~ A description of the Lich's terrifying nature. Still though, he's a powerful and dangerous force that's waiting patiently for someone curious enough to enter his domain and accidentally unlock his magical chains. Luckily, the Lich King was magically sealed away in his castle long ago. It requires exceptional strength and strategy, and knowing Finn and Jake, they'll probably just run up to him screaming battle cries.

Dealing with the Lich King is serious and dangerous business. When he wants something destroyed, he just raises a legion of undead knights, marches in, and obliterates everything in his path. He doesn't give long monologues about how he's going to rule the world, or waste time by sending out evil henchmen. He was voiced by Ron Perlman, who also played Slade in Teen Titans, Xibalba in The Book of Life, Bular in Trollhunters, the High Mage in the 2003 Teenage Mutant Ninja Turtles cartoon series, Warhok in Kim Possible, Stabbington Brothers in Tangled, Dieter Reinhardt in Blade II and Drekk in Men In Black: The Series. He is an ancient undead entity who wants to bring the extinction to all life in the multiverse, as well as the arch-nemesis of Finn the Human. He is the main antagonist of the Cartoon Network series Adventure Time, serving as the main antagonist of Seasons 2, 4, 6, and the Season 5 premiere arc, the final antagonist of its spin-off series Adventure Time: Distant Lands, and the overarching antagonist of every other season. The Lich, also known as the Lich King, is the main antagonist of the Adventure Time franchise. I am the Ceaseless Wheel, the Last Scholar of GOLB. While a mortal world doubts and questions, I know exactly what I am. You've bested me in many worlds, child, but I always return. You are strong, child, but I am beyond strength. We will sail until every light has been extinguished. I will command a great and terrible army. There is only darkness for you, and only death for your people.
