Big Black Scary Monster

The Big Black Scary Monster is first seen in the episode City on the Edge of Forever (also known as Flashbacks). It is the main antagonist in the episode but of course cannot be considered real due to the very nature of the episode itself. It is seen in the episode killing two children one of which is Kenny, but later in the episode it is remembered as giving all the children ice cream in a signifcantly more friendly manner. Coincidentally, this monster was once used to scare South Park Kindergarteners into behaving. It eat Boy with Red Shirt.
