The Atlantic said of the character; "the scariest thing about Pennywise, though, is how he preys on children's deepest fears, manifesting the monsters they're most petrified by (something J. K. Rowling would later emulate with boggarts)."
In both the book and the films, It is an ancient alien creature, older than civilization, and in King's novel, older than our universe. It feasts on the flesh of humans simply because our fears are easy to manifest and they make us taste better.
According to It, when humans got scared, "all the chemicals of fear flooded the body and salted the meat". This is why he prefers to feast on children -- their fears are simple, pure, and powerful compared to the complex, pathological fears of adults.
However, It must surrender the the laws of whatever shape It takes. Pennywise's strength is also his weakness. For example, if he were to take the shape of a werewolf (as he does in the novel), silver bullets would harm him.
In their final battle, the Losers' Club was able to kill Pennywise by reducing him to a child-like form as they overcame their fears. In the moments before Pennywise died, his fear is reminiscent of Georgie's own, therefore closing the cyclical nature of Pennywise's murders.
And if his victim believes him to be powerless, he will become powerless. And so the group figures out that their best bet is, essentially, to bully the bully: They mock Pennywise, telling him he isn't scary. Humiliated, Pennywise begins to shrink, transforming into an almost Benjamin Button–like, melted clown-baby.
Stephen King's IT introduced readers to a one-of-a-kind creature that can take any form, the most common one being Pennywise the Dancing Clown, and as menacing as it is, this creature has one big enemy it's truly scared of: Maturin, the turtle.
He's a demon and the general idea is if you are not scare, it will only be harder for Pennywise to kill you as he needs to bait you. He can kill you if he wants to anytime and doesn't care. Although, if you are not scared, he will either leave you be for a little while or just kill you in the instant .
They reach the conclusion that Pennywise has all of the adults under some sort of spell that prohibits them from seeing him. The adults of Derry are shown to be villainous in their own right as well. The adults of Derry are shown to be true villains of the story in the same way as Pennywise.
It is a horrific and malevolent cosmic entity who is billions of years old and preys on Derry's people, especially children, feeding on their fears and using the writhing bright orange lights that comprised his own life essence known as "Deadlights", a dangerous and eldritch form of energy (which is used as a dark ...
Some time after the universe was created, Pennywise made Its way to Earth, crash-landing in what would eventually become Derry, Maine. Once it became inhabited with people, Pennywise began Its infamous quarter-century cycle, awakening from hibernation every twenty-five to twenty-seven years to feed.
Bob Gray or Pennywise, but his true form is an ancient eldritch entity from another universe who landed in the town that would become Derry by way of an asteroid and first awoke in 1715.
Though it is just before the next twenty-seven year IT cycle, this is our first glimpse of Pennywise in IT Chapter One. In the opening scene of the film, young Georgie Denbrough playing with a paper boat made for him by his brother Bill. He loses the boat down the sewer and faces Pennywise when he tries to get it back.
Pennywise slumbered beneath the Earth for millions of years, awaiting the arrival of Mankind. When the town of Derry was built in 1715, IT awoke and began a cycle of feeding on the fears of the people of Stephen King's Derry and then resuming hibernation for cycles of 27 to 30 years.

The spider-clown shrinks as the Losers hurl taunts at It, until it's tiny and weak enough that they pluck out its heart and squash it into nothingness. In the end, they defeat Pennywise by, uh, making him feel really bad about himself. It author Stephen King.
Also in the 2017 film, Georgie's death is changed. As well as having his right arm bitten off, Georgie is trying to crawl away but he was dragged into the sewers and devoured by Pennywise, with an unnamed older woman and her cat being the sole witnesses of the horrific scene, including before Georgie lost his arm.
The Losers confront Pennywise on how they've overcome their fears, and are no longer scared of the entity, causing It to shrink to a small weakened Pennywise. Mike rips out It's heart, which he and the Losers crush with their bare hands, finally killing It.
It has a low pain tolerance
Each time that Pennywise is harmed during his encounters with the Losers Club, it does not respond with anger and rage.
In fact, the balloons are considered in the fan theory to not only represent the deadlights – but that they also carry the souls of all the children Pennywise has devoured.
