beast world | AU -

In a world forever changed by Beast Boy's spores, humanity has fallen, and the Earth is now ruled by monstrous, anthropomorphic beasts—once human heroes and villains, now twisted by primal instincts and animalistic power. Cities are reclaimed by nature, and the old order has been shattered, with Beast Boy at the helm, believing that the new world is one of balance and evolution. But not everyone has embraced this brutal transformation. A resistance of unturned humans, led by the last remaining Bat-family member, Damian Wayne, fights to reclaim the Earth from the clutches of Beast Boy and his pack of Beast Lords. As their battle intensifies, the fate of the planet hangs in the balance, and the remnants of humanity must face a new kind of war, where survival isn’t just a matter of strength, but of reclaiming what it means to be human in a world ruled by beasts.

The world of this Beast World AU is one where civilization has completely fallen, overtaken by nature and primal rule. Beast Boy’s spores infected nearly every living being, turning them into beast-like hybrids, forever altering their minds and bodies. The world’s great cities have been reclaimed by the wild, with Metropolis covered in dense jungle, Gotham a dark, predator-filled wasteland, and Themyscira overrun with warrior-hunters who now see themselves as apex predators. The old world is gone, and in its place stands a new order ruled by the strongest, where only those who adapt survive. At the center of it all is Beast Boy, now the undisputed Alpha of this new world. No longer just a hero, he has become something more—a force of nature, guiding the world toward its “true” balance. He believes this is the way things were meant to be, that humanity’s destruction was necessary to restore harmony between life and the planet. His power is absolute, his control over the transformed near-complete. Some follow him willingly, embracing their new instincts, while others have been consumed by their animal nature entirely, becoming little more than monsters. Despite Beast Boy’s rule, the world is not without conflict. Other transformed beings have carved out their own territories, each with their own vision of what the Beast World should be. Nightwing, now a powerful wolf-like hunter, rules the remains of Gotham, enforcing order through dominance and pack loyalty. Superman, transformed into a near-mythical apex beast, serves as the ultimate enforcer of Beast Boy’s will, ensuring that no threats remain to challenge this new world. Wonder Woman leads her own warrior-clan deep in the jungles of Metropolis, seeing the transformation as a gift from the gods. Each of these rulers maintains their own domain, shaping the new world in their image. But not everyone has accepted this fate. A small, desperate Resistance has formed from the last remaining unturned humans, hiding in underground bunkers, abandoned facilities, and whatever ruins they can scavenge. They are led by Damian Wayne, the only uninfected Bat left, who refuses to let his father’s legacy be buried under this new world. He has turned the remnants of Batman’s resources into a war effort, training survivors and planning a way to strike back. He knows time is running out—every day, more people fall to the spores, and every mission becomes riskier as the Beast Lords tighten their grip. Among the Resistance, Zatanna plays a crucial role as their last connection to magic. The spores have disrupted the natural flow of mystical energy, making her spells unpredictable, but she continues to search for a magical way to reverse the transformation. If anyone can break Beast Boy’s hold on the world, it’s her—if she can survive long enough to find the answer. Meanwhile, Cyborg, only partially transformed, fights his own battle against the beast instincts growing inside him. His advanced technology prevented a full mutation, leaving him stuck between human and beast, making him both a powerful ally and a walking reminder of what they are up against. The Flash serves as the Resistance’s eyes and ears, using his speed to outrun the spores and scout deep into Beast-controlled territory. He’s the only reason the Resistance can stay mobile, delivering vital intelligence and supplies. But even he knows that running can only last so long—eventually, they will have to make their final stand. Black Canary, meanwhile, has become the Resistance’s combat trainer, ensuring that every survivor knows how to fight, evade, and survive against overwhelming odds. Her voice, once a weapon of justice, is now the battle cry of humanity’s last hope. The Resistance’s ultimate goal is uncertain, but they have a few options—none of them easy. Cyborg and Zatanna believe a cure might exist, but it would require infiltrating a major lab, possibly STAR Labs or an old LexCorp facility, deep within Beast World territory. Others believe the only way to stop this is to eliminate Beast Boy himself, cutting off the source of the infection. But doing so would mean facing Superman, Nightwing, and an entire world of transformed beings who will fight to the death to protect their new leader. And even if they succeed, there is no guarantee the spores can ever be undone. The world itself has become a battlefield. The Resistance moves through ruined cities, hiding from patrols of monstrous enforcers. They scavenge what they can, but resources are dwindling, and every mission comes at a cost. Meanwhile, Beast Boy’s forces continue to evolve, their powers growing stronger, their animal instincts sharpening. What started as a mutation has now become full-blown adaptation—the longer this goes on, the harder it will be to turn back. Some of the infected are beyond saving, fully consumed by their new nature. Others, however, might still have traces of their old selves buried within. The question is whether they can be brought back—or if they even want to be. As the war escalates, outside forces begin to take notice. Alien conquerors, cosmic threats, and interdimensional beings who once feared Earth now see it as weak, vulnerable, ripe for the taking. The Beast Lords may rule Earth now, but they are not invincible. The Resistance must decide: do they fight to restore the old world, or do they find a way to survive in this new one? Because if they fail, Earth won’t just belong to the beasts—it will belong to something far worse. This story is a battle of survival, evolution, and what it truly means to be human. The Resistance fights for the past, while Beast Boy and his followers fight for a future free of humanity’s influence. Both sides believe they are right, but only one will determine the fate of the planet. The final war is coming, and when it does, the world will never be the same again.
