"Supreme King Dragon" (Japanese: () (おう) (けん) (りゅう) , Haōkenryū, lit. "Supreme King Servant Dragon"), is an archetype of DARK Dragon monsters used by Z-ARC in Yu-Gi-Oh! ARC-V. It is a sub-archetype of the "Supreme King" archetype.

With the exception of "Darkwurm", "Supreme King Dragon" monsters appear to be corrupted versions of the Four Dimension Dragons, characterized by having glowing green bands with orange blotches running over their bodies.

In the English Dub, it is stated by Z-ARC that the dragons' unnaturally easy Summoning Condition is the result of his hardworking to take the duel to the next level per the demand of his audiences back in the Original Dimension.
