My eleventh incarnation. TARDIS attacked by Draconians, ended up crash-landing on a desolate little planet with only 1% of land above sea level. Regenerated due to my injuries, ironically into a face that would have come in handy on the pleasure planets in the Eye of Orion. New good looks totally wasted on the local sapients, but at least they proved useful as a workforce, mining materials from the sea bed with which I was finally able to mend my TARDIS. 200 years, that took. Never want to see another Porg as long as I live, unless I run low on supplies. They taste like chicken.
My ninth incarnation. A gentleman: suave and polite, but quick to anger. I began to once again split my attention across multiple schemes, but this time with a singular goal: to infiltrate the inner sanctum of the High Council of Gallifrey, and access the full content of The Matrix. With knowledge of all time and space at my fingertips, dominion over the universe itself would be assurred!
My seventh incarnation; good-humoured, urbane, erudite - and utterly ruthless. As much at ease with pulling the trigger myself as with sending an army of Ogrons to crush my enemies. I was unusually focussed, too - one scheme at a time, with all my attention dedicated to a single goal - which is possibly why this incarnation lasted several hundred years longer than any other, before or since. Remember: distractions can kill.
Seventh incarnation. Quiet, reserved, and very dangerous. Charm became a big part of my arsenal, as did hypnotism. I also flirted with an artistic side I never knew I had, and thus far have never had again.
Sixth incarnation, and the first time I went by the title 'Missy'. A master (ha!) strategist and schemer, I spent a great deal of time and energy setting up numerous machinations that extended well past my later incarnations. Alliance with the Nestene Consciousness? Me. First tentative negotiations with the Toclafane and Daleks? Me. Even managed to re-infiltrate Gallifrey in order to gain information on the Matrix, for possible future use. It's amazing how trusting a bunch of old white Timelords can be of a fetching female face.
