Darkelvoriplorellion Tyler-Lungbarrow

Darkelvoriplorellion Tyler-Lungbarrow, who insists on being called the Scholar, is the second biological daughter of both the Doctor and Rose Tyler-Lungbarrow. Darkel has a particular interest in explosives and it is her dream to learn Ace McShane's recipe for Nitro-9.

Pond Era
Darkel was born five years before the Doctor regenerated into his eleventh form. She was present, along with Lilith and Rose, during the regeneration. She stayed behind in the TARDIS both when her parents first met Amelia Pond and when they returned 'five minutes later'. During the time that the Ponds were traveling with the family, Darkel usually stayed on the ship or was dropped off with her godparents, Martha and Mickey Smith.

Big Bang Two
After the Doctor reset the universe, Darkel was placed in an orphanage. She was living in Cardiff when Rose, Lilith, Jack, and River found her. She stayed in London when Lilith went to Leadworth for the Pond-Williams wedding.

Post-Big Bang Two
After the Doctor was brought back into existence, Darkel joined her family and the Ponds in their adventures. She was not at Lake Silencio when the Doctor was killed, but was waiting with Lilith and Rose at the diner. Neither the Doctor nor Rose (nor Jack or Lilith) let Darkel participate in the Battle of Demon's Run. She was there when the Ponds were taken by the Weeping Angels, unable to console her sister after the loss of two of her best friends.

Clara Era
Darkel participated in all of the adventures that the family had with Clara Oswald.

Second Incarnation
At some point during after Lilith and Jenny went off on their own, Darkel regenerated into her second body. Unhappy with her new blonde hair, she dyes it blue instead.

Clara Era
Darkel participated in all of the adventures that the family had with  Clara.

Post-Clara Era
She continued to travel with her parents and siblings, save Jenny and Lilith, after the Doctor lost his memories of Clara.
