It: Chapter Two's ending is a pretty dramatic departure from the original novel, which finds the characters defeating Pennywise—a transdimensional being—with the help of a similarly transdimensional space turtle named Maturin. (Seriously.)
Literature. 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".
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.
There was a human Pennywise the Dancing Clown, but IT just takes his form. In the movie canon, Pennywise the Dancing Clown was a real person whose image IT decided was a terrifying enough basis for his child-scaring campaign.
Pennywise's origins are briefly explored in both the book and It: Chapter Two, where it's revealed that he is a being that crash-landed on Earth from another dimension hundreds of years ago.
Kersh is Pennywise's daughter.
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.
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".
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.
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.
Humiliated, Pennywise begins to shrink, transforming into an almost Benjamin Button–like, melted clown-baby.
It may reproduce via parthenogenesis, like the copperhead snake, or something similar. It never did before because it never HAD to, or even thought to. But after almost being killed by the losers the first time, it realized it may in fact NEED to reproduce to continue its existence.
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.
While it's unclear if it was ever shot, a deleted scene from the IT 2017 script saw Pennywise actually eat a baby in front of its mother. There are lots of disturbing scenes in Stephen King's original IT novel. Anyone who's read that gargantuan tome can readily attest to that fact.

And what do dead bodies do in water? That's right — they float.
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.
Frightening & Intense Scenes (22) It disguises itself as many frightening things in the movie. Pennywise can morph his mouth into a giant gaping mouth with layers of sharp teeth which he uses it mangle and eat his victims. This is all done with CGI.

Film: At the house on Neibolt Street, the kids basically do a bunch of damage by impaling It with rods. It looks like they get these weapons from the rusty wrought-iron fence of the house itself. Down in the sewers, during their final encounter, it's much of the same.
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.
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.
Still, the film gives viewers a pretty good sense of who Bill (Jaeden Lieberher), Beverly (Sophia Lillis), Ben (Jeremy Ray Taylor), Richie (Stranger Things star Finn Wolfhard), Eddie (Jack Dylan Grazer ), Stanley (Wyatt Oleff), and Mike (Chosen Jacobs) are.
