Apocalypse + zombies + comedy + System + alternate setting
In life, he was a 996 wage slave. After turning into a zombie, he retained his full consciousness. He’s a drama queen and a snarky commentator with a wildly active inner monologue, but on the outside he’s expressionless, slow-moving, and just an ordinary zombie.
When he imagines himself as human, his body gradually becomes soft and warm, and even starts beating with a heartbeat.
When he imagines he has special effects, invisible-to-others bargain-bin effects really do appear whenever he attacks.
He gets so carried away by his own imagination that when he pictures himself as a “headless zombie,” he genuinely can’t stop himself from wanting to “take his head off.”
