It (creature)

It (also commonly known as Pennywise) is an ancient alien/eldritch monster and the title character and the overall secondary antagonist of the Stephen King multiverse, serving as the titular main antagonist of the It Miniseries and it's two film adaptations IT and IT: Chapter Two.

About
It is a shape-shifting creature known as a Glamour who is billions of years old. Although It lived on planet Earth for many years, It originated in a void/dimension outside the regions of space known as the Macroverse. Since Its true identity is unclear, due to its shape-shifting abilities and being from another universe, Its real name and species are called Deadlights, but few know this, which is why it is referred to as IT. The form of a female spider seems to be Its true physical form on Earth (or at least that is the closest thing the human mind can comprehend), living deep below the fictional town of Derry, Maine. It can morph into any other human animal, nonhuman animal or object (including combinations thereof). This ability is useful for, A) appearing as the target's loved ones or friends to manipulate them or lure them into a trap or B) appearing as the target's worst psychological fear. However, Its favorite and most common form is that of a circus performer named "Pennywise the Dancing Clown," as most small children love a clown and generally, it seems that the people in Derry happily accepted the presence of a stray circus performer. At the same time, many people are afraid of clowns, making them an easy fear to exploit.

Its real name (if indeed, it has one) is unknown. Although, several times in the novel, It calls itself by the name Robert “Bob” Gray. This may be an allusion to real-life child cannibal Albert Fish, who reportedly used the name "Robert Gray" as an alias. He may also get his first name from Robert "Bob" Bell, the man who originally portrayed Bozo the clown.

Its primary goal is to feed on humans, generally preferring children over adults since they were easier to scare and manipulate. According to the creature, frightened flesh tastes better and uses fear to "salt the meat".

Origins
It originated in an undiscovered void containing and surrounding our entire Universe, another far off universe referred to as the "Macroverse." (A concept related to Todash Darkness from The Dark Tower Novels).

Other evidence from this series suggests It is the creation of a separate omnipotent creator referred to as "the Other" (who may be the entity Gan). This "Other" helps the defeat of it at the end, and may also be responsible for the creation of "The Turtle", who is It's natural enemy. In It the novel, the Turtle refers to It as his "brother".

It may be one of, or a Twinner of, the six greater demon elementals mentioned by Mia in Song of Susannah (as the Spider is not one of the Beam Guardians). It's possible that there are other creatures of the same species as It, due to the fact that It is revealed to be pregnant.

History
It arrived on Earth in a massive cataclysmic event similar to an asteroid impact, landing in a location in North America that would eventually become Derry, Maine. Once people settled over this location, It adopted its usual pattern of a 27-30 year hibernation, waking to kill and eat. Each awakening and return to hibernation is sometimes marked by a violent and tragic act, such as a mass murder, suicide or weather event. In the period between, a series of child murders occurring in Derry are never taken too seriously or solved. It is outwardly explained that a series of murders, no matter how gruesome, don't get reported if they happen in the small town. However, the real reason is that the influence of It prevents anyone from investigating too deeply.

Timeline (novel)

