Scarecrow
Home Planet: Earth
Life Form: Animated human product
Info: The Family of Blood used scarecrows as soldiers, animated through "molecular fringe animation", in order to do their bidding. Mainly this was kidnapping local people for them to possess, and to attack.

The scarecrows were neither living creatures or cybernetic in any way. They had no ability to speak, nor any apparent skill with electronics, and were simple servants, bound to do whatever their masters required.
Episodes appeared: Human Nature, Family of Blood

Scribble Creature
Home Planet: Earth
Life Form: Animated Graphite
Info: This animated mass of graphite was created via the power of the Isolus, through a young girl angrily scribbling on a piece of paper. The fact that it attacked Rose suggests that, although it may have no mind or will of its own, it is somehow connected to the Isolus.


Although it floats through the air, it appears to be completely lifeless, simply powered by the Isolus. This connection can be severed by the sonic screwdriver, which renders the scribble creature completely harmless, and returns it to its normal graphite state. Since its merely pencil lead it can rubbed out by an eraser.
Episode appeared: Fear Her

Life Form: Humanoid Feline
Info: The Sisters of Plenitude were cat people, who dressed like nuns and worked in the New Earth Hospital. Driven to desperation at their increasingly ineffective control of diseases, they bred living humans that they tested on to find cures.

Slabs
Home Planet: Unknown
Life Form: Animated life form
Info: Solid leather, animated by rudimentary intelligence, these slave drones always work in pairs. It can be assumed that since they are pure leather, they can take any form, a Plasmavore hiding on Earth sculpted a pair of Slabs into resembling motorbike riders.


A Slab can be destoyed by an overdose of Roentgen radiation from an X-ray machine, presumably it interferes with the rudimentary intelligence rendering the slab completely useless. We have also seen a slab being completely vaporised by a Judoon laser gun.

Living Sun
Home System: Torajii
Life Form: Star
Info: Its creation unknown, this is more than a simple sun. It is described as the Doctor as "alive" and there is evidence of it being able to speak and understand languages, through possessing people and talking through them.


Energy from the Sun was taken in order to fuel a ship, which is what prompted it to begin possessing members of the crew. It seems the Sun was bent on revenge, sabotaging the ship and asking the crew to "burn with me". It seems that the Doctor's superior mind allowed him to fight against its psychic attack and understand the fury of the Sun. Once the fuel, or its "soul" was returned, it allowed the ship and the crew to survive.

Due to the power of the Sun inside of them, the possessed carried some extraordinary abilities, such as a superior tolerance to freezing conditions, and the ability to wield extreme heat and light. As well as this, it seems that the Sun can access the memories of those possessed in order to find out information.

When changed, the pigs have no memory of their past lives, and are less intelligent, simply following orders. They are extremely aggressive and savage creatures. However, they are also vulnerable and have very short lifespans, only lasting up to a few weeks. Post-mutation, Laszlo still retained most of his memory and personality since he managed to escape before the process could be completed.

Plasmavore
Home Planet: Unknown (possibly Mutter's Spiral)
Life Form: Near humanoid
Info: The Plasmavores were a race of blood-sucking near-humans. They were commonly criminals, murdering people across the galaxy. They needed blood to survive as their bodies absorbed a lot of salt. Some Plasmavores made use of Slabs to restrain their victims before killing them.


The fact that they were near-human helped them to hide, as they could blend in with humans on Earth. When they drank Human blood, they could assimilate its properties into their own systems and fool alien scanners (such as the Judoon's) into seeming Human.
Episode appeared: Smith and Jones

Reapers
Home Planet: Outside of time (the vortex)
Life Form: Temporal predators
Info: Reapers are linked to Time itself. They would search out disturbances in time, such as paradoxes, leave the time vortex and "sterilize" the area by devouring everything, with older objects and sentient beings being the tastiest and more interesting.


They engulf their "food" in a flash of light, leaving no traces. Despite these powers, one in the real world, they become material creatures, and can be blocked. They cannot pass through solid objects, but as damage to Time accumulates, it allows them easier entry. The presence of Reapers would seem more common as, since there are no other Time Lords to prevent temporal paradoxes, they happened with more frequency.
Episode appeared: Fathers Day


Robot Spiders
Home Planet: Unknown
Life Form: Robotic
Info: The Spider Robots were used by Lady Cassandra for sabotage and later on for spying. They were transported on board Platform One within small metallic orbs, only emerging when the coast was clear.


On their own they don't seem to be very strong or dangerous, more like simple scouting droids, for small repair work and maintenance. However, they can be formidable in large groups, using their superior numbers to take out unsuspecting life forms. Usually though, they seem to work on their own, using their intelligence rather than strength to murder.

After going on a rampage, Lazarus is seemingly killed. However, he recovered in the ambulance and hid in Southwark Cathedral.
