Creet

Creet was a young human boy who lived on the planet of Malcassairo, waiting to fly to Utopia from Silo 16.

Biography
Creet helped out at the Silo 16 refugee base by helping new refugees find their friends and relatives. He seemed to be an orphan; when asked who he was travelling with, he said it was just him. When Martha Jones asked him what he thought Utopia would be like, he said his mother had said, " The skies are made of diamonds".

He boarded the rocket with many other refugees when the Tenth Doctor and Jack Harkness fixed the system, allowing the ship to take off. Creet said goodbye to Martha before heading for Utopia. (DW: Utopia)

Once there, Creet became a Toclafane. (DW: Last of the Time Lords)

Appearance
When asked his age, he replied, "old enough to work". He appeared to be around 9 or 10 years of age. Creet had long, blonde hair and wore a grubby pull-over with a brown waistcoat. He spoke with a Scottish accent. (DW: Utopia)

Behind The Scenes

 * Creet was portrayed by young Scottish actor John Bell, who was given the opportunity in a Blue Peter competition.
 * David Tennant, Freema Agyeman and John Barrowman stated on the audio commentary for DW: Last of the Time Lords that because of the many times John Bell had to repeat his line, "Im looking for Bilto Toc Shaffe Cane", they had it stuck in their heads and made numerous references to it throughout the commentary. Barrowman even included it in a joke "Mini-Song" about Martha walking around Earth telling stories about the Doctor.
 * Freema Agyeman also stated that upon meeting John Bell she thought he was a girl due to his long hair.
