Oh no, you have to make all 14 plus all the secondary characters!
I agree about the perception of the first Doctor. That is why he is so hard to define. Like you said, he is what the Doctor should be.
Maybe something like I MADE IT THIS FAR that allows him to circumvent an attack once per game to acknowledge his longevity.
Or you could have the Companions boost or defend him. That guy is tough.
Love the Susan power.
I really like the other designs. Well done. If Manipulate is too much, I would consider making it a Move only power, no Attacking. I was considering something like this for Judge Anderson at one point.
The third Doctor looks perfect.
Nice work on the Brigadier. He was around forever.
