The Doctor and Ace travel to Maruthea for Bonjaxx's birthday party. Whilst there he encounters old friends and enemies, and has a glimpse of his future.
The trick to getting to Maruthea is apparently not to be there at all, causing you to be so.
Technology
One of Bonjaxx's gifts appears to be the same shape as K9.
Time Lords
The Seventh Doctor asks his future incarnation if they ever repealed the First Law of Time.
Notes
As the Seventh Doctor materializes on Maruthea, another TARDIS is seen dematerialising. Only the leg of the pilot is seen, who says, "What makes you think there's a friend of yours in my TARDIS?" as they kick a small penguin out of the TARDIS. The striped pant leg suggests this is either the Fifth or Sixth Doctor, the latter of which travelled with Frobisher.
The likeness of the "future Doctor" is based on Nicholas Briggs, who portrayed the Doctor in the Audio Visuals series of unlicensed audio dramas; his companion Ria also first appeared in the Audio Visuals.
Two individuals are largely obscured by dialogue balloons. As seen in the colourised version, one is a humanoid figure in a red uniform sitting with Hulk and the other is a man with a grey mustache and beard and carrying a bindle. They are likely Captain Scarlet and Catweazle, the main characters of the British TV shows Captain Scarlet and the Mysterons and Catweazle, respectively.
Captain Britain is seen three times in this comic, each appearance corresponding to his 1970s, 1980s, and 1990s costumes. While they are never seen in the same panel, this could indicate that Captain Britain is attending this party at different points in his timeline, just like the Doctor.
The drunk Meep was told by Shaman Kahn that the Freefall Warriors would be at Maruthea and wants to claim the reward. Shaman Khan was last seen crashing into an asteroid belt, thus losing a race against Big Cat. (COMIC: A Ship Called Sudden Death)
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
