There, he encountered the dying War Keeper, the ancient controller of the population of the Disjointed Planets. To find a worthy successor, the War Keeper scanned the Doctor's mind for the identity and location of the greatest leader in the cosmos.

He chose Brigadier Alistair Gordon Lethbridge-Stewart , now retired and in his late seventies, who refused to accept the War Keeper's demands. As an alternative, the War Keeper chose Mike Yates , but accidentally summoned another man with the same name. Rivals of the dying War Keeper infiltrated his helpers before his death and passed onto Yates the Keeper's control device, the Warkeeper's Crown. With the weak-minded Yates under the control of the Crown and the many forces of the Disjointed Planets, the deceased War Keeper's rivals planned to control the conflicts.

The controlled Yates transported himself back to Earth, along with many Orcs, Hawks and other creatures. The Doctor and the Brigadier, with an army of Brigadier clones the Doctor created with technology at the Slough, returned to the Earth to defeat the demon hordes and free Yates from the Crown's control.

Despite succeeding, their incantation was reversed by one improvised by Shakespeare, trapping them and all copies of the play in the Darkness. As it risked freeing them, the Doctor advised Shakespeare not to rewrite the play. While bidding Shakespeare goodbye, Queen Elizabeth I arrived and ordered her men to kill the Doctor, declaring him her sworn enemy, much to Martha's confusion and the Doctor's amusement.

TV : The Shakespeare Code. Fleeing the Queen's men, the Doctor decided to stretch the one trip agreement with Martha to include a trip to the future. Searching for her, the Doctor discovered the city had been plagued and the population had become trapped on the motorway for their own safety.

Appearing in the 50th anniversary special, John Hurt's War Doctor was a fleeting but welcome addition to Doctor Who canon and was seen regenerating at the end of "The Day of the Doctor.

For the second time, the Doctor sacrifices himself to save an assistant. Rose refuses to accept being unable to help the Doctor and strives to find a way back to him, eventually absorbing the heart of the TARDIS and gaining God-like abilities. Rose saves the day but is rapidly becoming unstable, forcing the Doctor to absorb the power himself via a painfully cheesy kiss.

After restoring the TARDIS energy back to its original location, the Doctor begins to feel the effects of saving Rose, later claiming that no Time Lord is supposed to take in that much power.

He promptly regenerates into David Tennant. David Tennant 's demise was a long time coming in Doctor Who , with the "he will knock four times" warning coming well in advance of the Tenth Doctor's final episode. Viewers were misled into believing this prophecy would be fulfilled by the Master or Rassilon but, in the end, it was Bernard Cribbins' Wilf that heralded the end of the Tenth Doctor's reign.

During the dramatic final confrontation of "The End of Time," Wilf selflessly frees an innocent worker from a two-man radioactive chamber, locking himself in until another person can take his place. When the dust settles, the Doctor hears the gentle knocking and realizes he must sacrifice his own life to save Wilf, absorbing a deadly dose of radiation in the old man's stead.

After a whirlwind tour of his old friends, the Tenth Doctor delivers an emotionally devastating final line and regenerates in explosive fashion.

After deterring the potential conflict for the remaining years of his Eleventh iteration, the Doctor consigned himself to a death of the permanent kind, but was spared this fate by the Time Lords, who granted him a brand new regeneration cycle. Peter Capaldi's regeneration was special in the sense that it was triggered by damage accumulated throughout the Twelfth Doctor 's final adventure.

Coming up against a powerful army of Cybermen and two incarnations of the Master, the Doctor's first major injury arrives in the form of Cyberman electrocution.

Although the Doctor survives, he spends several weeks recovering from the attack and is unable to heal a cut on his forehead, with golden regeneration energy beginning to brew from his hands. Delaying his forthcoming renewal, the Doctor later engages multiple Cybermen in combat and endures several energy blasts before detonating an explosion that not only wipes out his mechanical enemies, but puts paid to any chance the Doctor had of recovering from his previous wounds.

Capaldi's regeneration marks a rare occasion in Doctor Who history that a major villain has succeeded in directly killing the Doctor.
