The "Doomlord" strip was a "breakout" strip that was extremely popular, even more so than Dan Dare who was Eagle's main attraction. The strip returned in Eagle issue 21, titled "Doomlord II", and was considerably more science fiction in approach. It revealed that "Doomlord" was a generic name for one of many "Servitors" from the planet of Nox, who had taken upon themselves the dread task of species-level eugenics for the common welfare of the galaxy. The rulers of Nox, the Dread Council, had noticed the disappearance of the first Doomlord (or Servitor Zyn) on Earth, and dispatched the novice Servitor Vek to investigate and possibly carry out Zyn's judgement. (Vek's name was however not revealed until the Doomlord III story, the Dread Council mentioning it when sending Servitor Zom to find the supposedly missing Vek.) The second series and subsequent series' were relayed mainly from the alien's point of view whereas the first series had been mainly from the point of view of Howard Harvey.
