Elizabeth "Betty" Cooper is a main character on The CW's Riverdale. She is portrayed by Lili Reinhart.

Betty was a student at Riverdale High School and longtime best friend of Archie Andrews, Jughead Jones, Kevin Keller and Veronica Lodge. She is also a former River Vixen as well as an editor for the Register, with her mother. Betty is the youngest sibling to her sister, Polly and older half-brother, Charles Smith. Most recently, Betty has followed in her mother's footsteps of joining the Southside Serpents, alongside her then boyfriend, Jughead, making her the Serpent Queen to his King.

She is very cheerful, full of energy, a bit childish and overall pretty fun to be around! She loves her fans and every single one is special for her! Well... That's her public image. Off the scene she is completely different woman, almost polar opposite of the cheery energetic person her fans know and love.
