Prophecy

During the course of Doctor Who, many prophecies have been made by those with psychic abilities.

Evelina and Lucius Petrus Dextrus
During their time in Pompeii, the Doctor and Donna Noble end up encountering Evelina and Lucius Petrus Dextrus who both posses telepathic abilities and the ability to see into the future as a result of the Pyroviles and a crack in time opened by Vesuvius' eruption. As a result, they make some startling prophecies about the Doctor and Donna's futures and pasts. (DW: The Fires of Pompeii)

Evelina

 * Evelina is able to tell that the Doctor and Donna aren't who they say they are and that the Doctor's name is not 'Spartacus' as he told her, and that Donna calls herself Noble (her last name). She is also able to tell that they both came from far away.
 * Evelina also predicts that the name 'Doctor' is false, and that his true name is hidden in the Cascade of Medusa herself.
 * Evelina is also able to predict the Doctor's true nature.

Lucius

 * When pressed, Lucius is able to tell that the Doctor is from Gallifrey and Donna from London.
 * Another prediction of his is to the Doctor: "She is returning".
 * He predicts that Donna has "something on her back".

Fulfillment

 * Evelina's prediction about the Doctor's name is likely about the Medusa Cascade and how there Davros named the Doctor the "Destroyer of Worlds."(DW: Journey's End)
 * Lucius's prediction "She is returning." refers to Rose Tyler's return, which occurs in Turn Left and The Stolen Earth.
 * Lucius' prediction that Donna has something on her back comes true in Turn Left: a Time Beetle attaches itself to her back and she ends up with many people pointing that out to her alternate self until she gets rid of it by changing time with Rose Tyler's help.

Dalek Caan
Due to travelling into the Time War, Dalek Caan saw all of time and space, past, present, and future. The experience drove him insane, but it also allows him to realise just how evil his race really was, and work to orchaestrate their downfall. (DW: The Stolen Earth/Journey's End)

Prophecies

 * Dalek Caan predicts that the Doctor is coming and refers to him as the "three-fold man."
 * Dalek Caan predicts that the Doctor's Children of Time will gather and that the most faithfull one will die. He predicts this repeatedly, his last words being "one will still die" as his final prophecy.
 * Dalek Caan also predicts that the Doctor's true soul will be revealed.
 * Dalek Caan predicts the end of the Dalek race due to their evil and foresees that the Doctor will be the one to do it.

Fullfilment

 * Dalek Caan's prophecy of the Doctor as the "three-fold man" ends up refering to the three Doctors that converge to stop the Daleks: the Tenth Doctor, the Meta-Crisis Tenth Doctor and the DoctorDonna.
 * The Doctor's companions gather to aid him in dealing with the Daleks, summoning him and aiding him in battle. While none actually die, Donna Noble's memory of the Doctor is erased to protect her as her Time Lord side was too much for her human mind to bear. Thus, the person she became due to the Doctor essentially dies.
 * Davros claimed that when the Doctor's companions threaten mass destruction to stop the Daleks the truth about the Doctor is revealed: he is a man that refuses to use a weapon, but molds his companions into ones.
 * Dalek Caan pushes the Meta-Crisis Tenth Doctor to fulfil the prophcy about the Daleks destruction and causes him to realize it needs to be done. With Dalek Caan's insistance, the Clone Doctor destroys the Daleks.

Carmen
Carmen naturally posseses low-level telepathic powers which seemed to be enhanced as a result of her visit to San Helios. As a result of her powers, she makes a startling prophecy which the Doctor realizes predicts his death. (DW: Planet of the Dead)

Prophecy
As she says goodbye to the Doctor, Carmen makes a prophecy about his future telling him "Your song is ending sir.... It is returning. It is returning through the dark, and then Doctor, oh, but then...He will knock four times."

Fulfillment
The Doctor does everything he can to stop this prophecy from happening, even electrocuting Andy to prevent him from knocking four times, but it proves inevitable. Eventually when The Master is responsible for bringing back the Time Lords, the Doctor realizes what "it" is: as a result of breaking the time-lock on the Time War, the Master has brought back more than the Time Lords, he has brought back Gallifrey, the "it" from Carmen's prophecy that was returning. Gallifrey ends up returning in orbit of Earth and nearly destroys Earth. After the Doctor and the Master defeat the Time Lords and banish them and Gallifrey back into the Time War, the Doctor believes that he is safe and has averted the rest of the prophecy when four knocks sound. It turns out that "he" is the Doctor's companion Wilfred Mott who knocks four times repeatedly to get the Doctor's attention in order to be set free from a radiation booth he got trapped in freeing a man. In order to save him, the Doctor must sacrifice himself and absorb a fatal dose of radiation or let Wilfred absorb it and die. The Doctor saves Wilfred which causes him to absorb the fatal dose of radiation and eventually regenerate. Thus the Tenth Doctor dies and the Eleventh Doctor is born. (DW: The End of Time)

The Ood
On the Ood-Sphere, Ood Sigma tells the Doctor that his song 'must end' soon. (DW: Planet of the Ood) When the Doctor later returns to the Ood-Sphere, the Elder Ood is chanting a ritual prophecy that:


 * 'It' is returning.
 * 'They' are returning.
 * 'He' is returning.
 * Both 'he', it' and 'they' are returning, but too late.

Fulfillment
The 'he' eventually turns out to be the Master, who has been brought back to life. The Master, then transplanted himself into every Human on Earth. When all the new Masters concentrated on the drumming inside his head, he was able to pinpoint it's point of origin. This meant that the High Council of Time Lords, who retroactively implanted the signal in his head when he looked into the Untempered Schism, were able to sent a Whitepoint Star to Earth, making contact physical. This was the 'they'. But, along with them, Gallifrey also came through, the 'it'. (DW: The End of Time)

The Trickster
When The Doctor encountered the Trickster, he was told 'The Gate is waiting for you'. (SJA: The Wedding of Sarah Jane Smith) The 'gate' in question was the Immortality Gate, which flooded the Doctor's body with Vinvocci radiation, forcing him to regenerate. (DW: The End of Time)
