The Zeroth Dragons are weapons of mass destruction born from the Dragon Deity of Destruction, Gyze. The apostles of Gyze plan to use these dragons to revive him, bringing Planet Cray into an era of destruction and chaos by trying to defeat the Messiah. They also share the symbol called "Mark of Gyze" on or around their bodies or weapons. In the anime, they are used by Gyze's Apostles, each of them corresponding to the respective nation of their decks.
They are cards without a printed clan, but a nation's name instead, which makes them belong to the clans from that nation. Likewise, they have a new mechanic called Ultimate Stride, which allows them to Stride upon any clan of their respective nation. They also have their own nation-specific foiling in their respective booster sets, as well as being released purely in ZR rarity.
Zeroth Dragons, the Destruction Weapons Spawned by Gyze
The Dragon Deity of Destruction, "Gyze", had once completely dominated the land of Cray, and spawned these destruction weapons by fusing spirits of the planet with his own power. They are pseudo-"Transcendent Lifeforms", and they resemble formless spirits more than common lifeforms. First, Gyze drove the gigantic wedge "Dragon Bone of Destruction" into lands abundant of spirits. The dragon bone absorbed all the spirits of the place and formed dragon bodies according to the nature of the lands. The six "Zeroth Dragons" spawned by this method were named "Distant Sea", "Inferno", "Death Garden", "End of the World", "Destroy Star" and "Zenith Peak". Though the Zeroth Dragons had decimated numerous warriors of light with their powers beyond mens' wisdom, they were eventually suppressed by the unyielding warriors, and were put to an end together with Gyze by Messiah. Nonetheless, the cores of the Zeroth Dragons, the dragon bones, host Gyze's immense grudge, and even Messiah could not completely nullify it. The optimal measure was to seal the dragon bones in a planet's innermost core so that none could approach it. However, Gyze's dominion had depleted Cray and the planet could not bear to seal the dragon bones. Messiah had no alternative but to seal the dragon bones in another planet with brimming lifeforce.
