Josiah W. Dogbolter

Half-man, half-frog, Josiah W. Dogbolter was a ruthless capitalist of mysterious origins and the owner of Intra-Venus, Inc.. On a number of occasions, he employed quirky mercenaries in attempts to capture the Doctor's TARDIS, which he saw as a way to make even more money.

Biography
As head of Intra-Venus, he actually owned the planets Venus, Mars and Jupiter and other worlds, including the mining world Celeste. A loyal robot named Hob assisted him in his financial decisions. Mistaking the Fifth Doctor and his companion Gus for rebel leaders, he learned of the TARDIS. Thinking that "time equals money" and therefore a time machine would create money for him, hehired the Moderator to locate it for him. The Moderator fatally shot Gus, despite which the Doctor rescued the Moderator, ensuring that he got on life support. Dogbolter ensured that Hob disconnected the Moderator from life support. He died. (DWM: The Moderator)

Dogbolter offered a quarter of a million mazumas as a reward for the Sixth Doctor. Frobisher intended to collect the money, but instead befriended the Doctor. They stole the money from Dogbolter's estate and then escaped. (DWM: The Shape Shifter)

Josiah was searching for "the something", an object that if sold, could disrupt the economic stability on one of his planets. He bribed the police officer, Chandler, to work for him. In a demonstration to Frobisher, Josiah killed his henchman, Elgar. He found "the something" wase a microchip. Upon activation, the microchip delivered a joke to the worker's screen. This gave them imagination, destroying the economy. (BFA: The Maltese Penguin)

Dogbolter later developed the Dogbolter Temporal Rocket, promising unlimited potential for personal time travel to his shareholders. He employed Death's Head to hunt the Seventh Doctor through time using the prototype, but planned to destroy both with a nuclear weapon built into the device. Working together, Death's Head and the Doctor removed the bomb and left it on the roof of Intra-Venus HQ. Dogbolter and Hob fled to the secure sub-basement. Held up in the elevator, Dogbolter found his passcard with seconds to spare (DH: Time Bomb!) but both were caught in the blast. Hob refused any suggestion that Dogbolter had perished in the explosion. (DH: Time Bomb!)
