Now, I’m not sure the precise details regarding how the gods of New Genesis and Apokolips call forth the Boom Tube, the mode of transportation, a temporary interdimensional bridge, linking the two worlds together and each to Earth. Orion simply says, “It stems from the waves of the mind!” Going between the planets in instantaneous fashion, there’s also the pre-Boom Tube “Matter Threshold” and “Dimension Threshold,” and Big Barda’s “Mega-Rod” (“It’s the latest from ordnance!! Better than the Boom Tube!“).
But it seems those X-Element fueled modes of instantaneous transport aren’t used to get from one place to another on our home planet. But Star Trek-like teleportation on Earth can be achieved via phasing circuits sewn into clothing (as so with the Female Furies in “Funky Flashman”) or phasing with The Forever People’s Super-Cycle or when the Super-Kids use Mother Box, as they did in the last issue of their title. There’s also the little-used method of the Tele-Ray, a mode only seen in this second issue of The New Gods, I believe.
After Darkseid and Brola break into Dave Lincoln’s apartment and their unsuccessful confrontation with Orion, the two Apokolips denizens suddenly vanish, Brola in mid-air over a Metropolis street! Surveying the avenue below through a huge gaping hole now aerating the Lincoln abode, Orion says, “Darkseid moves as no one on Earth does! His machines are legion and infinitely precise! It is evident that Brola never completed that fall — that Darkseid snatched him by Tele-Ray!”
And the second — and final — reference to the Tele-Ray in the series is when, with a ZZZTTT, Darkseid and his “fighting arm,” Brola, appear by Tele-Ray in “one of the secret bases established beneath the city.”
