously the generals of what is wrong in American culture varies wildly from individuals the American Scream embodies such things as jingoism, racism, patriarchy and other forms of intolerance - making it a sinister parody of the heroic Uncle Sam as well as a mockery of American heroes in general.

The creature is immense in power, rivalling Uncle Sam, able to warp reality to its liking it feeds on negativity and can make others behave in stereotypical ways that furthers its goal to twist the concepts of Uncle Sam and "make the world a stranger place".
