A remake/remodel challenge that elicited a lot of response back in the day was for The Doctor. Specifically the final one. The instructions were quite simple.
A Time Lord can regenerate twelve times before dying. Thirteen incarnations in all.
Design the thirteenth incarnation of the Doctor.
Brainstorming the words “thirteen” and “doctor”, two images kept coming to mind (once I finally banished DC’s “Dr. Thirteen”). The first is a 13-year-old (riffing on the trend until just now for younger and younger actors in the role). The second is the doctor known as “Thirteen” from House, M.D.. Which of these is the Doctor and which is the Doctor’s companion is an exercise left to the reader.
