What is the jutsu that ninjas use to appear/disappear instantly?


Some users of the jutsu are Kakashi, Gai, Genma, Kabuto, etc. It can often be
seen when Anbu members are dismissed.




The most common one I know of and I think you are talking about is the [Body
Flicker Technique](http://naruto.wikia.com/wiki/Body_Flicker_Technique) (also
known as Teleportation Jutsu, or _Shunshin no Jutsu_ ).

> To an observer, it appears as if the user has teleported. A puff of smoke is

> The amount of chakra required depends on the overall distance and elevation
