Synopsis for Hyper-Tension! Part Two, "Superboy of (Two) Infinite Worlds"
His first jump through Hypertime sent Superboy right into the Batcave where he is attacked by the Superboy of this reality who also seems to be Batman's sidekick. Suddenly, Knockout breaks into the cave. Calling Batman and Superboy genetix traitors she immediately attacks as well. The power of her blows activates the hyperjacket which transports Superboy into the next reality.
This repeats itself through different realities. Superboy meets several versions of himself and an energy impact sends him through Hypertime again and again. In his final stop, he crashes to the ground like a meteor and is knocked out with a fried hyperjacket on. When he awakes, he gets into a fight with Krypto the Superdog who belongs to the Superboy of this reality. Interestingly, these two Superboys already know each other as a result of Zero Hour. Both fly to a farm where Kon-El meets Jonathan and Martha Kent. He never knew Superman had a secret identity, but now Superboy deducts the Superman he knows is actually Clark Kent. While the Superboys talk to each other a little longer, a man called Black Zero arrives in this reality and he attacks Krypto ...

Notes
- This is the first story to suggest a relation between the Zero Hour event and Hypertime.
- The events of Flashpoint Beyond #5 in the Post-Flashpoint continuity will acknowledge it, explaining that the event was the first bridge between the two halves– Hypertime and Multiverse/"Omniverse"– of the Divine Continuum.
- The Superboy that helps Kon-El in this issue is the same he met in Superboy (Volume 4) #8 during Zero Hour: Crisis in Time!. The events of this story confirms that he hails from an Hypertime version of Earth-One.
- The alternate Earth-One was glimpsed throughout The Kingdom storyline and Superboy (Volume 4) #60.
- This story confirms that Karkan's "Imaginary Story" from Superboy #183 and the Elseworlds story Elseworld's Finest: Supergirl & Batgirl #1 are set in Hypertime realities.
- Like the universe shown in The Kingdom #2, their designations are eventually revealed in Crisis on Infinite Earths: The Compendium.
- The setting of Elseworld's Finest: Supergirl & Batgirl #1 being an Hypertimeline was already implied in the previous issue, as both Batgirl and Supergirl appeared as Hypertime visions to Wonder Woman.
- The cameo of Kal and Jamie Ollson from the Dark Knight of the Round Table universe is set during the events of Superman: Kal.
