Recon Scout Incident

The Recon Scout Incident was the Time Lord designation for the event in which the Thirteenth Doctor confronted the reconstructed Reconnaissance Dalek. (TV: Resolution, PROSE: Dalek Combat Training Manual)

A day to come
Through the extrapolations of the Matrix, the Time War-era Time Lords foresaw the encounter with the Reconnaissance Dalek in the Doctor's personal future, which was recorded in the Dalek Combat Training Manual. They attributed the "remarkable" feat of the Dalek having initially been defeated by primitive humans to it being unprepared for the overwhelming opposition that it faced, anticipating that they would not be so lucky were they to encounter one. (PROSE: Dalek Combat Training Manual)

Prelude
In the 9th century, a Dalek reconnaissance scout came to Earth with the intention of claiming the planet for the Dalek Empire. To defeat the Dalek, an army of former enemies banded together. The army fought "the bloodiest of battles" against the Dalek, suffering massive casualties. Finally, the army managed to trap the Dalek in netting and set its casing on fire, destroying it and "only just" won the battle. However, the Kaled mutant inside was not destroyed in the fire.

Because of the fear the Dalek had instilled in its enemies, the warriors that would become known as the Three Custodians cut the Dalek mutant into three pieces with the plan to bury them at opposite ends of the world and forever guard the burial sites as a precaution to prevent the Dalek from ever returning. Two of the pieces ended up on Anuta Island in the South Pacific and Siberia, Russia. However, while crossing the area that would one day become Sheffield, the third Custodian was killed, preventing him from carrying out his task. The third piece of the Dalek was left with the Custodian's body where he fell and remained there for over a thousand years. (TV: Resolution)

The Incident
Buried by the passage of time, the Lost Custodian was eventually found beneath Sheffield Town Hall and the location became an archeological dig. On New Year's Day 2019, the Lost Custodian's piece of the Kaled mutant was found by archaeologists Lin and Mitch. The third piece of the Kaled was accidentally revived under ultraviolet light, and summoned its other parts. The Dalek subsequently took control of Lin, one of the archaeologists, and used her to gain intelligence, acquire transport, and retrieve its old gunstick. Using remnants of its old shell, combined with spare parts found at Dinkle's farm, Lin built this Dalek a new metal casing.

Letting Lin go, the Dalek went on a rampage (TV: Resolution) in what was dubbed the Recon Scout Incident. (PROSE: Dalek Combat Training Manual) It killed an entire army detachment, and fired a missile into their tank, destroying it. The Dalek was intent on contacting its fleet, and made its way to the Government Communications Headquarters in order to enact its plan. It shut down all power in the UK in the process.

The Dalek was finally stopped by the Thirteenth Doctor, Graham O'Brien, Yasmin Khan, Ryan Sinclair, Mitch, Lin and Aaron using a microwave oven, which melted its new casing. However, the Kaled latched onto Aaron, and demanded transport in the Doctor's TARDIS. The Dalek was finally thwarted when the Thirteenth Doctor jettisoned it into a supernova. The Dalek attempted to take Aaron with it, but Ryan managed to reach his father who fought off the Dalek's control while his son pulled him to safety. (TV: Resolution)

Aftermath
While one account held that Giles of the Preternatural Research Bureau was dispatched to pick up a broken microwave and a battered alien casing in Sheffield on New Year's Day, (PROSE: Preternatural Days) matching the story of how the Recon Dalek's casing was destroyed, (TV: Resolution) the casing actually ended up in the hands of agents of Jack Robertson. Remnants of the Dalek, stuck in the broken and battered casing, were later collected by scientist Leo Rugazzi to create a new lifeform, unknowingly allowing a new race of Daleks to be born. Rugazzi's original new Dalek mutant was the very same Recon Scout, in mind as well as in body; the Doctor observed that "Dalek consciousness can live within the tiniest fragment of their DNA." The Dalek took control of Rugazzi's infrastructure, and made all the necessary orders and purchases to manufacture a vertical farm in Osaka, where it began cloning new Daleks.

During the Kasaavin invasion of early 2020, C maintained MI6's stance not to countenance the possibility of extraterrestrial life, to which the Doctor suggested that he talk to his "mates at GCHQ". (TV: Spyfall)

Using its new army of Defence Drones, the Dalek started an invasion early in 2021, with intent to use Earth as a base to take over the universe. In order to stop it, the Doctor sent the Dalek's original reconnaissance signal into the Time Vortex and summoned Death Squad Daleks, who exterminated the new Daleks for being impure. Teleporting aboard the Dalek saucer via spatial shift, the first clone insisted that it was the last remains of the Recon Scout and that it had completed the original's mission and given its life for the Dalek cause. Although the clone insisted that it could be purified, the Death Squad Daleks exterminated it with their blasters, destroying the Recon Scout once and for all. (TV: Revolution of the Daleks)
