Summary
Pennywise, also known as It, is the main antagonist of the novel by Stephen King, It, and it's various movie adaptations. A higher-dimensional monstrosity, It soon created a 3-dimensional avatar and sent in crashing onto the prehistoric Earth in what would become the fictional town of Derry, Maine. There, it would rise every 27-30 years to torment, kill and devour children.

Equipped with various nasty abilities and usually taking on the form of the so-called Pennywise the Dancing Clown to better gain the trust of its juvenile victims, It would return time and time again since it's first true attack in 1715, but one group of individuals that name themselves The Losers - ironically - went on to stop the abomination, defeating it every time it rises from 1960 to beyond the 2000's.
