Yes.

The Sixth Doctor regenerated, just as Atlantis was destroyed, multiple times.

Since 1987 the Sixth Doctor regenerated in after "The Ultimate Foe" in "Time and the Rani."

Carrot juice, carrot juice, carrot juice.

Since 1988 the Sixth Doctor regenerated in the above and in "Time and the Rani" (novelisation).

(What is it?)

I don't know. The slide control for setting time and space co-ordinates seems to be stuck!

(This isn't operational either.)

Take a look at the computer read-out screen.

Since 2005 the Sixth Doctor regenerated in all of the above and in "Spiral Scratch."

Don't cry Mel. It was my time. Well, maybe not, but it was my time to give. To donate. I've had a good innings you know, seen and done a lot. Can't complain this time. Don't feel cheated.

(It's not fair!)

Yes. Yes it is... Local... tractor beam...

Since 2008 the Sixth Doctor regenerated in all of the above and in "Time's Champion."

You want me to become a god?

Since 2015 the Sixth Doctor regenerated in all of the above and in "The Brink of Death."

Oh, so that's it? Oh, well I've had a good innings. All those lives I've lived. I hope the footprint I leave will be light, but apposite.

(It's far from being all over)

Who said that? Who's there?

Change, I feel it. Yes, I will regenerate.

(Yes, I will regenerate.)

Our future is in safe hands.
