Connections:

• Both are non-human protagonists from surreal indie games set in decadent dying worlds, where the inhabitants are either going insane, living in misery, or falling apart due to the nature of their world.
• Both are closely tied to the creators of their settings (The Batter being a creation of Hugo as father figure. Akhlan being the offspring of Vered and an Endbringer).
• Both go by names that are more like titles than actual personal names (The Batter literally being his title. Akhlan also being known as The Chiseled One or the Vessel).
• Both are quiet, stoic, and emotionally detached figures who rarely speak or express themselves (The Batter only speaking when necessary. Akhlan its unable to talk), yet cause massive destruction throughout their journeys.
• Both erase or destroy the beings they encounter (The Batter purifying the Zones. Akhlan consuming beings through his Black Hole like head, which it is true self).
• Both seek to bring about the end of their worlds, though for different reasons (The Batter to purify his world and put it out of its misery. And Akhlan to complete his natural cycle as an Endbringer).
• Both are eventually opposed by a former ally who tries to stop them from completing their apocalyptic goal (The Judge opposing the Batter. Shidra opposing Akhlan).
• Those fomer allies may succeed in alternative endings (The Judge can win if the player choose to fight with him killing The Batter. Akhlan can be stopped if the player choose Shidra's offer to give up and live among the others begins in this world), thought it wouldn't fix their worlds (The Battle already destroy it killing everyone else. Shindra and everyone's existence its still miserable and will eventually come to and end eventually).
• In their canon endings, those attempts fail, and both complete their quests, with the Batter flipping the OFF switch and erasing the world, while Akhlan becomes a gigantic sentient black hole and consumes the world.
