Hey! I dig your Dr. Who customs here. I really like your 11th design and your Sonic Screwdriver. Question on that -- if the 11th regenerates, does that mean the 12th doesn't get the Screwdriver? Or are you not planning on in-game regeneration? The "guessing game" with Timey-Wimey looks fun. (I guess you'll always be sure of OM2!)
My only quibble with the 11th wording is that I associate "Timey-Wimey" with Tennant, although I'm sure Smith said it a lot too.
"Companion" is a good power to reuse for all your, well, companions.
I've shamelessly adapted a number of others' Dr. Who designs, you can see them
here if you are interested.
Looking forward to more stuff!
