Appearance: The Woman Who Fell To Earth

In order to become the race’s next leader, the Stenza must travel 5000 galaxies to planet Earth and hunt their selected human trophy in a ritual they call ‘The Ritual of the Stenza’. The Stenza have very cold skin and can kill humans with a touch of their hands, freezing them to death.

A Stenza warrior known as T’zim-Sha (or Tim Shaw as the Doctor called him) came to Sheffield to locate and kill his selected target, Karl Wright. He arrived to Earth in a transport pod. Like his skin, this too was cold to the touch. He also arrived with a Gathering Coil, half-organic, half-machine, which he used to help locate his trophy. Beneath his removable face plate, dozens of teeth were grafted to his face; each tooth taken from a victim, representing a conquest.

Appearance: The Ghost Monument

The Remnants looked like a harmless pile of rags that lay dormant until night time, where they lay in wait to ambush the Doctor and her friends. They are made from a high-density polyfibre, can sense fear and blood and will squeeze you to death – like a Boa Constrictor.

Appearance: Rosa

Krasko travelled from the future to Alabama using a vortex manipulator. One of the devices he bought back from the future was a weapon that could displace things in time.

Due to him being a former prisoner of Stormcage, he was implanted with a neural restrictor in his brain - which prevented him from hurting anyone. He targeted Rosa Parks, whose actions kick-started the civil rights movement.

Appearance: Arachnids In The UK

There are around 45,000 species of Spiders on Earth. Spiders taste and smell through their feet. They give out pheromones and really like grime music.

They aren’t responsible for what has happened to them. The spiders were just doing what came naturally. The Doctor taught her friends to respect the living creatures and preserve life wherever possible.

Appearance: The Tsuranga Conundrum

The Pting is a small but mighty alien with sharp teeth, toxic skin, and can move faster than Usain Bolt.The creature is impossible to keep captive and can survive in the vacuum of space.

The Doctor and friends got separated from the TARDIS and the Pting was eating the spaceship they were on – The Tsuranga.The Pting wasn’t malicious, but its natural behaviour would have caused the death of everyone on board the Tsuranga.

Appearance: Demons Of The Punjab

The Thijarians who met the Doctor were survivors of the destruction of their civilisation. They were not there at the end, to grieve of honour them.

The Thijiarians did not come to Earth to kill. They watch over the victims of the fighting, and bore witness to those who died alone.

Appearance: Kerblam!

The Postmen worked for a company called Kerblam – the biggest retailer in the galaxy. It picked, packed and delivered anything you could want.

The warehouse robots were called teammates, who were supposed to support the organic members of the team…but people were going missing.

The Postmen were getting ready to deliver death throughout the galaxy. But the Doctor had a solution and it was soon signed sealed and delivered.

Appearance: The Witchfinders

In seventeenth century Lancashire, there were literal witch-hunts going on in the village of Bilehurst Cragg. One of the reasons for that was because the Morax were incarcerated inside nearby Pendle hill.

Bilehurst means ‘sacred tree on a hill’. The tree in question was the lock that kept the Morax secure. When the tree was cut down the Morax started to ooze out and take over bodies – living or dead.

Appearance: It Takes You Away

Appearance: The Battle of Ranskoor Av Kolos

Appearance: Resolution

It landed here way back in the 9th century. After a long, deadly battle, The Dalek was defeated. It’s casing was destroyed; the creature inside was cut into three pieces so it could never reform.

Two were successfully transported away and guarded by the order of the custodians. But one piece was left behind.

It stayed in Sheffield, where it was found 12 centuries later and was accidentally woken up.

You would think a squiddy thing like that couldn’t get far. But turns out it could hitch a ride on humans. It built it’s own casing from spare parts and bits of it’s original outer shell.
