From loyal heroes to cruel villains, here are the ten most iconic and powerful dragons of the Marvel Universe.
10) Fafnir

Long ago, Fafnir was an evil and greedy king who challenged Odin’s reign. As punishment, the All-Father destroyed Fafnir’s kingdom and sentenced the mad king to death. Managing to escape his punishment, Fafnir found a golden pool that transformed him into a mighty and vengeful dragon. Since then, Thor has battled Fafnir numerous times, often requiring the aid of other Asgardians like the Warriors Three to defeat the dreadful dragon. In one of his most evil acts, Fafnir killed Thor’s close friend, Elif, before he suffered the full wrath of the god of thunder and was reduced to a burning pile of ash.
9) Sadurang

Not only is Sadurang a massive Asgardian dragon, but he is also a skilled sorcerer and pupil of the ruler of the Dark Dimension Dormammu. A greedy dragon, Sadurang has hoarded many treasures in his lair, including the Agamotto’s Eye of Power. During the “War of the Realms” story arc, Malekith recruited the fearsome dragon into his campaign to conquer the Nine Realms. Sadurang would go on to attack Iron Man in New York, where his mere presence caused Stark’s systems to become overloaded and corrupted by magic. Such raw power shows why Sadurang is one of the most feared dragons in all the Nine Realms.
8) Grogg

After being awoken by a several-century-long slumber by Soviet nuclear bomb testing, the giant fire-breathing dragon Grogg went on a rampage before being launched towards Mars in a rocket. The Collector would eventually capture Grogg, only to be freed by Mole Man. The subterranean villain had the dragon attack the Fantastic Four, but Grogg was banished to the Negative Zone. Years later, Grogg returned to Earth and was captured by S.H.I.E.L.D., where he was recruited to become an agent of the Howling Commandos. Since then, Grogg has acted as the team’s mode of transportation, carrying them into dangerous areas.
7) Mr. Lao

Chinese dragons have been revered throughout history for their wisdom and knowledge. One such Lung Dragon, named Mr. Lao, has acted as an advisor to the secret organization, the Atlas Foundation. Centuries ago, Mr. Lao defeated a genie and gained its power but was also cursed to be trapped inside a lamp. In the modern era, Mr. Lao was freed from his prison and now serves as the new head of the Atlas Foundation under the guidance of Jimmy Woo, who offers the young man leadership advice for the superhero team, the Agents of Atlas.
6) Midgard Serpent

The child of Loki, Jormungand, the Midgard Serpent, is a legendary beast that threatens Asgard and Earth. Odin saw the danger the serpent posed and banished him to the depths of Earth’s oceans. Over time, Jormungand would grow to be so massive that he now encircles the entire planet, earning him the title of the Midgard Serpent. Thor and this massive snake have fought each other many times, but their most extraordinary clash is yet to come. It is prophesied that when Ragnarok arrives, the Midgard Serpent and Thor will have a climactic battle that will shake Asgard itself and result in the deaths of both.
5) Grendel

What’s worse than a dragon? A symbiote dragon. Created by Knull, the God of Symbiotes, Grendel is a horrifying monster older than time itself made to kill Celestials. He has invaded Earth on multiple occasions, including during the Viking Age, when he battled Thor. On top of powers, including super-strength, flight, regeneration, and fire breath, Grendel has many other abilities that make him a truly unique and terrifying dragon. Grendel can reanimate the dead and sprout tendrils from his body to ensnare his prey. It’s safe to say that Grendel is a genuinely terrifying dragon.
