David Winton was a colonist in the human settlement on the planet Uxarieus in 2472.
Winton was the chief political rival to the leadership of John Robert Ashe, strenuously arguing for the colonists' departure to another, more habitable planet. However, once the forces of the Interplanetary Mining Corporation arrived and threatened to compel the colonists to leave the planet, Winton became fiercely protective of his new home. He led an assault against the IMC ship and argued for a more militaristic response to the threat than Ashe was willing to undertake.
After Ashe sacrificed himself to ensure the colony's survival, Winton became the leader of the survivors. (TV: Colony in Space)
