Echo of The Lich

The Echo of The Lich is a wraith of The Lich, which was made by The Lich in case he was ever defeated. It is also the final boss of Lich Land.

History
While Ice King and Hunson Abadeer were having their dungeon meeting, The Lich appeared and knocked them out for three weeks, while he built his own dungeon which he called Lich Land. In it, he put a part of himself which he called “The Echo of The Lich”, which would be unleashed upon entering Lich Land.

Years later, Finn, Jake, and Ice King came to Lich Land hoping to destroy whatever’s left by The Lich. Upon entering the dungeon, the Echo invaded their minds putting each of them in a fantasy made from their memories, hoping to put them somewhere they wouldn't want to leave while it summoned enough minions to destroy Ooo. It put Finn in a Fake version of Farmworld with his mom and Farmworld Jake. It put Jake in a world where a Fake Finn is the one to have stretchy powers instead of him. It put Ice King in a dungeon where a Fake Betty was being held.

After being able to escape the illusions, the three confront The Echo, who insults the trio but takes special aim at Ice King who it belittles as a senile old man with no loved ones and will die alone. Ice King ignores these insults and distracts him long enough for Finn to put Jake in its skull and grows so big he shatters it.

Abilities
The Echo of The Lich is a wraith of The Lich, but has somewhat different abilities. For example, The Echo does not have the ability to take over a person’s mind, but instead he has the ability to look into a person’s mind and create and illusionary world that appeals to that person. The only way to get out of the illusion is to show love, which the Lich finds so repulsive that the illusion will cast the person out of itself. On the other hand, if the person does not wish to leave the illusion or the illusion itself is about love, the only way to get out is to make that person face reality and the illusion will shatter.
