Evil Guy

The Dark Magician is an evil being that appeared in the episode The Enchiridion. He placed two final challenges for Finn, being destroyed in the process. He told Finn to come with him to his "brain world", where Finn was to fight the (completely evil) Heart Beast and the (neutral) Ant. When Finn escapes from his "brain world", he then kicks Dark Magician in the "nards". He seems to completely evaporate into a cloud of red smoke that rises from his cloak. Like Reaper, he may be a Lich.

Appearance
The Magician's appearance is that of a scytheless reaper, with glowing red eyes and sharp teeth. It has a tattered, gray cloak with a green substance, possibly moss, hanging from it. It also has pale and bony hands as well as gangly arms. Also, a straight shot at his "nards" will kill him. It is possible that he could be based on the Grim Reaper, an entity that represents death.

Trivia

 * He shares a name of a card from Yu-Gi-Oh!, but not the appearance.
 * He is voiced by Mark Hamill, who is best known for playing Luke skywalker in Star Wars.
