Bluebird

Avril Lark works at a quiet bookstore in National City, but unbeknownst to many, she is also a member of the Super Friends. With her power of flight and communicating with birds, Avril (as the superhero Bluebird) helps Supergirl, Guardian, Dreamer, Winn, J'onn, Lena, Alex, and the others to save National City. IMPORTANT: This starts right after season 2 ends, and goes until the show ends.
