The Dimension Dragons

In a world split into dimensions, People exist, all with the same fate. Their dragons call to each other, almost as if seeking one another.

The Dimension Dragons were originally 20 dragons owned by Z-arc. Originally these where all Main Deck monsters but due to Z-arc's will the 20 grew stronger and became the Dimension Dragons. Later due to Z-arc's rage they evolved into the Supreme Kings. Each Dragon has multiple forms depending on what made it evolve. 2 or more upgraded versions, showing the potential of evolving without the need of Z-arc, 1 Supreme King version if Z-arc was involved, 2 Odd-Eyes Versions showing a purified form of the Supreme Kings and their more localized power, 1 Dimensional version showing how particular people would fuse their aces with the dragons and 1 "Incarnation" version. The incarnation version is supposed to be the strongest version of the card, evolving by something in their dimension
