A Sphere Field (スフィア・フィールド Sufia Fīrudo) is a special field made by high energy in form of giant energy ball originated from the alternative dimensions in the Yu-Gi-Oh! ZEXAL anime. It is stimulated version of parallel worlds with various sorts of coloration, which either encase the "Number" cards or grant various abilities to those who Duel within them.
When Yuma Tsukumo opened the gate to the Astral World, a miniature Sphere Field encasing the "Numbers" appeared, trapping Yuma. It then glowed and suddenly disappeared, hereby spreading the "Numbers" to their world.
Dr. Faker designed his own Sphere Field and began construction of it five years prior to the World Duel Carnival, assisted by Byron Arclight. Upon its completion, Faker used it to absorb the energy of the "Numbers". It was utilized in combination with the strange powers of Hart Tenjo to attack the Astral World.
During the final match of World Duel Carnival, the Sphere Field was generated on top of the Duel Tower for the Duel between Yuma and Vetrix, allowing Faker to gather more energy from the "Numbers" they use. It was treated as a card, which allowed both players to randomly Xyz Summon "Numbers" by using two monsters in their hands of the same Level as Overlay Units. Later on, after Yuma defeated Vetrix, it reacted and revealed its final effect which was to take away all the "Numbers" from their holder and to absorb the Duelists themselves once the Duel was over. Yuma used "ZW - Lightning Blade" to anchor himself and Vetrix in place to prevent this from happening, but Vetrix sacrificed himself to release the souls of his victims. Sphere Field was then teleported itself to basement of Heartland Tower.
In the basement of Heartland Tower, the Sphere Field was plugged into the Sphere Field Cannon along with all "Numbers" collected from Yuma and Vetrix. Faker planned to use Hart to power the Sphere Field Cannon to destroy the Astral World with Yuma & Astral inside. After Kite, Shark, and Tori's interference, Astral undid ZEXAL and ejected Yuma from the Sphere Field in order to save Hart and the Astral World. When Vector took control of Dr. Faker, Hart disabled the Sphere Field Cannon letting Astral and Yuma fuse and defeat Vector which destroyed the Sphere Field and Sphere Field Cannon.
Sphere Field Cannon
The Sphere Field Cannon (スフィア・フィールド砲 Sufia Fīrudo Hō) is a machine created by Dr. Faker to destroy the Astral World, located below Heartland Tower. After the finals of the World Duel Carnival ended, the Sphere Field moved to the cannon, destroying Heartland Tower in the process. A slot within it allows for Hart to integrate with it, with his powers being used with the "Numbers" to power it, using Astral and Yuma as bullets to completely destroy the Astral World. It can launch trash directly into the Astral World via a portal. After the conclusion of the Duel between Yuma, Shark and Kite against Faker, the cannon was destroyed when the room collapsed.
In order to acquire the "Numbers", beings from the Barian World developed Sphere Cubes which generate a red Sphere Field, allowing Barians gather Numbers themselves. Durbe gave three of them to Mizael, one for himself and two for Gilag and Alit. The Sphere Cube projects a Sphere Field in order for the Barians to show their true Barian form as they cannot show it in a low-energy world such as the Earth and such must retain their human form.
