Props to 13 for remembering they don't have to risk crashing the TARDIS in the process.

The Tenth Doctors regeneration will never cease to bring tears to my eyes. The desperation of the doctor who regenerated once before but couldn’t hold himself back anymore…who was all alone and all his friends were left behind…the end of era. Eleven will always be my second favorite, but Ten always lives on…especially now with his latest appearance

They're all amazing in their own way. But as touching as it is, I can never get over the fact that Matt and Karen were both bald for different projects when they filmed his regeneration scene and had to wear wigs.

The fact that Tennant feels his mouth as the first thing he does as a direct homage to when he first became The Doctor, truly brilliant! The man stepped back in as if he never truly left the role.

"I will always remember when the Doctor was me" - It still hurts today...

The Eleventh doctors regeneration will always be the greatest. The music, the speech, Amy showing up, taking the bow tie off, even the capaldi scene afterwards is brilliant

Matt Smith's final speech as the Doctor will always be one of the best speeches.

All these years, all the Doctors that have come and gone.....the Tenth and the Eleventh will always have a place in my heart for the rest of my days

I’m realising the thing I love most about Thirteen’s regeneration is that where all the other modern regenerations are played as sad (or at least bittersweet), hers feels triumphant. She’s been who she wanted to be, so she goes out with no regrets.

I still think 9 has the best regeneration scene of the new series. It's not overly dramatic or self-serving, just a short goodbye, and then he changes.

I find it rather poetic that David Tennant’s theme plays over the shot where we see Jodie Whittaker’s face for the first time, given who she ultimately ends up regenerating into.

Chris Eccleston is the most underrated Doctor, so much love for the guy who revived the show and introduced DW to an entire new generation, myself included. His stint may have been brief, but my god did it pack a punch! That said though, my favourite Doctor is still 10, for me he's the standard against which all modern iterations are measured.

David Tennant's regeneration will live in my head rent free for years. Knowing they shot 4 different ways of him saying "I don't want to go", they picked the perfect one! None of us wanted him to go 😂

I love Capaldi saying goodbye. He's such a great fan of the show and he knew he had to give a great speech. And of course: 25:23 "Oh, brilliant!"

Despite 10 being my favourite doctor, 12's first scene is 100% my favourite its the funniest and his confusion is captured really nicely.

I like that the Doctor finally realized maybe they shouldn't do a giant regeneration inside the TARDIS

Loved how 13's regeneration was so graceful, like she was releasing the old and embracing the new...dope

“I don’t want to go” still gets me.

Matt for sure has the best first scene The music change to the funky riff, the energy and life he brings, running around trying to pilot a crashing TARDIS with not an ounce of tension or fear he's just enjoying it like a mad man, and if course yelling Geronimo at the end. Not just Matt but the production quality in general, everything just works so well

The Ninth Doctor's introduction is perfect, Rose should be studied in writing classes as an example of how to write a first episode

God there really is no better intro that 9. “Run” absolute fantastic

I’m just turning 64 in a couple of weeks and I have watched EVERY…SINGLE…EPISODE… of Dr Who since the very beginning!!! Biggest fan ever, even my phone has the DR WHO theme song as my ring tone. ❤

Capaldi is definitely the best actor to play the Doctor in the revival. He managed to salvage so many questionable decisions with regards to the writing through sheer acting skills.

Not gonna lie here. Im a 45 years old men and this show made me cry manly tears more often than ANY other show i´ve ever watched.

I always loved Peter Capaldi's look in his final season. I wish they had had the idea to letting his hair grow out sooner. Kind of allowed him to actually look like the crazy old man in a blue box. 11 to 12 replaced my favorite regeneration, which was 5 to 6, and is my second favorite. Though 12 to 13 ranks up there with them both.

I like eccelsons the most I think it’s how by the end you can see through his rough external and see that he was truly one of the most loving iterations of the doctor

11s regeneration, although not my favorite, will never fail to entertain me, simply because of Clara's reaction to it. One second, she's saying goodbye to her beloved best friend, the next, she's staring into the furious eyes of a rabid Scotsman 😂😂😂

I do love matt's speach at the end and amy and the fact they were both weraing wigs. I also love peters goodby

Capaldi’s goodbye still destroys me. The speech, the music, the pain of letting go. Just stunning. And when he falls to the fall, is that him grabbing his kidneys?? Did he finally like the colour? I love it. And then Jodie! “Oh brilliant,” indeed.

