In the crossover series Star Trek/Green Lantern: The Spectrum War, the return of Nekron in a not-too-distant future results in the complete destruction of the DC Universe,[58] with Hal Jordan and the other members of the original 'new Guardians' the only survivors after Ganthet initiates the 'Last Light' protocol, banishing all surviving ring-wielders to the alternate Star Trek universe, where his corpse is collected by the USS Enterprise.[59] After Hal makes contact with the Enterprise and learns of Nekron's return in this universe, he assists the crew in thwarting the new ring-bearers, as well as dealing with the threats of Atrocitus, Sinestro and Larfleeze. With Nekron defeated, Hal joins the Enterprise in their mission of exploration.[60] In the sequel, Hal leads the Enterprise crew in tracking down the Oa of this universe, culminating in Kirk becoming the first Green Lantern native to the Star Trek universe, accompanying Hal as he prepares to search for this world's version of Krypton.
