Introduce a little anarchy. Upset the established order, and everything becomes chaos.
All of the regenerations from the new series, presented in timeline order:
1. Eighth Doctor to War Doctor (The Night of the Doctor)
2. War Doctor to Ninth Doctor (The Day of the Doctor)
3. Ninth Doctor to Tenth Doctor (The Parting of the Ways)
4. Professor Yana to The Master (Utopia)
5. Tenth Doctor regenerates to heal (Journey’s End)
6. Tenth Doctor to Eleventh Doctor (The End of Time)
7. River Song’s first regeneration (Day of the Moon)
8. River Song’s second regeneration (Let’s Kill HItler)
9. Eleventh Doctor to Twelfth Doctor (The Time of the Doctor)
The regeneration scene from The Impossible Astronaut is not shown because it was not a canonical regeneration, it was the Teselecta imitating one.
