SEGA has revealed via their Sonic twitter account that they will be releasing a Sonic Superstars prologue web comic. This comic, called "Fang's Big Break," will star Fang and cover how the mischief on the North Star Islands got started. The comic will be written by Ian Flynn, with art by Evan Stanley and colors by Min Ho Kim.
According to Stanley, the comic will be released in three weekly four page drops, for a total of 12 pages. The first pages will release sometime early next week. These weekly releases will essentially replace the Fast Friends Forever comics for a few weeks, which are now set to return on October 23, according to SEGA's announcement tweet.
