In The Time of the Doctor, the Doctor says that he has a "new regeneration cycle". Does this mean he has another set of 12 regenerations, or just the one?
Probably! But technically nothing explicit was promised.
The general assumption is that he was given 12 new regenerations to play with (minus one now), but Moffat is well known for pulling "technically I never actually said" in order to justify his plot twists, so I wouldn't say it's an absolute certainty: "A whole new regeneration cycle" could conceivably just mean the one regeneration into Capaldi, really.
"A whole new regeneration cycle" implies that he got at least a full 12-pack, if we assume that it plays by the same rules as the old cycle did.
But assumptions like that can be dangerous where this series is concerned. It's possible that it might be a whole new kind of regeneration cycle, and thus it could play by different rules. Even if it still plays by the old rules, they've introduced so many ways around the limit just in NuWho alone that when the time comes, they can just pick another method or even reuse this one. Another thing NuWho introduced is the ability to use regeneration energy for things other than regeneration itself, so we can't even assume that there will be another 12 Doctors before he runs out again, even if he got a full and standard cycle. In short, we know nothing.
Moffat himself said that The Doctor can regenerate as many times as he wants, and as far as the meta-story is concerned, this is true. As long as it makes sense for the BBC to keep producing the series, they will write in as many ways around the limits as they need to. So while the limit may sometimes have meaning within the context of the story itself, I'm not sure it should be treated as meaningful outside the plot.
Personally if they stick to the same number as the old regeneration cycle, he would have 11 regenerations left... According to what Matt Smith's doctor said was that he was reset... meaning to me that this meant that he was the first doctor in the new regeneration cycle... So when he regenerates that would put Capaldi as the 2nd Doctor in the new regeneration cycle.
As far as Moffat saying that The Doctor can regenerate as many times as he wants, that's only true if they allow him to keep getting more regenerations... And in truth there are ways to bypass the limitation of regenerating as well. If you know the older Doctor Who stories, it's said that Rassilon is truly immortal so he has no need for regenerating...
Apparently, The Doctor doesn't know. In Series 8 "Kill The Moon" he stated he wasn't sure if he'd regenerate "forever" if the astronauts kept shooting him. Can't find the exact quote.
I know it's an old question with an already accepted answer, but it's worth noting this new information...or lack of it, if you will.
It is a whole new regeneration cycle meaning he can regenerate 12 more times. If you remember when the TARDIS was in the human body, she said that "she has 30 desktop of the TARDIS" and when the doctor claimed "it has only been changed a dozen times" she said "so far, yes" which could mean that more regeneration are to come.
When the 10th has his hand cut off in the 2005's Christmas Special what does he say? "I'm still within the first 15 hours of my regeneration cycle". So, when the 11th mentions "A whole new regeneration cycle" he might be referring to a single regeneration.
At this point, everything is possible: single regeneration only, new set of 12 regenerations, unlimited regenerations, other number somehow... Nothing got written in stone. And even if it was, come the need they'd find a new way to extend that number.
I think we'll have to wait for the series for some development on that matter. What we know is that there will be new doctors as long as it is proffitable, so we need not to worry. Yet, wish we knew the specific details.
Come on now, he will regenerate as long as the franchise is viable :)
As for the 'new set of lives' This new set of regenerations (judging by the first story) will be the politically correct set. You will see women (very very soon) playing the doctor not too mention every colour of the rainbow. And possibly shock horror an American in the role (all depends 'where' the viewing figures are). And why not! ..to the future horrah
The precedent set in the classic series, when the Master was given a new set of regenerations, was just that - an entirely new set.
The young Matt Smith that appears just before Capaldi does not appear to be a "new" doctor, so the logical conclusion is that the Doctor has another 12 regenerations ahead of him.
We don't know. The writers intend for it to be unknown. Probably at least one more.
In Kill the Moon, the Doctor says he doesn't know how many times he may regenerate, and that he could very well regenerate forever.
You'll have to spend a lot of time shooting me because I will keep on regenerating. In fact, I'm not entirely sure that I won't keep on regenerating for ever.
And in Hell Bent, (the second most recent episode at the time of this answer,) Rassilon doesn't know, but implies the Doctor will regenerate at least once more. When he's about to kill the Doctor, he says,
How many regenerations did we grant you? I've got all night.
The writers were clearly very intentional about establishing that the Doctor has an unknown number of regenerations.
The show will never again have to deal with the problem of the Doctor running out of regenerations unless a future writer wants to make another story out of it. But in any case, we can be certain that the Doctor will never run out of regenerations for as long as the show continues.
He got at least one more, and probably a full set.
As of Series 11, Twelve (Peter Capaldi) has regenerated into Thirteen (Jodie Whittaker). During the final scene of Series 10, Twelve is rather ambivalent about whether he wants to regenerate at all, but at no point does he mention running out of regenerations. Thirteen also has not discussed it during Series 11, and out of universe statements by new showrunner Chris Chibnall have repeatedly emphasized the importance of accessibility to new viewers. Series 11 has heavily focused on introducing new characters and settings rather than returning to past continuity, so it's unlikely that they will bring up the "number of regenerations" issue any time soon.
So in Time of The Doctor, Smith said that 10 aka Tennant was having vanity issues so he regenerated twice. I see the first as healing himself since he got shot by a dalek. And in Night of The Doctor, McGann was dying. The Sisterhood of Khan triggered a regeneration. They also said timelord science was advanced. And right before McGann changes he says physician heal thy self. So I see the War Doctor as Doctor 8.5 and the 8th Doctor as Doctor 8.0. So really Capaldi could be the last doctor, or the new first doctor of a new regeneration cycle. I myself believe that Capaldi being old means a whole new cycle and it will keep the series going on for a few more decades. Probably by 75th Anniversary or 100th Anniversary this will all be explained. Or it will all end with Capaldi.
I think Peter Capaldi is the first the new regeneration cycle Matt Smith was the 12th and final doctor if not counting John Hurt he will be still considered the eleventh doctor Peter Capaldi stays the 12th doctor so he has one more regeneration left or dies in the 8th series after the master returns
A regeneration is when you take a new form, right? The doctor had 12 regenerations. When he was "born" he didn't regenerate into the 1st doctor, which means 1st reincarnation- 2nd reincarnations is one regeneration and so on. So when the 11th doctor(Matt) turned into the 12th doctor(Capaldi), he still has one more regeneration before he has used all 12 regenerations.
If what you say that he got a new regeneration to regenerate into Capaldi, the doctor would have only regenerated 10 times before he regenerated into Capaldi, which can't be right.
Do the math, folks.
