The Lich (character)

The Lich King is a villain in Adventure Time. He was first alluded to in the early Adventure Time series pitch, and was the only other character described in those documents in addition to the main six (Finn, Jake, Princess Bubblegum, Lady Rainicorn, Ice King and Marceline). He has no appearances in Season 1 except for the last episode "His Hero." Pen has stated that he will have a far more prominent role in Season 2. At the moment, little is known about him except that the legendary hero Billy once fought and defeated him. The pitch document also states he's been imprisoned within his castle. The Lich King is supposed to be the most powerful character in Adventure Time, on one of Pen Ward's blogs he apparently will make Ice King and Marceline 'run for the hills'. According to the pitch document, he doesn't go straight into battle like the Ice King, but instead uses a legion of undead skeletal knights to fight his battles. He will be unleashed into the Land of Ooo from his castle later in Season 2, in the episode Mortal Recoil.

Appearance
His first design had a more flattened look with large eyes and different-looking horns. The new design has thin lips peeled back, revealing his teeth. He also has curled horns, opposing the original design, where they pointed downwards.
