The protoss have spent thousands of years studying the nature of time and space and as a result, their ability to manipulate it far exceeds that of other races. Arbiters could weaken space-time, tearing rifts in the fabric of space-time, creating a vortex linking another location to the Arbiter's location, warp prisms are able to perform a similar ability through the psionic matrix. In addition, teleportation mechanisms are built into power suits and light armor suits. When a protoss wearing one of these suits nears death, they disappear in a flash of bright light, and are teleported to safety. Primitive and superstitious civilizations have attributed this to supernatural causes. These mechanisms can also be activated manually.
Stalkers are also able to blink—essentially short-range teleportation. Some dark templar also have an ability similar to the stalkers' blink. Adepts are able to teleport using a form of psionic transfer.
Terran teleportation fields were invented by Transmatter Inc. Although not as advanced as protoss teleportation technology, terran teleportation devices are able to quickly move living organisms and objects short distances within structures and science vessels via teleportation pads.
Teleporting a solid object into another solid object can result in a "telefrag".
Transmatter made several attempts to improve on the technology, but they were all failures. Another terran attempt at a teleportation system was the MH-232 Teleportation system, but there was a terrible accident and it malfunctioned. There was a valiant attempt to manually control the teleportation matrix without the automated computer system, but it eventually failed.
In contrast, the Kimeran Pirates had an advanced teleportation system aboard their ship, the Kimera, which didn't require a fixed piece of technology to transport people onto and off the ship. However, the technology required accurate positioning information which came from transponders. If those were knocked off-line, the teleportation system could not be used. By the End War, terran engineers had devised a teleportation system for the Minotaur-class battlecruiser, allowing it to make tactical jumps across great distances.
In the original StarCraft, zealots, bengalaas, and kakarus all used the same blue flash animation upon death. In the case of zealots, this has since been explained as being from their teleportation mechanism.
