MacTaggart

MacTaggart was one of the human colonists of Trodos. Envious of others and longing for power, he constructed the Trods to achieve his goals, but the Trods eventually turned against him as well and shot him. After the First Doctor deactivated the Trods, he discovered the fatally injured MacTaggart, who told him his story, then died. (TVC: The Trodos Tyranny)
