The Master altered TOMTIT to act as a time travel device (much like a time scoop) and pick up elements of Earth's military history to fight against UNIT when they attempted to remove him from his base of operations. Through repeated use, he summoned the Chronovore known as Kronos and an Atlantean named Krasis. (TV: The Time Monster) Stuart Hyde would later utilise TOMTIT in the TITAN Array. (PROSE: The Quantum Archangel)
