Over the classic span of Doctor Who, fans have witnessed a total of 14 canonical Doctors. Each incarnation has bravely faced both their inaugural and final villains. The series is renowned for its compelling narrative arcs where the Doctor encounters a myriad of antagonists, frequently meeting them more than once throughout their journeys. From iconic foes to enigmatic threats, each Doctor’s battles have shaped their character development, with serious repercussions—some leading to regeneration following fatal encounters.
Notably, the timing of these confrontations adds an intriguing layer to the storylines. There are instances where neither the Doctor nor the audience realizes that they are confronting their last adversary before a transformation occurs. The villains encountered typically mirror the character arcs of the respective Doctors, with the Time Lord saving the universe from perilous threats over an impressive 61-year legacy.

First Doctor
The Daleks & The Cybermen
In his debut serial, “An Unearthly Child,” the First Doctor did not encounter a definitive villain. The true adversarial encounter occurred in his subsequent adventure, “The Daleks,” featuring one of the franchise’s most notorious foes. This choice was fitting, considering the Daleks’ prominence in the show.
The First Doctor’s journey met its end in “The Tenth Planet”while fighting the Cybermen. Though their conflict did not directly cause his regeneration, it ultimately became the catalyst leading to his demise as he valiantly defended Ben and Polly against them.

Second Doctor
The Daleks & The War Lord
Following his regeneration, the Second Doctor confronted the Daleks once more in “The Power of the Daleks,” a serial now partly lost to history but later restored through animation. In this narrative, the Second Doctor encounters the Daleks in a servant role on the planet Vulcan.
He met his final nemesis, the War Lord, in the epic serial “The War Games.”This formidable character orchestrated battles among Earth’s soldiers for amusement. While the War Lord commanded an army of faceless aliens who contributed to the chaos, he was the true mastermind behind the conflict, ultimately leading to the Doctor’s exile for his actions.

Third Doctor
The Nestene Consciousness/Autons & The Great One
The Third Doctor made his debut against the Autons in “Spearhead from Space.” Despite having clashed with these plastic foes before, it was under this incarnation that they truly left a lasting impression by striking fear into the heart of shopping enthusiasts everywhere.
His final battle unfolded in “Planet of the Spiders,” where he faced the Eight-Legs’ leader, The Great One. This imposing figure utilized Metebelis crystals, resulting in devastating consequences for the Doctor. His victory led not only to saving others but also triggered his own regeneration.
11
Fourth Doctor
Hilda Winters & The Master
In “Robot,”the Fourth Doctor’s journey begins with a formidable challenge against Hilda Winters, an unsung villain in the series. While the K1 robot presented a physical threat, Winters’ manipulative nature earned her the role of the primary antagonist.
The Fourth Doctor squared off against his greatest nemesis, the Master, in “Logopolis.” Anthony Ainley’s portrayal of the Master brought chaos to this episode, showcasing his villainy through elaborate schemes that ultimately lead to the Doctor’s own end.

Fifth Doctor
The Master & Morgus
The Master, who had been the Fourth Doctor’s nemesis, re-emerged as the Fifth Doctor’s first adversary in “Castrovalva.”Escaping the grips of the Master became imperative as the Doctor navigated a web of deceit crafted by the villain, who cleverly disguised himself as a figure of assistance.
The Fifth Doctor’s conclusion came in “The Caves of Androzani,” as he contended with the ruthless business mogul Morgus. This confrontation not only initiated his regeneration but also served as a cautionary tale of greed and sacrifice within the futuristic landscape.

Sixth Doctor
The Gastropods & The Valeyard
In the “The Twin Dilemma,”the Sixth Doctor faced the Gastropods, a grotesque race of humanoid slugs intent on spreading their eggs across the cosmos. Their leader, Mestor, sought to control the Doctor but was thwarted by the Time Lord’s newfound power following regeneration.
Conversely, the Sixth Doctor’s fate was entangled with the Valeyard during “The Trial of a Time Lord.” Serving as an antagonist who manipulated the outcome of the Doctor’s trial, the Valeyard epitomized a shadowy reflection of the Doctor himself, adding a layer of complexity to the battles of morality within the universe.

The Seventh Doctor’s journey commenced in “Time and the Rani,” which featured the villainous Rani—another Time Lord from the Doctor’s past. Sharing many traits with the Master, the Rani compelled the Doctor to thwart her plans of harnessing the intellectual capacity of historic geniuses.
In his concluding adventure in “Survival,” the Doctor confronted the Master on a mysterious planet where he had been transformed into a Cheetah person. This encounter revealed the Master’s deceptive nature as he schemed against the Doctor, highlighting their intricately woven destinies.

Eighth Doctor
The Master & The Time Lords
The Eighth Doctor’s cinematic debut saw him battling the Master in the 1996 film. Here, the Doctor endeavored to thwart the Master’s catastrophic plan to unleash destruction by exploiting the TARDIS’ Eye of Harmony.
While his official final adversary was the Master, it can be argued that the Time Lords themselves were also indirectly responsible for his downfall. It was their machinations that led to the Eighth Doctor’s transformation into the War Doctor during the devastating Time War.

Ninth Doctor
The Nestene Consciousness/Autons & The Daleks
The Ninth Doctor made a formidable entrance during the 2005 revival of Doctor Who when he battled the Autons, controlled by the Nestene Consciousness, in the pilot episode “Rose.” This encounter not only reintroduced the iconic villains but showcased the Doctor’s resourcefulness as he collaborated with Rose Tyler.

This confounding villain, once hidden in Amelia’s bedroom wall, added a fresh dynamic to the series, demonstrating the Doctor’s adaptability and innovation in confronting new foes.
However, the Doctor’s final confrontation came against a convergence of numerous threats in “The Time of the Doctor,” where the Time Lords played a pivotal role, orchestrating events from their pocket universe, revealing their hidden manipulations throughout the series.

Twelfth Doctor
The Half-Face Man & The Cybermen
In his inaugural episode “Deep Breath,” the Twelfth Doctor confronted the enigmatic Half-Face Man, a Clockwork Droid with an unsettling blend of charm and horror. This encounter set the stage for an intense exploration of morality and identity within the narrative.
Strikingly, the Doctor faced his ultimate adversaries in “Twice Upon a Time,” highlighting the themes of sacrifice and resilience. Although the villainy of the Cybermen was realized in an earlier episode, the true peril lurked in the intermingling of fate and character in the Doctor’s closing struggles.

Tzim-Sha & The Master
The Thirteenth Doctor’s descent into conflict began with the Stenza warrior, Tzim-Sha, threatening her life in “The Woman Who Fell to Earth.”This confrontation laid the groundwork for her relentless spirit as she faced adversity head-on.
In a dramatic conclusion during “The Power of the Doctor,” the Master returned to wreak havoc, demonstrating both his cunning and ruthlessness. His actions catalyzed widespread devastation, leading to a heart-wrenching resolution as the Doctor faced her regeneration amidst the chaos he created.
