Winning Designs was an article in 1987's DWM 131. It concluded an interactive event begun in DWM 108 and furthered in DWM 113, wherein which readers were first invited to submit their own fan-casting for a new Doctor, companion and antagonist (as the Doctor Who Casting Competition), and, in the second part, to submit sketches for the costume design of the winning entries of the first part (as the Doctor Who Design Competition).
The article also contained an overview of a plot suggested by Acord and Morain for the characters, wherein which the Master would first be confronted in disguise by the Doctor and his companion, Maggie, while posing as the designer of a new space-themed ride for an Americanamusement park. It would transpire that the "ride" was actually a teleporter with which the Master planned to bring a large workforce of aliens to Earth to help him build a device meant to destroy the planet. The Doctor would later discover that the Master had neglected to warn his "allies" that their own planet would likely also be destroyed by the machine.
According to one account, the Master had the appearance of Roger Delgado while on Gallifrey. According to another, he had Anthony Ainley's likeness. According to another one, the one with James Dreyfus's appearance was the incarnation who ran away from Gallifrey.
While fighting to extend his life at the end of his regeneration cycle, many bodies were possessed by the Beevers incarnation, but all kept somehow reverting to his real being until he finally regenerated into the MacQueen one. Hence, these sections cannot be strictly chronological
