Dragon Cubes

The Dragon Cubes are known to be the fragments of the Tenkai Dragon. After being defeated, it was split into five cubes that were scattered across planet Quarton. When the five cubes are placed on the Dragon's Nest, they are combined into one giant cube that can only be opened with either of the two Dragon Keys.

Colors
The five Dragon Cube came as the same colors of the Tenkai Knights.
 * Green = Valorn
