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)