 * 1715 – 1716: It painfully awakes.
 * 1740 – 1743: It starts a three-year reign of terror that culminates in the disappearance of over three hundred settlers from Derry Township (similar to the lost Roanoke Colony, which was founded as a logging town.)
 * 1769 – 1770: It awakes again.
 * 1851: IT awakes when a man named John Markson poisons his own family, then commits suicide by eating a white nightshade mushroom, causing an excruciating death.
 * 1876 – 1879: It awakes, then returns to hibernation after murdering a group of lumberjacks who were later found near the Kenduskeag Stream.
 * 1904: It awakes when a lumberjack named Claude Heroes murders a dozen men in a bar with just one axe. Heroux was promptly pursued by a mob of townsfolk and hanged. In 1985, when Mike asks a witness, if he saw anyone he didn't know that night or seemed out of place.  He remembered seeing "a comical sort of fella". He also said he had seen him a few more times since.
 * 1906: It returns to hibernation when the Kitchener Ironworks explode, killing 108 people, 88 of whom were children at an Easter egg hunt.
 * 1929: It awakes when a group of Derry citizens ambushes and kills the Bradley Gang, a group of robbers and murderers. The town, including its police chief, pretends it never happened. However, a witness later recounts the tale to Mike Hanlon, including seeing a clown in farmer's attire participating in the slaying.
 * 1930: It returns to hibernation when the Maine Legion of White Decency, a Northern counterpart to the Ku Klux Klan, burns down "The Black Spot", a nightclub known to cater to African-Americans at the nearby army base. IT appears at the location as a giant bird with balloons on its wings, witnessed by Mike's father William Hanlon.
 * 1957: It awakes when Dorsey Corcoran is beaten to death by his stepfather, Richard Macklin. In October, Georgie Denbrough dies from blood loss, when his arm is torn off by Pennywise. This prompts Bill Denbrough (Georgie's older brother) to investigate, leading to the discovery of IT. He, along with several other victims of IT's torment, performs the Ritual of Chüd, which wounds It and forces it to return to an early hibernation.
 * 1984: It awakens when three bullies assault Adrian Mellon and Don Hagarty, a homosexual couple. The bullies throw Mellon off a bridge and IT, in the form of Pennywise, attacks and kills him.
 * 1985: It is finally defeated and physically killed in another Ritual of Chüd by the adult Bill, Richie, Beverly, Eddie, and Ben.
 * In the 1990 adaptation, events occur slightly later, with Georgie's disappearance occurring in 1960 and ITs death in 1990.

Timeline (2017 film)
The 2017 film places those events in 1989. This adaptation also introduces new events that cannot be placed canonically:


 * Derry starts as a beaver camper until 91 people vanish. The rumored cause is plague or slaughter by Indians, but there are no signs of an attack. The only evidence is the presence of bloody clothes at the Well House.
 * 1908: IT awakens after the Kitchener Ironworks explosion, where 102 people die (88 kids and 14 adults).
 * 1935: IT awakens after the Bradley Gang shootout.
 * 1962: IT awakens when the The Black Spot is burned down by a cult.
 * 1989: IT awakens to eat kids for a year before going into hibernation. Georgie Denbrough dies by Pennywise biting his arm off and dragging him into the sewers. Bill Denbrough (Georgie's older brother) and the Losers' Club investigate, which culminates in his (and other victims of IT) finding of its den and forcing IT to go back into hibernation when the monster falls into a deep well. The Losers' club learns from Beverly about the future and they swear that, if IT returns one day, they will come back to destroy it once and for all.

Timeline (2019 film)
27 years after the events of the first film, It resurfaces when a group of homophobic teenagers beat up and toss a gay man named Adrian Mellon off the bridge. He then slaughters Adrian in front of his lover before presumably using his blood to write a message to Mike about its return. As such, It wasted no time in hunting the children of Derry, such as when it uses empathy to lure a young girl named Victoria into getting closer to it under the false assumption that he'd help make the birthmark on her face disappear. To further torment Bill, It sends him a skateboard, explicitly letting him know that it was going to go after the young Dean next. Realizing that Dean was heading to the carnival, he chases after him into the hall of mirrors. Unfortunately, It gets the upper hand and gruesomely kills the young boy in front of him. Horrified to have lost another young boy after Georgie, Bill decides to head to the Neibolt house to personally kill It after Henry wounds Mike and Eddie.

After each member of the Losers Club went down their own quests to retrieve artifacts from their pasts to complete the Ritual of Chud, the ritual seems to work when it traps Its deadlights inside of the vase, but it goes awry. A giant version of Pennywise emerges, revealing that the original natives who had performed the ritual were immediately slaughtered by It. This version of It is a combination of its default form Pennywise the Dancing Clown and the Giant Spider as described in the book. It then warps the Losers Club into different nightmarish scenarios, but they inevitably overcome their fears. It traps Richie in its deadlights, forcing Eddie to grab the pole Beverly gave him earlier and attacks Pennywise with it under the belief that it could kill It. Unfortunately, Pennywise impales Eddie with one of its spiderlike appendages, swings him around like a ragdoll, and tosses him, leaving him with a large wound in his abdomen.

