Four Dimensions

"The Four Dimensions" redirects here. For the Yu-Gi-Oh! ARC-V episode titled "The Four Dimensions", see Yu-Gi-Oh! ARC-V - Episode 038.

The world is divided into four dimensions. In them there are four boys with the same face. The dragons they have call for each other. As if seeking out each other...

— The phrase recited before the Japanese opening themes for the Yu-Gi-Oh! ARC-V anime, during the Heartland City arc.

In the Yu-Gi-Oh! ARC-V anime, the universe is composed of four different dimensions, in which each inhabitant uses different Extra Deck Special Summon methods. They consist of the Fusion, Synchro, Xyz, and Standard Dimensions. According to Yuto, the Standard Dimension is in the center of the other three. While the populaces of the Fusion, Synchro and Xyz Dimensions use Fusion, Synchro and Xyz Monsters respectively, the Standard Dimension initially did not have its own unique Special Summon mechanic, with the other methods being taught to students at the Leo Institute of Dueling. Recently, however, an anomaly gave birth to a new Summoning mechanic, the Pendulum Summon.

According to Leo Akaba, the Four Dimensions were once a United World.

Each dimension has its own dragon used by Yuya Sakaki and his counterparts that represent their respective dimension's trademark Summoning mechanic, as well as a bracelet worn by Zuzu Boyle and her counterparts that are visually evocative of them.

Inhabitants by dimension

The huge majority of characters in the anime are residents of the Standard Dimension, therefore their names are too numerous to list.
