Although there has not yet been a Black Knight adaptation in Sonic the Comic Online, several STC characters appear in various guises (Knuckles the Echidna, Shadow the Hedgehog, Blaze the Cat, Amy Rose, Tails, Jet the Hawk and Sonic himself), although as their SEGA characters. The only in-comic reference is on the cover of the Hallowe'en Special, where the Werehog can be seen holding Caliburn. No entry in the Review Zone has yet been made for this title.
In Issue 250, a special Black Knight Zone feature celebrated the Humes that were able to get their artwork published in the game. The article, including famous images from Sonic the Hedgehog CD, Sonic Adventure and Sonic the Hedgehog 3, featured interviews from artists Adamis, Jin Chan Yum Wai and Zak Simmonds-Hurn.
