Bronze Dalek

Bronze Daleks (PROSE: Engines of War) were the basic Daleks which served during the Last Great Time War and beyond. (TV: Dalek et al.)

The bronze Daleks were subordinate to black Daleks, (TV: Army of Ghosts/Doomsday) Dalek Inquisitor Generals, (PROSE: Prisoner of the Daleks, red Supreme Daleks, (TV: The Stolen Earth/Journey's End) and the Dalek Emperor himself. In addition, the Emperor was protected by the Emperor's Personal Guard; mostly bronze, they were distinguished by their black domes as with their pre-War counterparts. (TV: Bad Wolf/The Parting of the Ways, The Evil of the Daleks)

History
Bronze Daleks fought in a war against the Movellans, (TV: The Pilot) as did earlier Grey Daleks. (TV: Destiny of the Daleks)

Prior to the Time War, bronze Daleks, led by a Black Dalek, saw to the extermination of the Mechonoids. Following this, the Black Dalek was summoned by the Dalek Emperor alongside three high-ranking bronze Daleks. Anticipating the oncoming Time War, the Emperor nameed the four Daleks, who formed the Cult of Skaro; led by the black Dalek Sec, the bronze Daleks were named Thay, Jast and Caan. (PROSE: Birth of a Legend)

Led by the Dalek Emperor, bronze Daleks made up the vast majority of the "billion billion" Dalek Fleet that converged on Gallifrey on the last day of the Time War. Having successfully penetrated the sky trenches, they engaged in the fall of Arcadia, where they were fought by the War Doctor and Gallifreyan soldiers. When the thirteen Doctors saved Gallifrey by transporting it to a pocket universe, the Dalek Fleet inadverently destroyed themselves in their own crossfire. (TV: The Last Day, TV: The Day of the Doctor) The Ninth Doctor, along with the rest of the universe, believed the entire Dalek race to have been wiped out along with Gallifrey. (TV: Dalek)

However, the Doctor found that one bronze Dalek had survived, crashing to Earth in 1962. Eventually, in 2012, it came to the possession of Henry van Statten, who ignorantly named it the "Metaltron". Ultimately, the Dalek, after finding that it had been "contaminated" by Rose Tyler's human DNA chose to self-destruct. (TV: Dalek)

Surviving the war in his flagship, the Dalek Emperor, guarded as ever by the Emperor's Personal Guard, created an army of half a million bronze Dalek of human origin. At the end of the Battle of the Game Station in 200,100, they were all reduced to dust by Rose Tyler, under the possession of the Bad Wolf entity. (TV: Bad Wolf/The Parting of the Ways)

Within a Void Ship, the Cult of Skaro survived the Time War as well, taking with them the Genesis Ark, which contained millions of bronze Daleks imprisoned by the Time Lords. Emerging on Earth in 2007, the Cult were able to open the Ark, unleashing the millions of Daleks who attacked humans and parallel world Cybermen in the Battle of Canary Wharf. However, the conflict was soon ended when the Tenth Doctor and Rose Tyler opened the Void, resulting in the millions of Daleks and Cybermen being sucked into it. The Cult were forced to perform an emergency temporal shift to escape. (TV: Army of Ghosts/Doomsday) Those contained within the Void were eventually destroyed as a result of the reality bomb. (TV: The Next Doctor)

Appearing in New York in 1930, the Cult attempted to rebuild their race in the Final Experiment. Discarding his casing to assume the form of a Human-Dalek, Sec collaborated with the Doctor to combine Dalek and human DNA, believing that the Daleks could only survive with humanity's thought and emotions. This, however, put him at odds with his bronze subordinates, who overthrew him with Caan taking command. After Sec gave his life to save the Doctor, Thay and Jast were destroyed by Dalek-humans infused with Gallifreyan DNA, who were then terminated by Caan. Rejecting an offer by the Doctor to help him, Caan used an emergency temporal shift to escape. (TV: Daleks in Manhattan/Evolution of the Daleks)

Breaking the time-lock to enter the first year of the Time War, an act which ultimately cost him his sanity, Caan rescued Davros from death. Using his own DNA, Davros proceeded to create a New Dalek Empire composed mostly of bronze Daleks with a red Supreme Dalek. Though this Supreme Dalek usurped Davros' as ruler, he did allow Davros to remain aboard the Crucible alongside the mentally broken Caan, whose half-broken casing his Dalek mutant form.

Gathering 27 stolen planets in the Medusa Cascade, the Daleks launched a brief invasion in which they easily overwhelmed human military forces, sustaining only minimal casualties at the hands of the Children of Time. Notably, one Dalek chose to spare the life of the young Adelaide Brooke, who it recognised as a fixed point in time. (TV: The Waters of Mars) Ultimately, the New Dalek Empire was destroyed by the Meta-Crisis Tenth Doctor, who used the Daleks' Dalekanium power feed against them. (TV: The Stolen Earth/Journey's End)

A single Dalek ship, containing three Daleks, survived an encounter with the Doctor, taking with them a progenitor; while this progenitor had the potential to restore the Dalek race, it would not recognise these Daleks' DNA. As a single bronze Dalek remained aboard, the other two masqueraded as Ironsides, ostensibly the creation of a human scientist, actually a android created by the Daleks, for the British war effort in the Second World War. In reality, the Daleks' plan was to lure and provoke a testimony from the Doctor, which would confirm them as Daleks to the progenitor. After a month in 1941, this succeeded as the Eleventh Doctor identified them as Daleks, thus enabling the creation of a New Dalek Paradigm. Sporting larger casings, the new paradigm consisted of five archetypes which included a red Drone Dalek, subordinate to the white Supreme Dalek. The older three Daleks, who were deemed as "inferior" by their successors, allowed themselves to be exterminated before the new Daleks departed to rebuild their race. (TV: Victory of the Daleks)

For a while, the red Drone Daleks appeared en masse as the foot soldiers of the Dalek Empire. (GAME: City of the Daleks, COMIC: The Only Good Dalek) However, a Parliament of the Daleks was later established, led by the Prime Minister of the Daleks. Bronze Dalek drones made up the vast majority of the parliament, subordinate to the New Dalek Paradigm archetypes. Other bronze Daleks, that had survived encounters with the Doctor, were among those classed as insane and taken to the Dalek Asylum. Oswin Oswald, a human that had been converted by the Dalek inmates, was contained in a bronze casing. Ultimately, she andt he insane Daleks died when the asylum was destroyed by the Parliament of the Daleks. (TV: Asylum of the Daleks)

Bronze Daleks participated in the Siege of Trenzalore, (TV: The Time of the Dalek) and the war with the Combined Galactic Resistance. One of them, named Rusty by the Twelfth Doctor, joined the resistance to destroy his kind, becoming known as the "good Dalek". (TV: Into the Dalek) Eventually making his home on Villengard, Rusty survived for billions of years into the far future, defending himself as Daleks were repeatedly sent to destroy him. (TV: Twice Upon a Time)

Bronze Daleks were among a diverse range of Daleks who, led by a red Supreme Dalek resided on the rebuilt Skaro where Davros lived, having survived the destruction of the Crucible. (TV: The Magician's Apprentice) One bronze Dalek was killed by, allowing Clara Oswald to temporarily operate its casing so that they could safely navigate the Dalek City. When the Doctor's regeneration energy rejuvenated the discarded Daleks from the sewers, the city-dwelling Daleks were overrun and destroyed. (TV: The Witch’s Familiar)
