Portal Opening[citation needed] is a technique used by Janemba as a defensive and offensive technique, and also messing with realities. It also appears in Dragon Ball GT in order to open a portal between Earth and Hell.


In its GT usages, the technique is used when two users create an interconnecting energy beam to each other, which creates a gate between their two different locations.


Fused Zamas Portals

Fused Zamasu utilizes portals to beat around Goku

In the Dragon Ball Super manga, Fused Zamasu utilizes portals while in combat in order to utilize a variety of attacks.

Hell Fighter 17 and Android 17 use this in order to meet on Earth and merge into Super 17. Their portal also lets other villains escape from Hell.[3] Piccolo and Dende use the technique to get Goku out of Hell to rescue his friends from the mighty Super 17. Piccolo states that this technique is a fusion of the mind between two Namekians. After Goku questions whether or not Piccolo can get him out of Hell, Piccolo contacts Dende at Kami's Lookout to create the interconnecting energy beam to each other, which creates a gate between Hell and Earth after several attempts.[4]
