Koalemos is a demon that was forced into a prototype of Sonic the Hedgehog 2 and used to test the game's outdated features and bugs, tormenting it in its entirety. until one day, it would make the game entirely unplayable forcing them to restart progress entirely, however, this copy would soon become self-aware, allowing the demon inside of it to kidnap the souls of those who tormented it, forcing them into its world to be tortured, while allowing it to expand its influence and allow others to know the true horrors of what sega is hiding.