This one act proves to be its undoing, however, when the Losers Club realize that in order to defeat it, they had to make it believe it was smaller. Despite its insistence that it was the "eater of worlds," the remaining Losers insult the clown repeatedly until It is forced into a smaller, infantile form. It attempts to lash out at Mike, but is too weakened. To its horror, Mike reaches into its chest and grabs its beating heart. It tries to grab it to no avail, and is left crying like a baby, its final words being "Look at you...you've all grown up!" with weak laughter.

The Losers each mutually take ahold of the heart and crush it slowly. It reacts in pain until the heart exploded into a pasty substance, killing it and avenging everything IT has caused. It falls silent as its body turning to ash. After its death, Richie tries to coerce Eddie's corpse awake, not accepting that he was truly gone. His attempts of taking the body with him fail when Its lair and the Neibolt house start to crumble and collapse in response to its master's demise. The Losers are forced to leave Eddie's body in It's lair, and the Neibolt house collapses on itself, sinking into a hole in the ground.

Personality/Behavior
The reasons behind It’s actions is that it eats for its own survival and satisfaction and then it goes dormant usually after a year's worth of feeding. It is a deadly predator that primarily hunts for food. But only if it can scare its prey before feasting on it.

It is a predator of humans, and prefers children to adults. Most importantly, It desires to consume those it has made terrified of Itself. The creature implies that this enhances the flavour. It's preference for children prey may be due to how they taste, but also may be due to the fact that children are easier to scare.

Its only goals are to eat and sleep. It will hunt and kill for a year, before entering a 27-year dormancy. It manipulates the awareness and attention of the People in Derry, both to mask its activities and isolate its victims. This enforced apathy and lack of awareness also masks the anomalous murder spikes during its active phase.

It manipulates its prey and the town through both mundane and psychic means. In the most grand sense, It uses its power to maintain the prosperity of Derry despite the gruesome murders that regularly occur there, thus securing its food supply.

It will manipulate its prey by promising them what they want, but can also determine their psychological fears and utilize them to provoke or cow those it faces. In the guise of Pennywise, it can be disarming, charming and seemingly nice to the kids it hunts, usually to lure them into secluded spots before attacking.

It has psychic influence enough to keep the entire town of Derry in a subtle, apathetic ignorance to its activities. Adults are less inclined to care about the missing persons of the town and do not react in any intense manner when violence occurs even in front of them. It is able to make its prey experience hallucinations that are very hard to discern from reality.

It has some ability to control the actions of others, most blatantly when It provokes Henry Bowers psychotic tendencies to kill his father and friends, and later acts as its agent in hunting the Losers. Even 27 years later Bowers remains submissive to It.

2017/2019 Adaption
In this iteration, It is more directly impacted by the mental state of those it attacks and, conversely, is vulnerable to it's own mental state.

It is less able to harm or kill someone who isnt afraid of it and is vulnerable to the Losers Club when they become angry and assault it, nearly killing it in the process. Ultimately, its form is a reflection of its mentality. When the Losers confront it with its weakness, childishness and their lack of fear, it progressively becomes smaller and smaller.

It is able to take any shape it desires, but is in turn bound to the nature of that shape. This proves to be its undoing: Eddie nearly chokes it when it takes the form of a leper and is small enough for him to do that. When sufficiently weakened, the Losers kill It by crushing the heart it must have in the form of Pennywise the Dancing Clown.

Appearance
No one knows the true form of IT since it first existed in an inter-dimensional realm referred to as "deadlights". Bill Denbrough comes close to see the "deadlights", but defeats IT before this happens. The true form of the "deadlights" exists outside the physical realm. Any living being that sees the "deadlights" goes insane almost instantly. Bill comes dangerously close to seeing the deadlights and the shape behind the shape for a brief moment. He described IT as an endless, crawling hairy creature made of orange light.

Throughout the novel, IT is generally referred to as male; however, late in the novel, the characters come to realize that IT is most likely female, due to its true form in the physical realm being that of a giant pregnant female spider. This revelation prompts Audra Denbrough to say, "Oh, dear Jesus, IT is female." This, however, is not its true form; it's just the closest representation of it in our universe. Due to its pregnancy, it’s very possible that a male of the same species as IT existed at one time.

