Starlight, also known as Annie January, is a central character in the popular Amazon Prime series "The Boys." Played by actress Erin Moriarty, Starlight is a young superhero with the power to manipulate light and electricity. Unlike other more seasoned and jaded heroes, Starlight begins the series as a naive and idealistic figure who is horrified by the darker, more morally bankrupt aspects of the superhero world. Despite her youthful innocence, however, Starlight is also courageous and determined, and she learns and grows throughout the series as she faces the harsh realities of the world she has joined.
