Henry Bowers...

Henry Bowers' gang, also known as "The Bowers Gang," is the main group of human antagonists in Stephen King's novel "IT" and its film adaptations. They are characterized as the bullies of the Losers' Club, operating with a violent and impulsive lifestyle in the town of Derry. Henry Bowers: The psychopathic and sadistic leader, motivated by the hatred inherited from his abusive father. He is the one who makes the decisions and directs the physical violence against the protagonists.
Victor "Vic" Criss: Considered the most intelligent or "conscious" member of the group; he sometimes shows slight reservations about Henry's extreme cruelty, although he ends up following him out of fear or loyalty.
Reginald "Belch" Huggins: The group's enforcer, known for his large size and physical strength. His nickname ("Burp") comes from his ability to burp at will.
Patrick Hockstetter: A disturbing sociopath whom even Henry finds unsettling. In the novel, he has pyromaniac and murderous tendencies (including against animals). He was omitted from the 1990 miniseries but reappeared in the 2017 films.