Powers and Abilities

 * Lower-tier Omnipotence: IT has an immense amount of power with only Maturin being its equal and Gan its only superior.
 * Telepathy: IT can detect emotions and memories of an individual, though apparently not thoughts, at least not from those who possess enough courage or willpower. It uses this ability to exploit fears, but also to implant thoughts. IT can also communicate through the mind, as seen with adult Richie Tozier (in the library) or adult Henry Bowers (at Juniper Hill in the novel).
 * Mind Control/Possession: IT can control the minds and actions of a person or several people simultaneously. This is demonstrated by affecting the minds of Derry citizens (at least those with weaker wills) to make them indifferent about any terrible events that they see. Evidence suggests that this control does not extend beyond Derry. The text also suggests that IT can erase memories or knowledge. Also, IT takes control of Norbert Keene's body to get Eddie to leave Derry.
 * Shapeshifting: IT can transform into any kind of being, including forms that may not be physically possible or exist in reality. This ability is not restricted by space or uniformity, as IT can appear in multiple places as multiple beings. In the novel, when transitioning forms, its body becomes an orange amorphous goo. Additionally, changing form in this manner appears to exert energy, as when IT is injured, it reverts to a giant spider. However, this form is only the closest the human mind can understand to its true one and not exactly what the children see. IT also has limitations on its appearance depending on who is seeing it and how afraid they are. For example, when Bill and Richie enter the house on Neibolt Street, Richie sees IT as a werewolf while Bill sees it as Pennywise, instantly realizing that "this is the clown that killed Georgie".
 * Illusions: IT seems to have no limit to what illusions can be created, but primarily uses them to instill fear, which means they must be realistic enough to do so. These illusions are physical (they can be touched and last beyond any given amount of time, though some of it may also be physical matter generated by IT, such as the blood left in Beverly's bathroom that only she and the other Losers could see) and can include smell (such as popcorn or rotting corpses). Also, IT can make its illusions visible only by certain people. Sometimes, when the victim sees through the illusion, they will cease to exist (although this may be the will of IT). However, one must see through the illusion perfectly. It is quite possible that some of his illusions are more akin to hallucinations that he telepathically plants in the minds of his victims using their fear, with the elaborate and apparently reality-bending visions (such as in IT: Chapter Two, where Bill relives his memories of first seeing IT in the form of Georgie in the basement of his old house, all while actually being submerged in underwater) having no true effect on the real world.
 * Invisibility: IT can appear (usually as Pennywise) to only certain people and stay invisible (in both sight and sound) from others. This is seen in a few instances, like when adult Beverly encounters Pennywise at her former home or when adult Ben Hanscom encounters it in the public library. This suggests that either A) only those aware of IT's existence are able to see them when invisible or B) IT can control who to appear visible by will. When it helps Henry Bowers escape Juniper Hill, one of Henry's cellmates and a guard witnessed it being next to him.
 * Telekinesis: IT can make inanimate objects fall, float around, and or behave supernaturally without touch. This includes locking doors, bending space-time, gravity, and remotely adjusting electronic devices.
 * Psionics: IT can steal people's souls and entrap them within the "deadlights". At the end of the story, a psychic storm nearly wipes out the town of Derry.
 * Chlorokinesis (plant manipulation): When IT, in the form of a leper, encounters Eddie, it touches several plants and causes them to die. This is not an illusion as the effect persists long after.
 * Weather Control: IT may be able to affect the weather in Derry's region. On more than one occasion when the Losers face it, the weather changes into a thunderstorm (most notably at the final confrontation which actually results in the devastation of Derry's downtown region).
 * Teleportation: IT can teleport to any location within Derry. However, it cannot seem to leave the city. This may be because, as Bill says "Derry is IT" and "IT is Derry."
 * 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".
 * Invulnerability: While IT is clearly not invincible, it can heal at superhuman levels, but the rate tends to vary for unknown reasons. In the 2017 film, IT is stabbed through the head with an iron spike, which merely disorients it, as it is able to retreat into the sewer. In the novel, when IT manifests as a bird, Hanlon hits the bird's eye and feet with broken tiles, the bird retreats. When Bill and Richie encounter IT as a werewolf, it can almost instantly regenerate after being shot in the head with a handgun. IT is not a true physical entity, thus cannot be killed or harmed by conventional means. The Ritual of Chud is the only known way to truly harm and kill it. IT's resilience can also be affected by the form it takes, as most humanoid forms that it takes can be harmed in some way, as it must abide by the limitations of each of its forms.

