Blink

Blink is a short range teleport used by Guardians, Fallen and Vex. For Guardians, they are teleported three meters forward, backwards, to the left or right using the corresponding direction on the analogue stick. Not moving the stick will teleport the guardian upwards.

Guardians
The blink ability is usable by Voidwalker Warlocks and Bladedancer Hunters. It replaces the Guardian's other jump abilities. It can be deadly when paired with shotguns. You can confuse the enemy by teleporting towards them and killing them a shotgun blast.

Fallen & Vex
Both Fallen and Vex are equipped with their own version of blink. Only Fallen Captains, Barons, Archons, Kells and Servitors possess a Blink ability. They can actually teleport a lot more than 3 meters, the maximum distance is currently unknown, although it appears to be around 12-16 meters. All Vex units possess two types of teleport, the 12-18m blink, but the Vex also possess a much, much longer range teleport which they use to deploy into battle.

Trivia
All Bladedancers possess a Blink Strike, a powerful melee attack combined with Blink. The Hunter may use it even if he/she has not selected Blink as their jump ability.

From several pieces of armor it is implied Hunters learned to blink from Warlocks.
