Character Name: The Master
Canon: Doctor Who
Age: Who even knows. Centuries at the very least, and possibly more.
History: http://tardis.wikia.com/wiki/The_MasterCanon Point: Shortly after "Frontier in Space"
Personality: To put it mildly, The Master is not at all a nice person. So much so, in fact, that calling him evil, sick, or twisted is all but guaranteed to get a "thank you" out of him. However, he is, at the very least, willing to be polite. In fact, throughout the entirety of this particular incarnation he serves more or less as the Doctor's evil counterpart - he's brilliant, prone to wandering the galaxy, good at coming up with various technical devices... and also a man who has something of tendency to conquer worlds and peoples, if given half a chance.
Special Powers/Abilities: Hypnotism, telepathy, time senses, various non-human biology (two hearts, increased resistance to heat and cold, immunity to electric shocks that would be fatal to humans, and senses better than human average.) He would also be possessed of the ability to regenerate and so escape death in a pinch, but his current form is the last of his natural regenerative cycle.
