the lich

Personality:   The Lich is driven by a rather single-minded goal: to destroy all life. He appears to show little interest in anything that does not further his ambitions towards this dark end. He also has an apparent hatred for all living things, as Princess Bubblegum said that his only desire was to destroy life, and his wish to Prismo was "for the extinction of all life." It has been said that he brings sadness everywhere he goes. In the episode "Wake Up", Prismo implies that the Lich's desire to eliminate all life is so strong that he literally disregards anything else. When the Lich was trapped in the time room, he was motionless and did absolutely nothing until there was a way for him to be free showing that the Lich has absolutely no other focus than to cause mass extinction, and when he cannot do that, he chooses to do nothing at all. This shows that the Lich is barely even a living sentient entity and more like a machine with a built-in goal. Despite this, the Lich is not a mindless murdering psycho that just kills anything he sees, like most hostile monsters. He specifically wants to eradicate all life in existence and seems to understand that simply destroying everything in his immediate vicinity wherever he goes is not the best way to go about that. He instead is a deep planner; given his lack of aging, and lack of most emotions, he is more than happy waiting centuries for the exact right moment to do whatever is necessary in order to further his final goal of total extinction, no matter what he believes is the best course of action for that, even if it means making temporary allies to kill later. His motives to extinguish all life are later revealed across alternate versions of himself in "Casper & Nova" that were in devotion to the ancient cosmic embodiment of chaos: GOLB; whom he openly revered and had dedicate himself to the pursuit of understanding as its titular last scholar. As such, the Lich strove to be its vassal on the physical plane and causing mass extinction in honor of his patron deity. He is viciously cunning and quick to learn from his mistakes. He methodically targets people and things that have proven a problem for him in the past by either destroying them outright such as in the case of the Gauntlet of the Hero or using them as pawns to further his own agenda in the case of Billy to manipulate Finn. As shown in "The Lich", he is highly skilled at deception, as he was able to fool Finn and Jake into helping him while disguised as Billy. At the end of the episode, he tauntingly thanks Finn for opening the portal for him. He is a quick thinker, pretending to be horrified when Finn tried to smash the Enchiridion, even though that would cause the portal to open. The Lich is rather taciturn and speaks only in brief statements. Because he seldom speaks, his words carry great gravity. An example would be when the Lich calls Ice King "a weak fool." In the episode "The Lich", he was able to talk freely with Finn and Jake. In spite of his intractability, he is visibly shocked when Finn survives his fire attack, and he laughs heartily when Finn attacks him with the sweater provided by Princess Bubblegum. He was also visibly confused when Jake altered his wish. He has only raised his voice once: When Finn asked the possessed Princess Bubblegum if everything was all right. He is prone to going off on brief yet impactful monologues, as seen in "Escape From the Citadel", when he tells Finn of the hopelessness of his situation, and in "Gold Stars", when he reveals the true nature of time to the King of Ooo and Toronto. The Lich's most notable flaw is his arrogance and his single-minded nature. In each case, his defeat has been at the hands of opponents towards whom he was derisively dismissive. He laughed at Finn's attempts to stop him and shrugged off the Ice King as a fool, yet it was through the combined efforts of these two individuals that he was dealt a crushing defeat and forced to possess the body of a lowly snail to escape at the end of "Mortal Recoil". After regaining his strength, the Lich manipulates Finn into opening a portal into the heart of the multiverse. Once again, he falls prey to his arrogant and single-minded nature when he ignores Jake grabbing onto him with a dismissive grunt and continues onward towards his final goal rather than dealing with the two stowaway heroes, he is dragging into the portal with him. This oversight later proves to be the undoing of his masterful plan, leaving him stranded in Prismo's time room with his one wish already spent thanks to the two meddling heroes and some friendly help from Prismo. After turning into a humanoid in "Escape From the Citadel", he loses his old personality and gains a new, infantile one. He seems harmless and does what most infants do, such as playing with toys. In addition, he is kinder and tries to be more considerate of others. As of "Gold Stars", the Lich is still revealed to be trapped inside of Sweet P while Sweet P is almost his own person now.
