Teleportation

Teleportation is the transfer of matter or energy from one point to another without traversing the physical space between them.

Characteristics
The rate or velocity of the various beings by which they teleport don't seem to vary - a character is there in one instant and gone in the next.

Demons can be forced to appear by summoning them. Angels teleport or fly using their wings.

The only definitive beings that can literally teleport anywhere in the entire universe are God, The Darkness and Death.

Absolute teleporters
These characters can literally teleport anywhere in existence (although they can be caged, and, according to the reaper Billie, nothing can return from The Empty).
 * Death - Death can teleport anywhere he wants.
 * God - God can teleport anywhere he wants.
 * The Darkness - As God's older sister, she can teleport anywhere she wants.

High teleporters
There characters can teleport around the universe; however, Enochian and other spell plastering can prevent specific beings from entering a place. No angel can teleport into or out of Lucifer's cage when the door is shut.
 * Angels (formerly) - Angels can teleport almost anywhere in the universe.
 * Archangels - Archangels can transverse almost anywhere in the universe.
 * Cupids (formerly) - Cupids can teleport almost anywhere in the universe.
 * Deities - Some pagan deities can teleport almost anywhere in the universe.
 * Famine, Pestilence, and War - They can teleport pretty much anywhere they wish.
 * Grigori - Grigori can teleport almost anywhere in the universe. They even kept that ability after the Fall.
 * Reapers - Reapers can transverse almost anywhere they please.
 * Seraphim (formerly) - Seraphim can teleport almost anywhere in the universe.
 * Zanna - Zanna could teleport inside of the Men of Letters bunker. However it should be noted that the Bunker was not locked down at that time.

Average teleporters
These characters can teleport anywhere on Earth.
 * Daeva
 * Demons - Some demons can teleport to and from Earth and Hell easily.

 * Fairies - On Earth, fairies have been shown to be able to teleport from one location to another in the blink of an eye.
 * Ghosts (most are bound to a particular area, but some are free to go anywhere.)
 * Jesse Turner - Jesse can teleport himself anywhere on Earth with a thought.
 * Shojo
