Creet
From Tardis Wiki, the free Doctor Who reference
Creet was a young Human boy who grew up on the planet of Malcassairo, waiting to fly to Utopia. He helped out at the refugee base. (DW: Utopia)
Once there, as with all the Humans, he became a Toclafane. A shared memory resulted in one Toclafane recalling Creet's ideas of Utopia. (DW: Last of the Time Lords)
