King Einon

King Einon is the main antagonist of the 1996 action/adventure/fantasy movie, Dragonheart. He was played by David Thewlis.

History
In the year 984, Einon's father is killed by a peasant rebellion and young prince is being educated by his mentor Bowen. Once when Bowen is instructing him, Einon is mortally wounded by a peasant girl, Kara. His mother takes him to a dragon, Draco, who agrees to give Einon a piece of his own heart, if he promises to rule with justice and virtue.

However, Einon becomes just as evil as his father, by forcing the rebels to rebuild the castle and torturing them for amusement. Bowen believes the dragon has corrupted his heart and swears vengeance.

12 years later, King Einon has successfully rebuilt the castle and reveals to Bowen that he's been evil along and lied about his oaths. His mother hires a group of dragon-slayers to capture the dragon, in hope of killing him.

King Einon is on to her and kills her for intending to "make a mistake made years ago, when she saved a creature not worth saving." Bowen and King Einon engage in a last fight. Draco begs Bowen to kill him, as it's the only way to officially end King Einon. Reluctantly he does so, killing King Einon.
