DEATH BATTLE: Aku VS The Lich

Samurai Jack vs Adventure Time

Connections:

Both are primordial entities born from evil starting out as space dwelling lifeforms (The Black Mass and the Catalyst Comets respectively) until they would crash to Earth in a large explosion that would wipe out the Dinosaurs

Both their physical forms would be released when man-made essences would make contact with their pure evilness (The fire arrow which the Emperor fired and the Mushroom Bomb used during). With this, their first attempt to conquer the world would begin. They would eventually be confronted by a legendary hero (The Emperor and Billy respectively) These two would seal our evils using a powerful weapon. (The sword given to the Emperor by the gods and The gauntlet Billy used to beat up the Lich). It's important to note that these would get destroyed later.

Eventually they would be freed from imprisonment and begin to wreak havoc again. Their old foes would be old and deshiveraled, needing a new hero to beat them. This hero would be a young warrior, the devoted good individual who would look out to our prior heroes. Our villains would have nigh-unkillable immortality that would render conventional weapons useless. (Arrows literally bounce off of Aku and The Lich catching the gauntlet and shushing Finn). The Heroes would wield their specific weaknesses. (Jack's katana and Princess Bubblegum's jumper respectively), before almost being killed by the heroes, but they managed to regenerate. (Aku regenerating his form and The Lich both possessing Princess Bubblegum and the Snail)

With now time to plan, they would use other individuals to get them information/objects of interest (Scaramouche and The Bear respectively) They also possess specific armies to fight for them, more general than anything. Also, they would torment the heroes emotionally by using dark reflections of individuals. (Aku creating a dark Jack to fuck with him and The Lich using Billy's rotting corpse to fuck with Finn and using Farmworld/Ice Finn)

They would become incredibly depressed after conquering the entire universe and finding destruction brings them nothing. (Aku starts to talk to himself after realising that he's conquered everything and that him and Jack are locked in a constant stalemate, with the Lich becoming depressed and still)

Both had children made from them (Ashi and Sweet P respectively) while their they would try to constantly manipulate them. (Aku training Ashi into being a warrior to kill Jack and The Lich speaking whispers to make Sweet P violent) they would go against the norm, befriending the hero. While they would seemingly be turned evil. (Aku possessing Ashi and Sweep P joining the Lich) they would overpower and help in permanently killing these evils.