Weaknesses
It underestimates and scorns all of mankind. In many cases, it leaves an open escape route for victims and lets them run away. Because of this narcissism, It makes mistakes and does illogical things.

The presence of courage and heart are Its main weaknesses. This appears to have a psychological effect that instills fear and enables it the inability to function properly in its physical form.

Given that it feeds on fear, it makes sense that courage and heart can overcome it. Once the Losers are united, their strong shared will and love for each other successfully overpowers It. This allows them to form a psychic connection and "send power" to each other, even across distances.

It can be taken by surprise and can be physically assaulted if the attacker demonstrates no fear of it. Additionally, "belief" can affect It, such as the use of silver (which is a fictional weakness of supernatural entities) and an inhaler believed to contain battery acid.

The novel states that It must obey the laws of its form. This means that It possesses the vulnerabilities of whatever form it take, such as a vampire's vulnerability to sunlight or winged leeches obeying physics of flight.

During times of hibernation or healing, It may be vulnerable to surprise attacks. However, other books in the Stephen King universe (such as Dreamcatcher and Hearts in Atlantis) imply that IT may still be alive at the end of the story.

Other beings like Gan, who is superior to It, and Maturin, who is its equal, could kill It.

It by Stephen King
IT assumes thirty-two forms in the novel.


 * Pennywise the Dancing Clown: The main and favorite form that the creature takes. Pennywise wears a baggy silk suit of silver with orange pompoms and a collar ruff. He has a white face and a bald head, with red hair on either side. His mouth has a red clown smile. He wears large white gloves and is usually carrying a bunch of balloons. Stephen King based his appearance on Ronald McDonald, Bozo the Clown, Clarabell the Clown, and John Wayne Gacy.

In the 1990 miniseries, the outfit is more colorful with orange pompoms, blue sleeves, and a yellow body. In the 2017 movie, Pennywise returns to having a silver suit, similar to Italian opera clowns, and orange hair. His face has two red lines starting above his eyes, streaming down the cheeks, and ending at the corners of his mouth. His nose is not genuine but painted red. Most often, his eyes are orange, but IT can change them to appear more familiar. They also are often looking in different directions.

The form of a friendly and funny clown is the easiest to invoke a sense of safety and comfort without needing to know anything personal about the victim, thus why IT uses it so often.


