Teleporter

A Teleporter, or Transporter, is a technological device which enables the ability to transport objects over great distances instantaneously.

In some cases the physical object is scanned or disassembled at the point of departure and transmitted over a distance to be reassembled at the point of arrival. In other cases, such as "window teleporters", the technology creates a "spatial remapping" whereby a distant location is remapped to be accessible simply by walking through a "window" or "wall" produced by the teleporter. Another instance makes use of the wormhole theory where a device creates a fold or bridge in physical space to shorten travel time between locations.

In-game Involvement
In order to travel to either the JLA Watchtower or the Hall of Doom, both Hero and Villain factions use teleporters as their means to provide access to the locations while keeping the locations effectively secluded. Teleportation is also used by the factions to send their members to required locations.

Trivia

 * Teleportation is a common ability for Magic users such as Raven, Zatanna or Circe where, through the use of arcane munipulation, they can acheive the same results as a teleportation device or science.
