Changes (comic story)

 was a Sixth Doctor comic strip that was published in Doctor Who Magazine. It was significant for showing many sections of the Doctor's TARDIS other than the corridors commonly seen on television.

This story also saw the appearance of another shapeshifter aboard the TARDIS: the Kymbra Chimera. This Chimera took on the appearance of both the Sixth Doctor and Peri Brown.

Plot
Peri and Frobisher are rummaging through a storage room in the TARDIS. Peri is so much taken aback by the cultural treasures she discovers that she doesn't pay attention when the Sixth Doctor reports that there is an intruder aboard the TARDIS. Peri and Frobisher decide to explore the TARDIS some more, while the Doctor investigates the intruder. The Doctor discovers a Swuffle he brought aboard was in fact a shapeshifer, a Kymbra Chimera. The shifter changes to the form of Peri, but Frobisher quickly spots the difference. The chimera and Frobisher fight as the Doctor discovers a way to suck the intruder out the TARDIS. He does so in the nick of time.

Characters

 * Peri Brown
 * Kymbra Chimera

The Doctor

 * The Sixth Doctor possesses portraits of himself by Michelangelo and Vincent van Gogh. Which incarnations of the Doctor they depict is left unrevealed.

Energy beings

 * The Doctor mentions the Mandragora Helix from The Masque of Mandragora.

Literature

 * Peri finds a folio of a play called Mischief Night, or As You Please, which she surmises may be a lost play by William Shakespeare.

TARDIS

 * Other items visible in the TARDIS storage room include a National Geographic Magazine, assorted toys, a globe, a map of Barsoom, a Dalek construction kit, and a 78 rpm record by Bill Haley.
 * When the Doctor and Frobisher walk through the TARDIS interior, Bessie is seen stored in a darkened room. Clothes the the Fourth and Fifth Doctors wore are also shown on stands in another chamber.
 * The TARDIS has a "Memory Vaults" area that recreates places the ship has visited.
 * There is also a populated TARDIS Zoo, which the Doctor describes as a "way station" where he keeps endangered animals, often saving them from extinction.

Continuity

 * Peri has the same hairstyle and clothing similar to what she wears in The Mysterious Planet.
 * The TARDIS' state of temporal grace, which renders weapons useless, does not function when the ship is in "normal space". (This is a possible attempt to rectify continuity issues created by several occasions on which weapons are shown being fired within the TARDIS.)
 * The Doctor returns to the secondary control room last seen in The Robots of Death. The room includes a tea dispenser.
 * The Doctor mentions the Mandragora Helix, which first appeared in The Masque of Mandragora.
