Marvel's greatest superhero

Clearly Marvel's greatest and most underrated hero. Make this movie god dammit.

Y Ddraig Goch possesses superhuman strength (lifting 50 tons). He can shift between dragon and human form by will though his transformation into his dragon form drains energy from others within an area of roughly 50 square miles, rendering them unconscious. He can breathe fire in both forms. As dragon he has large, leathery wings for flight.

Ddraig Goch fought the invaders' White Dragon so hard cattle lost their milk and women miscarried. King Ludd eventually trapped the fighting dragons in a pit full of mead in Dinas Emrys in Snowdonia.

...the men of Dolgellau pleaded with Ddraig Goch to help them against the Vikings and delivered women to him as payment (one half before the job, one half after the job was done)... The women of Dolgellau were brave and accepted their fate. The dragon consumed one half of them as was the deal.

When Ddraig Goch flew towards Odin, Thor and Hermod again Thor threw Mjolnir at the dragon, who kept it between his teeth and used Mjolnir's enchantement to always return to Thor, as a way to come down at Thor even faster... Ddraig Goch devoured Rhodri, who tasted even better than the women of Dolgellau.

Ddraig Goch fought at the battle of Rorke's Drift, aiding 150 British soldiers in defending a supply station from 4000 Zulu warriors.

Haunted by the endless killings Ddraig Goch began drinking heavily at pubs and gradually forgot his true identity. As Dave Griffin he violently took control over Cardiff's underworld including drug trafficking, prostitution and protection rackets. He became addicted to his own drugs and killed mercilessly.
