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.
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.
- The Doctor expresses a wish that he could contact Romana II.
- This story was announced in the previous issue of Doctor Who Weekly as Time Trap.
- This is the first comic strip story to feature an incarnation of the Doctor other than the then-current fourth incarnation, and the first appearance in the comic strip of K9.
- This marked the first DWM appearance of the First Doctor, Second Doctor and Third Doctor. While the First and Fourth Doctors drive the story, the Second and Third appear only transitionally.
- This was the first multi-Doctor story in any medium since the television story The Three Doctors in 1973.
- The full-page regression of the Doctor (which relied heavily on photo-reference of stock photos) through his earlier selves was also used as the basis of a colouring competition in DWM 24.
- The images of the various Doctors (and enemies) appear to have been based on promotional images that were around at the time.
