Portal Opening

is a technique used by many fighters to manipulate reality in order to suit their use.
==Overview==
Most users create small, combat-oriented portals in order to catch their opponent off guard or evade incoming attacks.
In Dragon Ball GT, two users can create a gate between worlds by creating an interconnecting energy beam to each other. 
==Usage==
In the Garlic Jr. Saga, Super Garlic Jr. opens a portal to the Dead Zone again to defeat Gohan, Krillin, and Piccolo. However, Gohan destroys the Makyo Star, which is the source of Garlic Jr's power and is pulled back into the void again.
The Sir Warps act as transit points that allow users to freely travel between each location.
In the "Future" Trunks Saga of Dragon Ball Super, Fused Zamasu utilizes portals while in combat in order to utilize a variety of attacks.
In the of Universe Survival Saga of Dragon Ball Super, the Grand Minister utilizes portals to warp from one realm to another realm. During the Tournament of Power Agnilasa can create portals like Fused Zamasu and Janemba as part of his Subspace Punch technique.
In the Galactic Patrol Prisoner Saga, Seven-Three kills several members of a species that possess the ability to create "Warp Portals" and copies this ability from one of them, using it to get himself, Shimorekka, and Yunba to Earth. He then uses the ability to get behind Piccolo to copy his abilities, and one more time to get himself and his allies back to Moro.
In Dragon Ball GT, 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.
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 the Lookout to create the interconnecting energy beam to each other, which creates a gate between Hell and Earth after several attempts.
In the Supreme Kai of Time Saga of Super Dragon Ball Heroes, the former Supreme Kai of Time Aeos is capable of opening portals to remove attacks from the local space-time which she uses to stop the Future Warrior in Black and Super Saiyan God Xeno Trunks' attacks.
==Film Appearances==
In Dragon Ball Z: Dead Zone, Super Garlic Jr. opens a portal to another dimension called the Dead Zone to pull Goku and the others into it. However, he gets knocked into it by an enraged Gohan.
In Dragon Ball Z: Fusion Reborn, Janemba is seen as a primary user of portals, for both defensive and offensive purposes.
In Dragon Ball Super: Broly, the Energy Clash between Super Saiyan Gogeta's Super Kamehameha and Super Saiyan C-type Broly's Gigantic Omegastorm was so powerful that it shattered the boundaries of time and space, causing the two Super Saiyans to be transported to a Dimension of Strange Swirling Lights. It should be noted that the Energy Clash functioned in a manner similar to how Piccolo and Dende performed Portal Opening in Dragon Ball GT, though in the case of the film it was an unintended side effect of the sheer power generated by the energy clash.
