Spoilers are precisely defined here. Rules vary by the story's medium. Info from television stories can't be added here until after the top or bottom of the hour, British time, closest to the end credits roll on BBC One. Therefore, fans in the Americas who are sensitive to spoilers should avoid Tardis on Sundays until they've seen the episode.
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.
