"The Unknown Inspector" refers to the mysterious individual who appeared at the end of the episode "The Alias of the Inspector" and in the webisode "The Twilight of the Inspector" and the 50th anniversary special, "The Night of the Inspector". He is played by American actor William Hurt.
"The Alias of the Inspector"
After the apparent destruction of the Supreme Counter-Intelligence, the Eleventh Inspector and Geneva return to the BOOTH and find a shadowy figure inside. He opens the door and tells the Inspector to follow him somewhere. The Inspector obeys him without saying a word as the stranger pulls out a revolver. Geneva asks the Inspector who this man is and why he must follow him, but he only answers, "I can't do anything against him. He is me!"
As the BOOTH fades away, the words appear on screen "With WILLIAM HURT Playing THE INSPECTOR!"
"The Twilight of the Inspector"
The Unknown Inspector in mid-transformation
In a surprise return appearance of Steve Carrel, the Eighth Inspector goes undercover during the Time Wave and adopts the identity of the Unknown Inspector with the special assistance of the Teman Mothers, who use their mystic water to transform him in a different version of the standard Infinity Knight metamorphosis.
Fan Theories
Waiting for the 50th anniversary special for an explanation of the character, fans tried to guess who this Inspector was and where he fit in the show's timeline. Some popular theories include him being the Indictor or the Anti-Inspector, the fourteenth incarnation of the Inspector, a young First Inspector, or a transitional form between the Tenth and Eleventh Inspectors. A BTV-approved graphic novel from CCC Publications refers to this character as "The Rogue", though its canonicity is currently unconfirmed.