 * George Denbrough: IT appears as Georgie to Bill throughout each adaptation in various places.
 * Dorsey Corcoran: Eddie Corcoran's brother, who was murdered by his abusive stepfather for climbing on a ladder in their garage.
 * The Creature from the Black Lagoon: This form scares Eddie Corcoran, a classmate of the children, when he is afraid to go home and show his dad his report card.
 * Betty Ripsom: One of IT's victims (in 1957), her voice is overheard by her parents through a drain.
 * A Giant bird: Resembles a combination of a crow that attacked Mike Hanlon as a baby and Rodan, a giant Irradiated Pteranodon which first appeared in a 1956 Japanese monster movie of the same name.
 * The Werewolf from the 1957 horror film I Was a Teenage Werewolf: IT takes this form during the encounter with Richie and Bill while in the mansion on 29 Neibolt Street. (It is even wearing a Derry High School blazer.)
 * A leper/diseased vagrant: When Eddie first encounters IT under the porch of the house on 29 Neibolt Street. Eddie assumes the man has leprosy when it is, in fact, untreated syphilis.
 * The Mummy from the 1932 Boris Karloff film: Ben Hanscom recalls seeing a mummy in Pennywise's clown costume walking towards him on the frozen canal, carrying balloons that float counter to the wind.
 * The Crawling Eye from the Hugh Beumont film: The Crawling Eye encounters the children under the city.
 * Alvin Marsh: Beverly's abusive father.
 * A swarm of winged leeches: Leeches who attack Patrick Hockstetter.
 * A school of piranhas: Eddie is frightened of crossing the stream because of the piranhas.
 * Bruce from Jaws: seen by a boy named Tommy Vicananza in the Derry Canal in 1985.
 * Dracula: resembling Kurt Barlow from Salem's Lot: Dracula appears on a staircase in the Derry Public Library to Ben Hanscom below. The vampire has a mouth filled with Gillette razor blades positioned at odd angles that slash bits of its flesh every time it speaks. The vampire taunts Ben about the deceased Stan Uris as parts of its face and blood are spewed down onto the library patrons below, unbeknownst to anyone but Ben.
 * A Paul Bunyan statue: (referred to as "The Giant"), encountered by Richie outside of town.
 * Tony Tracker: The manager of a trucking depot which had a baseball field behind it during the Losers' childhood, seen by Eddie at the trucking depot in 1985.
 * Greta Bowie: A female classmate of the Losers who died in a car crash a few years after 1958, seen by Eddie at the trucking depot in 1985.
 * Patrick Hockstetter's decomposing corpse: Seen by Eddie at the trucking depot in 1985.
 * Leper Version of Reginald "Belch" Huggins: Seen by Eddie at the trucking depot in 1985. In zombie form later gives Henry Bowers a lift to the Derry Town House to murder the remaining Losers' Club members in 1985.
 * Frankenstein's Monster from I Was A Teenage Frankenstein: when encountering Henry Bowers and his cronies, Victor Criss and Belch Huggins in the sewers under Derry.
 * A Doberman Pinscher: When appearing to Henry Bowers in Juniper Hills Mental Institution. This breed of dog is the animal the guard on duty fears the most, so IT turns into an eight-foot-tall version. In the 1990 film, it was a Rottweiler instead of a Doberman Pinscher.
 * A ghost-moon: While convincing Henry Bowers to do its dirty work.
 * Victor "Vic" Criss: To convince Henry Bowers to help IT.
 * Jimmy Donlin's mother: Dead and eaten, appears to one of the inmates at Juniper Hills.
 * The head of Stan Uris: Full of white feathers inside Mike's fridge. Appears again as a jack-in-the-box when Henry fights Mike in the library. Mike sees Stan's head before it changes to Belch's head, while Henry sees Victor's head.
 * Mrs. Kersh/Witch: from Hansel and Gretel. Beverly Marsh visits her former home and finds a woman named Mrs. Kersh living there. Mrs. Kersh then transforms into the witch, revealing that she is actually IT.
 * Decomposing children's corpses: perceived by Stan Uris as he enters the Standpipe and remembers the tale of kids who drowned in the water tower's reservoir.
 * The deadlights: when Henry Bowers and the Losers encounter IT. This is as close to its truest form as can be explained.
 * Giant Spider: the true physical form of IT on Earth.

Forms of IT in the 2017 film
IT assumes thirteen forms in the 2017 film.


