Miðgarðsormr is one of the Five Great Dragon Kings. Known as the Sleeping Dragon, Dragon of the End, Midgard Serpent and World Serpent, he is the largest dragon in existence, with Apophis and Great Red being second and third in terms of size. He is also the second child of Loki and the younger brother of Fenrir.


Midgardsormr is a grey Eastern dragon with an enormous body measuring around 500-600 meters in length, well over five times the length of Great Red's body.


He is an extremely lazy dragon, spending most of his time asleep. He is also quite dismissive towards others including his father and brother, claiming that they are meaningless existences to him. When conversing with people, Miðgarðsormr speaks with a well-mannered, very laid-back tone of voice, occasionally falling asleep in mid-conversation, yet very wise enough to give advice to others.

Interestingly enough however is that Miðgarðsormr doesn't seem to mind waking up when there is something interesting going on, even going as far as saying to wake him up again if something happens.


Miðgarðsormr (or Jörmungandr) is the middle child of the Giantess Angrboða and the god Loki. Eventually, he grew so large that he was able to surround the earth and grasp it with his own tail which is what gave him the nickname "World Serpent". When he lets go, the world will end, earning him his second nickname "Dragon of the End". Though immensely powerful, his colossal size and laziness left the gods in Asgard scratching their heads and they decided to have him sleep at the bottom of the ocean until Ragnarok, thus earning him his third nickname "Sleeping Dragon". In spite of this, he has been known to surface on occasions (though he was still asleep when this happened). During one of these instances, he was taken care of by the local Dökkálfar (Dark-Elves) and Svartálfar (Dwarves).
