Water, Water, Neverwhere!
After burying Dave Rigg, Hercules, Jennifer, and Kevin encounter the Atomic Knights, one of whom has been destroyed and replaced by an energy being in search of the secret of exploding compressed water.
| Appearing1 = **Featured Characters:** * Hercules) **Supporting Characters:** * Kevin) ** Basil) * Jennifer Monroe) * Atomic Knights) **Gardner Grayle) **Douglas Herald) **Bryndon Smith) **Antagonists:** * An energy being, who disguises himself as Bryndon **Other Characters:** * Dr. Skuba) * Giant Dalmatians **Locations:** * Earth-86 ** London *** London Heathrow Airport ** North America *** Durvale *** Lake Ontario **Items:** * Ragun **Vehicles:** * Northrop YB-49
| Notes = * Bryndon Smith apparently dies in this issue; however, this story takes place shortly after the 1986 atomic war; Bryndon appeared alive in 1990 (Strange Adventures Vol 1 132), thus we could conclude that he was only apparently dead and returned under unexplained circumstances. However, in DC Comics Presents Vol 1 57, Gardner Grayle confirms his death. Yet, that was an Earth-86 virtual reality analogue on Grayle's mind. During Convergence, Bryndon is seen alive, but it may be that Telos has extracted Durvale (the Knights' city) from its time before Bryndon's death. Finally, we can see six Atomic Knights in DC Holiday Special 2017 Vol 1 1, but Bryndon, if among them, is unnamed. Then, judge for yourself whether Bryndon died or not. * The presence of Dr. Skuba in this issue, a character from OMAC series, give clues that OMAC may exist in Earth-86 too. * Durvale is located west of Lake Ontario in this issue, which could make it a Canadian city, but Strange Adventures Vol 1 153 establishes it as south from Detroit, what leaves it in the border between USA and Canada. Moreover is mentioned in Atomic Knights' stories that the continents had been remodeled by World War III. In previous Atomic Knights' adventures, Durvale had only a loosely defined location. | Trivia = | Recommended = | Links =
