Re: How would you make "the Doctor"?
The Doctor is not a character at all. He is the deus ex machina, and the show is really more about the companions and the events. When Dr. Who was originally launched, it was to be a teaching show about history. Obviously it has changed a great deal. However, The Doctor is still "just a guide" through the events of the show, until the need arises that the problem is resolved. He then resolves it in his wonderfully Dr. Who way. But to try to focus on him as a character is a fun exercise, but ultimately he would never be played by a player. He would always be the GM's personal NPC in a Dr. Who campaign if for no other reason than the fact he always wins, and that is why all the bad guys fear him, he is the GM.
Now that said, I think Derek nailed the character build! Well done! And repped!
