Polly Cooper is Betty’s older sister who was introduced in Little Archie in the 1960s as teenagers. For years, she was not canonical characters. However, by the 1990s, Archie Comics began to tie Little Archie into the main continuity with characters that originally only appeared in Little Archie. She has strawberry-blonde hair, is currently in her twenties, but is significantly older than Betty. Polly still affectionately calls Betty “baby sister” on occasion. Polly works as a news reporter in San Francisco.
