Spektrillas

Spektrillas are a fictional alien species from the Doctor Who television series. They first appeared in the 1985 serial "The Two Doctors". Spektrillas are a parasitic species that can take on the form of their hosts. They are known for their intelligence and their ability to manipulate others. Their home planet is believed to be a dying world, which has driven them to seek out new planets and hosts to survive.

The Spektrillas are characterized by their elongated, pale limbs and their ability to extrude tendrils from their bodies. In their natural form, they appear somewhat insectoid. Their parasitic nature means they often operate from within a host, subtly influencing events to their advantage. This makes them a particularly insidious threat, as their presence may not be immediately obvious. Their ultimate goal is survival, and they are willing to go to extreme lengths to achieve it. In "The Two Doctors," they were attempting to drain the life force from humans and other beings to sustain themselves. Their appearance in the series highlighted themes of survival, deception, and the consequences of desperation.
