Changes (comic story)

 was a Sixth Doctor comic strip published in Doctor Who Magazine. It was significant for showing many parts of the Doctor's TARDIS other than the control room and corridors usually seen on television.

This story also included 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 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 shapeshifter, a Kymbra Chimera. The shifter changes to the form of Peri, but Frobisher quickly spots the difference: Peri's clothes and necklace are fused into "her" flesh, as the Chimera is unable to duplicate clothing. 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.
