Oa's Zeta-Beam Teleporter Bay
Based on Adam Strange's technology and theories, Zeta-Beam teleporters are able to transport anyone from one point to another. Oa agreed to house a Zeta-Beam teleprting Bay due to their new found involvement with Earth and using Oa's Sciencells to hold Criminals too dangerous to be kept in any real Human Prison after Hal Jordan and the rest of Earth's Green Lanterns disappeared.
Using these Zeta-Beam Teleporters and through having the right clearance one can teleport themselves to the Batcave, Fortress of Solitude, The Watchtower, Thymescira, Atlantis and Vice-versa. Damage to the Teleporters may cause the beams to go wayward and abandon you between the two points you were travelling rather than going from one to the other. Which is obviously dangerous.
