Reaktoners

Reaktoners are a fictional group appearing in the science fiction television series Doctor Who. They were introduced in the 2007 episode "Gridlock". Reaktoners are a sentient species native to the planet New Earth. They are characterized by their highly resilient and durable physiology, allowing them to survive extreme conditions and possess great physical strength. Their appearance is often described as imposing, with tough, leathery skin and a formidable build.

The Reaktoners are primarily depicted as a working-class population on New Earth. They inhabit the lower levels of the city of New New York, a densely populated metropolis characterized by its multi-layered structure and constant vehicular traffic. In "Gridlock," the Reaktoners are shown to be oppressed by the ruling elite, a society that utilizes their strength and resilience for labor and as a means of social control. They are subject to harsh living conditions and are largely ignored by the upper classes.

The species' resilience is a key aspect of their nature. It is implied that their biology has adapted to the harsh environment of New Earth, making them exceptionally tough. Despite their formidable nature, the Reaktoners in "Gridlock" are portrayed with a degree of empathy, highlighting their struggle for survival and recognition. The Doctor's interaction with them in the episode serves to expose the injustices they face and to advocate for their rights. Their role in the narrative underscores themes of social inequality and the treatment of marginalized populations within a futuristic society.
