They can blend into their surroundings, can teleport, are extremely fast and agile, and may not have tough scales, but with their their uniforms, they are near impossible to bite or scratch.

History
Blood Dragons killed the Star Dragons, Fire Dragons and almost killed the Night Dragons and Frost Dragons. They also murder and steal from the tide and water dragons, who can do nothing but try to prevent it from happening, because they wish to remain anonymous and when dragons try to find out more, they either are reported missing, found dead or come back insane.
