Eight Legs
The Eight Legs were giant spiders with psychic powers.
Characteristics
Physical characteristics
The Eight Legs were black spiders, generally less then a metre in length, though the Great One achieved a much larger size. The Eight Legs relied on Human mounts for transport (see below). The Eight Legs could create webs like the spiders of Earth, though they were not sticky and are merely tough. They also fed on the flesh of living creatures, generally the sheep of Metebelis III, though they preferred Human meat. (DW: Planet of the Spiders)
Powers and abilities
The Eight Legs could speak through telepathy. They could discharge psychic energey. They could teleport through both time and space. To teleport further distances required more spiders to focus their wills.
They could ride on the backs of Humans, turn invisible and possess the Human who could act as a vessel for the Eight Leg's power. They could, for example, project psychic energy blasts, the strength of which varied according to the strength of the victim. (DW: Planet of the Spiders)
History
A starship of human colonists crash landed on Metebelis III. 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. They developed a matriarchal society, based around physically enormous Great One.
The final crystal was held by the Doctor on Earth. The spiders then sent to an expedition back in time to obtain the final Blue Crystal. (DW: Planet of the Spiders)
