Lord Maliss

Lord Maliss (simply known as Maliss) is the main antagonist in the 1990 animated fantasy film Happily Ever After. After arriving at his sister's castle, he learns about her fate. Enraged, he vows revenge against Snow White and her Prince. He also has the power to turn himself into a dragon.

He was voiced by Malcolm McDowell, who is best known for other villains such as Alex in A Clockwork Orange and Dr. Calico in Bolt.

History
After arriving at the Evil Queen's castle, Lord Maliss learned the news of his sister's recent death, later then takes control of the Queen's castle and her demonic minions, twists the land into the Realm of Doom before he left and began hunting down Snow White.

After transforming Prince into a tiny and feeble man, Lord Maliss resumes in hunting Snow White, who has fled to the Seven Dwarves' cottage to find their female cousins, the Seven Dwarfelles, who have taken up residence and attempt to help Snow White find her prince who turns out to be the "Shadow Man".

After a failed attempt by Maliss's wolves to capture Snow White, he does the job himself and takes Snow White to his castle newly dubbed "Palace of Malice" where Snow White wakes up to the presence of the Prince who then takes her through a secret passage.

Snow White is taken to a secret graveyard at the castle, where the "Prince" reveals himself to be Maliss in disguise.

As he is about to place a cape that will petrify her, Maliss is attacked by the Shadow Man, whom he defeats and seemingly killed. Then, he again tries to petrify Snow White, only to be stopped and attacked by the Dwarfelles. However, they fail, and Maliss throws the petrifying cloak on all of them except Thunderella, who gains control of her powers and subdues him while Snow White grabs the cloak and throws it on him. Maliss, from here, is forcibly transformed into a larger version of his dragon from (except for his head) and completely turned to stone for eternity.
