David Gibbon was a "Game Guru" for Sonic the Comic, being a prominent face within the Review Zone and Q Zone. Gibbon compiled the vast majority of Q Zone entries, often only stepping aside for Vincent Low for the "Sonic Solved" series. Gibbon also provided the majority of reviews, although he would be phased out in favour of Chris Jones for later editions.
