Timeslip (comic story)

Timeslip is a Doctor Who Weekly comic story featuring the Fourth Doctor and K9 Mark II. It is notable for introducing the concept of retro-regeneration, depicting the first time a Time Lord has reverted back to their previous incarnations, and the first instance the Doctor ever retro-regenerated.

Summary
The Doctor and K9 drift into contact with a deep space entity which feeds on time itself. As time begins to move backwards, K9 reverts to the components from which he was made and eventually to a pool of metal. Meanwhile, the Doctor moves back through his third, second and finally his first incarnation at the point where the Doctor first threw the switch to bring life to his TARDIS.

As the power reversal switches the power off, the entity weakens and time moves forward enough to throw the switch on, then back off, then on and so on. Each time the switch is changed, the entity experiences indigestion and eventually weakens. As time rolls forward once again, all that is left of the entity is a puddle on the TARDIS floor.
