Creet

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)

Creet's Legacy
During The Year That Never Was, Martha Jones, Thomas Milligan, and Professor Alison Docherty set a trap for one Toclafane by using a powerful electric current to bring it down. They opened the casing up to find a distorted human-like face, surrounded by machinery. When the Toclafane recognized Martha and talked about the skies being 'made of diamonds', she remembered Creet telling her this about Utopia. This confirmed to her what she suspected about the Toclafane and their origins. She confirmed that the Toclafane were the last of the Humans, from far in the future. Alison questioned why they did not cancel themselves out as they had murdered their own ancestors, to which Martha realized and pointed out about the Paradox machine that allowed the Grandfather Paradox. Thomas questioned "we are the same species, why do you kill so many of us?" The Toclafane responded "Because it is fun!" in a giddy tone and laughed in his mechanically altered voice. Horrified and disgusted, Tom shot him dead. However, when time reverted with the destruction of the Paradox machine, it is likely that his fate was altered and was back alive as a sphere at the end of the universe, without knowing what had happened. Then he would die out, along with the rest of the Toclafane species, thus bringing an end to the Human race. (DW: Last of the Time Lords)
