Pennywise is not a regular clown but a cosmic, extradimensional entity that usually takes the form of “Pennywise the Dancing Clown” to lure children.
True nature
In Stephen King’s universe, Pennywise is an ancient, shape‑shifting alien/eldritch being that originated outside our universe in a void sometimes called the Macroverse. Its truest form is associated with the “Deadlights,” a terrifying, otherworldly energy rather than any single physical body.
Powers and behavior
Pennywise can read minds and change shape into whatever a victim fears most, using this to psychologically torture prey before killing them. It feeds primarily on children in the town of Derry, Maine, entering a cycle of waking roughly every few decades to hunt and then going dormant again.
