List of causes of regeneration

The causes of regeneration, especially amongst Time Lords, were many and varied.

They ran the gamut from simple desire to change to sentencing for convictions, to life-threatening maladies, to blunt-force trauma. While all of these might have been cause for alarm in humans, Time Lords sometimes expressed much less concern. As the Twelfth Doctor once told Clara, "Death [was] Time Lord for man-flu". (TV: Hell Bent)

The following are the known causes of regeneration of specific Time Lords or other regenerating idividuals.

Ruath

 * Ruath drained every drop of her blood from her body to restore Vampire Lord Yarven. Yarven subsequently turned her new incarnation into a vampire. (PROSE: Goth Opera)

Ophiuchus

 * Dying from an unknown cause, Ophiuchus was saved by the Fifth Doctor who gave him a "little push" having been convinced by Nyssa and Tegan and regenerated. (COMIC: Ophiuchus)

Innocet

 * Innocet was killed by a Quences-possessed Badger to protect the Doctor. (PROSE: Lungbarrow)

Glospin

 * Glospin force-regenerated himself into the double of the First Doctor after acquiring a genetic sample to influence the appearance of his next incarnation. (PROSE: Lungbarrow)
 * Having killed Quences while disguised as the Doctor, Glospin regenerated again to conceal his role in the murder. (PROSE: Lungbarrow)

I.M. Foreman

 * As a priest, I.M. Foreman had been given the gift of regenerations. This made twelve different individuals, who were created by his body absorbing the DNA around him; all regenerations were caused by the Third Doctor sending Foreman's first twelve bodies back to Gallifrey's past so that they fell from a great height, each regenerating into their next body, the trauma of the regeneration causing each incarnation to lose their memories. (PROSE: Interference - Book One, Interference - Book Two)

Cavis

 * Celestial Intervention Agency agent Cavis nearly regenerated after she was decapitated by Queen Regent Mab, but Mab also stabbed her in both hearts to ensure that she remained dead. (PROSE: The Shadows of Avalon)

Epsilon Delta

 * A run-in with some Sontarans triggered Epsilon Delta's first regeneration. (PROSE: The Dimension Riders)

Gandar

 * Celestial Intervention Agency agent Gandar was stabbed in the heart by Margwyn but regenerated as Margwyn missed his second heart. (PROSE: The Shadows of Avalon)
 * Gandar regenerated again shortly after his previous regeneration when he received a fatal sword wound; his new incarnation resembled a hybrid of human and Silurian and was far more peaceful than his previous violent selves. (PROSE: The Shadows of Avalon)

Louis

 * Louis's first regeneration was triggered by a staser-gun blast inflicted by Rigan. (AUDIO: Unregenerate!)

Elbon

 * Surgeon-Master Elbon was shot by a servitor that Irving Braxiatel placed in the TARDIS that Romana II used whilst trying to bring a pair of Pig-rats back to Gallifrey. His next incarnation was hijacked by the Dogma Virus. (AUDIO: Panacea)

River Song

 * As a little girl, Melody Pond, later known as River Song, regenerated on the streets of New York City in 1970 due to a terminal illness. She ended up as a toddler upon her regeneration. (TV: Day of the Moon, Let's Kill Hitler)
 * In her second incarnation, known to Amy Pond and Rory Williams as Mels, Melody regenerated in Hitler's private study in 1938 after the Führer accidentally shot her while aiming for the Teselecta. She later used up all of her remaining regenerations to heal the Eleventh Doctor from a poison with which she had infected him. (TV: Let's Kill Hitler

Volstrom

 * In quick succession, Volstrom was forced to regenerate at least four times having been repeatedly shot by the Eleven using a staser modified to allow for regeneration as a means of torture, changing from male to female form then back to male then female again. (AUDIO: Songs of Love, The Side of the Angels)

Proto-Time Lords

 * Brooke regenerated for the first time after being shot by River Song. (AUDIO: My Dinner with Andrew)
 * Lake's first regeneration was induced after he was mortally wounded by an unstable fuel cell. Seeking to determine the number of times he could do so, he tested the ability of his fellow Proto-Time Lords by inflicting fatal injuries on them or convincing them to commit suicide. Ironically, Lake's last victim was his third and final incarnation, a girl who became known as Lily after losing her memory of her prior lives. Having witnessed Lake regenerate into Lily after mortally wounding him in anger for murdering her, River Song was forced to send Lily back in time so she would meet her fate. (AUDIO: The Lady in the Lake)
 * Wadi's regenerations were all expended through fatal injuries inflicted by Lake. (AUDIO: The Lady in the Lake)
 * As part of his religious cult, Lake convinced Stream, Beck and Creek, to die multiple times on Terminus Prime so he could covertly study regeneration and find out how long he was able to live. (AUDIO: The Lady in the Lake)
 * Rindle first regenerated after being mortally wounded by a wild beast. He regenerated again, this time into a female form, by Lake when he mistook him for an imposter. Catching up with her, Lake forced to regenerate again, now becoming an older man, before expending Rindle's remaining regenerations to power his ship. (AUDIO: The Lady in the Lake)
 * Deceived by Lake into believing that regeneration was a constant rebirth, Tarn went to Terminus Prime to commit suicide so he could continually be born again. By the time he met River, he had already died eight times. He was killed again by Kevin and then again by Dave, regenerating at least ten times. (AUDIO: The Lady in the Lake)
