Computer Boy (also known as Charlie) is a character from the Poppy song of the same name, as well as her YouTube videos. He was first referenced in "He loves me not". He is rumored to be the male voice in the song "I'm Poppy". He appears in the music video for "Computer Boy" more prominently, where he's shown to have been transformed from a human person into a computer application.

He made an official website in 2017, where he regularly answered fan questions and put up riddles that were important in his campaign to 'save Poppy'. At one point photos were leaked through his command prompt of Poppy being wheeled out of the TMI headquarters on a gurney by two men that likely represent the colored men.

In an interview with Circa, Poppy stated that her handlers won't allow her to be dating anyone of either gender, and that they took Computer Boy away from her when she fell in love with him.
