Other alternate timelines[]

These events took place in a timeline in which Earth had formed a system of world government known as the World Zone Authority by the early 21st century.

  • 16 August - On Earth, the sinking of a holiday liner is reported in a newspaper. Many of the passengers are feared lost. (DW: "The Enemy of the World")
  • Having previously convinced them a nuclear war had been taking place for the past four years, Salamander takes a member of the group of people held in the atomic shelter underneath the research station at Kanowa onto the surface. This would be the last time he would do this before their discovery of his deception in 2018. (DW: "The Enemy of the World")


  • As per "The Enemy of the World", Earth has formed a world government called the World Zone Authority by 2018. This system is indicated to have been in existence for some time, with the World Zone Authority also being seen to be based in the United Nations building in New York City. This is contradicted by all other stories set in the early 21st century. Among them is "The Power of Three", which indicates that the United Nations and national governments are in existence as late as 2018. Due to the nature of time travel later established in the program, it is possible that this story and the events leading up to this version of history took place in an alternate timeline.
