Lunagaron

A Fanged Wyvern with distinctive azure scales. Although normally quadrupedal, it can change its body composition by inhibiting its thermoregulatory organs to increase heat and enlarge muscles.

Four Legs or Two: This monster's behavior varies with its stance. When on all fours, it swiftly charges to bite prey. When on its hind legs, it attacks with its forelegs and uses its ferocious claws to tear prey apart.

Cobalt Core: Its abdomen is inset with a glowing, cobalt-blue core that radiates intensely cold air. Some believe this is caused by special body fluids circulating through and acting as a coolant.