“Dr whoever I’m about to be…..Tag, You’re It!”

9th's Intro: 0:00 9th's Goodbye: 4:05 10th's Intro: 6:39 10th's Goodbye: 9:10 11th's Intro: 11:37 11th's Goodbye: 13:40 12th's Intro: 17:02 12th's Goodbye: 21:22 13th's Intro: 24:43 13th's Goodbye: 30:08 14th's Intro: 31:15

No one's talking about it but I love how 13 crash lands into a train then immediately sprung into action.

The Tenth Doctor's regeneration still gets me emotional no matter how many times I see it 😢

Fun how it almost looks like Rose went from running by the Tardis to waking up lying inside it- clothes very similar

Watching this has so much emotional whiplash from excitement to sadness and back again each scene evoking the thought of times to come and what has been. Change is good, change is sad, change is exciting. And I'm excited for what is to come.

This show was the first show I discovered as kid! Over 20 years of being a fan ❤ always ready for a new adventure with doctor I hope this show never ends because when I have kids they will be watching this 😢❤

The regeneration scenes are both heartbreaking and awesome at the same time if you get what I meant

Even if you don't gel with a doctor, there's ALWAYS a sense of melancholy when its time to say goodbye

My favorite regeneration is still 10’s. Not only is he the best Doctor, but his regeneration was the best (and also the saddest thing in the series). It’s so devastating seeing that he’s not yet ready to regenerate (which makes sense bc timeline-wise, he had the shortest span). He doesn’t have a big long speech, and instead, we see this man who we all love and have seen as a hyperactive man-child who disguises his crippling loneliness die alone. After all the torment he went through in the episode, here is is, dying alone and letting us see his heartbreak. 10 let us into the Doctor’s emotions and mind more than any other Doctor, and when he’s leaving we once again see his vulnerability and heartache. And his vulnerability in the scene coupled with the torment he went through just makes it all the more real (and painful).

10 years, it's been over 10 years, I have a child, a new partner, and to this day I still remember 9s send off speech verbatim, he really was brilliant

The 10th saying “I don’t want to go” breaks my heart

I can never sit through Tennant's regeneration and not cry. its the "I don't wanna go" that gets me every time.

The VFX whizz and the Thirteenth Doctor's era stalwart Ben Pickles puts it: "There's only so many times you can watch the Doctor destroy their own home before you start to go. 'Uhh, maybe step through that door that's 15 feet away?' "So logically I think it makes a lot of sense. If you could choose where to die, why wouldn't you pick a clifftop at sunrise? Plus, it frees up the regeneration energy to be as big and beautiful as possible. There's literally no ceiling on how huge you can make it."

The tenth and forteenth Doctor shall always be my favourite ❤

Nine's regeneration: he was fantastic Ten's regeneration: he didn't wanna go eleven's regeneration: beautiful- oh btw do you ever sneeze so hard that you just become Peter Capaldi

The Tenth doctor is, and always will be, THE Doctor.

11 and 12 will forever have my favorite scenes. Their speeches, music, and monologues, not just then, but throughout their whole run as The Doctor will always be my favorite.

Try to be nice, but, Never fail to be kind. We need more of that here Doctor.

These are always fun and sad to see at the same time. You get a glimpse of what is and what it was with each regeneration.

Murray Gold's soundtrack is just perfect ❤

Matt Smith brought me into the fandom and is my favorite Doctor Who.

Now you gotta do the classic series. Despite the modern being great, the classic is iconic ;D

This is awesome as it glimpses each doctor saying goodbye and regenerating

"NEVER EVER EAT PEARS" oh and "Laugh Hard. Run Fast, Be Kind!"

It feels like The Doctor's Regenerations reflect their emotional state at the time of letting go? Ten's Regeneration was destructive and violent because he fought not to go, whereas Eleven was completely at peace with his death and leaned into his regeneration, so easily flashed into Capaldi. Capaldi wasn't fighting, but he delayed Regenerating to caution Thirteen, so his Regeneration was more destructive than Nine or Eleven.

i love the 11th doctor, he is just amazing, funny and even accepted the regeneration as a part of being the doctor

I really like every doctor in their own way ❤

I noticed that Capaldi resembles the War Doctor, which has me wondering whether that Doctor's mind was fighting with the other selves to regain control of their single body.

