|"In a world split into four dimensions, four boys exist, all with the same face. Their dragons call to each other, almost as if seeking one another."|
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.
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.
