Jörmungandr escaped its cage in the Dark Realm and roared. It was a large serpent dragon with a cobra snake like hood that has high intelligence, much smarter than the average dragon. It is the apex predator of all dragons. It can easily adapt to the environment, have poisonous gas breath, have extremely high stamina, speed, and endurance, and have split jaws combined with incredible jaw strength. It rampaged threw the dark realm, tunneling through. It then stopped when it heard something and looked around on high alert.
