Ninth Drax

The Ninth Drax, under the pseudonym of "Galdron Cabot", pretended to be a criminal-turned-businessman who rivaled Charles Kirkland. At this point, Drax's memories were starting to dim due to age.

In reality, the Ninth Drax was plotting with ten of his incarnations to make the Fourth Doctor raid the most secure safe-house in history in order to retrieve a Blinovitch Limitation Effect limiter.

After the Doctor and Romana discovered their plan, they went to the Rutan's Tendril, where they knew the four Draxes would be, and called inspector Fleur McCormick to arrest them. However, by the time they realised that Drax must have known he would have been arrested over different incarnations, they realised the truth about McCormick and her men, and by the time they returned all of Drax's incarnations had escaped in their TARDIS.
