Missy Cooper

Missy Cooper is the fraternal twin sister of Sheldon Cooper, born on February 26, 1980, at a Kmart in Galveston, Texas, and raised in Medford, a fictional small town in East Texas. Unlike her brother, she possesses natural social skills and emotional intelligence, serving as a grounding force in his life. She is the only member of his family to have actively encouraged his work in science was his maternal grandfather, whom he cherished and affectionately called "Pop-Pop"; Missy's role is more that of a sibling who tolerates his quirks while offering blunt honesty. Her appearances in The Big Bang Theory are infrequent but impactful, often during critical moments in Sheldon's life.
