Designers were members of staff at Sonic the Comic who were responsible for the overall look of the comic, from the front cover to the headers on top of features, among others. Clare Gillmore was the first designer, working from Issue 1 to Issue 26, before being replaced by Timothy Read. Gary Knight co-designed with Read one issue later and had completely taken over by Issue 29. It would seem that Knight held this position until the very last issue, but the Issue 223 final roll call states that Charles Wrigley, Jason McEvoy, Paul Shubrook and Steve Cook also had designing credits in past issues.
In Sonic the Comic Online, co-editor Mike Corker is reponsible for aspects of the comic's design and has overseen several major redesigns. As an online comic, Corker also has the responsibility of uploading the individual comics to each issue.
