Shirob is the eldest and most powerful of the three Enchanter Kings of the Nameless Zone and is also the only one to be named in Sonic the Comic. The senior fox often dabbled in magic and, one night, accidentally contacted The Dark One, the experience driving him insane and turning him into the evil Trogg.
As Trogg, Shirob unsuccessful attempted to invade his home on a number of occasions. The berzerker reverted back to his fox form briefly, sending a message through the Magic Crystal of Communication that tricked the other Kings into sending Tails to rescue Shirob. The fox kept up this act, allowing Tails and Errol Blackthorn to rescue him from being chained to a rock and a Pit Beast's supper. Tails' later destruction of the Dark Orb that powered the Dark One ment that Trogg would eventually turn back into Shirob. After this, Shirob continued his old life as a king, not particularly standing out from his fellow rulers.
