Changes (comic story)

Summary
As Peri and Frobisher are rummaging around the Doctor's objects, including a crystal, the Doctor walks in, and warns them that the TARDIS has been invaded, and suggests they stay where they are. The Doctor leaves with the crystal before Frobisher can tell him that Frobisher has his powers back. Peri and Frobisher soon after leave the room, and go to search for the invader.

The Doctor is searching around the TARDIS' jungle, while a creature behind him watches and slowly morphs into the Doctor's form.

Peri and Frobisher head towards the memory vaults, where the memories of all the pictures the TARDIS have been are kept. Peri heads inside, and is instantly transported into an alien environment. She runs around before colliding into the Doctor, actually the invader.

Frobisher finds the Doctor and explains what happened to Peri. They both head through a shortcut of hovering discs, to find Peri.

Behind Peri the Doctor morphs into the invader, and reaches to grab her. Frobisher and the Doctor find the TARDIS zoo, where the Doctor has kept endangered animals in synthetic habitats until he finds hospitable planets for them to live. The Doctor shows Frobisher one of the canisters, which contained a Swuffle, which is now broken from the inside. The Doctor explained that the invader disguised itself as a Swuffle to get on board, when it was really a Kymbra Chimera, a primitive form of a Whifferdil, which drains energies from machines, in this case the TARDIS.

As they walk on, the Doctor notices things he hasn't before, thinking that the TARDIS is getting bigger. Walking into the Secondary control room, they see two Peris. Frobisher picks the one on the left as the fake, as the jewellery is fused into the flesh. Agitated, the fake Peri shoots an energy blast at the Doctor. As Frobisher changes and attacks the fake, while the Doctor moves to Peri and activates the disposal wheel. Just as Frobisher is being beaten, the fake is pulled out of the TARDIS by a vortex, which shuts down after the creature is gone.

The problem over, the Doctor offers tea.