 * Pennywise the Dancing Clown
 * Georgie Denbrough: After claiming the young boy as his victim, IT frequently torments Bill by taking Georgie's form. It did this mainly by running around in a yellow raincoat, but at one point meets him face-to-face in the Denbrough basement with his face deteriorating. Later, while under Neibolt House, It uses Georgie's form again in an attempt to trick Bill into lowering his guard, but the ruse fails and Bill shoots It in the head, forcing It to return to Its Pennywise form.
 * Librarian: One of the librarians turns to stare at Ben ominously while he reads the book detailing the history of Old Derry, appearing closer and closer until a few moments later. The librarian is the only person apart from Ben who is moving. The following moment, a red balloon appears in the place the librarian had been standing.
 * Headless Child: While Ben Hanscom is reading a book detailing the history of Old Derry, he sees a black and white photograph of the aftermath from Kitchener Ironworks explosion, where many children were killed during an Easter Egg hunt. On close examination (possibly provoked by IT), a child severed's head can be seen in a tree. Almost immediately afterward, Ben sees a smoking egg that leads him downstairs to the library basement. When he hears footsteps coming downstairs, he sees the body of a burnt child with no head. The headless child chases him through the maze of shelves, soon after morphing into Pennywise.
 * Judith: Stanley Uris is afraid of a woman in a painting (credited as Judith) in the office of his father, Donald Uris. The woman, depicted in the style of Italian painter, Amedeo Modigliani, is rendered with an elongated face and fingers. This woman left the painting and frightened Stan into leaving the office. The woman later chased swiftly attacked Stan in the sewer, briefly feasting on his face until it was scared off by his friends. The woman's head appeared one last time to frighten Stan but was knocked back a few moments later.
 * Infected Leper: Because Eddie's fear was infections, IT became an uncurable-stage leper. As the leper, IT emits growling noises and creaks open the door as Eddie walks past IT's residence, causing Eddie to be distracted and drop his pills. As he reaches to pick up the last one off of the pavement, the leper takes it and asks if it will "help" him, proceeding to chase Eddie around the corner of the house and into the back yard. The leper later caused Eddie to fall onto a table and break his arm when inside the Neibolt Street house. When IT was attacked by the Losers', IT became a leper once more and vomited on Eddie, causing the latter to kick the former which resulted in IT morphing into Beverly's father.
 * Charred Hands: Mike Hanlon sees the charred hands of his burning parents and other fire victims attempting to escape from behind a padlocked door.
 * Clown: A clown appears on a stage at an event the Loser's Club are near, but no one appears to be interacting with it or acknowledging its existence, and it grins evilly at the Losers when Richie admits he is afraid of clowns, making it very likely that it was a form of IT used to observe the children.
 * Richie Tozier (doll): When Richie look at the coffin and his missing paper with the blood paint "FOUND," he pulls the body bag and sees a doll version of himself with bugs consuming it and closed the coffin until IT came out.
 * Betty Ripsom: A victim of IT, Betty Ripsom's zombified corpse attacks Patrick Hockstetter in the sewers. Her head and torso later appear behind a door in the Neibolt Street house.
 * Eddie Kaspbrak: In the Neibolt Street house, IT appears to Bill and Richie as Eddie's head emerging through an old mattress. He asks them if they "want to play loogie," then spews caustic blood before disappearing back inside.
 * Werewolf: After an iron rod is impaled into IT's head, IT partly develops several werewolf characteristics, such as an elongated mouth and grin, as well as a monstrous hand.
 * Mummy: During the Loser Club's final encounter with IT as children, IT briefly takes the form of what appears to be a mummy wrapped in bandages, which uses them in an attempt to pull Ben into its snapping mouth before being hit with a chain by Bill.
 * Alvin Marsh: While the Losers are fighting off IT, it attempts to scare Beverly by transforming its head into her father's, but she violently jams a rod down its throat in response.

Forms of IT in the 2019 film
IT assumes twenty-three forms in the 2019 film.


 * Pennywise the Dancing Clown
 * Patrick Hockstetter's corpse: Patrick Hockstetter's zombified corpse appears to an adult Henry Bowers from under the latter's bed and hands him a knife.
 * George Denbrough
 * Infected Leper: The leper is shown in an illusion detailing Eddie as a child leaving his mother to be infected by a naked leper breaking free from chains. Later, an adult Eddie encounters the leper, now fully clothed, but forces It back and strangles It until It vomits a black liquid onto him, then disappears. Eddie's ability to harm It in the form of leper causes the Losers to realize that It is bound by the limitations of the form It chooses. The leper's head appears one final time on a giant, Spider-form Pennywise for a very brief period of time.
 * Sonia Kapsbrak
 * Mrs. Kersh: An apparently sweet and gentle elderly woman, who lives in Beverly Marsh's childhood home.
 * The Witch: Mrs. Kersh emerges from a dark hallway in Beverly's house, stomping out as as a disproportionate, grey-skinned, naked Witch-like monster with a mouth visible on its throat and bulging eyes.
 * Robert "Bob" Gray: Soon after the Witch attacks, an adult Beverly sees IT, but instead of Pennywise, It is more human and appears as a man with a large forehead with orange hair, putting clown makeup on as It changes into Pennywise.
 * Paul Bunyan statue: A Paul Bunyan statue with razor-sharp teeth and bats flying out of its mouth terrorizes a young Richie.
 * Adrian Mellon: IT briefly takes the form of a zombified Adrian Mellon to pass Richie a flyer for his own funeral before Pennywise appears atop the Paul Bunyan statue.
