Baltazar
Baltazar was a space pirate who had once been imprisoned on the prison planet Volag-Noc.
Biography
Baltazar was determined to compress the planet Earth into diamond, which would have killed off life on the planet. The Tenth Doctor and Martha Jones stopped him. Later, Baltazar searched for the lost ship, the Infinite, via its data chips, and used the Tenth Doctor to track it down. He had a metal bird pet called Caw.
Baltazar was called "Corsair-King of Triton ", although it is unknown whether this means that he had actually seized power on Triton or was merely a pirate who operated near it. The Tenth Doctor seemed to favour the former when he referred to him as "The greatest despot that ever, ever lived," although this could have been the Tenth Doctor's penchant for hyperbole at work.
Baltazar was also famous for having built his own warship, which he considered the finest ever built, by hand over "countless decades", an accomplishment that The Tenth Doctor considered "really cool" moments before he destroyed it with a spoon.
The Tenth Doctor called him the "Scourge of the Galaxy". Baltazar was notable for having a sense of humour (rare among the Doctor's opponents) and poked fun at Martha and laughed while watching the Doctor awkwardly trying to pilot Caw's offspring, Squawk. (DW: The Infinite Quest)
