Black Direwolf (黒牙狼族 kokugarou-zoku, lit. "Black Fanged Wolf Tribe") is an evolution to a regular Direwolf. If they evolved in a more magic-oriented fashion, their fur would turn black.
In volcanic regions, direwolves would evolve with a fire element and become red direwolves. Near bodies of water, you would find blue direwolves. In the forests would be green direwolves. In other words, adopting elements was a fairly common evolutionary pattern for Direwolves.
These wolves were apparently a notorious threat to any nearby humans and humanoids.
- The coats of the Tempest Wolves are black as well but with a uniquely colored purple sheen.
