PK Teleport is Ninten's Up Special move in SSBTUF. Ninten runs forward and then you can run for 3 more seconds. If Ninten is in the air he can move freely up or down during this time. After the 3 seconds have passed, Ninten will dissapear and reappear with a portal a few feet away. If he is in the air, he becomes helpless.
PK Teleport is a PSI technique that appears in Mother and Earthbound. It is learned by Ninten and Ana in Mother, and by Ness and Poo in Earthbound. Teleport is used to teleport to any place you already visited, but it needs a running start, and you can't collide with anything during this start.
