The Reconnaissance Dalek is a recurring antagonist of the Thirteenth Doctor's era of Doctor Who. It is a specially modified Dalek who arrived on Earth, and tried on several occasions to take over the planet for the Dalek Empire. It was the main antagonist of Resolution and the secondary antagonist of Revolution of the Daleks. Like the majority of the Daleks of the 21st century, it was voiced by Nicholas Briggs, and was physically portrayed by Charlotte Ritchie, as well as Daniel Adegboyega, and Nathan Stewart-Jarrett.
Arrival on Earth
The Reconnaissance Daleks were among the first Daleks to leave Skaro, and it was implied that the Reconnaissance Dalek was the very first to reach Earth. Arriving in England in the 9th century, the Dalek found itself facing an army of humans who were made of different kingdoms, who had banded together to face the greater threat.
While the Dalek caused tremendous losses, the humans "only just" managed to defeat the Dalek, trapping it in netting, and burning the casing. The mutant was split into three, but to ensure it could not return, the three pieces were given to different Custodians, who took their piece of the mutant to different parts of the globe, where them and their descendants would guard it. However, the third Custoadian never made it, as he was killed by an arrow in Yorkshire.
12 centuries later, on 1st January 2019, the third Custodian was dug up by archaeologists Lin and Mitch. The mutant was inadvertently revived by UV light, and the pieces of the Dalek were merged back together. The complete Dalek mutant lurked in the tunnels until it found a host in Lin. At her home, the Dalek informed her that she was his puppet. Controlling Lin, the Dalek mutant forces her to access UNIT's archives so it can learn about Earth's capabilities and fulfil its purpose.
The Reconnaissance Dalek forced Lin to drive her car at over 100 miles to where parts from it's old casing was stored. After being pulled over by the police, the Dalek killed them and took the police car as it's vehicle. As the Thirteenth Doctor tried to scan it, the Dalek interfered, proving it to be a Recon Scout to the Doctor. At MDZ Research, the Dalek killed the security guard and retrieved a Dalek gunstick. The Doctor indirectly confronted it and bought time for the TARDISs systems to be rebooted.
After arriving at a farm, and disposing of the farmer, the Dalek rebuilt it's casing from memory, and relinquished control of Lin. Within it's casing, the Reconnaissance Dalek confronted the Doctor directly, vowing to summon the Dalek fleet to Earth. After a battle with the Army, the Dalek headed for GCHQ to contact the fleet, shutting off all comms power in the UK. At GCHQ, the Doctor and her fam managed to prevent the signal being sent, using a microwave oven to destroy it's primitive casing.
However, the mutant took over Aaron Sinclair, and demanded that the TARDIS take it to the Dalek fleet directly. However, the Dalek was tricked into being taken to a supernova, with a vacuum corridor ready to drag the mutant into space from Aaron's back. However, the Dalek was determined to take Aaron with him, until Ryan managed to save his father, and the Dalek was sucked from the TARDIS into the supernova, being vapourised.
