Mister Terrific stumbles upon Simon Stagg's plot to open a portal to the Dark Multiverse with Metamorpho transmutated to Nth Metal. While trying to get Simon Stagg to close the portal with the help of Plastic Man, Mister Terrific is sucked in to the portal with Plastic Man and Metamorpho as Plastic Man shields them from the Dark Multiverse energy. Upon arriving on a lifeless world, they encounter Phantom Girl who has been trapped in her intangible form and had no knowledge of sending a signal. When the four of them find a computer in the gut of a dead giant creature, they are greeted by a hologram of Tom Strong who states that they are needed to save the universe. Mister Terrific, Plastic Man, and Metamorpho learn from Phantom Girl that she was stuck in intangible form since she was a child. After the four of them made it back to their world, Mister Terrific tries to leave the three of them at Simon Stagg's compound only to be drawn back to them. Due to the effects of the Dark Multiverse energy, Mister Terrific concludes that they can't go their separate ways due to this bond. Though Mister Terrific was able to come up with a compromise with Simon Stagg by investigating the bond at his facility. This leads to Mister Terrific to find the Tom Strong that sent left the message and find out how to get untethered by the dark energy.
