Beverly Marsh is one of the seven members of The Losers' Club. She is sexually abused by her father, Alvin Marsh. She is best friends with Bill Denbrough, Richie Tozier, Eddie Kaspbrak, Mike Hanlon, Stan Uris, and Ben Hanscom. Beverly also has a crush on Bill Denbrough.
In the book she’s described as a really pretty girl with auburn hair that reaches her shoulder blades, lovely gray-green eyes and milky skin with a spray of freckles. In the 1990 mini-series, she has chest-length brunette hair and in the 2017 film adaption, she has red hair.
