Computer Boy 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 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'. In an interview with Circa, Poppy stated that her handlers won't allow her to be dating anyone of any gender, and that they took Computer Boy away from her when she fell in love with him. Poppy's and Computer Boy's relationship status is unknown after release of Software Upgrade.
