10th Doctor[]
The 10th Doctor (TV: Christmas Invasion (TV story) The Christmas Invasion , End of Time (TV story) The End of Time) grew back a hand after the leader of the Sycorax cut one off and he crashed through the roof of the Naismith manor. On both occasions, this was possible due to an excess of regeneration energy. (PROSE: Things She Thought While Falling) He also had a daughter, a connection to a human called Rose Tyler, (PROSE: Kevin and Jenny Take On The Universe(s)) and he and his companion Donna (TV: Partners in Crime) waved to an Adipose. (PROSE: The Complete Story of My Life (So Far))
11th Doctor[]
The 11th Doctor was known to Amy Pond as “the Raggedy Doctor”, having crashed into her backyard shortly after his regeneration from the Tenth. She idolised him growing up (WC: The Raggedy Doctor by Amelia Pond) and later became his companion. (WC: Vincent and the Doctor's Gallery)
12th Doctor[]
The 12th Doctor regenerated in the TARDIS. The damage sustained to the ship caused his successor to fall out and into the skies of Yorkshire as she watched it dematerialise. (PROSE: Things She Thought While Falling)
13th Doctor[]
After the TARDIS dematerialised, the Doctor determined that she could soften her landing enough for the regenerative process to take of her injuries if she landed on the roof of an approaching train. As the roof came closer, she saw its lights go out and deduced something was wrong. Immediately after crashing into one of the carriages, the Doctor jumped up, zapped a creature she couldn't understand and made new friends. (PROSE: Things She Thought While Falling) These friends, Graham O'Brien, Ryan Sinclair and Yasmin Khan, later became her companions. (TV: The Woman Who Fell to Earth)
"Unknown"[]
According to Strax, Tom Baker reprised his role as "Who was that supposed to be, anyway?" in The Day of the Doctor. (WC: Strax Saves the Day)
