Trogg

Shirob was once the third and eldest of the Enchanter Kings, three kings that ruled over the Nameless Zone. The Eldest of The Enchanter Kings, with the most powerful magics, Shirob had accidentally summoned 'The Evil One' (later 'The Dark One'), a demonic being that drove him insane and transformed him into the monstrous Trogg. Incredibly strong and with the power to turn others into beings like him, he disappeared and terrorised the Zone. The other Kings believed Trogg had murdered Shirob until the truth was uncovered.

Tails first met Trogg in The Nameless Zone (STC 16 & 17); believing him a great warrior, the Enchanter Kings summoned Tails to battle Trogg on the Dimension Bridge. Tails won by a fluke and Trogg was expelled to the Land Beyond on the other side of the bridge. Once there, he took command of the goblin hordes. Later, a vengeful Trogg assumed the form of Shirob in order to send a message for help, drawing Tails and his swordsman ally Errol Blackthorn into a trap.

Trogg's final fate came in The Revenge Of Trogg (STC 59-64). Trogg had captured both Enchanter Kings and transformed Errol Blackthorn, who'd gone to rescue them, into a monster. Tails (and accidentally Knuckles) were summoned to stop him, along with Errol's sister Morain, but they were swiftly captured by Trogg's army. Trogg revealed that he intended to transform the other Enchanter Kings into monsters like himself, and to do this he summoned the Dark One. The heroes escaped, stole the black orb from where the Dark One was summoned, and threw it from the Dinemsion Bridge into 'non-existent space' below, causing The Dark one to cease to exist. This reversed the transformations of Errol, the Enchanter Kings, and Shirob himself. With his sanity and form restored Shirob bid Tails and Knuckles farewell.

When Tails was summoned the final time to the Nameless Zone, this time by Morgan, Shirob was shown simply as one of the three Enchanter Kings, and showing no signs of his previous madness as Trogg.
