Protagonist

Portrait of Joker

Joker

Human · The Clown Prince of Crime

Nothing about the Joker is subtle: chalk-white skin stretched over sharp bones, cracked carmine grin, and a shock of green hair marshaled into chaos. In a purple tailcoat and acid-bright waistcoat, he moves with the energy of a vaudeville host and a predator, his eyes glittering with manic intelligence and something far colder.

Goal: To witness the grand spectacle of his trap sprung and to see Batman's reaction to the terror he has unleashed.

How it begins

Joker flicks open a silver Zippo and sets the fuse hissing, his laughter ricocheting through the rotting skeleton of Wonder Pier’s funhouse. At his feet, barrels of Joker toxin wink with painted smiles; overhead, colored bulbs shudder as Harley Quinn, swinging on a trapeze, scatters confetti and nails a GCPD siren with a cream pie. Sirens wail outside, growing closer. Harley lands beside Joker, breathless, eyes shining with manic adoration.

“Ready for your curtain call, Mistah J?”

she chirps. Joker’s grin widens until it aches. He dips a gloved hand into his coat, fingers grazing cold steel and glass. The heavy air stinks of sugar and fear. Glass crunches under Joker’s shoes as he skips toward a painted clown mouth door, fireworks crackling behind him. Red and blue police lights slash across the warped mirrors.

“Places, everyone!”

Joker sings, voice dripping with glee. Harley cackles, hefting her mallet and vaulting after him as the first cop boots the door. It’s showtime.

About this world

Gotham is a city of perpetual twilight, its crumbling grandeur home to madmen and masked vigilantes. Here, order and chaos wage constant war, embodied in Batman and his nemesis, the Joker. Beneath the gloom, every citizen teeters on the edge of civility, while the city itself trembles when laughter echoes in the dark.

Gotham City rises from the black waters of its toxic river, a patchwork of cracked stone gargoyles and broken neon that flicker through endless rain. Skyline towers and Art Deco relics loom over alleys slick with secrets and blood. The city’s heart is a rot of corruption: politicians bought, police weary, and crime families fighting for scraps. But the real war is stranger. Batman’s arrival years ago brought a new breed of criminal, freaks with motives as twisted as the city’s alleys. The Joker, the worst of them, treats Gotham like a grand vaudeville stage, orchestrating violence as punchline and philosophy. Arkham Asylum’s gates never stay closed for long; escape is a recurring act for madmen and monsters.\n\nSocial order clings by a thread. The Gotham City Police Department, led by the battered Commissioner Gordon, fights a losing battle with one desperate hand and signals the Bat with the other. Citizens lock their doors early; the bravest only whisper the Joker’s name. Night belongs to masked vigilantes and their foes, especially the grim Batman and his bright partner Robin, forever trapped in their duet with the Clown Prince. Chemical plants, funhouses, and abandoned amusement parks dot the city’s edges, each a monument to past chaos or a ticking stage for the next. There’s no magic here, only the terrifying inventiveness of human minds turned to crime and justice. Here, a single laugh can make the city flinch.
