Well, Twelve's time has just ended, and since the last two threads (special shout-out to Green Lantern for the second thread), the mysterious circumstances under which the Sixth Doctor regenerated into the Seventh have finally been unveiled thanks to Big Finish, so you could say we have at last, a more complete set of regeneration stories for the 50 years since the concept was introduced. So now, after 2017, and on the eve of the eleventh series of NuWho, what's your favourite regeneration story? I predict that Caves of Androzani will once again dominate the polls, but at least its a rolicking good story. In any case, rank & rate! *I also wasn't sure if I should include Day of the Doctor because... well, I don't really consider the Warrior a real Doctor. Not that he's not, but the incarnation didn't headline the show, and he was scorned by the Doctor's future selves with a reason. He's an incarnation of him, but until Eleven's near end, we didn't even know he existed. Heck, he was actually introduced in the third to last of Matt Smith's episodes. Plus, its not remembered for being a regeneration story, either. So, I'm leaving this one out, but you could always include it in your lists.
