Film: Since It takes on different forms depending on the target at hand, each member of the Losers' Club faces a different kind of monster:
- Bill sees the rotting ghost of his brother, Georgie, who disappears at the beginning of the film.
- Eddie, a hypochondriac, sees a disease-ridden leper at 29 Neibolt Street.
- Richie has a fear of clowns, so Pennywise manifests with a bunch of clowns in one of the rooms of the Neibolt house.
- Ben, who seems to be especially disturbed by Derry's Easter explosion disaster in the early 20th century, gets chased down by a youngster whose head has been blown clean off.
- Beverly, who's terrified of becoming a woman because of what it might mean for her abusive father, gets drenched in blood.
- Mike, who had to watch his parents die during a terrible house fire, sees frantically burning hands as they try to reach around a locked door.
- Stan is very creeped out by a painting of a deformed woman in his father's office. She comes to life, straight out of the painting, to capture him.
Novel: Just like the movie, It manifests in different ways for each of the Losers.
- Bill also sees the ghost of his brother.
- Richie, in the books, is scared of werewolf movies. This is one of It's most iconic forms in the novels: on more than one occasion, It becomes a werewolf in a letterman jacket.
- Instead of seeing crispy children with missing parts, Ben sees a mummy.
- Beverly sees a fountain of blood, just like in the movie.
- Mike witnesses another particularly graphic form of the monster. During a gripping sequence, It transforms into a gigantic bird and tries to eat Mike alive. He narrowly escapes.
- Instead of the menacing lady in the painting, Stan sees two drowned boys.
