Portal

are magical gateways that usually serves either as a mode of transportation or a means of transformation within. There have been multiple examples of portals seen throughout the series. They can serve as gateways to other worlds or dimensions as seen in and, as methods of quick transportation as seen in , or as a means of transformation in order to explore new places or things as seen in. The use of portals has steadily grown as the series has progressed, and new uses for them have been known to be developed with each new addition to the series.

Overview and Uses
Portals have many uses throughout the series, assisting Link along in his quests against evil by enabling him to meet his needs. At times, he must perform certain tasks to make certain portals available to be used. Typically however there two main uses for portals that have repetitiously been applied throughout the series thus far: transportation and transformation.

Of all potential uses to which portals have been put throughout the series, none has been more prevalent than the ability of transportation. Portals have served as methods of transportation or gateways to permit entry into certain places. This ability has constantly been reused with the development of new games, with portals of varying power and ability acting as methods of quick transportation for Link to places he seeks to reach. They have also been known to be used for transporting Link out of the various dungeons he investigates throughout the series, thus saving the time of having to trek all the way back through the dungeon to reach the exit once the objective has been achieved. Portals have also served as modes of transportation for Link to enter new worlds or dimensions that otherwise would be unreachable by foot or any other mode of transportation for that matter.

Another use for portals that has arisen in the series (though largely on only one occasion) has been to transform Link in some manner from his normal form, or in this case his size. This was first exhibited in, where certain objects found throughout the Overworld turned out to be portals that would allow Link to shrink to the minuscule size of the Minish in order to explore the world the way they were able to. Though they did not really change Link's body in any way in the end, the portals featured at the end of the adult dungeons in and each dungeon in  both caused a physical change for Link that included such things as being encased inside a crystal or transforming into Twilight matter in order to be warped out of the dungeon. It remains to be seen whether any new aspects of the end-dungeon portals will be developed for future games, or whether there will be other transformation features.

In, various portals scattered across the overworld are used to travel between the worlds of Holodrum and Subrosia.

In, Time Portals are able to transport anything anywhere in time. They are opened either when Nayru creates them or when the Tune of Echoes is played using the Harp of Ages.

Four different NaN Portal (Object)s appear in. Three of them, colored blue, red, and green, appear exclusively in NaN Dungeons. They appear after TMC: has reached a certain checkpoint within the TMC:, and serve as a way for him to return to the entrance and maintain his progress. Blue NaN Portal (Object)s appear earlier in NaN Dungeons, with red NaN Portal (Object)s appearing later on, and green NaN Portal (Object)s only appearing after TMC: defeats the TMC: of the TMC:.

The fourth variant of NaN Portal (Object)s is a singular TMC: that appears in TMC: (near TMC:) after TMC: NaN Kinstones with TMC: in TMC:. If TMC: goes through this TMC:, it will transport him to a limited section of the TMC: in the TMC:, where he will have an opportunity to save TMC:.

Other objects in throughout TMC: are called NaN Minish Portals, allowing TMC: to shrink down to the size of the TMC:.

In, Red Portals are created by Zant's evil magic and send Shadow Beasts to fight Link. Once the Shadow Beasts are defeated, the portal then turns blue. Midna can Warp Link to these portals from any location. Zant can also create portals to summon various monsters of Twilight, and it is implied that Ganondorf may use them to teleport. They also bear the Twilight Emblem.

In, Twilight Portals appear as part of Midna's, Twili Midna's, and Zant's attacks. Midna and Twili Midna both conjure yellow Twilight Portals to summon Shadow Wolves to their aid. Zant instead conjures red Twilight Portals to perform a number of attacks, including summoning Zant's Hands and Zant Masks.

Twilight Portals, known as Warp Portals, appear as part of the Twilight Map from the DLC Pack. Red Warp Portals are scattered across the Twilight Map. When a battle square with a red Warp Portal is completed, the Warp Portals on that battle square and somewhere else on the Map turn green. An Ooccoo Item Card can then be used on the green Warp Portal to transport the Warrior to the other battle square, unlocking that square if it had not yet been unlocked.
