The 6 Dragon Emperors are direct creations of the Six Astral Gods and share the same elements as their creators. 

They have more Magic power than any living being thus they have at least two Magic attributes. 

The only beings that surpass them are their creators.

 Just one Dragon Emperor has enough Magic power to destroy continents, but with all 6 combined, they have enough magic power to destroy the world.
