A god of destruction, not just of our world, but of multiple worlds and even multiple universes. It originated in a vast cosmic void between worlds that has been called, at times, the Macroverse, and in King's Dark Tower series, the Todash Darkness, in a space It refers to only as the Deadlights.
In the novel, It is a shapeshifting monster who usually takes the form of Pennywise the Dancing Clown, originating in a void containing and surrounding the Universe—a place referred to in the novel as the "Macroverse".
Immortality: Its earthly avatar has existed on Earth for thousands if not millions of years. Its true form has existed even longer in the Macroverse (a void outside of time and space that surrounds our own universe).
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.
IT is comprised entirely of “deadlights,” pure evil energy. The deadlights originate from Todash Space, the monster-filled void that exists between words in King's universe. Just go with it. The deadlights have a hypnotizing effect on humans.
That is, when Pennywise morphs into a werewolf, he is subject to the same weaknesses as a werewolf, including silver slugs. In both the original novel and made-for-television adaptation, Pennywise is weakened using silver bullets melted down from earrings.
Down in the sewers, during their final encounter, it's much of the same. Mike brings the gun he uses to kill livestock, and the rest of the Losers come prepared with more rods. Beverly deals the final blow by putting one straight down It's throat.
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. Basically, children are delicious.
This is one of the most interesting Hollywood couplings we learned about in quite some time. Apparently, Pennywise and the Babadook are dating. In fact, they're in a long term committed relationship.
Muschietti appears to be implying Pennywise was a human familiar who It corrupted and then enjoyed so much It incorporated his shape into its file cabinet of monsters.
IT thrives on chaos; an exact 27-year pattern is way too predictable for a being of pure evil. Rather, IT wakes up roughly every three decades, and stays away for a different period of time.
Kersh is Pennywise's daughter.
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.
Pennywise's arch-enemy was a giant turtle
There he meets a Maturin, a god-like being who looks like a giant turtle and who created our universe by throwing it up. An opposing force to the self-proclaimed "eater of worlds," Maturin drops some pearls of wisdom before Bill faces off against Pennywise.
For this reason, and others, Pennywise can be classified in the same category as The Great Old Ones of H.P. Lovecraft, including Nyarlathotep, Azathoth, and Cthulhu, which were later classified as Elder Gods.
In the movie, Pennywise says “They all float down here. You'll float, too”, referring to the floating bodies of the many victims that have been dragged to the sewers and… well, you know the rest.
Throughout Stephen King's It, Pennywise is referred to as a male, but author Stephen King pulled a fast one on readers in the It book ending by revealing the creature's true form was a pregnant spider, implying that it is, in fact, biologically female.
Throughout the summer and their trials against Pennywise and the school bullies, the Losers realize that none of the adults in Derry can actually see Pennywise or the horrors he is committing against the children of Derry.
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.
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.
Answer and Explanation: Georgie is killed by Pennywise in the form of a clown in the sewer in the beginning of the book.
Yup! 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 .
Superhuman Strength: It can tear the heads and limbs of human bodies with extreme ease, either with arms or mouth (as Pennywise or any humanoid form). Superhuman Speed: Bill notes that It can move at extreme speeds, claiming that it was way faster than an "express train".
It has a low pain tolerance
Not many people can say that they have harmed Pennywise before. However, those that have may notice something very interesting about the dancing clown. It certainly does not have a very high pain tolerance for a frightening demon.
