Eight Legs

The Metebelis III Spiders (generally referred to as eight legs) are giant spiders with dangerous psychic powers.



Physical Appearance
The Metebelis III Spiders are large black spiders, generally less then a metre in length. Despite their fearsome appearances, Metebelis III Spiders can't move very quickly and rely on humans for fast transportation. They can create webs like the spiders of Earth, though they aren't sticky and are merely tough. They also fed on living creatures, generally the sheep of Metebelis III, though they preferred humans. (DW: Planet of the Spiders)

Metebelis III Spiders have wide variety of psychic powers, such as telepathy, mind control, teleportation and energy projection. Their teleportation can transport through both time and space, but the further distances require more spider and more concentration. As well, their psychic energy projection can have varying effects based on the force of will of the victim. Metebelis III Spiders can also grasp the backs of humans and allow them to use their psychic powers, becoming invisible in the meantime. (DW: Planet of the Spiders)

History
Far in the future, a spaceship of human colonists crash landed on Metebelis III. Somehow, some spiders from Earth survived as well and were able to make into the mountains. Once there, they were mutated by the Blue Crystals, growing in both size and mental power. Eventually, they started to enslave the humans, forcing them to harvest food and obey their will.

The spiders, led by the Great One, started to gather the Blue Crystals in order to increase their powers and then take over the universe. The final crystal was held by the Doctor on Earth. The spiders were forced to send an expedition back in time to obtain the final Blue Crystal. (DW: Planet of the Spiders)

Trivia

 * All of the spiders encountered were female. Many spiders on Earth have larger females then males, which may mean the males were normal sized and/or less powerful.
