Author's summary: The Doctor has a regeneration relapse.
Characters/Pairings: Ninth Doctor, Eighth Doctor, Seventh Doctor, Brigadier, Sixth Doctor, Jack, Fifth Doctor, Fourth Doctor
Warnings: nothing more than a little bit of Jackish innuendo
Recced because: It has the most amusing summing up of the end of Doomsday ever:
“Alas, Rose. Not dead, yet parted from me by the gulf of the infinite void, trapped in a parallel Universe with her mother, her parallel not-dead father, her ex-boyfriend, and a baby.”
But seriously, this fic never fails to make me giggle. It starts out with the Doctor waking up shortly after The Runaway Bride only to find that he's back to being Christopher Eccleston again. Not only that, but whenever he loses consciousness he goes back an incarnation. (The above quote comes from the Sixth Doctor) And he's just developed an unfortunate tendency to faint...
It's not a perfect fic, I'll admit. LilacFree refers to the various incarnation by their number (Nine, Eight, Seven and so on) which can be jarring at first. But it's a very fun multi-Doctor romp that nearly everyone should be able to enjoy.
