as he readied himself to battle Umbra alone, "And, in the end, perhaps this was how it was always meant to be..." Umbra was never actually shown in any of the issues. A previously unpublished page on John Byrne's website — finished, colored and lettered -- shows two unidentified characters sneaking through a top security Xlerii holding facility to find the corpse of Calvin Carson in a morgue-like drawer after finding out that Captain Brewster had previously inspected the drawer. Four promotional pages published as the series premiered showed a battle between the original team (presumably circa 1970, as Doc Danger was still recognizably human but his cranium had visibly expanded in both height and girth) and aliens (not Xlerii, which is why Calvin did not know of Xlerii) aboard one of their spaceships. Nazi supervillain Golgotha was a recurring adversary of the team, although he appeared only in one flashback. He appears to be a cyborg with a mechanical left arm and his head is a bare skull underneath a transparent dome. Golgotha was the arch-enemy of Torch of Liberty and Doc Danger mentions that he himself and Golgotha had come into conflict in 1944. He is mentioned in John Byrne's timeline of that universe as being fought and killed after World War II. He was resurrected in 1965, battled Danger Unlimited thereafter and later killed in battle by Calvin Carson after murdering Calvin's wife. Ultroid is another villain mentioned in the timeline but not revealed within the series.
