Superman is Earth’s greatest champion. The world’s gain has come from his home planet Krypton. Krypton’s inevitable end has led to Kal-El who was rocketed to Earth as his birth exploded. It has erased all traces of the great civilization of Krypton. Though this is not the case.
In the crossover of Star Trek and DC, Star Trek/Green Lantern: Stranger Worlds, readers get to have a glimpse of an alternate reality where the Lantern Corps have crossed over into Star Trek’s Kelvin timeline. This has led to major changes for Starfleet and the Green Lantern Corps.
Stranger Worlds functions as a sequel to Star Trek/Green Lantern: The Spectrum War miniseries that saw Hal Jordan and other corps. While finding new allies in Kirk and his crew, they have managed to repel the Orange Lantern, Red Lantern, and Sinestro Corps. Because they had no world to return back to. And all Lanterns remained in the Kelvin timeline.
Incorporation of ring technology
The ramifications were explored in Stranger Worlds. There Starfleet incorporated ring technology into the gear. Hal Jordan ended up joining the Enterprise on many missions. Most amazing was the revelation that Star Trek and DC Universe were not dissimilar as they seemed original.
However, OA was actually how the Green Lanterns have remembered it. Though, the version of DC Universe of OA has actually been an established power for a number of years in the Star Trek Universe.
OA was still in its beginning, and the Guardians were still researching with Manhunter robots and timely ring technology. All of this was tossed into unrest when several DC Lanterns merged on this new OA, wishing to assert its Power Battery. Overseeing one of the charges was Kirk’s old adversary Khan, who had been selected to be the new Red Lantern. And we are thankful for his rage.
