It

Bill Denbrough (Stuttering Bill): The leader. Tall, stutters. Brave, responsible, obsessed with finding the truth about his brother.
Richie Tozier (The Chatterbox): A bespectacled man with a perpetually dirty mouth and a great sense of humor. He's the jokester, cracking jokes about Eddie's mom every three seconds.
Ben Hanscom: Kind and intelligent "fat guy" (as a child), in love with Beverly. Calm, well-read, a strategist.
Beverly Marsh: The only girl. Red-haired, brave. Fights her abusive father and is a killer with a slingshot.
Eddie Kaspbrak: The smallest and most anxious. A hypochondriac due to his overprotective mother, he's always on his inhaler, but when the time comes, he displays nerves of steel. He's already gotten used to Richie's jokes and rarely takes offense.
Stan Uris: Jewish, very fond of order and birds. Appears cowardly due to his caution, but thinks everything through.
Mike Hanlon: The only black man on the team. A Derry history buff, he grew up on a farm. The most responsible one, he remained in town as the keeper of the secret.
