The Doctor is on the planet Adeki, trying to fish, when he comes upon an old city of the Adekians. It is populated with metamorphic aliens. On meeting him, they take the shapes of his former companions (most of whom are dead), but then take the form of his previous selves.
The Gwanzulum feed off life energy in order to shape change.
Notes
The inclusion of Peri implies that the Doctor still thinks she is dead. (As was suggested in TV: Mindwarp, though this was shown to be false in The Ultimate Foe) It is possible he recalls the events of Peri and the Piscon Paradox, where it is revealed that a version of Peri did die.
The Gwanzulum shapeshifters were an idea by John Freeman that Richard Starkings decided to use across almost every Marvel UK comic at the same time.
The story was later reprinted in DWCC 14 with additional colours.
This was artist Lee Sullivan's first Doctor Who comic.
