Instant Transmission (瞬間移動, Shunkan Idō; lit. "Instantaneous Movement", also translated as "Teleportation") is a technique for traveling long distances instantly. This action is usually accompanied by the user placing his index and middle fingers on his forehead to help him concentrate, though if extra time is taken the technique can be performed without this aid. It was taught to Goku when he was on Planet Yardrat after his deadly battle with Frieza.
Utilizing Instant Transmission causes the user to go into a "Teleportation Zone", and then drop out of it somewhere else by locking onto ki. If two users of Instant Transmission enter the zone they are capable ofinteracting with each other. The teleportation zone is seen in Dragon Ball Z: The Return of Cooler, where Goku and Meta-Cooler both enter the zone and fight each other, it is also briefly seen in Dragon Ball Z: Broly - The Legendary Super Saiyan, where Goku uses it to get to the South Section.
