Basilisk

Wyvern King Basilisk, also known as simply Basilisk, is a Class 5 Wyvern Beast. Compared to other Wyverns, Basilisk is far larger and more powerful, and is in fact the largest living specimen of the Wyvern species discovered, granting it its title of "Wyvern King". Due to differences such as having charcoal black scales as opposed to the usual red, blue, silver or brass scales found on most other Wyvern subspecies, as well as being far larger and allegedly living 100 years in excess of the typical Wyvern's lifespan, it is believed that Basilisk is actually one of the last, if not the last survivng member of a previously undiscovered Wyvern subspecies.