11's first was the definition of madman in a box.

I could watch the 13 to 14 transformation sequence all day long. Gosh. I am so excited

ngl the doctor who series is brilliant to have a protagonist who can regenerate, one of the few shows that can hypothetically exist sort of forever-

David is basically the Tom Baker of the modern era of Doctor Who.

I love that 13’s last words were “doctor whoever I’m about to be, tag you’re it” cause in a way that’s how she came into the role. Tennant was told “the newest doctor wants to give you a call” and when her name popped up he welcomed her as a fellow doctor. So her “tagging” Tennant back into the role is like it all coming full circle

I think eccleston's doctor was so underrated i feel like he deserved 3 seasons just like the others

Love the 12th speech regeneration a and it is all what Jodie is in her era.

I really wish CAPALDI had a least a 4th series. There was something about Series 10 which really got Capaldi going, felt like a fresh reset. But I’m glad that in this universe we got him as the Doctor :)

This show is the greatest!😍

11th regeneration always brings me tears. I cant stop it.

The 13th Doctor regeneration was beautiful!😢 I love it when 13th said Tag, you are it!😭 She was so childish! 😊 I love it! So cute! 🥺

I love this show.

Ten is my favorite Doctor but Eleven’s regeneration is the most beautiful. Between the speech, the music and just the way it’s done makes me cry every time

Old man Doctor’s farewell will always be the greatest.

22:33 gotta love the David tenant doctor callback

the speech 11 gave was perfect

Caption: "[Faint vworping.]" I hadn't realized that the production team had finally come up with a spelling for the TARDIS noise. 😀

Amy - "Raggedy Man" yeah that killed me.

Love some comic relief after an emotional regeration scene 😢 "Well, here we go again!" "Change, my dear. And it seems, not a moment too soon" "I hope the ears are a bit less conspicuous this time" "Just one question... do you happen to know how to fly this thing?" Classics 🤣🤣🤣🤣🤣

"IV'E GOT NEW KIDNEYS, I don't like the colour" will still be my favourite Capaldi quote

"Nice to meet you Rose, Run for your life!" Lmao

I’m so glad David Tennant returned

He really did get two heads

13 had a lot of problems, but at least she finally figured out that regenerating inside the Tardis causes it to crash.

Thanks 👍

The 10th Doctor regeneration to 11th always brings tears to my eyes no matter how many times i seen it

Matt will always be my favorite doctor but I’m excited for another decade of Doctor who

The dying 13th Doctor finally learned the most important lesson of time vortex traffic safety: don't drive under the influence of regeneration!

"Laugh hard, run fast, be kind" sensational last words

"I don't want to go" my favourite 😢

“nice to meet you rose, run for your life” 💀

I dare say 13's final line is just as iconic as 10's. Definitely sticks in my memory.

I feel like in each regeneration, the actors themselves share their own thoughts as well as their Doctor’s: Eccleston explains the process for the new fans, compliments his costar for a job well done, happy that the reboot was a success. Tennant seems to have just processed that this is last scene, and realizes he wasn’t ready as he thought he was. Smith swears to always remember when the Doctor was him, as if he’s thanking everyone for the unforgettable experience of being such a beloved character. Capaldi prepares to pass the torch, taking time to remind his successor what the Doctor stands for. Whittaker is a little sad to go, but is also excited to see what comes next. I don’t claim to know the thoughts of the actors, and I apologize if I got anything wrong, that’s what I feel is being said in each regeneration.

Few things make me feel as old as seeing David Tennant beginning and end side by side.

18:07 I love that sound "Shush")

We love you, David. Can't wait to see you and Catherine together again xx

I love this ❤

I love that the tardis goes to earth when it crashes from David to Matt's transition did anyone else pick up on the fact that it crashed in Scotland which was a nice little touch i thought to David being Scottish

I loved Capaldi's "Kidneys! I've got new kidneys! I don't like the color."

David Tennant

10th doctor is emotional and glad he is back

It's going to be so good to hear 13's theme again when she makes her inevitable appearance in an anniversary special.
