Beverly Marsh

In the 1990 version, Beverly lives with an abusive father and joins Bill and Ben in the Losers. Ben sends her an anonymous poem, and she thinks it's from Bill. In the sewer battle she hits It with a slingshot of silver earrings. Thirty years later she returns to Derry, helps free her friends from the deadlights and kills the creature with the others. In the end she and Ben marry and are expecting their first child.

In It, Beverly is the target of cruel rumors at school and an abusive father at home. Bill and Ben both fall for her. In the bathroom she sees the sink explode in blood that only she can see. The Losers become her refuge.

During the attack on the Neibolt Street house, Beverly is the one who wounds Pennywise with an iron spike. Weeks later, after she gets free of her father, the creature abducts her. She goes catatonic after seeing It's deadlights but wakes when Ben kisses her. In the final battle, she is the one who drives the pipe into Pennywise's face. Before they part, she has a vision of the group fighting the creature again as adults.
